QUOTE FOR THE WEEKEND:

“Indeed, music is a potent tool for the future of precision medicine. As the scientific community continues to elucidate the emotional landscape of music, as well as how it differs from listener to listener, new methods for alleviating disease severity and improving overall well-being await both patients and otherwise healthy members of the general public.

The effect of music on our brains has clinical implications as well. Growing evidence suggests, for example, that listening to Mozart’s Sonata for Two Pianos in D Major can reduce the frequency of seizures in some people with epilepsy.

Identifying the exact type of music able to provoke a particular cognitive, motor, or emotional response, there could be progress toward healing, improving, or compensating for disrupted brain function in various diseases. An increased understanding of brain mechanisms can facilitate this.

David Silbersweig, the Stanley Cobb Professor of Psychiatry at HMS and chair emeritus of the Department of Psychiatry at Brigham and Women’s Hospital, is interested in uncovering answers to these questions. A leader in functional neuroimaging research in psychiatry, he investigates how brain regions and networks function when we perceive, think, feel, and act.

“We seem to be very much tuned for music”

“It’s at the systems level with brain imaging that you can directly correlate mental states and brain states — and measure them.” Silbersweig says. “Neuroimaging provides a noninvasive way of correlating brain structural and functional abnormalities with specific aspects of music processing.”

STRESS

Another factor in music’s ability to reduce pain likely stems from its competition for our attention. “If you’re thinking about something else, then you’re not thinking about your pain, and you feel less pain,” says psychologist David Bradshaw, who studies pain relief at the University of Utah’s Pain Research Center.  Bradshaw’s research shows that the more actively engaged a person is in music, the less pain they feel. For instance, a group of non-musicians asked to listen for errors in a musical passage reported less pain when receiving small electric shocks than those who passively listened to the music. 

Other work out of Bradshaw’s lab suggests that certain personality factors, such as a propensity toward anxiety or the ability to become easily absorbed in activities, may lead individuals to experience greater relief from engaged music listening. These findings suggest that physicians should consider patients’ personalities when recommending pain treatment programs. 

Listening to a song can have a real effect on various parts of the brain, with studies showing that areas responsible for aspects, such as memory and vision, can ‘light up’ in response to music.

“There’s a very wide range of reactions in the body and mind to music, and brain imaging studies have shown that various parts of the brain may be activated by a piece of music.”,  says Dr Victoria Williamson, lecturer in psychology at Goldsmith’s College, London.

‘For example, a recent study in Canada showed that there’s a real causal relationship between music and the reward system, a core part of the brain that reacts to stimuli, which are good for us – food, light, sex for example – and reinforces these behaviors meaning that we do them more.’

Researchers at McGill University in Montreal showed that listening to pleasurable music of any description induced ‘musical chills’, which triggered the release of the feel-good chemical dopamine.

“We all know from our own individual experiences that listening to music can affect mood”, says Bridget O’Connell, head of information at the mental health charity Mind.

Music may even be able to help you concentrate.

A new ‘digital tonic’ called Ubrain, which can be downloaded onto smartphones, claims to be able to help people focus, energise, wake up as well as relax.

The process uses two different beats in each ear to create a third ‘perceived’ beat (a binaural beat), which can stimulate certain activity in the brain.

“By helping the brain cortex to generate specific brain waves, we can induce different states of alertness, depending on what we aim to do”, explains Paris-based clinical psychologist Brigitte Forgeot.

If we’re feeling anxious or stressed, we can encourage our cerebral cortex to produce slow alpha-frequency brain waves, while on the other end of the scale, if we help our cortex to produce faster beta waves, we will be better equipped to concentrate and focus our attention on a fairly lengthy task.

PREVENTION OF DISEASE by increasing the immunity through music—AMAZING!

Can listening to music actually help prevent disease? Some researchers think so.

