Question

what are the factors involved during spread of pathogens?

Answer 1

There are several kinds of factors that are involved during the pathogens spread and transmission. They include:

1. Environmental factors (water supply, food quality, sanitation facilities, climate and weather characteristics);
2. Biological factors (areal of the infection-transmitting vectors, individual susceptibility to infection, high virulence of the pathogen);
3. Social factors (density of the population, financial income, frequent contacts between individuals).
