Bettertoleratedfirst-lineoptionsthatincludedolutegravir,forexample,arebeingconsidered.Newstrategies, such as long-acting formulations of antiretrovirals (ARVs), are also needed forsomepatients,e.g.toimproveadherence.Itisanticipatedthattheneedforsecond-lineARTwilldiminishasintegraseinhibitorsaremorewidelyusedinfirst-lineregimensbecauseitisbelievedthatvirological failurewillbe lesscommonwiththeseARVs(9).Combinationsofprotease inhibitors and integrase inhibitorsmay provide nucleoside reverse transcriptaseinhibitor(NRTI)-sparingoptionsandbeeffectiveinthepresenceofresistancetoNRTIs.Thepotentialofmobilehealth(mHealth)isbeingharnessedtoenhancetreatmentsuccessbyprovidingHIVeducationandrealtimemonitoring,supportingadherence,andreducingtheneedforclinicvisits(10).ViralSuppressionIn2015,45%ofPLHIVinsub-SaharanAfricaonARThadachievedviralsuppression,butthisfigure was only 12% in western and central Africa.

PopulationhealthassessmentsandcountryresponsesPopulation-based HIV impact assessments (PHIA) have been carried out in Malawi,Zimbabwe,andZambiausingcommonmethodologiessothattheresultscanbecomparedand combined to increase the power of the analyses (14). The three countries aregeographically contiguous, have similar population size, and are experiencing generalizedcladeCHIVepidemics. Theprimaryobjectivesof thePHIAwere toestimatenationalHIVincidenceratesandsub-nationalprevalenceofVLsuppressioninadults.Inallcountries,thesurveyresponseratewasloweramongmenthanwomen,butmenwhohad agreed tobe interviewedwere just aswilling to undergoHIV testing aswomen.HIVprevalence in women was higher than in men in the three countries (Figure 2)5. HIVprevalenceinchildrenofbothgenderswassimilar inMalawi,butslightlyhigherformalesthanforfemalesinZambiaandZimbabwe.

ThePHIAdatahavebeenutilisedinNationalAIDSStrategiesandtodevelopHIVpoliciesandprogrammes(15).Continuedinvestmentinhealthsystemsisnecessarytoconsolidateandmaintain thehealth gains alreadyachieved.Given the stabilizationandeven reductionofdonor funding for HIV in recent years, it is essential that domestic funding for HIVprogrammesinsub-SaharanAfricaincreases(16).

There is a window of opportunitybetween 2017 and 2020 to dramatically reduce newHIV infections, but thiswill only beachievedifFast-Tracktactics,asrecommendedbyUNAIDS,areadopted(17).Meetingtheneedsofkeypopulations6KeypopulationsareatparticularriskofHIVinfectionIn2015,keypopulationsinsub-SaharanAfricaaccountedfor20%ofnewadultHIVinfections,demonstratingthatthereareconcentratedkeypopulationepidemicswithinthecontextofgeneralised epidemics driven by heterosexual transmission (18). Key populations are at amuchgreater(10-49times)riskofbecominginfectedwithHIVthanthegeneralpopulation(19).KeypopulationsathighestriskofHIVexposureinclude:menwhohavesexwithmen(MSM),peoplewho injectdrugs (PWID), sexworkers (SW), transgenderpeople,migrants,prisoners, and their sexual partners. Young women in southern Africa, who are also atextremelyhighriskofHIVexposure,areaddressedlaterinthisreport.HIVprevalenceamongMSM is rising, both globally and in sub-SaharanAfrica.HIVprevalence in SW in southernAfricais10-20timeshigherthaninthegeneralpopulation(18).InMalawi,HIVprevalenceratesinfemaleSWsandMSMwere69%and18.2%,respectively,comparedto9.1%inthegeneraladultpopulation(2016data).LevelsofknowledgeofHIVstatusandlinkagetocareareverylowinMSM.HIV-relateddeathshavetripledsince2000inadolescents,withAIDSnowthesecondcauseofdeath inthisagegroupglobally(18).HIVprevalence in prisoners in sub-Saharan Africa ranges from 2.3% to 34.9%, levels that arealmostalwayshigherthaninthegeneralpopulation.Data on HIV prevalence in transgender populations in Africa are limited, but high HIVprevalence has been reported inAsia, e.g.19.3% in Kuala Lumpur,Malaysia and 30.8% inJakarta,Indonesia(19).TransgenderwomenareatparticularriskofHIVinfectioniftheyhavemultiple sexual partners, unprotected anal intercourse, experience depression, undergounsafe hormone and silicone injections, sell sex, or take drugs before sex (20). Stigma,discrimination, and lack of legal recognition of transgender people aremajor barriers toaccessing healthcare and prevention services. This marginalisation also increases thelikelihoodofriskybehaviour.

