Shigellosis Fact Sheet for MSM
Current Situation
The Minnesota Department of Health (MDH) has
observed an increase in reported shigellosis
infections in Minneapolis among men who have sex
with men (MSM). Four (4) cases were diagnosed in
November among white, non-Hispanic, MSM.
Sexual contact is the likely route of transmission.
Three cases were hospitalized, and two of the cases
had been previously diagnosed with HIV infection.
Shigellosis Cause and Symptoms
Shigellosis is an infectious disease caused by
bacteria called Shigella. Symptoms include diarrhea
(often bloody), fever, and stomach cramps starting a
day or two after exposure to the bacteria. Mild cases
of shigellosis usually resolve in 5 to 7 days. People
with compromised immune systems and lower CD4
counts due to HIV infection are more likely to have
severe symptoms which may result in a prolonged
illness and even hospitalization.
Spread of Shigellosis
Shigella can pass from one infected person to
another. Diarrheal stool of infected persons contain
Shigella that spread while they are sick and for up
to a week or two afterwards. Most Shigella
infections are passed from stool or soiled fingers of
one person to the mouth of another person. This
happens when basic hygiene and hand washing
habits are inadequate and can happen during certain
types of sexual activity, such as rimming (oral-anal
contact) and from oral contact with contaminated
skin, including skin around the buttocks, groin area,
testicles, and the penis.

Prevention
The most effective way to reduce the risk of
contracting Shigella is to wash hands thoroughly
after any sexual activity, after touching items used
during sex like used condoms and sex toys, after
going to the toilet, and before handling food. Clean
sex toys before each use. Use a dental dam for
rimming when having sex with casual partners and
use gloves for anal fisting and fingering. Anyone
who has any symptoms of Shigella should see their
health care provider.
People who work in the food industry, health care
workers, and child care workers with acute
vomiting or diarrhea should stay out of work while
they have symptoms, and should contact their health
care provider for evaluation.
Treatment and Recovery Precautions
Persons diagnosed with shigellosis may benefit
from treatment with antibiotics and should contact
their health provider if they develop symptoms of
shigellosis. Persons should also avoid sex while
they have symptoms and for at least 7 days after the
symptoms clear.
Individuals who are healthcare workers, food
workers, or who work in child care setting should
not work until they either: 1) have been treated with
an antibiotic for at least 24 hours and
gastrointestinal symptoms have ceased; or 2) have
had two culture-negative stool samples collected at
least 24 hours apart.
