Introduction
Under normal circumstances, the HIV virus exists in semen and vaginal secretions, and is transmitted through sexual contact that causes mucosal damage. The HIV virus is present in the bodily fluids, such as semen and vaginal secretions, of infected individuals. During sexual activity, close contact and friction occur between the genital areas of both partners. Such friction may cause minor damage to the mucous membranes of the genital organs or mouth.
Under normal circumstances, the HIV virus exists in semen and vaginal secretions, and is transmitted through sexual contact that causes mucosal damage. The specific process is as follows:
HIV exists in the bodily fluids of infected individuals, such as semen and vaginal secretions. During sexual activity, close contact and friction occur between the genital areas of both partners. This friction may cause minor injuries or breaks in the mucous membranes of the genitals or mouth, allowing the virus present in semen or vaginal secretions, which contain high quantities of HIV, to enter the partner's bloodstream, thereby causing infection.
For males, during ejaculation, large amounts of HIV in the semen are released into the partner's body. If the partner's genitalia or mucous membranes are damaged, the virus can then enter their system. For females, vaginal secretions also contain the virus, which can similarly be transmitted to the sexual partner through mucosal damage during sexual activity.
When engaging in sexual activity, it is important to use a condom of reliable quality to prevent HIV infection and other sexually transmitted diseases.