Despitetheconsiderableneedsofkeypopulations,theiraccesstoHIVservicestendstobeinadequate or non-existent,which itmakes it very challenging to halt epidemics in thesepopulations(18).Criminalisation,stigmatisation,discrimination,andthelackofappropriateservicesarealldriversofHIVtransmissioninkeypopulations.HowcankeypopulationsbeprotectedfromHIVinfection?ImprovingHIVliteracyinallkeypopulationsisanimportantfactorinprotectingthemfromHIVinfection(18).Youngmembersofkeypopulationsareatparticularlyhighriskofinfectionandneedtailoredinformationthataddressestheirquestions.Many barriers toHIV prevention services exist. In prisons, for example, there is a lack ofcontinuity of care between different prisons and between prisons and the community.Overcrowding inAfricanprisons, highHIVprevalence, and criminalisationof sexbetweenmenpreventingcondomprovisiontoprisoners,allfacilitateHIVtransmissioninthissetting.HarmreductionprogrammesforPWIDsarenon-existent,orverylimited,inmostsub-Saharancountries.Provisionofopioidsubstitutiontherapy(OST)andneedle-syringeprogrammesisminimalinthisregionandthisincreasestheriskofHIVtransmissionbetweenPWIDsandtheirsexualpartners.InCanada,whereharmreductionandtreatment-as-preventionprogrammeshave been implemented for PWID living with HIV, PWIDs have experienced substantialdeclines inHIV incidence.Politicalwillandaccesstoresourcesareessential to implementthese prevention initiatives. Criminalisation and stigmatisation of both sex work and sexbetweenmenarecommoninsub-SaharanAfrica,whichseverelyrestrictsaccesstosexuallytransmittedinfection(STI)treatment,condoms,andmedicalcare.Innovative treatment and prevention programmes, as well as outreach testing, are allessential toreachkeypopulationsandtopreventtheepidemicbeingdrivenunderground(18).Overcomingmultipletypesofstigma(external,internalised,andanticipatedstigma)ischallenging, but it is essential if key populations are to access HIV services.

ComprehensivepackagesofHIVservicesthatareappropriatefortransgenderpeoplecanbedevelopedandhavebeenshowntobeeffective(20).Addressingstigmaandensuringthatsupportive legislation, policies, and financial arrangements are in place are essential forsuccessful service delivery. Community empowerment and addressing violence againstpeoplefromkeypopulationsarealsokeyfactors.Manytransgenderpeopleprioritiseuseofhormone therapy over HIV treatment. It is therefore considered essential for healthcareprofessionals to be aware of potential drug-drug interactions and manage patientsappropriately.Harm reduction programmes are starting in some sub-Saharan African countries, such asSouthAfricaandKenya.However, there is limitedpoliticaland financial support for theseprogrammes,despiteevidenceoftheireffectivenessinreducingtheriskofHIVinfectioninPWID(18).OSTandneedle-syringeprogrammeswereintroducedinMauritiusin2006,whenPWIDaccountedfor92%ofnewHIVinfections.In2011,OSTwasextendedtoprisons.Whenanewgovernmentwaselectedin2014,theharmreductionprogrammeswerediscontinuedand,forthefirsttimeinadecade,HIVincidenceincreasedinPWIDfrom31%in2014to35%in 2015. This demonstrates that HIV epidemics can only be controlled by ongoing andsustainedHIVprogrammesforkeypopulations.Decriminalisingsexwork,eliminatingsexualviolence,and increasingARTcoverageamongSWsinKenyawouldsubstantiallyreduceHIV incidenceamongbothfemaleSWsandtheirclients(18).SouthAfricahaspromisedtosupplyPrEPfor3,000SWs,usingmobileunitstosupplyitandotherHIV,TB,andSTIservicesincommunities,inanattempttoprotectthemandtheirclients.HealthcareprofessionalsarebeingtrainedtonotdiscriminateagainstSWsandtobesensitivetotheirneeds.Linkagetocarereached57%in2015.HIVservices(diagnosis,treatment,andmonitoring)forpeopleatriskofimprisonmentandthosealreadyinprisonsarestartingtodevelopinanumberofsub-SaharanAfricancountries(18). The aim is to provide care both inside andoutside of the prison environment. Peereducation and provision of condoms have been introduced in some prisons. Despite thepotentialofPrEPandpostexposureprophylaxis (PEP) toprotectprisoners from infection,accesstotheseinterventionsisalmostnon-existent.

