Hi, I understand that your child has a productive cough with a low-grade fever for almost a week. He is otherwise fine and active and has no respiratory symptoms. Flu and streptococcal throat infection have been ruled out. His symptoms go in favor of a viral upper respiratory infection and possible sinusitis. As long as he has a cough and a fever, he is contagious. I would recommend that you treat him with Paracetamol syrup for fever, an anti-allergic tablet like cetirizine, plenty of lukewarm fluids orally, a mixture of honey with ginger is also helpful. The cough can take more than a week to clear up. In case the fever persists or rises with an increase in cough or difficulty in breathing, you must consult your doctor again. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Anil Kumar Bhatnagar, Neonatologist
