The test papers for AIDS, whether domestically produced or imported, have an accuracy rate exceeding 90%, with some even reaching 95% to 97% or more. As for the accuracy of these results, the key depends on two factors: first, whether the testing method you use is accurate, and second, whether the testing is conducted after the window period has passed.

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.

How long does the fever last in AIDS?

People with AIDS are more prone to developing fever. During the onset of AIDS, it is common for the fever to last for over a month, with weight loss exceeding 10 kilograms, along with symptoms such as swollen lymph nodes throughout the body, rash, cough, sore throat, and fever. The fever in AIDS patients is mostly caused by opportunistic infections, typically involving viruses, bacteria, and fungi. The treatment of fever in AIDS should be tailored to the specific circumstances, requiring antiretroviral therapy for HIV and treatment targeting the opportunistic infections.

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.

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.

Is AIDS a sexually transmitted disease?

AIDS is caused by the infection of the Human Immunodeficiency Virus, also known as HIV, which leads to significant immune deficiency characterized by the disease. The main route of transmission is through sexual contact. It spreads quickly and has a relatively high mortality rate. Currently, there is no effective cure, making it one of the major lethal infectious sexually transmitted diseases in humans.
