Amoebic Dysentery
Condition
(Amebiasis)
Definition
Amoebic dysentery is an intestinal illness. If left untreated, it can cause serious problems or even death.
Causes
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

Risk Factors
This condition is more common in tropical, developing countries. Other things that may raise the risk are:
- Spending time in places that have poor sanitary conditions
- Living in institutions with poor sanitary conditions
- Oral-anal contact
- Household contact with an infected person
- Men who have sex with men
Symptoms
Most people do not have symptoms. Those who do may have:
- Loose stool (poop) that is bloody, watery, or contains mucus
- Belly pain
- Problems passing stool
- A constant feeling of needing to pass stool
- Fever
- Bleeding from the rectum
- Nausea
- Lack of hunger
Diagnosis
The doctor will ask about symptoms and past health. A physical exam will be done.
Stool (poop) will be tested to look for signs of infection. Blood tests may also be done. These tests will be used to confirm the diagnosis.
Treatment
Antibiotics will be given to treat amoebic dysentery. More than one may be used. Probiotics may also ease symptoms.
Prevention
In poor sanitary conditions, the risk of this problem can be lowered by:
- Drinking only bottled water
- Using iodine to disinfect nonbottled water
- 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
