Bacillary dysentery is an intestinal infection caused by a group of Shigella bacteria which can be found in human gut.
The illness is characterised by sudden onset of fever, diarrhoea with abdominal cramps and nausea or vomiting. The stool may contain blood and mucus. Mild and asymptomatic illness can occur. Complications include toxic dilatation of large intestine and acute kidney disease.
Mode of transmission
Bacillary dysentery is transmitted directly by faecal material of a patient or carrier, or indirectly through contaminated food and water. Infection may occur after consuming a small number of the germs. Therefore, chance of spreading among household members, in school or institutions can be very high. It occurs more commonly amongst young children.
Usually 1 - 3 days, but can be up to 7 days
Infected persons in schools or institutions should be isolated. They should observe personal hygiene to avoid infecting other persons. Treatment includes fluid replacement and antibiotics.
