Which of the following is NOT an example of a virus?

• A. Yellow Fever
• B. Influenza
• C. Malaria
• D. Smallpox

Answer: (C)

Malaria is caused by a parasite, specifically a protozoan from the Plasmodium genus, and not by a virus. This differentiates it from the other options, all of which are viral illnesses. Yellow Fever, Influenza, and Smallpox are caused by viruses: Yellow Fever is caused by the Yellow Fever virus, Influenza is caused by influenza viruses, and Smallpox is caused by the variola virus. The fundamental distinction lies in the type of pathogen responsible for the diseases; while viruses are microscopic organisms that require a host to replicate, Malaria's causative agent is a living parasite that can reproduce independently within its host. Therefore, recognizing the classification of these diseases helps in understanding their transmission, treatment, and prevention strategies.
