Semen-contact wounds from AIDS patients are high-risk exposures and carry a high risk of infection.
The source of HIV infection is human immunodeficiency virus (HIV) infected people and AIDS patients, mainly through sexual transmission, blood transmission and vertical transmission from mother to child.
HIV is present in the blood, semen, and vaginal secretions of infected individuals, and the viral content of semen is about 1 to 10 million individuals/mL, much higher than vaginal secretions, so wound exposure to semen from AIDS patients carries a high risk of infection.
According to the viral kinetics of HIV, after entering the human body, HIV generally reaches the local lymph nodes within 24~48 hours, and the viral components can be detected in the peripheral blood in about 5 days, followed by viremia, which leads to an acute infection characterized by a short-term transient and rapid decrease in the number of CD4+ T lymphocytes.
Therefore, once a broken wound comes into contact with the semen of an AIDS patient, it is necessary to go to the CDC at the first opportunity and take anti-blocking drugs, the sooner the better, in order to block the virus from entering the bloodstream and inducing systemic spread of infection.
