Which disease is NOT transmitted by mosquitoes?

Rocky Mountain spotted fever is primarily transmitted through ticks, specifically the bite of infected Dermacentor variabilis (the American dog tick) or Dermacentor andersoni (the Rocky Mountain wood tick). This disease is characterized by symptoms such as fever, rash, and potential complications if not treated promptly.

On the other hand, dengue fever, malaria, and Zika virus are all diseases that are directly transmitted through mosquito bites. Dengue fever is caused by the dengue virus and is spread primarily by Aedes mosquitoes. Malaria is caused by Plasmodium parasites, which are transmitted through the bites of infected Anopheles mosquitoes. Zika virus, also spread by Aedes mosquitoes, can lead to various health issues, particularly in pregnant women.

Understanding the vector responsible for disease transmission is crucial in public health efforts to control and prevent these diseases. Hence, the correct identification of Rocky Mountain spotted fever as not being transmitted by mosquitoes is significant in the context of vector-borne disease prevention strategies.
