What wounds can transmit AIDS?

Many people are very scared when talking about AIDS, and even feel that even the air can transmit AIDS. This is a kind of AIDS fear caused by people's lack of understanding of AIDS. For AIDS, it is important to understand some correct methods of transmission, which will help prevent it and avoid some bad psychological conditions. Some wounds can transmit AIDS, while some wounds cannot, such as bleeding open wounds. If the AIDS virus is contaminated at this time, it may cause infection.

What wounds can transmit AIDS?

1. Bleeding open wounds

For normal skin tissue, unless it is an open wound that is bleeding, the virus generally cannot break through and cause infection. This is why we say there is no need to worry about scabbed wounds. Skin damage is different from wounds in the usual sense. For example, many people experience shedding of the skin. The skin in the shedding area is damaged. The outer layer is old/dead skin (epidermis), and the inner layer is new skin (epidermis).

But it was not a wound, no blood came out. The entire skin tissue is relatively intact, and the stratum corneum (epidermis) protects the blood vessels and capillaries under the skin from being exposed. HIV can only survive in human body fluids and only attacks lymphocytes in the human body. Therefore, wounds that do not bleed are very effective in protecting against HIV. Open bleeding wounds are different. The stratum corneum (epidermis) is incomplete, and the blood vessels or capillaries are directly exposed. There is a risk of infection when they come into contact with body fluids or blood containing viruses.

2. Mucosal tissue

For the mucosal tissues in the human body's cavity openings (urethral opening, nasal cavity, oral cavity, eyes, etc.), the mucosal wall is very thin compared to the skin, because there is no stratum corneum (epidermis) in the mucosal area. Once there is damage, even if you can't see blood flowing out, it has already created an entry point for the virus to invade.

If classified by degree of danger, it can be summarized into the following three types: a. The skin is damaged (epidermis is damaged or stratum corneum is damaged), the skin mucosa (dermis) is exposed, but there is no bleeding --> no danger. (Scabbing on the wound also falls into this category and is not dangerous) b. The skin is broken and bleeding (both the epidermis and dermis (skin and mucous membranes) are broken) --> There is a small risk of infection. Please go for testing after 6 weeks. c. If the mucous membrane is damaged (oral cavity, urethral opening, etc.), with or without bleeding --> there is a small risk of infection. Please go for testing after 6 weeks.
