A07.9

Clinical Causes: Consumption of contaminated food or water containing protozoa Poor sanitation and hygiene practices Traveling to regions with high prevalence of protozoal infections Contact with infected individuals or contaminated environments Exposure to contaminated recreational water sources

Key Symptoms: Diarrhea, which may be watery or bloody Abdominal cramps and pain Nausea and vomiting Fever and chills Weakness and fatigue Loss of appetite Dehydration due to fluid loss In some cases, mucus in stool and tenesmus (feeling of incomplete bowel evacuation)

Diagnosis Path: Diagnosing protozoal intestinal disease involves a combination of medical history assessment, physical examination, and laboratory tests. Stool samples are typically examined microscopically for the presence of protozoa, their cysts, or trophozoites. Additional diagnostic tools include PCR testing for protozoal DNA and antigen detection tests to identify specific protozoa species. Proper diagnosis is crucial for guiding targeted treatment and managing the infection effectively.

Treatment Protocols: Treatment typically includes antiparasitic medications tailored to the specific protozoa causing the infection. Common medications may include metronidazole, tinidazole, or nitazoxanide. Supportive care, such as rehydration and electrolyte replacement, is also essential to manage symptoms and prevent dehydration. In cases involving severe or persistent infections, further medical evaluation and follow-up are recommended to ensure complete recovery.
