After the HIV virus enters the human body, it reproduces and replicates in the blood system, then attacks the human immune system, causing a severe deficiency in immune function, leading to a decrease in the body's resistance. When the immune system is weakened, it will be accompanied by invasions of various pathogens and even the occurrence of various malignant tumors.

Does blistering at the base of the tongue indicate AIDS?

It is unscientific and inaccurate to judge whether someone has HIV solely based on bubbles at the base of the tongue. To correctly determine if someone has HIV, we need to consider the medical history, whether there has been exposure to the HIV virus, whether screening tests have been conducted, and whether confirmatory tests have been carried out. Only by considering these factors can we accurately determine whether someone has HIV.

AIDS is a type of disease.

AIDS is primarily caused by infection with the HIV virus, which then proliferates massively in the body. The HIV virus destroys the human immune system, leading to a significant decline in the CD4T lymphocyte system and immune function. After the loss of immune function, a series of opportunistic infections and opportunistic tumors can occur. Therefore, AIDS is actually an acquired immunodeficiency disease, mainly transmitted through sexual contact, as well as mother-to-child transmission and blood transmission.

Can tattoos transmit AIDS?

Indeed, tattooing is a risk factor for HIV infection, especially in informal institutions where tattoo equipment may be shared. If the tattooing equipment is not properly sterilized, there is a risk of HIV infection. Tattooing and other forms of needle injuries are also pathways for HIV transmission. However, the most common route of HIV transmission is through sexual transmission, often via unprotected sexual activities. There are also cases of mother-to-child transmission, which should be considered based on specific circumstances.

Routes of HIV transmission

According to epidemiological surveys of AIDS, the main mode of transmission is actually through sexual contact, which accounts for 90% of all transmission methods. Besides sexual transmission, it can also spread through blood transmission and mother-to-child transmission. Blood transmission mainly refers to needle stick injuries, intravenous drug use, and there are also risks involved with eyebrow tattooing, ear piercing, and tattooing. If pregnant women with AIDS do not receive proper intervention, the virus can easily be transmitted to the newborn, and this is the concept of mother-to-child transmission.

How to test for AIDS?

If you suspect you might have HIV for various reasons, or if you have had high-risk sexual behaviors, we generally recommend that patients go to a formal hospital and have a blood test for HIV screening. It's usually best to get tested between 1 and 2 months after potential exposure. If the test is negative, HIV can generally be ruled out. If the sexual behavior was high-risk, then another test can be conducted at the end of the third month. If there is frequent high-risk sexual activity, then another follow-up test can be done at six months. If all tests are negative, HIV can be ruled out. If a test is positive, further confirmatory tests should be done at a disease control center.
