In vectorborne transmission, what is an example of a disease transmitted by an infected organism?

Vectorborne transmission refers to the spread of diseases through specific organisms, often insects, that carry pathogens from one host to another. In the case of malaria, it is transmitted by the Anopheles mosquito, which carries the Plasmodium parasite that causes the disease. This mode of transmission highlights how an infected organism plays a critical role in the lifecycle of the pathogen, as it not only carries the infectious agent but also facilitates its entry into a new host.

In contrast, diseases like influenza, HIV/AIDS, or hepatitis are primarily spread through direct contact, respiratory droplets, or bodily fluids rather than through a vector. Influenza is spread via airborne droplets from one person to another, HIV/AIDS is transmitted through blood and sexual contact, and hepatitis is often spread through contact with infected bodily fluids or contaminated surfaces. None of these involve a biological vector carrying an infectious agent, as seen in malaria. Thus, malaria is the prime example of a disease in the context of vectorborne transmission.
