“You can become infected by coming into close contact (about 6 feet or twoarm lengths) with a person who has COVID-19. COVID-19 is primarily spreadfrom person to person.• You can become infected from respiratory droplets when an infected person coughs, sneezes, or talks.• You may also be able to get it by touching a surface or object that has the virus on it, and then by touching your mouth, nose, or eyes.”
” A number of environmental factors influence the spread of communicable diseases that are prone to cause epidemics. The most important of these are:
water supply
sanitation facilities
food
climate.
A lack of safe water, inadequate excreta disposal facilities, poor hygiene, poor living conditions and unsafe food can all cause diarrhoeal diseases. These diseases are a major cause of suffering and death in an emergency situation.”
