What is Amebiasis?

Amebiasis was first clearly described by Dr. Fedor Lösch in Russia in 1875, who identified the causative amoeba in dysenteric stools. It was later differentiated from bacterial dysentery, establishing *Entamoeba histolytica* as a distinct human pathogen. This discovery significantly advanced understanding of infectious diarrhea.

Symptoms

Often asymptomatic: Most infected individuals show no symptoms.
Mild Intestinal: Loose stools, abdominal pain, stomach cramps.
Severe Intestinal (Amebic Dysentery): Frequent, bloody stools (dysentery), severe abdominal pain, fever.
Extraintestinal (less common): Liver abscess (fever, right upper quadrant pain), and rarely infections in the lungs or brain.

Transmission

Amebiasis spreads primarily through the fecal-oral route. This occurs when a person ingests cysts of *Entamoeba histolytica* from contaminated food or water. Contamination can happen via infected food handlers, use of human feces as fertilizer, contaminated irrigation water, or direct person-to-person contact in unsanitary conditions.

Contagious Period: Varies by disease

Prevention

Practice good hand hygiene, especially after using the toilet and before preparing or eating food.
Drink safe water (bottled, boiled, or chemically treated) in areas with poor sanitation.
Avoid raw, unpeeled fruits and vegetables, and uncooked foods in high-risk areas.
Ensure proper sanitation and safe disposal of human feces.
No vaccine is currently available for Amebiasis.
