BACKGROUND
• IdenBfyingindividualswithunrecognizedHIVinfecBoncriBcaltodeployingHIVtesBng,prevenBon,andsurveillanceresources.

• ComparedtoMSMwhoself-reportedHIV+statusandARVuse,MSMmisreportersin2011and2014weremorecommonlynon-HispanicBlack,hadlesseducaBon,lowestincome,bisexual,andmorebingedrinking.MSMmisreportersin2014alsowereolder,morecommonlyhomeless,andreportednon-injecBonheroinorcocaineuse.
• AmongPWID,misreportershadlowereducaBonandemploymentandincreasedbingedrinking.
• RecalculatedprevalenceofunrecognizedHIVinfecBonamongHIV+MSMwas34.3%in2011andsubstanBallyreducedto15.7%in2014.RecalculatedprevalenceofunrecognizedHIVinfecBonamongHIV+PWIDwas11.4%.