There is a high level of interest in PrEP amongMSM in South Africa and demonstrationprojectshaveyieldedencouragingdataaboutacceptabilityandadherence(18).Linkagetocare,however,hasbeenlow,evenincitieswithhighqualityandaccessibleHIVservices.Reaching the ‘last 10%’ will require innovative, creative, and dispersed HIV services thatengagewith keypopulations and gobeyondhealthcare. Serviceshave tobe confidential,appropriate,efficient,relevant,andclientcentred.TestingandtreatmentofmenIntroductionHIVtestingandtreatmentofmenhashistoricallylaggedbehindthatofwomen.NumerousbarriersthatpreventmenfromaccessingHIVserviceshavebeenidentified,withstigmabeingamajorfactor.Thereisaclearneedformen-friendly,easily-accessibleclinicswithflexibleopeningtimessothatmencanaccessthemwithoutlosingpaidworkand/orincurringhightransportationcosts.Innovativetestingoptionsareneededformen–potentialofself-testingSelf-testingisattractivetomenbecauseofitsconfidentialityandflexibility(4).Theyfinditmore acceptable to self-test in the privacy of their own homes than risking stigmatisingencounters at clinics orworkplace testing sites. Self-testing can also be used to promotecouplestesting(3,4).Sofar, thesehasbeennoevidenceofan increasedriskofpotentialadverseeffectsof self-testing, suchas intimatepartner violence,homicide,or suicide (3).Linkage to care, once diagnosed, is 42-56%. A small proportion of respondents (3%,287/10,007)inastudyconductedinMalawireportedthattheyhadbeen‘forcedtotest’bytheirpartner,but94%oftheseindividualsalsosaidthattheywouldrecommendself-testingtotheirfriendsandrelatives.TreatmentofmenlivingwithHIVInvolving men in HIV prevention and treatment programmes is critical to the success ofhaltingHIVtransmission(5,21).FactorsthatincreasethelikelihoodofmenparticipatinginHIVcareincludedecentralizedhealthfacilitiessothatmostpeoplecanwalktothem,routine3-6 month appointments rather than monthly clinic visits, and elimination of diagnostichurdles (CD4 cell count, VL) prior to starting therapy (Test and Treat) (5).

HIV-relatedissuesaffectingadolescentsandyoungadultsOverviewINTEREST11addressedanumberofissuesaffectingadolescentsandyoungadultslivingwithHIV, especially in resource-limited settings. This large and growing population group isheterogeneous,withdiverseneedsandexperiences.Someyoungpeopleareinschool,someareworkingformallyorinformally,andyetothersareunemployed.Someareinstablesexualpartnerships,somehavesequentialrelationships,andsomehavenon-exclusiverelationships,while others are not sexually active. Some are already parents and some are caring forsiblings, while others have no childcare responsibilities (21). This diversity underpins theimportanceofinvolvingyoungpeopleinthedesignofHIVprevention,treatment,andcareand support HIV services that are tailored for their individual needs. It highlights theimportanceofdifferentiatedcareandservicedelivery(www.differentiatedcare.org)ratherthan ‘one size fits all’(22). Addressing the determinants of stigma and discrimination,includinginternalisedstigma,iscriticaltoenhancingthehealthandwell-beingofadolescentsandyoungadultseverywhere,regardlessofHIVstatus.HIVpreventionYoungwomen(15-24years)bearadisproportionateburdenofHIVinfectioninsouthernandeasternAfrica.TheyareuptoeighttimesmorelikelytoacquireHIVthanareyoungmen;almostthree-quarters(74%)ofyoungpeopleinthisagegrouplivingwithHIVinsub-SaharanAfricaaregirlsoryoungwomen(21,23).TheUNPoliticalDeclarationonEndingAIDSsetthegoalofreducingnewinfectionsinadolescentgirlsandyoungwomento≈100,000by2020(21).AmongthemanybarriersstandinginthewayofachievingthisobjectiveissuboptimalcomprehensiveHIVknowledgeandcondomuseamongyoungsub-SaharanAfricanwomen.InruralKwaZulu-Natal,SouthAfrica,morethan30%ofpregnantwomenareunder20yearsofageandoneinfiveofthesewomenalreadyhasHIV(23).Bytheageof23years,half(50%)ofpregnantwomeninthisregionhaveHIV.Ifawoman’spartneris4ormoreyearsolderthansheis,shehasariskofacquiringHIVinfectionthat isfrom4to8timeshigherthanifherpartnerisofasimilarage.HIVinfectionstudiesamonghighschoolstudentsinruralKwaZulu-Nataldemonstratethatgirls,especiallythosewitholdersexualpartners,aremorelikelytobeHIV-positivethanboysoftheirage.Despitereportingalowfrequencyofsexualactivity,girlsandyoungwomenaremorelikelytoengageinunprotectedsexwhentheyaresexuallyactive.
