Causes of Dysentery

Dysentery is spread from person to person through poor hygiene measures, for example not washing your hands after using the toilet. In the UK, most cases are spread through families and where people are in close contact, such as schools, nurseries, military bases and day-centres. The disease can be spread up to four weeks from infection into the body.

Dysentery is also spread through food that has come into contact with water contaminated with human sewage, such as in countries with poor sanitation systems. This is why more severe dysentery is more common in developing countries, where water supplies and sewage disposal are inadequate or where human faeces are used as a fertilizer.
