New guidelines from the WHO propose the use of antiretrovirals as a form of HIV prevention

The World Health Organization (WHO) released this week the new HIV / AIDS treatment and prevention guidelines. The recommendations include that all people who have the HIV virus start antiretroviral treatment immediately and that everyone at risk of infection uses similar drugs as a precaution in addition to the condom before intercourse.

Today, PrEP is only available on some foreign websites for private purchase in Brazil. This is because the use of antiretrovirals as a form of prevention is still in the testing phase. The Ministry of Health is awaiting the results of studies conducted by universities such as the Oswaldo Cruz Foundation, the University of São Paulo, the Federal University of Bahia and the Federal University of Minas Gerais to estimate when the pre-exposure prophylaxis, or PrEP, should be available to the population. Unified Health System (SUS). Currently, HIV treatment is free through the public network, and all people who have been exposed to the virus can seek a health post within 72 hours to take post-exposure prophylaxis (PEP), which consists of using antiretrovirals over 28 days to prevent infection.

Currently, the treatment for people living with HIV consists of the combination of at least three antiretroviral drugs, which aim to suppress and stop the progression of the virus within the body. Since 2013, WHO has also recommended the use of similar drugs for prevention purposes, but rather the recommendation was exclusively for homosexuals, men who have sex with men, sex workers and people with infected partners. Now, with the new guidelines, millions of people around the world are recommended to take preventive doses as well.

It is important to note that, although revolutionary, this new form of prevention does not replace condom use, since does not fully prevent the virus and is not effective against other sexually transmitted diseases (STDs).