Wilkes University researchers looked at how music affects levels of IgA — an important antibody for our immune system’s first line of defense against disease. Undergraduate students had their salivary IgA levels measured before and after 30 minutes of exposure to one of four conditions — listening to a tone click, a radio broadcast, a tape of soothing music or silence. Those students exposed to the soothing music had significantly greater increases in IgA than any of the other conditions, suggesting that exposure to music (and not other sounds) might improve innate immunity.

Another study from Massachusetts General Hospital found that listening to Mozart’s piano sonatas helped relax critically ill patients by lowering stress hormone levels, but the music also decreased blood levels of interleukin-6 — a protein that has been implicated in higher mortality rates, diabetes and heart problems.

According to a 2013 meta-analysis, authors Mona Lisa Chanda and Daniel Levitin concluded that music has the potential to augment immune response systems, but that the findings to date are preliminary. Still, as Levitin notes in one article on the study, “I think the promise of music as medicine is that it’s natural and it’s cheap and it doesn’t have the unwanted side effects that many pharmaceutical products do.”

FOR THE DISEASED PATIENTS

Music can actually have a significant positive impact on patients with long-term illnesses, such as heart disease, cancer and respiratory conditions (Home, in nursing homes, hospitals, the office, etc…)

Numerous trials have shown that music can help lower heart rate, blood pressure and help relieve pain, anxiety and improve patient quality of life.

“Music can be incredibly useful for somebody who is in a situation where they have lost a lot of control from their external environment – say they are in hospital for a long period of time with a serious illness and less able to move around,” says Dr Williamson.

‘It can give them a sense of control back, as well as creating a calm personal atmosphere and blocking out some of the disturbances around the patient.

According to sports researchers Peter Terry and Costas Karageorghis, “Music has the capacity to capture attention, lift spirits, generate emotion, change or regulate mood, evoke memories, increase work output, reduce inhibitions and encourage rhythmic movement — all of which have potential applications in sport and exercise.”

QUOTE FOR FRIDAY:

“If you want to firm up your body, head to the gym. If you want to exercise your brain, listen to music.

There are few things that stimulate the brain the way music does. If you want to keep your brain engaged throughout the aging process, listening to or playing music is a great tool. It provides a total brain workout.

Research has shown that listening to music can reduce anxiety, blood pressure, and pain as well as improve sleep quality, mood, mental alertness, and memory.

Experts are trying to understand how our brains can hear and play music. A stereo system puts out vibrations that travel through the air and somehow get inside the ear canal. These vibrations tickle the eardrum and are transmitted into an electrical signal that travels through the auditory nerve to the brain stem, where it is reassembled into something we perceive as music.

Johns Hopkins researchers have had dozens of jazz performers and rappers improvise music while lying down inside an fMRI (functional magnetic resonance imaging) machine to watch and see which areas of their brains light up.

Music is structural, mathematical and architectural. It’s based on relationships between one note and the next. You may not be aware of it, but your brain has to do a lot of computing to make sense of it.”

Pain relief with a pain relieving nature-MUSIC.

The improvement of physical wellbeing through music isn’t only about perceived pain relief. Studies show that playing music for patients before, during, and after medical procedures can help lower blood pressure, reduce anxiety and stress, ease muscle tension, and more.  At the Chronic Pain Care Center at the Rehabilitation Institute of Chicago, music therapy is part of the array of techniques that patients learn to help control their pain, according to osteopathic physician Steven Stanos, medical director of the center. As Stanos sees it, there is no reason not to take time to listen to music.  “What we’ve learned from our pain patients is that any intervention that can be distracting, relaxing, and enjoyable — whether it’s music or another therapy — can decrease the experience of pain,” Stanos says. 

Listening to a song can have a real effect on various parts of the brain, with studies showing that areas responsible for aspects, such as memory and vision, can ‘light up’ in response to music.

‘There’s a very wide range of reactions in the body and mind to music, and brain imaging studies have shown that various parts of the brain may be activated by a piece of music,’ says Dr Victoria Williamson, lecturer in psychology at Goldsmith’s College, London.

