IRIN examines the WHO’s ongoing efforts to synthesize and communicate guidance about the risk of HIV infection and transmission for women taking injectable hormonal contraception, including a meeting scheduled for this week in Geneva. The news service looks at the history of the issue, including “a February 2012 [WHO] statement standing by current guidelines allowing women living with or at high risk of HIV to use hormonal contraception” and advising women on injectable contraception to use condoms concurrently; reaction from representatives of non-governmental organizations and WHO officials; and efforts by researchers to “formulat[e] a concept note on a clinical trial that could be the world’s first to examine whether hormonal contraception does indeed increase HIV risk” (12/5).
