Shigella Bacteria

 

The Shigella bacteria is actually a family of bacteria that can cause diarrhea in humans. Shigella infections result from the passing of bacteria from stools or soiled fingers of one person to the mouth of another. So a single exposure in a day-care setting or school, by contaminated food, or by swimming in contaminated water can cause the infection.

Symptoms include fever, stomach cramps and diarrhea. The diarrhea can be watery or contain blood or mucous, and usually resolves in about 5 to 7 days. The greatest risk is dehydration, so it’s important to drink lots of clear liquids. If you or your child have signs of dehydration, including high fever, lack of tears or urine, or listlessness, seek medical attention because intravenous fluids may be needed.

The key to avoiding Shigella is good hygiene. That means lots of hand washing with soap, before meals and after using the toilet. Wash for at least 10 seconds-and make sure to get under your nails, as well. Take the towel you use to dry your hands to turn off the faucet so you avoid getting re-contaminated. Wash your hands and the baby’s hands after changing diapers, and dispose of the diapers properly. People with diarrhea should not prepare meals or pour water.

If you or someone in your household has symptoms, see your doctor. A culture may be taken and the doctor may prescribe antibiotics to shorten the time of the illness and to prevent the spread of the bacteria. Also, avoid anti-diarrheal agents like Imodium or Lomotil which could make the illness worse.
