Hi, my daughter is 3.5 years old. She had a viral infection due to which she had cough and loose motion. The doctor treated her for that. That was last week. Her dosage was supposed to end today. Suddenly, she developed high fever with chills yesterday evening (103.5F). Meftal P worked and it brought down the chills and temperature instantly. After that she was perfect for 8 hours. Then suddenly she started shivering again and temperature started to rise. We gave her crocin first which didnt work, then we gave her meftal P which made her fine again. Do you think this is viral fever or is it malaria?