Researchers at McGill University in Montreal showed that listening to pleasurable music of any description induced ‘musical chills’, which triggered the release of the feel-good chemical dopamine.

Music so impacting to our brain that music is even considered having a pain-relieving nature, scientists are exploring how the brain processes music during pain. Look at when we go to the doctor or better the dentist. More are less out to go to the dentist as opposed to the MD since a doctor’s visit doesn’t include the day of the visit or soon later a drill going in out mouth to take care of a cavity or worse Root Canal Surgery, you get the picture. Remember when you have or if you still do regularly go to the dentist there is always soft music in the background. This is because it calms the body through how the brain reacts to soft music as opposed to hard rough music.

When the body encounters something painful — you step on a tack or having a drill applied to a cavity with no novacaine if allergic or the patient just refuses the medication, for instance — electrochemical signals travel from the site of the injury to the spinal cord and on to the brain. There, several brain regions work together to process pain signals — ultimately resulting in the conscious experience of, “Ow, that hurts!” In contrast, brain scans reveal that listening to pleasing music increases activity in parts of the brain’s reward center. 

“Pleasant music triggers the release of the brain chemical dopamine,” explains Robert Zatorre, of McGill University, who studies emotion and music. This change “is strongly associated with other rewarding and motivating stimuli, such as food, sex, and certain addictive drugs,” Zatorre adds. Scientists believe that music’s ability to make you feel good may be one way it helps to alleviate pain.

PLEASING TUNES = RELIEVING PAIN

Studies also suggest that how good a song makes you feel affects your perception of pain. Although musical taste is subjective, there are common features of music that evoke fairly universal responses. For instance, most people find musical consonance (harmonies or chords) to be pleasant and dissonance (clashing notes) to be unpleasant.

When scientists asked study volunteers to evaluate pain while they listened to different types of music, researchers found that people who listened to excerpts of music judged by most to be pleasant (such as the Romantic music piece “The Blue Danube Waltz“) reported less pain than those who listened to unpleasant music (such as Steve Reich’s modern classical piece “Pendulum Music“). The more pleasing the listeners found the music to be, the less pain they felt. 

Other studies suggest that music can interfere with pain signals even before they reach the brain — at the level of the spinal cord. In these studies, scientists examine how different types of music change the withdrawal reflex: an involuntary organized entirely in the spinal cord. 

In one study, scientists measured how forcefully volunteers withdrew their feet after being mildly electrically zapped on an ankle as they listened to music. Compared with pleasant music, unpleasant music resulted in stronger leg reflexes and greater reports of pain. 

Psychologist Mathieu Roy, of the University of Colorado, Boulder, who conducted the study, says these results suggest that music can prevent the transmission of pain signals from the spinal cord to the brain.

 

QUOTE FOR THURSDAY:

“Since 2006, two UCF professors — neuroscientist Kiminobu Sugaya and world-renowned violinist Ayako Yonetani — have been teaching one of the most popular courses in The Burnett Honors College. “Music and the Brain” explores how music impacts brain function and human behavior, including by reducing stress, pain and symptoms of depression as well as improving cognitive and motor skills, spatial-temporal learning and neurogenesis, which is the brain’s ability to produce neurons. Sugaya and Yonetani teach how people with neurodegenerative diseases such as Alzheimer’s and Parkinson’s also respond positively to music.

“Usually in the late stages, Alzheimer’s patients are unresponsive,” Sugaya says. “But once you put in the headphones that play [their favorite] music, their eyes light up. They start moving and sometimes singing. The effect lasts maybe 10 minutes or so even after you turn off the music.”

This can be seen on an MRI, where “lots of different parts of the brain light up,” he says. We sat down with the professors, who are also husband and wife, and asked them to explain which parts of the brain are activated by music.”

