Amebiasis is a disease caused by the parasite Entamoeba histolytica. It can affect anyone, although it is more common in people who live in tropical areas with poor sanitary conditions. Diagnosis can be difficult because other parasites can look very similar to E. histolytica when seen under a microscope. Infected people do not always become sick. If your doctor determines that you are infected and need treatment, medication is available.
Who is at risk for Amebiasis:

Amebiasis and Entamoeba Infection:
E. histolytica infection can occur when a person:
Amebiasis Signs and Symptoms:
- Only about 10% to 20% of people who are infected with E. histolytica become sick from the infection. The symptoms are often quite mild and can include loose feces (poop), stomach pain, and stomach cramping. Amebic dysentery is a severe form of amebiasis associated with stomach pain, bloody stools (poop), and fever. Rarely, E. histolytica invades the liver and forms an abscess (a collection of pus). In a small number of instances, it has been shown to spread to other parts of the body, such as the lungs or brain, but this is very uncommon.(2)
- Symptoms normally occur 2-4 weeks after infection(2)
- If you think you have been infected with E. histolytica, contact your doctor. They may ask for stool or blood samples to determine whether or not you have been infected.
If your doctor determines that you have been infected with E. histolytica, you may be prescribed HUMATIN™ or another course of antibiotics.(2)
