Gastroenteritis – Amoebiasis in Grand Rapids, Michigan

Amoebiasis is a type of gastroenteritis (often called “gastro”) caused by a parasite that infects the bowel, most commonly Entamoeba histolytica. While amoebiasis is more common in countries with poor sanitation, Grand Rapids residents can still be affected, especially after international travel.

Young to middle‑aged adults are most commonly affected, but anyone can become infected.

In Grand Rapids, amoebiasis is an important consideration for:

People returning from travel to developing countries
Students and staff at local colleges who study or volunteer abroad
Mission and church groups traveling from West Michigan
People living in shared housing or crowded conditions

Local healthcare providers such as Spectrum Health, Trinity Health Grand Rapids, Metro Health, and Mercy Health can diagnose and treat amoebiasis if you become ill.

What Causes Amoebiasis?

Amoebiasis occurs when the parasite or its eggs (cysts) are swallowed. This usually happens through:

Drinking contaminated water
Eating contaminated raw vegetables and fruit
Eating food handled by someone who is infected and has not washed their hands properly

People with amoebiasis pass the parasite in their stool (poop). The infection can spread when:

Toilets and bathrooms are not cleaned properly
Hands are not washed well after using the restroom or changing diapers
Food is prepared by someone with poor hand hygiene
There is unprotected oral–anal sexual contact

Some people carry the parasite without any symptoms but can still spread it to others.

Signs and Symptoms of Amoebiasis

Symptoms may appear days, months, or even years after infection, but most people become ill 2 to 4 weeks after exposure.

Common symptoms include:

Diarrhea (sometimes with blood or mucus)
Stomach cramps and abdominal pain
Fever
Nausea and fatigue
Unintentional weight loss (in longer‑lasting infections)

In some cases, the parasite can travel from the bowel to other parts of the body and cause abscesses, most commonly in the liver. Liver abscesses can cause:

Pain in the upper right side of the abdomen
Fever and chills
Feeling generally unwell

If you have recently traveled overseas and develop diarrhea, especially bloody diarrhea or persistent stomach pain, seek medical care promptly in Grand Rapids.

Amoebiasis and Grand Rapids Travelers

Grand Rapids residents often travel for business, education, mission work, and tourism. Amoebiasis is more common in parts of:

Central and South America
Africa
Asia
The Middle East

When traveling from West Michigan to areas with limited sanitation, remember the rule:

“Cook it, peel it, or leave it.”

To reduce your risk:

Eat only well‑cooked foods, served hot
Avoid raw vegetables unless you can confirm they were washed in safe water and cooked
Eat fruit you can peel yourself (like bananas, oranges)
Avoid salads, unpeeled fruit, and street food in high‑risk areas
Drink bottled, boiled, or properly filtered and chlorinated water
Avoid drinks containing ice, unless you are sure the ice is made from safe water

If you become sick during or after travel, local providers in Grand Rapids can help. Stool (feces) testing is usually needed to confirm amoebiasis.

When to See a Doctor in Grand Rapids

Contact a healthcare provider if you:

Develop diarrhea lasting more than 2–3 days
Have bloody diarrhea or severe stomach cramps
Have a fever with diarrhea
Recently returned to Grand Rapids from overseas and developed gastroenteritis
Have ongoing abdominal discomfort, weight loss, or fatigue after travel

You can seek care at:

Your primary care provider or family doctor
Local urgent care centers in Grand Rapids
Hospital emergency departments (Spectrum Health, Trinity Health Grand Rapids, Metro Health, Mercy Health) for severe symptoms

Your doctor may order a stool test to look for Entamoeba histolytica. If you are diagnosed with amoebiasis, prescription medication is available and usually very effective.

Staying Home From Work, School, and Childcare

To prevent spreading amoebiasis in the Grand Rapids community:

Do not attend work if you are a food handler, healthcare worker, or caregiver until your diarrhea has completely stopped.
Children must not attend school or childcare (including daycare centers and preschools) while they have diarrhea.
Follow your doctor’s advice about when it is safe to return to work or school.

This is especially important in shared environments common in Grand Rapids, such as schools, long‑term care facilities, and healthcare settings.

Preventing the Spread of Amoebiasis at Home

Proper hygiene is essential to protect your family and roommates, especially during Michigan’s colder months when people spend more time indoors and infections can spread more easily.

Proper Handwashing

Wash hands thoroughly with soap and warm running water for at least 15 seconds:

After using the toilet
After changing diapers or assisting someone with toileting
Before preparing or eating food
After cleaning the bathroom or handling soiled laundry

Dry hands with:

A clean towel, or
Paper towel, or
An air dryer

Avoid touching food until hands are completely dry.

Cleaning Bathrooms and Toilets

Clean bathrooms regularly, paying special attention to:

Toilet seats and flush handles
Sink taps (faucets) and handles
Bathroom counters and door handles

Use household disinfectant according to the manufacturer’s instructions.

To reduce the risk of spreading infection:

Do not share towels, washcloths, or face washers
Provide each family member with their own towel
Wash soiled towels and clothing in hot water

Safe Food Handling in Grand Rapids Homes and Restaurants

Food handlers at home and in restaurants around Grand Rapids should:

Wash hands thoroughly with soap and warm running water before touching food and after using the restroom
Ensure raw vegetables are thoroughly washed and, when appropriate, fully cooked
Reheat leftovers so the internal temperature reaches at least 75°C (167°F)
Follow proper microwave cooking instructions to ensure food is heated evenly

Restaurants and food businesses in Grand Rapids are regulated by local health authorities, but good hygiene at home is just as important.

Sexual Transmission

Amoebiasis can also be spread through unprotected oral–anal sexual contact. To reduce risk:

Use barrier protection (such as dental dams) during oral–anal contact
Wash the anal area and hands thoroughly before and after sexual activity
Avoid sexual activity involving contact with stool

If you are concerned about possible exposure, talk with a healthcare provider in Grand Rapids about testing and prevention.
