My mother is having mild cough nd cold from last 6 days. Today being the 6th day got a slight fever. Rest there are no symptoms. Oxygen level monitored 2 days back was 97 . She is having paracetamol today onwards and benadryl syrup with regular steam nd kara. She has taken her first vaccine already. Please let me know. Is it something to be worried of. As per her she drank cold water nd continues rains happening in the area due to which she caught cold. No contacts with anyone. No other family members hving symptoms as on date by gods grace. Should I be worried.
