Acute Communicable Disease Control
Shigellosis (Shigella)

HEALTH ALERT: CLUSTER OF SHIGELLA INFECTIONS AMONG MEN IN LOS ANGELES AND OTHER SOUTHERN CALIFORNIA COUNTIES

Currently, an increase in cases of an uncommon type of Shigella is occurring in Los Angeles and other counties in California. There have been two deaths. All cases have been among men, many self-identified as gay or bisexual. Men who have sex with men (MSM) are at increased risk for this disease.

The Los Angeles County Department of Public Health recommends:

MSM should be aware of the outbreak and that Shigella can be a severe illness, particularly in those with reduced immunity
Changing sexual practices to avoid oral-anal contact will help prevent disease
Any MSM with fever and diarrhea should see their healthcare provider
A stool culture should be done to identify whether the cause is Shigella
Antibiotic treatment will shorten duration of illness and reduce the risk of transmission
Abstaining from sex for at least 2 weeks after infection is important to further reduce transmission (and then maintaining safe sex practices when one resumes sexual relations)
Those with Shigella infection should not prepare food for others while sick
People who work in healthcare, food service, or childcare, might be kept from work until they recover

LAC DPH Health Alert: Cluster of Shigella flexneri Infections among Men in Los Angeles and Other Southern California Counties



What is Shigellosis?
Shigellosis is caused by a Gram-negative bacillus with 4 main serogroups: Shigella dysenteriae (group A), S. flexneri (group B), S. boydii (group C) and S. sonnei (group D). Incubation period is 1-3 days. Transmission occurs when individuals fail to thoroughly wash their hands after defecation and spread infective particles to others, either directly by physical contact, including sexual behaviors, or indirectly by contaminating food. Infection may occur with ingestion of as few as 10 organisms. Common symptoms include diarrhea, fever, nausea, vomiting, and tenesmus. Stool may contain blood or mucous. In general, the elderly, the immunocompromised, and the malnourished are more susceptible to severe disease outcomes.
