Front

What is a biological vector?

Back

A biological vector is an organism that carries and transmits pathogens to other living organisms. Example: A mosquito carrying malaria.

Front

What is an example of a mechanical vector?

Back

A mechanical vector is an organism that carries pathogens on its body without being infected. Example: A housefly carrying dysentery on its feet.

Front

What is the role of the Anopheles mosquito in disease transmission?

Back

The Anopheles mosquito is a biological vector that spreads malaria by carrying the Plasmodium parasite.

Front

What is the definition of a reservoir in the context of disease transmission?

Back

A reservoir is a natural habitat where a pathogen lives and multiplies, which can be an animal, human, or environment.

Front

What is the significance of reducing standing water in controlling mosquito populations?

Back

Reducing standing water eliminates breeding sites for mosquitoes, thereby decreasing their population and the risk of diseases like malaria.

Front

What was the year of the modern H1N1 (swine flu) pandemic?

Back

The modern H1N1 (swine flu) pandemic occurred in 2009.

Front

What is the difference between a biological vector and a mechanical vector?

Back

A biological vector is involved in the life cycle of the pathogen and can become infected, while a mechanical vector carries pathogens externally without being infected.

Front

What is the mode of transmission for rabies?

Back

The mode of transmission for rabies is typically through bites from infected animals, such as dogs.

Front

What is the role of community outreach in disease prevention?

Back

Community outreach educates and engages the public in practices that reduce disease transmission, such as eliminating breeding grounds for vectors.

Front

What is an infectious agent?

Back

An infectious agent is a pathogen, such as a virus, bacterium, or parasite, that can cause disease.