We can usually pick if a piece of music is particularly happy or sad, but this isn’t just a subjective idea that comes from how it makes us feel. In fact, our brains actually respond differently to happy and sad music. Even short pieces of happy or sad music can affect us.

When we hear a form of music we actually match the tone of the music with our mood or reaction to it. This means that sometimes we can understand the emotions of a piece of music without actually feeling them, which explains why some of us find listening to sad music to enjoyable, rather than depressing or sad to others.

We all like to pump up the tunes when we’re powering through our to-do lists, right? But when it comes to creative work, loud music may not be the best option.

It turns out that a moderate level of noises is the sweet level for creativity. Even more than low noise levels, ambient noise apparently gets our creative juices flowing, and doesn’t put us off the way high levels of noise does.

The way this works is that moderate noise levels increase processing difficulty which promotes abstract processing, leading to higher creativity. In other words, when we struggle (just enough) to process things as we normally would, we resort to more creative approaches.

In high noise levels, however, our creative thinking is impaired because we’re overwhelmed and struggle to process information efficiently.

This is very similar to how temperature and lighting can affect our productivity, where paradoxically a slightly more crowded place can be beneficial.

Of course, generalizing based on some studies is very hard. However looking at the science of introverts and extroverts, there is some clear overlap showing the following:

To break it down, here is the connection they has been found about people (again remember this is generally speaking):

  • Blues fans have high self-esteem, are creative, outgoing, gentle and at ease
  • Jazz fans have high self-esteem, are creative, outgoing and at ease
  • Classical music fans have high self-esteem, are creative, introvert and at ease
  • Rap fans have high self-esteem and are outgoing
  • Opera fans have high self-esteem, are creative and gentle
  • Country and western fans are hardworking and outgoing
  • Reggae fans have high self-esteem, are creative, not hardworking, outgoing, gentle and at ease
  • Dance fans are creative and outgoing but not gentle
  • Indie fans have low self-esteem, are creative, not hard working, and not gentle
  • Bollywood fans are creative and outgoing
  • Rock/heavy metal fans have low self-esteem, are creative, not hard-working, not outgoing, gentle, and at ease
  • Chart pop fans have high self-esteem, are hardworking, outgoing and gentle, but are not creative and not at ease
  • Soul fans have high self-esteem, are creative, outgoing, gentle, and at ease.  Playing music expands our thinking. We generally assume that learning a musical instrument can be beneficial for kids, but it’s actually useful in more ways than we might expect.  Studies have shown that children who had three years or more musical instrument training performed better than those who didn’t learn an instrument in auditory discrimination abilities and fine motor skills.
  • Instrument playing is a form of exercise that is great for your health as opposed to sitting watching t.v. where no creativity or imagining or brain concentrating takes place.
  • It seems that unfamiliar, or uninteresting, music is best for safe driving. Reason: Less Distracted.

Research on the effects of music during exercise has been done for years. In 1911, an American researcher, Leonard Ayres, found that cyclists pedaled faster while listening to music than they did in silence.

This happens because listening to music can drown out our brain’s cries of fatigue. As our body realizes we’re tired and wants to stop exercising, it sends signals to the brain to stop for a break. Listening to music competes for our brain’s attention, and can help us to override those signals of fatigue, though this is mostly beneficial for low- and moderate-intensity exercise. During high-intensity exercise, music isn’t as powerful at pulling our brain’s attention away from the pain of the workout.

Not only can we push through the pain to exercise longer and harder when we listen to music, but it can actually help us to use our energy more efficiently. A 2012 study showed that cyclists who listened to music required 7% less oxygen to do the same work as those who cycled in silence.

Some recent research has shown that there’s a ceiling effect on music at around 145 bpm, where anything higher doesn’t seem to add much motivation, so keep that in mind when choosing your workout playlist.

