Research suggests that using lubricants during receptive anal intercourse can increase the risk of rectal sexually transmitted infections (STIs), including HIV. A study involving nearly 900 men and women found that those who used lubricants were three times more likely to have a rectal STI.
Researchers have developed vaginal rings that can deliver therapeutic levels of two anti-HIV drugs for up to 30 days, while quick-dissolve films and almond-shaped tablets also show potential. These new formulations offer an alternative to daily microbicide gels and could provide a safer and more effective way to prevent HIV transmission.
New research highlights the risk of drug resistance if routine ARV screening is not done, particularly in people unknowingly infected. Studies suggest that incorporating regular testing and monitoring can mitigate this risk, emphasizing the importance of routine HIV testing in any prevention program using ARVs.
A new study has found that pregnancy doubles the risk of HIV transmission to men, with their risk increasing by double if their partner is both HIV-infected and pregnant. Researchers have also tested a vaginal microbicide in pregnant women, finding that it shows promise for preventing HIV transmission.
Researchers tested a vaginal microbicide gel containing an integrase inhibitor and found it provided significant protection against infection with a virus similar to HIV. The study showed promise for further evaluation of integrase inhibitors as a potential method for preventing HIV transmission in uninfected individuals.
