The search for a treament

Once it was known that AIDS was caused by a human retrovirus, the search for drug-treatments began. The viral enzyme reverse transcriptase, is used by retroviruses use to construct DNA from their viral RNA once they have infected a cell. Humans and other mammals do not make this enzyme, making it an obvious drug target.

How long does it take for HIV to rebound?

According to a published study, 9 of 10 people with HIV viral load levels below 100 copies/106 cells had a rebound within 12 weeks after ARV interruption. The 10th person maintained low HIV viral load level without drugs for more than 48 weeks.

Can HIV cause drug resistance?

The short answer is yes. The HIV virus very easily creates mutations. Not all these mutations lead to drug resistance, but some do. The International Aids Society publishes annually a list of mutations that defeat the action of the antiretroviral drugs that patients need to suppress the virus. New mutations enter the list every year. On the good side, there is a constant development of new formulations that become available that can be used to replace an antiretroviral that no longer works. The only way we have so far of finding out which mutations each patient has is to genotype their virus,