We all have a genre; for those wondering what is that actually it is a category of artistic, musical, or literary composition characterized by a particular style, form, or content

“The kind of music one listens to determines one’s reaction to it. No genre is harmful, but there is a preferable choice in different situations. For instance, studies have found that percussion stimulates the left side of the brain, so if one were solving Mathematics problems, or having to reach a logical conclusion, that music would be beneficial. Similarly, for an artiste, instrumental music or Soul would work better,” explains Khurana.

According to Dr Shaan Manohar, ENT specialist, Nanavati Hospital, “Japan has done a study on applying music to water as it freezes and check the patterns of crystals formed. It was concluded that loud drumbeats and music with violent poetry tend to have a destructive effect on the crystals versus Classical music, soft love tracks or devotional lyrics had an enhancing effect on the crystal formation. Loud drumbeats are also known to interfere with the pace of the heart in the very young and the elderly. It is a known fact that listening to Classical music enhances the mathematical ability of a growing child. Also, chanting helps release endorphins in the body creating a calm person, full of positive energy.”

QUOTE FOR WEDNESDAY:

“Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury. Typically, your body will naturally dissolve the blood clot after the injury has healed. Sometimes, however, clots form on the inside of vessels without an obvious injury or do not dissolve naturally. These situations can be dangerous and require accurate diagnosis and appropriate treatment.

Clots can occur in veins or arteries, which are vessels that are part of the body’s circulatory system. While both types of vessels help transport blood throughout the body, they each function differently. Veins are low-pressure vessels that carry deoxygenated blood away from the body’s organs and back to the heart. An abnormal clot that forms in a vein may restrict the return of blood to the heart and can result in pain and swelling as the blood gathers behind the clot.”

 

American Society of Hematology (https://www.hematology.org/education/patients/blood-clots)

 

Why blood clotting is a vital important part of the bloodstream through platelets and how it works!

Why blood clotting is a vital important part of the bloodstream through platelets and how it works is what would we will review first to understand disseminated intra-vascular coagulopathy (DIC).  It is a vital important process of the platelets that make up part of our bloodstream cells that help prevent excessive bleeding or excessive hemorrhage.

In how clotting works is platelets, which is a type of blood cell, with plasma that is in our liguid part of blood work together to stop the bleeding by forming a clot over the injury (a bruise or cut in the skin) which stops the bleed.  Both veins and arteries transport our blood (both solids=cells) and the liguid (the plasma) that are read by out hematocrit and hemoglobin in a CBC=complete blood count which also tell the MD our reading of red/white blood cell counts with platelets.  Typically, your body will dissolve the clot after the injury has healed.  However, there are times clots form on the inside of our vessels (there are variables of why this would happen that are discussed later in this topic).  These situations can be dangerous and put the pt at risk for problems.  This needs to be diagnosed and given appropriate treatment by your doctor or MD specialist.

Clots can occur in our veins or arteries and can occur is various areas causing

1-DVT=Deep Vein Thrombosis

DVT commonly in our large veins that are commonly found in our lower extremities and less likely in our upper extremities or pelvic region or other areas where there are large veins. The problem (one the clot is wedged and stuck against the vessel) with this the clot blocks off circulation to the area below the clot to a percentage low to 100% blockage.  This is where in the skin there is pain to necrosis below the clot area (for this to happen it takes numerous hours-pain to days-changes in skin color or week or more-necrosis depending on the blockage).   The greater the blockage is the quicker the symptoms arise no matter where the clot is.  It is estimated that each year DVT affects as many as 900,000 people in the United States by the American Heart Association and kills up to 100,000 by the Centers for Control and Prevention (CDC).

-Paget-Schroetter Syndrome (PSS) – It’s a rare kind of DVT that typically happens to a young, healthy person who plays sports that use the upper arms a lot, like swimming and baseball. The vein can get squeezed by the muscles around it. This pressure, along with repeated movements, can cause a clot in your shoulder. Symptoms like swelling, chest pain, and a blue color to your skin may come on suddenly. PSS can be serious if it’s not treated right away.

