Describe three types of reservoirs of infectious disease in humans. Give an example disease for each type of reservoir
What will be an ideal response?
for a pathogen to enter a new host, it must survive in some site from which it can infect the new host. These sites are considered reservoirs, which include the following:
1. Animal reservoirs, such as domestic or wild animals. Examples: Lyme disease, rabies, West Nile fever
2. Human carriers, which are individuals who are infectious and may be either asymptomatic or symptomatic. Examples: AIDS, tuberculosis, typhoid fever
