About Shigella Infection Among Gay, Bisexual, and Other Men Who Have Sex with Men

Overview

Gay, bisexual, and other men who have sex with men* are among groups at high risk for infection with Shigella germs. This infection is called shigellosis. Shigella germs spread easily and rapidly among people, including during sexual activity.

Men who have sex with men are particularly at risk for infections with antimicrobial-resistant Shigella. Antimicrobial resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Shigella germs are increasingly resistant to antibiotic treatment.

Causes and spread

Antimicrobial-resistant Shigella

Infections with antimicrobial-resistant Shigella have been on the rise in the United States since 2013. Most people with Shigella infection—including those infected with antimicrobial-resistant Shigella—recover within 5 to 6 days without antibiotics. However, some people need antibiotics, including people who have a severe or long-lasting infection or are at risk of one.

People at risk of a severe or long-lasting infection include those with a weakened immune system due to certain medical conditions (such as infection with HIV) or treatments (such as chemotherapy for cancer). These people are also at increased risk for the infection spreading into the blood, which can be life-threatening.

Shigella germs can spread during sexual activity

Shigella germs pass from the poop (stool) or unclean fingers of one person to the mouth of another person. This can happen during sexual activity through:

• Direct sexual contact: Anal or oral sex, or anal play (rimming, fingering)
• Indirect sexual contact: Handling contaminated objects, such as sex toys, used condoms or barriers, and douching materials

Symptoms typically start 1 to 2 days after swallowing the germs and include diarrhea, fever, and abdominal pain. However, not everyone with a Shigella infection has symptoms.

Shigella germs can be found in the poop of people with diarrhea and can continue to be found in their poop for up to two weeks after the diarrhea has gone away.

Protect yourself and your partner

Take steps to reduce oral contact with poop during sex:

• Wash your hands, genitals, and anus with soap and water before and after sexual activity. Wash hands, especially after touching sex toys, used condoms or barriers, and douching materials.
• Use barriers like condoms or dental dams during oral sex and oral-anal sex.
  • Use condoms the right way, every time you have anal sex or oral sex. Condoms will also help prevent other sexually transmitted diseases.
• Use latex gloves during anal fingering or fisting.
• Wash sex toys with soap and water after each use and wash hands after touching used sex toys.

If you or your partner has been diagnosed with shigellosis, do not have sex. To reduce the chance of Shigella germs spreading, wait at least two weeks after diarrhea ends to have sex.
