Editor’s Note:
This article was originally prepared by medical professionals from International SOS in response to a health concern affecting expatriates in Indonesia at that time. The medical information remains accurate; however, conditions in Indonesia have evolved.
Today, in major urban areas such as Jakarta, the risk of contracting amebiasis is generally low for expatriates who follow normal hygiene practices. That said, the disease has not been eliminated and may still be more prevalent in rural areas, regions with limited sanitation infrastructure, or in situations involving contaminated food or water.
Expats traveling outside major cities or consuming improperly handled food should continue to take appropriate precautions.
Amebiasis is a parasitic disease found worldwide, especially in areas with poor sanitation, tropical climates, and/or places where people live in crowded conditions.
People are infected via the fecal-oral route, by ingesting the parasite’s cyst. These cysts are present in the feces of an infected person, and food or water can become contaminated if proper hygiene is not maintained.
Approximately 10 percent of those infected become ill, usually within a month. Symptoms may include:
- Stomach pain
- Diarrhea, which may be bloody and painful
- Weight loss
- Fever
These symptoms can sometimes resemble other common illnesses in Indonesia such as gastroenteritis or typhoid fever, making proper medical diagnosis important.
In rare cases, the infection can spread through the bloodstream to organs outside of the intestinal tract, such as the liver, lungs, or brain.
Treatment is typically with appropriate antibiotics prescribed by a medical professional. It is important to avoid using anti-diarrheal medications without medical advice, as these may worsen the condition.
There is currently no vaccine for amebiasis. Prevention remains the most effective approach and includes:
- Practicing good personal hygiene (especially handwashing)
- Drinking bottled or properly filtered water (link drinking water safety in Indonesia)
- Ensuring food is freshly prepared and thoroughly cooked (link food preparation and hygiene tips)
- Avoiding food from questionable hygiene sources
While the overall risk for expatriates living in well-developed urban areas has decreased, infections can still occur, particularly when traveling or when food safety standards are compromised. In some cases, other parasitic infections such as intestinal worms may also be a concern depending on living conditions and hygiene practices.
