Using the design and key of the figure as a model, select all statements that represent changes that occurred when the novel coronavirus appeared in the population. There was protection for the most vulnerable people in the population due to herd immunity. O Complex chains of disease transmission (red arrows) appeared. There were more unvaccinated people (gray), more infected people (red), and no vaccinated people (blue) in the population. O There was community spread of the infectious disease due to a lack of herd immunity. O Disease outbreaks were contained due to herd immunity.

Pathogenicity

Infection and Transmission

The infections are generated by the pathogenic organisms present in the environment. They maintain the capacity to invade a host body and establish colonies. A disease caused by such infectious agents is called a communicable disease or transmissible disease. These diseases spread through diverse means including blood, food, water, air, or vectors.
