A new UNAIDS report warns that declines in new HIV infections among adults have slowed, threatening progress toward ending the AIDS epidemic. The Prevention Gap Report shows that the annual number of new HIV infections among adults has stalled at about 1.9 million and new infections among adults are rising in some regions. The report identifies global gaps in HIV prevention services and declines in donor funding. It also documents trends in the epidemic and progress and gaps in HIV prevention by region, providing chapters on each region and on key interventions, including voluntary medical male circumcision (VMMC). To get back on track to reducing new HIV infections to 500,000 by 2020, UNAIDS recommends continued progress toward the 90-90-90 HIV testing and treatment targets and intensive focus on delivering five prevention “pillars” (including VMMC) comprehensively and in combination.
