[Screening for sexually transmitted infections in asymptomatic non-pregnant people in the most vulnerable populations: a quick scoping reviewDetección sistemática de infecciones de transmisión sexual en personas no embarazadas asintomáticas pertenecientes a grupos de población vulnerables: una revisión de alcance rápida].

Objectives: To map and synthesize the available evidence on screening strategies for sexually transmitted infections (STIs) in non-pregnant, asymptomatic people in the most vulnerable populations. Methods: This is a quick scoping review, based on the guidelines of the Results: Fifteen studies were included, among them clinical guidelines, observational studies, and systematic reviews, with a predominance of publications from the United States and Australia. The evidence indicates that regular screening for chlamydia, gonorrhea, syphilis, hepatitis B and C, and the human immunodeficiency virus (HIV) is recommended in populations vulnerable to STIs, such as men who have sex with men, sex workers, people taking HIV pre-exposure prophylaxis (PrEP), people deprived of their liberty, and people living with HIV/AIDS (Acquired Immune Deficiency Syndrome). The frequency varies according to the risk profile and anatomical site. Strategies such as opt-out screening and the use of rapid tests at points of care were highlighted, although gaps remain in their large-scale implementation. Conclusion: Screening for STIs in asymptomatic and non-pregnant populations is a relevant public health strategy, especially in the most vulnerable population groups. The findings support the discussions needed to update national guidelines and formulate evidence-informed policies, underlining the need for integrated strategies to increase access to early diagnosis and overcome health inequalities.
