The HIV latent period is the process from HIV infection to the onset of AIDS without antiretroviral drug treatment, when HIV can be detected by a blood test. Therefore, if you suspect that you are infected with HIV, you can go to a regular hospital for a blood test to clarify the existence of your infection through HIV antibodies. Since HIV has a long incubation period in the human body and patients do not show obvious symptoms at the beginning of the infection, checking the blood for HIV antibodies is one of the best ways to determine the infection and evaluate the extent of HIV transmission. Therefore, people who have high-risk sexual behavior, occupational exposure, and importation of unknown blood should be tested regularly for HIV. If a blood test is performed and the test results indicate a positive HIV antibody, a retest is usually recommended, and if the second test results still indicate a positive HIV antibody, AIDS can be diagnosed. 80% of HIV-infected patients can detect antibodies in the initial screening test 6 weeks after infection, and almost 100% of infected patients can detect antibodies after 12 weeks. Only a very small number of patients have antibodies detected after 6 months of infection. At this stage, the main treatment for AIDS is highly effective antiretroviral therapy, also known as cocktail therapy, often combined with tenofovir, lamivudine, nevirapine, efavirenz, and zidovudine, which can effectively strengthen the patient’s immunity and reduce the infectiousness of the virus. In addition, if AIDS is diagnosed, on the one hand, we need to pay attention to the lifestyle to avoid infecting others, and on the other hand, we recommend active treatment. Although there is no specific drug treatment for AIDS, early detection and treatment can effectively control the spread of the virus, improve the quality of life and prolong the survival cycle.
