Mate shigella

Shigella is a bacterium (germ) that can cause gastroenteritis.

You can catch the Shigella infection (or Shigellosis) by consuming contaminated food or water.

You usually get symptoms one to three days after being infected. Symptoms include diarrhoea, which may contain blood or mucus, stomach cramps, feeling sick and vomiting and a fever. The symptoms usually clear up in three to seven days.

Treating Shigella

There is no medicine for Shigella. The treatment is aimed at relieving symptoms. Rest and drink plenty of fluids to prevent dehydration. See the self-care section on the gastroenteritis page for more details.

Doctors sometimes prescribe antibiotics for Shigella.

Getting help for Shigella

You should see your GP if you have bloody diarrhoea or a fever or if your symptoms have not gone away after seven days. You should also see your GP if you're very unwell or have a weakened immune system.

You should take your child to your GP if they aren't drinking, if they're passing less urine than usual, have a dry mouth or sunken eyes or if they seem drowsy.

Avoiding spreading Shigella

To reduce the risk of spreading the infection, it's important to have good hand hygiene. This includes washing your hands with soap and water, especially after using the toilet.

Try to avoid preparing food if you have Shigella. If you do prepare food, make sure you wash and dry your hands well first. Follow this food safety advice.

Stay away from work, community gatherings and school or preschool until you or your child have been free of symptoms for 48 hours. This includes the last time you had diarrhoea.

You should wait for at least two weeks after the last episode of diarrhoea before you go swimming in a pool.
