One in ten new cases of HIV in gay and bisexual men are linked to gonorrhea and chlamydia infection. That’s the conclusion of a modelling study highlighted by the NCSD (National Coalition of STD Directors) in the US.
The journal, Sexually Transmitted Diseases, published the research this week. Both sexually transmitted infections can increase the risk of HIV transmission taking place: a fact known for some time.
However, with rates of both gonorrhea and chlamydia rising in the US, health experts are concerned how this may impact public health advances in tackling HIV.
Between 2013-2017, the US saw a 22% increase in chlamydia. Gonorrhea diagnosis shot up by 67%. By comparison, there has been a 13% drop in HIV diagnosis over the last eight years.
The precise extent to which chlamydia and gonorrhea increase HIV transmission is unknown. Other biological factors may also play an influence. For this reason, parts of the ‘modelling’ study relied on estimates.
However, researchers from Emory University and the Centers for Disease Control and Prevention (CDC) in Atlanta say their findings should be used by those working in public health to address the issue of STIs and HIV transmission.