2-Atrial Fibrillation

Another area where blood clotting can occur is in the heart.   We see commercials all the time about atrial fibrillation=irregular rhythm with the heart beat.  In the commercial its usual an add for a med called a anticoagulant that does the opposite of what platelets do=clotting to prevent this problem from happening in the heart which indirectly prevents clotting in all vessels as well.  The med thins the blood.   The major problem with this diagnosis, atrial fibrillation without being on a anticoagulant, is blood can pool in the heart causing a clot to form in the heart and at some point, especially when the rhythm is rapid and more irregular that usual=RVR-rapid ventricular rate over 100 beats per minute and usually over 130 to over 150, the clot can break off.

3-Heart Attack

Know this, more often than not, a broken piece of plaque within the arteries triggers the formation of a blood clot. This blood clot is the reason for a heart attack. As the blood clot potentially restricts the flow of blood and oxygen to the heart, depending on the severity, the heart attack can cause sudden death.

There are other areas where blood can form clots but not as common in what was mentioned above. Blood clots can arise anywhere in your body. They develop when blood thickens and clumps together. When a clot forms in a deep vein in the body, it’s called deep vein thrombosis. Deep vein blood clots typically occur in the lower leg or thigh.

The biggest consequence of any blood clot no matter where it is it can break off in time for many especially with a DVT.   Than there is  atrial fibrillation patients not on a anti-coagulant or anti-platelet like Coumadin, Eliquis, heparin, and lovenox to Plavix, Brilinta, Ticlid and Integrilin with other medications (listed commonly used in my nursing career) it puts them at risk for a clot to break off in the heart due to pooling blood causing a clot formation and when it breaks off it could go the the lungs causing pulmonary embolus or the brain a stroke.

For understanding the meaning lets review; Deep vein thrombosis (DVT) is a condition in which a blood clot develops in the deep veins, usually in the lower extremities. A pulmonary embolism (PE) occurs when a part of the DVT clot breaks off and travels to the lungs, which can be life-threatening. Venous thromboembolism (VTE) refers to DVT, PE, or both.

When a clot breaks off it floats now in the bloodstream and can in time make it back to the heart putting the pt at risk for a heart attack if it didn’t get stuck elsewhere, like going to the lungs putting the pt at risk for a pulmonary embolism or now in circulation making it to the brain putting the pt at risk for a stroke!  Clots are common in making the strokes in what we call ischemic stroke and another name “silent stroke”.   Silent strokes are much more common than strokes that cause classic symptoms such as face drooping, arm weakness and speech difficulty and affect nearly 800,000 Americans each year. According to the statement, one in four people over 80 have one or more silent strokes.

 

QUOTE FOR TUESDAY:

“The novel coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), which causes COVID-19, is part of a large family of coronaviruses. These viruses are named for the “crown” of spikes on the virus particle’s spherical surface, which help the virus attach to cells and infect them.

Coronaviruses are found in humans and in other animal species, including bats, cats, and livestock. Some coronaviruses found in animals can evolve and infect people. Diseases that can be transmitted from animals to people, including diseases that are transmitted by viruses, are called zoonotic diseases.

Common coronaviruses can cause mild illness, but other coronaviruses—including MERS-CoV, which causes Middle East Respiratory Syndrome (MERS), SARS-CoV, which causes Severe Acute Respiratory Syndrome (SARS), and the novel coronavirus SARS-CoV-2 which causes COVID-19 and this can be fatal.”

American Museum of Natural History (https://www.amnh.org/explore/covid-19-science)

How are SARS,MERS, COVID 19 closely related, comparison of fatality rates & why so many vaccine changes with Covid-19? Their is logic scientifically behind it.

SARS, MERS, and Corona Viruses  are all caused by some CORONA VIRUS!

