Amoebic dysentery is an intestinal illness.
This problem is caused by an infection with a specific parasite. A person may become infected with the parasite by:
- Putting something in their mouth that has touched the stool of an infected person
- Swallowing water or food that is contaminated
- Swallowing eggs picked up from contaminated surfaces or hands

Things that may raise the risk of this problem are:
- Spending time in places that have poor sanitary conditions, especially tropical developing countries
- Living in institutions with poor sanitary conditions
- Oral-anal contact
- Household contact with an infected person
Most people do not have symptoms. Those who do may have:
You will be asked about your symptoms and health history. A physical exam will be done.
Your stool will be tested to look for signs of infection. Blood tests may also be done.
Antibiotics will be given to treat amoebic dysentery. More than one may be used. Probiotics may also ease symptoms.
The risk of this problem in poor sanitary conditions can be lowered by:
- Drinking only bottled water or water that has been boiled for at least 1 minute
- Drinking other fluids (like soda) from sealed cans or bottles
- Not adding ice cubes to drinks
- Not eating unpeeled fruits and veggies
- Not eating or drinking unpasteurized milk, cheese, or dairy products
- Not eating foods or drinks sold by street vendors
- Washing hands often with soap and water or using hand sanitizer
