Factors associated with sexually transmitted shigella in men who have sex with men: A systematic review

Abstract

Background: Outbreaks of sexually transmitted shigella have been reported in men who have sex with men (MSM) since the 1970s and present a major public health issue. Understanding the factors associated with the sexual transmission of shigella may inform future control strategies.

Methods: We systematically searched four bibliographical databases (January 2000–February 2022) for manuscripts in English. We used a two-stage process to assess eligibility: the primary author conducted an initial screen and then three authors conducted independent full-text reviews to determine the final eligible manuscripts. We only included manuscripts that included MSM diagnosed with sexually transmitted shigella where specific factors associated with transmission were identified.

Results: Thirteen manuscripts met the inclusion criteria that included 547 individuals. Sexually transmitted shigella in MSM was associated with: residing in a capital city/urban region, living with HIV (including engaging in seroadaptive sexual behaviour, having a low CD4 count, having a HIV viral load >100 000 and not engaging with HIV care), using HIV pre-exposure prophylaxis, use of geospatial mobile phone applications to meet sexual partners, visiting sex on premises venues, chemsex and recreational drug use, sexual behaviour (including multiple non-regular sexual partners and oral-anal sexual contact) and concomitant STIs.

Conclusion: We have highlighted some important risk behaviours and factors that are associated with sexually transmitted shigella in MSM that can be used to target future shigella control interventions.