Through the National Library of Medicine they state:

“In the 21st century, we have seen a total of three outbreaks by members of the coronavirus family. Although the first two outbreaks did not result in a pandemic, the third and the latest outbreak of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) culminated in a pandemic. This pandemic has been extremely significant on a social and international level. As these viruses belong to the same family, they are closely related. Despite their numerous similarities, they have slight distinctions that render them distinct from one another!”

Both COVID-19 and SARS are caused by coronaviruses. The virus that causes SARS is known as SARS-CoV, while the virus that causes COVID-19 is known as SARS-CoV-2.  So what does this mean?  A severe respiratory illness that is caused by a coronavirus (Severe acute respiratory syndrome-related virus of the genus Betacoronavirus

SARS is caused by Betacoronavirus that is one of four genera of coronaviruses. Member viruses are enveloped, positive-strand RNA viruses that infect mammals, including humans.  The first generation of covid.

COVID-19, which is caused by the 2019 coronavirus, has been dominate news starting 2019. However, you may have first become familiar with the term coronavirus during the severe acute respiratory syndrome (SARS) outbreak in 2003.

Both COVID-19 and SARS are caused by coronaviruses. The virus that causes SARS is known as SARS-CoV, while the virus that causes COVID-19 is known as SARS-CoV-2. There are also other types of human coronaviruses.

Despite similar names, there are several differences between the coronaviruses that cause COVID-19 and SARS.

“Abstract

Background: Middle East Respiratory Syndrome (MERS) is a viral respiratory illness that can spread from camels to people through direct physical .  The MERS virus causes flu-like symptoms, with most patients developing pneumonia as a secondary infection. MERS is caused by a virus in the coronavirus family, and the syndrome is also called MERS-Coronavirus (MERS-CoV). MERS is passed primarily to people from infected camels.

Aims: To provide a review of the differences in pathogenesis, epidemiology and clinical features of COVID-19, SARS and MERS.

Sources: The most recent literature in the English language regarding COVID-19 has been reviewed, and extracted data have been compared with the current scientific evidence about SARS and MERS epidemics.

Content: COVID-19 seems not to be very different from SARS regarding its clinical features. The pathogenesis of human coronaviruses is mostly determined by viral particle binding to specific receptors rather than viremia.  However, it has a fatality rate of 2.3%, lower than that of SARS (9.5%) and much lower than that of MERS (34.4%). The possibility cannot be excluded that because of the less severe clinical picture of COVID-19 it can spread in the community more easily than MERS and SARS. The actual basic reproductive number (R0) of COVID-19 (2.0-2.5) is still controversial. It is probably slightly higher than the R0 of SARS (1.7-1.9) and higher than that of MERS (<1). A gastrointestinal route of transmission for SARS-CoV-2, which has been assumed for SARS-CoV and MERS-CoV, cannot be ruled out and needs further investigation.

Implications: There is still much more to know about COVID-19, especially as concerns mortality and its capacity to spread on a pandemic level. Nonetheless, all of the lessons we learned in the past from the SARS and MERS epidemics are the best cultural weapons with which to face this new global threat since 2019 in China and 2020 in the USA.

Middle East Respiratory Syndrome-MERS:

The MERS virus causes flu-like symptoms, with most patients developing pneumonia as a secondary infection. MERS is caused by a virus in the coronavirus family, and the syndrome is also called MERS-Coronavirus (MERS-CoV). MERS is passed primarily to people from infected camels.  The first generation of Covid.

