Chronic Bacillary Dysentery

Chronic bacillary dysentery mostly results from inadequate treatment during the acute phase, or from various causes such as malnutrition, rickets, intestinal parasitosis, and poor dietary hygiene habits. It often presents with atypical dysenteric symptoms such as abdominal pain, diarrhea, and bloating. Exposure to cold or eating raw/cold foods can trigger acute exacerbations with diarrhea, abdominal pain, and bloody purulent stool.

Common Symptoms

Abdominal tenderness; abnormal defecation frequency; diarrhea; abdominal pain

Causes and Pathogenesis

History of unclean diet or contact within one week before onset, and local epidemic situation of the disease.

Treatment

Drug therapy, supportive therapy

Preventive Measures

Professional guidance: 1. Identify triggers and provide symptomatic treatment. Avoid overexertion, keep the abdomen warm, and avoid raw/cold foods. Debilitated patients should receive immunostimulants promptly. When intestinal flora imbalance occurs, avoid abusing antibacterial drugs; immediately discontinue resistant antibacterial drugs. Switch to enzyme preparations or Lactobacillus to favor intestinal anaerobic growth. 2. For patients with persistent intestinal mucosal lesions, add retention enema therapy. Note: (1) Source of infection: Includes patients and carriers; among patients, acute typical and chronic occult bacillary dysentery are the most important sources. (2) Transmission route: Shigella is excreted in feces and transmitted through contaminated hands, food, water, or daily contact, or indirectly through flies and cockroaches, ultimately infecting susceptible individuals through the mouth. (3) Susceptibility: The population is generally susceptible; preschool children are more commonly affected, related to poor hygiene. Adults are associated with reduced resistance and more exposure; there is no solid immunity after infection, and no cross-immunity between groups and serotypes, leading to repeated infections.

Department to Visit

It is recommended to visit the Infectious Diseases department; an appointment can be booked on this platform before the visit.
