As doxyPEP is already happening and intention to use continues to rise independently of formal policy or guidelines: what are the challenges and benefits of this approach to prevent #STI?

Le 190 est un modèle unique de centre de santé sexuelle communautaire.
3 objectifs
• Lutter contre le VIH en accompagnant les hommes gays/bis et les personnes vivant avec le VIH dans un même lieu.
• Prendre soin de ces populations et de leurs besoins de santé spécifiques (vie sexuelle et affective, santé mentale, complications du chemsex, IST, prévention des cancers...) sur le long terme.

Neurocysticercosis school outbreak in Belgium Human cysticercosis results from ingesting microscopic Taenia solium eggs shed by a tapeworm carrier, forming cystic larvae (ie, cysticerci) in tissues. These larvae normally encyst in the pig, the natural intermediate host. Upon consumption by humans, they develop into a new intestinal tapeworm. Affecting the human brain, neurocysticercosis is responsible for a third of epilepsy cases in endemic tropical and subtropical regions.1,2

1/ Imagine being a kid, just vibing at school, when boom—a tapeworm decides to set up camp in your brain. 🧠🏕️
Welcome to the wildest, most unexpected outbreak Belgium has seen. And no, this isn’t an episode of House MD but it reads like it.
