Hi, may I answer your health queries right now ?  Please type your query here... Hi, I had fever and cough for 4 days and doctor says its viral. How come you guys always says its viral what if a bacteria is residing in kidneys and causing the fever.
Hello, Welcome to Chat Doctor. I have gone through your query and I understand your concern. Your treating doctor that has told you that you might have a viral infection, has evaluated your overall condition and at the end has given the conclusion that the cough and fever is caused from a virus. Actually, we cannot decide to say that the causative microorganism might be a virus, without evaluating your overall condition and associated symptoms. Bacterial infections have normally more severe symptoms than viral infections. If you had a kidney infection caused from a bacterium, you would have other related symptoms, and one of them wouldn't be the cough you have as a symptom. Hope I answered to your question. For further concerns feel free to ask again. Take Care,
