A vector in the context of infectious diseases is an organism, typically an arthropod like a mosquito or tick, that transmits a pathogen from one host to another.
AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV). HIV is primarily transmitted through direct contact with infected bodily fluids, such as blood, semen, vaginal fluids, and breast milk. It is not transmitted through insect bites or other vectors.
