Amoebiasis Epidemiology
- Worldwide distribution, but prevalence higher in tropical areas!
- Susceptibility: children are particularly susceptible, but the disease is less common in those under 5 years. Liver abscesses are found predominantly in males.
- The main transmission mode is by ingestion of cysts with faecally contaminated food or water. The cysts survive for weeks or months in the soil (if temperature is not below 4 or above 40 °C). They are chlorine resistant!
- Asymptomatic cyst passers are important for spreading the disease!
