Principles of Infectious Disease Epidemiology Quiz

Infectious diseases are not transmitted through genetic inheritance.

Epidemiology aims to understand, prevent, and manage the transmission of infectious diseases.

Zoonotic diseases are those that can be transmitted from animals to humans, such as rabies.

Bats serve as the primary reservoir host for the Ebola virus.

Improved sanitation actually reduces the risk of infectious disease emergence.

Incidence measures the rate of new cases of a disease within a population.

R0 indicates how contagious an infectious disease is within a susceptible population.

Vector-borne diseases are transmitted through vectors like mosquitoes, as in the case of malaria.

Herd immunity occurs when a large proportion of a population becomes immune to a disease, reducing its spread.

Quarantine involves restricting the movement of individuals who have been exposed to a contagious disease to prevent its spread.

An epidemic refers to a sudden increase in the number of cases of a disease within a specific population.

Smallpox is the only infectious disease eradicated globally through vaccination campaigns.

While antibiotics treat infections, they are not a preventive measure to control infectious diseases at a population level.

Antimicrobial resistance primarily results from overuse or misuse of antibiotics, not genetic predisposition.

Developing countries often lack advanced healthcare infrastructure, which can limit disease surveillance, prevention, and treatment.
