Question
How can amoebiasis be prevented?
✓
Answer
Prevention of amoebiasis is to be done at two levels, viz. at home and at endemic level.
1. Prevention of the spread of amoebiasis at the home level:
- Washing hands with soap and water after using the toilet or changing a baby’s diaper and before handling and eating food.
- Cleaning bathrooms and toilets properly with germicides.
- Avoiding raw vegetables when in endemic areas where they are grown in soil fertilized by human faeces.
- Boiling and purifying the drinking water.
2. Prevention of the spread of amoebiasis at endemic level:
- Avoiding consumption of street foods especially in public places.
- Following good sanitary practice, as well as using proper sewage disposal or treatment.
- E. histolytica cysts are usually resistant to chlorination; therefore sedimentation and filtration of water supplies are necessary to reduce the incidence of infection.
- Avoiding shared towels or face washers.
