On November 7, 2002, the FDA approved the OraQuick test as the first rapid HIV test, providing results in as little as 20 minutes using whole-blood specimens obtained from a fingerstick or venipuncture. Prior to this approval, HIV tests required blood samples to be sent to a laboratory, resulting in longer wait times for results.
The National HIV Testing Day on June 27 is organized annually by the U.S. Department of Health and Human Service's AIDS.GOV program [8] and the Centers for Disease Control and Prevention’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention [9] Walgreens is one corporate sponsor, and offers free HIV testing on that day at a number of its drugstore locations (140 cities in ...
The window period for HIV may be up to three months, depending on the test method and other factors. RNA based HIV tests has the lowest window period. Modern and accurate testing abilities can cut this period to 25 days, 16 days, or even as low as 12 days, again, depending on the type of test and the quality of its administration and interpretation.
Education is recognized as a social determinant of health. [1] [2] Education has also been identified as a social vaccine against contracting HIV. [3]Research suggests a negative linear relationship between educational attainment (years of education) and HIV infection rate, especially the educational attainment of women and girls.
The eclipse period is a variable period starting from HIV exposure in which no existing test can detect HIV. The median duration of the eclipse period in one study was 11.5 days. The window period is the time between HIV exposure and when an antibody or antigen test can detect HIV. The median window period for antibody/antigen testing is 18 days.
Each month, about 1,200 actors were tested for HIV, with results as early as 14 days after infection. This test is effective 10 days after potential infection, and anytime thereafter (HIV-1 DNA, by PCR) as compared to the alternative HIV test which requires a six-month waiting period to be effective.

SARS-CoV-2 and HIV-1 have similarities—notably both are RNA viruses—but there are important differences. As a retrovirus, HIV-1 can insert a copy of its RNA genome into the host's DNA, making total eradication more difficult. [156] The virus is also highly mutable making it a challenge for the adaptive immune system to develop a response.
Thus HIV infection can only be diagnosed by PCR testing for HIV RNA or DNA, or via testing for the p24 antigen. [30] Much of the world lacks access to reliable PCR testing, and people in many places simply wait until either symptoms develop or the child is old enough for accurate antibody testing. [113]
