Which disease does NOT involve mosquitoes?

AIDS (HIV) is the correct choice because it is caused by a virus that primarily spreads through human-to-human contact, particularly through blood, sexual contact, and from mother to child during childbirth or breastfeeding. Unlike Dengue Fever, Malaria, and West Nile Virus, which are all transmitted through mosquito bites, HIV transmission does not involve an insect vector.

Dengue Fever is transmitted by Aedes mosquitoes, Malaria is spread by Anopheles mosquitoes, and West Nile Virus is primarily carried by Culex mosquitoes. Therefore, the only option that does not have an association with mosquito transmission is AIDS (HIV), making it the appropriate answer in this context.
