  abstract = {{O}bjective {A}lthough men who have sex with men ({MSM}) are at high risk of {STI}, their access to tailored healthcare services remains limited in {W}est {A}frica. {W}e assessed the change in {STI} symptoms incidence over time among {MSM} enrolled in a quarterly {HIV} prevention and care programme in four cities in {B}urkina {F}aso, {C}ote d'{I}voire, {M}ali and {T}ogo. {M}ethods {W}e performed a prospective cohort study in {MSM} followed up between 2015 and 2019. {M}en aged over 18 who reported anal sex with another man within the previous 3 months were offered quarterly syndromic diagnosis and treatment for {STI}, as well as {HIV} testing, peer-led counselling and support. {C}ondoms and lubricants were also provided. {T}he change in {STI} symptoms incidence during follow-up was investigated using a non-parametric trend test and mixed-effect {P}oisson regression models. {R}esults 816 participants were followed for a total duration of 1479 person-years. 198 participants (24.3%) had at least one {STI} symptom during follow-up. {O}verall, {STI} symptoms incidence was 20.4 per 100 person-years (95% {CI} 18.4 to 22.6), ranging from 15.3 in {A}bidjan to 33.1 in {O}uagadougou (adjusted incidence rate ratio (a{IRR}) 2.39, 95% {CI} 1.55 to 3.69, p<0.001). {STI} symptoms incidence was 16.8 and 23.0 per 100 personyears in {HIV}-positive and {HIV}-negative participants, respectively (a{IRR} 0.77, 95% {CI} 0.57 to 1.04, p=0.087). {STI} symptoms incidence decreased significantly from 29.9 per 100 person-years in the first 6 months to 8.6 at 30-35 months of follow-up (a{IRR} per 6-month increase 0.84, 95% {CI} 0.77 to 0.92, p<0.001). {C}onclusion {STI} symptoms incidence decreased over time but the overall burden of {STI} appeared to be very high in {MSM} followed up in {W}est {A}frica. {STI} services including counselling, diagnosis and treatment should be reinforced. {L}aboratory tests that allow accurate diagnosis of {STI} are required. {S}trengthening {STI} services will be critical for controlling the {HIV} and {STI} epidemics in this vulnerable population and in the general population.},
