The transmission of hepatitis A in sex is well described by passing from an ass (infected feces) to mouth, and do not forget that there is a vaccine if you want to protect yourself.
But sometimes we see cases of a bacteria called Shigella. This article confirms that it is more common in HIV positive men and in those who use drugs such as mephedrone or methamphetamine (crystal / tina) in sex. Normally it produces a picture of diarrhea but sometimes it can be very severe and requires intervention with antibiotics. As doctors, we must not forget that gastroenteritis after sexual contact can have to do with bacteria that we normally see in infected food / water. If you are experiecing any worrying symptoms, please book a consultation with me.
