Clinical Classification Guidelines
Inclusion Terms
- Bacillary dysentery NOS
Medical Intelligence & Overview
Shigellosis, also known as bacillary dysentery, is an intestinal infection caused by a group of bacteria called Shigella. It leads to inflammation of the digestive tract, resulting in symptoms like diarrhea, fever, and stomach cramps. The condition can affect individuals of all ages, particularly in areas with poor sanitation. The ICD-10 code A03.9 specifically covers cases of shigellosis that are unspecified, meaning detailed subtypes or causes are not specified in the diagnosis.
Causes & Symptoms
Clinical Causes: Ingestion of contaminated food or water containing Shigella bacteria Person-to-person contact with an infected individual Poor sanitation and hygiene practices Travel to regions with high incidence of shigellosis Consumption of contaminated produce or improperly cooked foods
Key Symptoms: Frequent, watery diarrhea – sometimes bloody Abdominal cramps and pain Fever and chills Nausea and vomiting Tenesmus, or a feeling of incomplete bowel evacuation General malaise and dehydration in severe cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis primarily involves stool tests to identify Shigella bacteria. Laboratory analysis can confirm the presence of the bacteria and help determine the specific strain involved. Physicians may also assess symptoms and medical history to support the diagnosis. In some cases, blood tests or imaging may be used to rule out other conditions or assess complications.
Treatment Protocols: Treatment typically includes rehydration to prevent dehydration caused by diarrhea and, in some cases, antibiotic therapy to eliminate the bacterial infection. The choice of antibiotics may depend on local antibiotic resistance patterns. Rest, proper hydration, and a gradual return to a normal diet are essential components of care. Severe cases may require hospitalization, especially in vulnerable populations such as young children or the elderly.
