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.

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.

How did AIDS originate?

AIDS is primarily contracted through sexual transmission, blood transmission, and mother-to-child transmission. After infection with the HIV virus, it destroys the body's immune function and invades the immune system, leading to a severe decline and defects in immune function. As a result, a series of opportunistic infections and opportunistic tumors may occur. Once AIDS is definitively diagnosed, it requires scientific and reasonable comprehensive treatment including antiretroviral therapy.

Is herpes zoster AIDS?

Dyshidrosis belongs to a type of allergic disease and is categorized under eczema, commonly occurring on both hands. This condition has a high incidence rate and has no relation to HIV/AIDS. HIV/AIDS, caused by sexual contact or blood transmission, leads to Acquired Immunodeficiency Syndrome and is distinctly different from dyshidrosis. Dyshidrosis can be completely cured through conventional anti-allergy treatments or by applying topical steroid creams. On the other hand, once infected with HIV/AIDS, treatment can be complicated, requiring long-term medication to suppress viral replication, but it cannot be completely cured. Dyshidrosis is not related to HIV/AIDS, nor is it a preliminary symptom of HIV/AIDS; there is no connection between the two.

initial symptoms of AIDS

People infected with HIV may experience a series of symptoms in the early stages of the disease, about two to three weeks after being infected with the virus. At this time, due to the virus's rapid growth and reproduction in the body, symptoms such as viral viremia can occur, including rash, fever, sore throat, and swelling of lymph nodes throughout the body. These symptoms are reversible and can subside after one to two weeks. Many people infected with HIV may not show any symptoms. The diagnosis of HIV is mainly confirmed through tests such as HIV antibodies, and it is not possible to infer HIV infection based merely on external symptoms.

Can AIDS be ruled out after six weeks?

Going to the hospital for HIV screening after six weeks is entirely feasible, as it typically surpasses the window period. However, if you have engaged in high-risk behaviors, we recommend that you get tested again after three months. If there are frequent high-risk behaviors, we advise you to undergo another test at six months to thoroughly rule out HIV.
