In the face of AIDS, human insist on science for answers, methods. After mastering more scientific knowledge and prevention laws, researchers reached a consensus: AIDS can be prevented and controlled. The strategy is in each of our hands: "Detection should be done, treatment should be done, early detection and early treatment".

There is a window period of detection, that is, a period of time from the time the virus infects the human body to the time that HIV nucleic acids, antigens or antibodies can be detected in the blood. The "window period" is just as contagious even though antibodies or viruses are not detectable. Different detection methods have different window length. The most commonly used is antibody testing, which has a window period of 4 to 12 weeks. Nucleic acid testing is the most advanced method, which can effectively shorten the window period to about one week after infection.

In general, HIV infection can be ruled out if there is no repeat of the high-risk behavior within 12 weeks of the previous high-risk behavior and no antibody is detected.

In the mid-1990s, scientists created highly effective antiretroviral therapy, or HAART, which is a combination of drugs that act on the virus at different stages of replication. Since its use in 1996, it has significantly reduced the death rate from AIDS.

Studies have confirmed that after the implementation of standardized antiviral treatment, the viral load of infected people decreased, not only their own immunity was enhanced, but also the probability of external transmission was significantly reduced.

The adjustment process of the timing of antiviral treatment in our country, from ≤200 to ≤350 CD4 cells to >350 start treatment, and finally, antiviral treatment is recommended for all HIV infected people as soon as possible. The earlier you start treatment, the more likely you are to get the best results.
