What is the late stage CD4 count for AIDS?
Generally speaking, in individuals infected with HIV, if the CD4 count falls below 200, it progresses to the AIDS phase. If the CD4 count falls below 50, it indicates the late stage of AIDS, during which the body's immune function is severely compromised. This makes it easy to contract various opportunistic infections, opportunistic tumors, as well as AIDS-related inflammatory syndrome, wasting syndrome, etc. Once AIDS is definitively diagnosed, it is necessary to start timely and scientifically sound anti-HIV treatments as soon as possible.
What are the symptoms of AIDS?
During different stages of HIV infection, there are some varying clinical symptoms. The latency period of HIV, also known as the asymptomatic period, generally has no obvious symptoms, though some individuals may only show enlargement of lymph nodes. During the acute infection stage of HIV, symptoms such as generalized lymph node enlargement, fever, rash, and cough are common. In the late stages of HIV, due to severe deficiencies in immune function, there is a high susceptibility to a variety of opportunistic infections, which can lead to unexplained spontaneous fever, diarrhea, cough, and other symptoms that must be addressed according to the specific circumstances.
When does AIDS occur?
About half a month after being initially infected with HIV, 50%-70% of people will experience symptoms similar to those of a cold, including headache, fever, sore throat, pain in muscles and joints, nausea, vomiting, diarrhea, swelling of lymph nodes throughout the body, or the appearance of maculopapular rashes on the skin. These symptoms will all disappear within about a month, after which the individual will enter a latent period that generally lasts from 1 to 10 years, before progressing to the AIDS phase. Once in the AIDS phase, various symptoms can occur at any time throughout the body.
What is the difference between HIV infection and AIDS?
There is a significant difference between HIV infection and AIDS. HIV infection refers to a person being infected with the HIV virus, but not yet reaching the stage of illness. At this time, the body's immune system is generally still normal, there are no other discomforts, and no opportunistic infections have occurred. This refers to HIV infection. AIDS, however, usually denotes the stage of illness onset, commonly featuring some opportunistic infections or opportunistic tumors, with many symptoms appearing. By testing CD4 cells, a diagnosis of AIDS is often made when CD4 cell counts are generally below two hundred.
Is a white coating on the tongue AIDS?
Actually, a white coating on the tongue is not directly related to HIV. In most cases, a white tongue is considered likely due to indigestion, or possibly due to inflammation in the mouth, and there's generally no need to worry too much. If you are concerned about HIV infection, you need to go to a hospital for further testing of HIV antibodies to rule it out. It is advised to rest more, avoid spicy and stimulating foods in your diet, refrain from unclean sexual activities, and avoid frequent sexual activities. This can effectively improve some symptoms and prevent the occurrence of HIV/AIDS.
How to prevent AIDS
The HIV virus primarily exists in the blood, semen, vaginal secretions, pleural fluid, cerebrospinal fluid, and breast milk of people with AIDS. It is mainly transmitted through sexual contact, including homosexual, heterosexual, and bisexual contact, as well as through blood and blood products. This includes intravenous drug injection, invasive medical procedures, and tattooing. There is also mother-to-child transmission, mainly through the placenta during childbirth and breastfeeding. To prevent AIDS, one must avoid the aforementioned behaviors. Everyday actions such as handshakes, hugs, and social kisses, as well as normal daily contact, do not transmit the HIV virus.
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.
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.
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.
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.
