Frequently Asked Questions
What are the common symptoms of malaria (ICD-10 B50-B54)?

Common symptoms of malaria include fever, chills, headache, nausea, vomiting, and muscle pain. Severe cases may lead to anemia, respiratory distress, or organ failure. Early diagnosis and treatment are crucial.

How is giardiasis (ICD-10 B65) diagnosed and treated?

Giardiasis is diagnosed through stool sample analysis to detect Giardia parasites. Treatment typically involves antiprotozoal medications such as metronidazole or tinidazole. Hydration and supportive care are also important for recovery.

What preventive measures can be taken against toxoplasmosis (ICD-10 B58)?

Preventive measures for toxoplasmosis include cooking meat thoroughly, washing fruits and vegetables, avoiding unpasteurized dairy products, and practicing good hygiene, especially after handling cat litter or soil. Pregnant women should take extra precautions to avoid infection.
