My daughter had a bad bout of coughing around 26th December and then she was given moxikind cv. In 2 weeks she felt a little better and started going school but around 16th Jan she has bad cough again and by then my wife and my younger daughter including me started having sore throat first and then coughing. I visited doc again and she and her sister have been prescribed antibiotics merosure, zinox. For last 3 days starting from 19th Jan both of them have started fever. Younger one ia having fever every 6 hours whereas the older one is having every 12 hour or more. Me and my wife dont have fever yet but feel sick and have elevated temperatures Chest x ray was done for both my daughter and the report said "infective changes seen in both lower lungs" CBC is normal for my elder daughter and crp is 0.9 mg/dl I am a little concerned at the moment and I want to rule out it is not TB. From what I said about x ray report and history can we rule out tb? What you think is possible reason