Key facts:

  • Middle East respiratory syndrome (MERS) is a viral respiratory disease caused by Middle East respiratory syndrome coronavirus (MERS‐CoV) that was first identified in Saudi Arabia in 2012.
  • Coronaviruses are a large family of viruses that can cause diseases ranging from the common cold to Severe acute respiratory syndrome (SARS), MERS and Coronavirus disease-2019 (COVID-19).
  • Typical MERS symptoms include fever, cough and shortness of breath. Pneumonia is common, but MERS patients may not always develop this condition. Gastrointestinal symptoms, including diarrhoea, have also been reported among MERS patients.
  • Approximately 35% of MERS cases reported to WHO have died.
  • MERS-CoV is a zoonotic virus, meaning it is transmitted between animals and people. MERS-CoV has been identified and linked to human infections in dromedary camels in several Member States in the Middle East, Africa and South Asia.
  • Human-to-human transmission is possible and has occurred predominantly among close contacts and in health care settings. Outside the health care setting, there has been limited human-to-human transmission.

Covid-19=Corona Virus Disease

This is the third serious Coronavirus outbreak that in less than 22 years, following SARS in 2002–2003 and MERS in 2012. While human strains of Coronavirus are associated with about 15% of cases of the common cold, the SARS-CoV-2 may present with varying degrees of severity, from flu-like symptoms to death. It is currently believed that this deadly Coronavirus strain originated from wild animals at the Huanan market in Wuhan, a city in Hubei province. Bats, snakes and pangolins have been cited as potential carriers based on the sequence homology of CoV isolated from these animals and the viral nucleic acids of the virus isolated from SARS-CoV-2 infected patients.

Extreme quarantine measures, including sealing off large cities, closing borders and confining people to their homes, were instituted in January 2020 to prevent spread of the virus, but by that time much of the damage had been done, as human-human transmission became evident.

The purpose for these measures are there are three primary ways to transmit the virus, including close person-to-person contact (droplet transmission), aerosol transmission, and transmission by touch=Purpose for mask, and if close to the patient with Covid-19 present gowns, gloves at least with the mask.

While these quarantine measures are necessary and have prevented a historical disaster along the lines of the Spanish flu, earlier recognition and earlier implementation of quarantine measures may have been even more effective. Lessons learned from SARS resulted in faster determination of the nucleic acid sequence and a more robust quarantine strategy. However, it is clear that finding an effective antiviral and developing a vaccine are still significant challenges.”

What’s the concern about COVID-19 variants? Are they more contagious?

Concern over variants, sometimes called strains, of the virus that causes COVID-19 is based on how the virus might change. A virus could get better at infecting people, spread faster or cause people to get sicker.

As a virus infects a group of people, the virus copies itself. During this process the genetic code can randomly change in each copy. These changes are called mutations.

Some mutations don’t have any effect on the virus.

But other mutations can:

  • Make the virus better at infecting a person’s cells, causing serious illness.
  • Make the virus better at avoiding the immune system.
  • Cause tests for the virus to be less accurate.
  • Cause vaccines to not work as well.
  • Make medicine used to prevent or treat COVID-19 stop working or not work as well.

If a mutation changes how a virus acts in a group of people, it’s called a variant. Scientists across the world track the changes in the virus variants that cause COVID-19.

Omicron

The main variant in the United States is omicron. This variant spreads more easily than the original virus that causes COVID-19 and the delta variant. But omicron seems to cause less severe disease.

Omicron has a few major offshoots, also called sublineages. Together the omicron variants make up nearly all COVID-19 infections in the United States.

The Omicron variant, which emerged in November 2021, has many lineages. New lineages continue to emerge and spread in the United States and globally. We have the tools to fight variants. Take steps to protect yourself and others.

WHY SO MANY VACCINES FOR COVID-19?

First introduced in December 2020, the original COVID mRNA vaccines from both Pfizer and Moderna protected against the original SARS-CoV-2 virus.

Than with continuing to study COVID – 19 with people infected with it we came across the Omicron variant/strain.

The vaccines were replaced in September 2022 by “bivalent” vaccines, which targeted both the original virus and Omicron variants BA.4 and BA.5 to control the spread of COVID-19 to prevent another epidemic.

This is why so many vaccines; which many people are resistive to get to their reason in not understanding why the vaccines were pushed with not knowing about the logic behind the different variants needing a new vaccine to kill it!
