If the skin is intact, generally, contact with the blood of an HIV-infected person will not transmit the virus. However, if the skin is damaged and comes into contact with the blood of an HIV-infected person, there is a possibility of transmission. Additionally, the mucous membranes of the body, such as in the eyes, inside the mouth, and various cavities, can potentially get infected with HIV if they come into contact with HIV-infected blood. If these mucous membranes are damaged, the risk of HIV infection significantly increases.

How long does it take to detect HIV?

Actually, the diagnosis of AIDS is mainly through the testing of AIDS antibodies or AIDS nucleic acids, and the antibody test for AIDS needs to be conducted after the window period. Generally, the window period for AIDS is about four weeks, and the test for AIDS antibodies or AIDS nucleic acids should be conducted after four weeks. If the result is positive, then it can be diagnosed. Further confirmation experiments at the disease control center are needed if the AIDS confirmation test is positive to diagnose AIDS. Once diagnosed with AIDS, treatment against the AIDS virus is required.

Which test determines AIDS?

To confirm AIDS infection, initial screening is conducted for HIV antibodies. If the result is positive, further confirmatory tests must be performed at a disease control center. Only if the confirmatory tests are positive can a diagnosis of AIDS be made. Therefore, confirmatory tests are essential to determine the presence of HIV infection. Once an HIV infection is confirmed, it is crucial to start timely and scientifically sound antiretroviral therapy, as well as to ensure proper rest and maintain good health.

AIDS is divided into four stages.

AIDS clinical stages are divided into four phases: acute infection phase, asymptomatic infection phase, AIDS prodrome, and AIDS phase. The acute infection phase refers to the period after a person is infected with HIV, where symptoms similar to a common cold can appear after half a month, and the symptoms generally disappear after a month. Two months later, HIV antibodies can be detected through blood tests. After this, the person enters the asymptomatic infection phase, which on average can last for 7-8 years, and in some cases, up to about 10 years, followed by the AIDS prodrome, and the final phase is the AIDS phase.

How long does it take for AIDS to manifest?

After the human body becomes infected with the HIV virus, 50%-70% of people may exhibit symptoms similar to the common cold, such as fever, headache, sore throat, and muscle and joint pain, about two weeks later. There can also be generalized swelling of the lymph nodes, the appearance of maculopapular rashes, and symptoms such as nausea, vomiting, and diarrhea. Generally, these symptoms will disappear after about a month, and then a symptom-free infection period follows, which can last from 1 to 10 years. Subsequently, the individual enters the AIDS phase. During the AIDS phase, various types of infections erupt, including bacterial, viral, fungal, and parasitic infections, and even concurrent malignant tumors, all of which can lead to death.

What are the symptoms of AIDS?

The primary symptoms of AIDS are mainly due to immunodeficiency and opportunistic infections caused by a weakened immune system. During the acute phase of AIDS, the virus replicates in large numbers, leading to immune damage and disorder. In the acute phase, symptoms such as rashes, fever, sore throat, weight loss, and diarrhea are common. During the symptomatic phase, symptoms like unexplained fever, diarrhea, chest tightness, coughing, phlegm, and numerous white secretions on the oral tongue are commonly observed.
