Bacillary dysentery and amebic dysentery

Bacillary Dysentery

Bacillary dysentery is a common intestinal infectious disease caused by infection with bacteria of the Shigella genus. The sources of infection are patients and carriers. The main transmission routes include contact with contaminated daily necessities, water sources, and food from infected individuals, or transmission through biological vectors such as flies carrying Shigella.

The general population is susceptible, and infection provides short-term immunity of about 1 to 12 months, with no cross-immunity between different bacterial groups (types). The incubation period is typically 1 to 3 days, with a maximum of 7 days. Typical symptoms manifest within 24 to 48 hours after infection and include abdominal pain, diarrhea, fever, fatigue, anorexia, mucus or bloody stools, and tenesmus. Severe cases in children may lead to toxic encephalopathy.

To prevent and control bacillary dysentery, it is important to avoid contact with infected individuals and their belongings, and to cultivate good personal hygiene and dietary habits.

Amebic Dysentery

Amebic dysentery is a digestive tract infectious disease caused by the parasitic amoeba Entamoeba histolytica, which resides in the colon. Chronic patients, those in the recovery phase, and asymptomatic cyst carriers are the main sources of infection. The primary mode of transmission is through the ingestion of food, water, or utensils contaminated with amebic cysts. Insects such as flies or cockroaches can mechanically spread the cysts, contributing to transmission.

The general population is susceptible, and the incubation period varies from one week to several months, mostly ranging from 1 to 2 weeks. Typical clinical manifestations include fever, abdominal pain, diarrhea, and dysentery with jelly-like mucus and blood. In some cases, patients may exhibit mild symptoms such as slight abdominal bloating, pain, or constipation. However, during acute episodes, severe diarrhea and symptoms like jelly-like stools may occur, and some serious cases may develop complications such as liver abscesses.

To prevent and control amebic dysentery, it is important to implement safe disposal methods for feces to eliminate cysts, protect water sources and food from contamination, boil drinking water, and maintain environmental hygiene while controlling harmful insects. Additionally, practicing regular handwashing before meals and after using the toilet enhances personal hygiene and self-protection.
