<s>[INST] hi my 10 month old baby girl has been having a runny nose, ffever and hight temp for the past few days. sheis also having a very fast heart beat. she is teething at the moment and am not sure if this isthe cause or could she be having a chest infection?. please what should i do, i ahve given her calpol several times today [/INST] Hi madam, your daughter most likely has upper respiratory tract infection which most of the time its viral, and rapid heart beats is normal during fever unless if its above 180 beat / minute.because she is an infant I recommend seeing the pediatrician and do a physical exam because sometimes pneumonia can present with these symptoms and especially high grade fever, and physical exam is very helpful in the diagnosis. I hope this is helpful </s>
