Which diseases are transmitted by Culex nigripalpus and Culex quinquefasciatus?

Culex nigripalpus and Culex quinquefasciatus are both mosquitoes that serve as important vectors in the transmission of several diseases. The correct answer points to Eastern Equine Encephalitis (EEE), St. Louis Encephalitis, and West Nile virus as diseases transmitted by these species.

Eastern Equine Encephalitis is a potentially severe viral disease affecting the central nervous system of horses and humans, with Culex nigripalpus being a significant vector in the southeastern United States. St. Louis Encephalitis is another viral disease transmitted by these mosquitoes, also affecting the central nervous system and known for causing encephalitis outbreaks. Additionally, West Nile virus, which can lead to serious neurological disease, is transmitted by both Culex species, with Culex quinquefasciatus being particularly recognized for its role in urban environments.

The other options mention diseases that are not primarily associated with Culex nigripalpus and Culex quinquefasciatus. For instance, malaria is primarily transmitted by Anopheles mosquitoes, while chikungunya and dengue fever are transmitted mainly by Aedes species. Yellow fever transmission is also attributed to Aedes mosquitoes rather than
