Gay men are at high risk of contracting HIV, and currently they are a high-risk group for HIV. Gay men are mainly infected with HIV through sexual contact, and the way they have sex is mainly anal sex. This situation can easily lead to the breakage of the local skin and mucous membrane, thus allowing the HIV virus to enter the body and make it easier to get infected with HIV. Some gay men have promiscuous sex or multiple sexual partners, which can also lead to the spread of HIV. Therefore, for gay men, it is generally recommended to be screened for HIV antibodies. If the HIV antibody is positive, further confirmatory testing is recommended. If you are negative for HIV, it is recommended that you wear a condom to protect yourself during future sexual intercourse.
