  abstract = {{O}bjectives: {T}o estimate the epidemiological impact of past {HIV} interventions and the magnitude and contribution of undiagnosed {HIV} among different risk groups on new {HIV} acquisitions in {C}ote d'{I}voire, {M}ali and {S}enegal. {D}esign: {HIV} transmission dynamic models among the overall population and key populations [female sex workers ({FSW}), their clients, and {MSM}]. {M}ethods: {M}odels were independently parameterized and calibrated for each set of country-specific demographic, behavioural, and epidemiological data. {W}e estimated the fraction of new {HIV} infections over 2012-2021 averted by condom use and antiretroviral therapy ({ART}) uptake among key populations and non-key populations, the direct and indirect contribution of specific groups to new infections [transmission population-attributable fraction (t{PAF})] over 2012-2021 due to prevention gaps, and the distribution of undiagnosed people with {HIV} ({PWH}) by risk group in {J}anuary 2022 and their t{PAF} over 2022-2031. {R}esults: {C}ondom use and {ART} may have averted 81-88% of new {HIV} infections over 2012-2021 across countries, mostly due to condom use by key population. {T}he t{PAF} of all key populations combined over 2012-2021 varied between 27% ({C} & ocirc;te d'{I}voire) and 79% ({S}enegal). {M}ale key populations (clients of {FSW} and {MSM}) contributed most to new infections (>60% in {M}ali and {S}enegal) owing to their higher {HIV} prevalence and larger prevention gaps. {I}n 2022, men represented 56% of all {PWH} with an undiagnosed infection in {C}ote d'{I}voire (male key populations = 15%), 46% in {M}ali (male key populations = 23%), and 69% in {S}enegal (male key populations = 55%). {I}f {HIV} testing and {ART} initiation rates remain at current levels, 20% of new {HIV} infections could be due to undiagnosed key populations living with {HIV} in {C} & ocirc;te d'{I}voire over 2022-2031, 53% in {M}ali, and 65% in {S}enegal. {C}onclusion: {S}ubstantial {HIV} diagnosis gaps remain in {W}estern {A}frica, especially among male key populations. {A}ddressing these gaps is key to impacting the {HIV} epidemics in the region and achieving the goal of ending {AIDS} by 2030.},
