This is a bacterial infection that causes serious stomach cramps and disease. Shigella can easily be spread from one person to another through rimming (anal contact) and from oral contact with contaminated skin including skin in the groin area., the testicles and the penis. Shigella can also be spread via contaminated food and water. People with HIV are more likely to have complications from Shigella infections.

Other bugs commonly acquired through oral-anal sex that can cause stomach pain and diarrhea are the three parasites such as giardia, amebiasis, and cryptosporidium, and the viral Hepatitis A. Shigella is treated with antibiotics. Very thorough washing of your genitals and after sex can help prevent Shigella and other infections, as well as barrier (cut-up condoms, dental dams, or household plastic wrap) for any sexual activities.
