Mosquitoes are responsible for all except?

Mosquitoes are known vectors for a number of diseases, as they can transfer pathogens from one host to another. The diseases attributed to mosquitoes include malaria, which is caused by the Plasmodium parasite and transmitted primarily by Anopheles mosquitoes, as well as encephalitis, which can be caused by various viruses like West Nile virus or Eastern equine encephalitis, that are transmitted by different species of mosquitoes. Yellow fever is another viral disease transmitted by mosquito bites, particularly by the Aedes aegypti mosquito.

Q fever, on the other hand, is primarily caused by the bacterium Coxiella burnetii and is not transmitted by mosquitoes. Instead, it is mainly spread through inhalation of contaminated aerosols or contact with infected animals, particularly livestock, and their products. This fundamentally distinguishes Q fever from the other diseases listed, which are all vector-borne and specifically transmitted by mosquito species.
