Shigella is a type of bacteria that causes severe stomach upset. It is passed on through infected poo, either sexually or through contaminated food.  It is more common in men who have sex with men.

Symptoms are typically seen between 1 and 4 days after exposure and are commonly mistaken for food poisoning.


  • Diarrhoea
  • Stomach cramps
  • Fever
  • Sickness

Shigella is very infectious. Although symptoms can be unpleasant, in most cases they will subside within a week. However, some individuals need hospitalisation and require intravenous antibiotic treatment. Effective antibiotic treatments are limited for this extremely resistant strain.
