Itching in the armpits and groin area is not an infection with AIDS. AIDS is an infectious disease caused by human immunodeficiency virus infection, which generally does not have typical clinical manifestations, but mainly manifests as a decrease in body resistance, thus easily inducing many infectious diseases such as malignant tumors. The itching in the armpits and groin area may be due to eczema caused by local dampness and excessive sweating, or it may be a bacterial or fungal infection. If you have a rash, you need to make a clear diagnosis based on the rash, and if necessary, you can also perform fungal microscopy to help make a clear diagnosis. Pay attention to showering regularly, wear loose and comfortable clothing, avoid dampness and sweating in the armpits and groin, which may lead to a rash.
