Shigella infection causes gastroenteritis
and can be sexually transmitted
Shigella is a bacterium that can be found in the faeces of a person with shigellosis while they have diarrhoea and for up to a few weeks after the diarrhoea has gone away.
During sex, shigella can be transmitted by the bacteria getting into the mouth. A small amount of the bacteria can cause infection. Infection with shigella can be treated with specific antibiotics.
