There are many causes of human diarrhea in the world, but a very common one is infection with Entamoeba histolytica This causes the so-called "amoebic dysentery".

"A Entamoeba histolytica is a type of protozoan, and we become contaminated by ingesting water and/or food contaminated with it", explains Vanessa Prado, digestive system surgeon.

This is a condition more common in children and babies, who have the habit of putting their hands in their mouths more often, as well as objects found on the floor, unfamiliar foods, and other items in the early stages of life. Such actions are natural in their development, but can lead to some health complications.

In adults, it is more common for this gastrointestinal disease to arise due to the ingestion of contaminated food. However, it is also common to become infected due to lack of hand hygiene.

Symptoms of Entamoeba histolytica

Although this infection is caused by a very specific protozoan, its symptoms are quite common:

• Diarrhea (which may or may not contain blood and/or mucus);
• Fever;
• Tremors and chills;
• Abdominal pain;
• Vomiting;
• Dehydration.

"The diagnosis is made by a stool test, called a parasitological stool test, with three samples, in which the protozoa are seen inside the stool," continues the doctor.

Treatment and prevention

The treatment for Entamoeba histolytica Generally, the use of an antibiotic associated with a symptomatic (to treat fever, for example) and a dewormer is indicated.

Although common and simple to treat, it is important to diagnose the disease quickly. After all, one of its main complications is dehydration due to the increased number of bowel movements and the presence of vomiting. In more serious cases, prostration (i.e. extreme tiredness) and, in very serious cases, liver abscesses are also possible.

Thus, the best way to prevent this condition is to ensure proper food and hand hygiene, and water filtration. Avoid contact with sewage, untreated water sources, and flood waters as well.
