How long did it take for the FDA to test for HIV?
But simply having a compound that could work against HIV wasn’t enough. In order to make it available to the estimated millions who were infected, researchers had to be sure that it was safe and that it would indeed stop HIV in some way, even if it didn’t cure people of their infection. At the time, such tests, overseen by the FDA, took eight to 10 years.

What is the class of antiviral drugs that prevents HIV infection?
Next to be developed were the class of antiviral drugs known as protease inhibitors, which were distinctly different from the reverse transcriptase inhibitors in that they do not seek to prevent infection of a host cell, but rather to prevent an already infected cell from producing more copies of HIV.
Can you use different antiviral drugs for HIV?
On the other hand, however, combination therapies have not yet achieved the most optimistic goals set by scientists, much less the often-hyped claims of the popular media. In particular, the complete elimination, or "eradication," of HIV from an infected individual has never been achieved, and perhaps may never be achieved because HIV has the capacity to remain dormant in certain cells and also to infect difficult-to-reach cells in the central nervous system and other parts of the body. Similarly, antiviral medications have the characteristic of allowing full or partial resistance to develop after even a week of missed medication, irregular use, or incomplete doses, and cross-resistance is very common.
Does Haart help with HIV?
HAART has been prescribed by physicians in a wide variety of combinations, and , over time, convincing evidence has emerged that particular combinations of one protease inhibitor and one or two other drugs can have dramatic effects, reducing the amount of virus in the blood, prompting an increase in the number of CD4+ cells, and leading to improved health and well-being and minimizing the opportunity for new mutations which might create drug-resistant strains of HIV . By the start of 1997, combination therapy had become the standard of care for HIV-infected individuals who have begun to exhibit signs of significant immunosuppression, although no clear cut consensus has emerged about the best time to initiate therapy. This decision must be based on balancing a variety of factors including the length of time since initial infection, current CD4 cell count and viral load, clinical prognosis, side effect profile, and the individual's psychological readiness and motivation to begin and adhere to treatment.
How does HIV become resistant to drugs?
Such resistance generally occurs when a random mutation during the replication of HIV causes a small genetic change in the virus's RNA, in the process making it less vulnerable to the effects of antiviral drugs. Drug resistance can seriously complicate treatment by rendering drugs less effective or even completely ineffective. Further, once an organism has developed resistance to one drug, it can also become resistant to other drugs in the same class (cross-resistance) or to a number of different drugs (multidrug resistance).
Is AIDS a latent virus?
Thus, the onset of symptoms of AIDS is now known to be the result not of a sudden resurgence of a latent virus, but rather of a slow "war of attrition" between HIV and the host immune system, with the latter slowly being whittled away by the former.

The drug does not rid the body of the virus. Concern Over High Price.
How long does it take for azidothymidine to be approved?
The antiviral drug azidothymidine, AZT, has reached the market with remarkable speed, experts say, proceeding from test-tube experiments to patient trials to Federal approval in less than two and a half years. For most drugs, the process takes many years more. The drug has been developed as a treatment for AIDS in a collaborative effort between Burroughs Wellcome and the National Cancer Institute. 1964: Dr. Jerome P. Horwitz of the Michigan Cancer Foundation reports that AZT, a drug he had synthesized, had failed to work against cancer. Research on the drug halts. November 1984: Burroughs Wellcome scientists discover that AZT inhibits animal viruses in the test tube. February 1985: Scientists at the National Cancer Institute and elsewhere show that AZT inhibits duplication of the AIDS virus in the test tube. June 14, 1985: Burroughs Wellcome asks Food and Drug Administration for permission to test the drug on AIDS patients.

When did HIV test come out?
Finally, when the first HIV test came out in 1985, doctors and patients could know who was or was not infected. We could at least name our viral enemy. Famously, the AIDS activists Act Up proclaimed “ Silence = Death ,” the converse of which was the radical concept that speaking up about the diagnosis of HIV restored some measure of power to the powerless. On the other hand, in those days a positive test result was sometimes seen as an identity-changing death sentence. As Susan Sontag wrote in AIDS and Its Metaphors, “Fear of sexuality is the new, disease-sponsored register of the universe of fear in which everyone now lives.”
How did public health messaging and activism change the societal context of HIV testing?
Decades of public health messaging and activism have also changed the societal context of HIV testing. When the HIV epidemic was first recognized , public mention of homosexuality in particular was stigmatized, and governmental squeamishness with the issue is widely credited for exacerbating the early US AIDS epidemic.
Can HIV be tested with serosorting?
Beyond HIV treatment, another option is serosorting, in which people with a positive HIV test elect to have sex only with others with the same serostatus, thereby reducing the risk of transmission to people without HIV. This is yet another example of how HIV testing can empower people with HIV to help contain the epidemic.

Fortunately HIV tests have steadily gotten better through the years. The latest fourth generation tests can detect nearly all cases of HIV from the first few weeks of initial infection, and can do so in hours. As a result, in 2014 the CDC updated its testing guidelines recommended a new testing algorithm that uses fourth generation HIV tests.
How long does HIV test negative?
Despite sensitivity and specificity rates over 99%, early generation HIV tests still could remain falsely negative for months after initial infection. This meant newly infected patients went unconnected to lifesaving prevention and treatment opportunities and often did not know how important it was for them to alter risky behaviors that could transmit HIV?
