A case of reactive arthritis secondary to sexually acquired Shigella flexneri

We present the first documented case of reactive arthritis (ReA) secondary to sexually acquired Shigella flexneri infection. The case occurred in the context of a recent change in Shigella epidemiology in England where non-travel associated cases are now contributing the majority of diagnoses. Such non-travel associated cases are occurring predominantly in men who have sex with men with high sexual risk taking behaviour reflecting the importance of the sexual history when assessing a man with Shigella infection who has not travelled. We suggest Shigella can be thought of as a cause of sexually acquired ReA and not just a form of enteric ReA. Referral to sexual health services for further management is essential
