Hello, My son has got pneumonia on Sep 2023 , hospitalized and doctor said it is due to viral infection and they have provided steroids and after discharge and with 1 week we sent him to school and again he has got fast breathing and wheezing and he has hospitalized and they said some different viral infection and again he has taken steroids and he has become okay . Now oct 2024 again he has got fast breathing and heavy wheezing and got hospitalized now . In his test results all the rsv virus, influenza A , B all negative but his CRP IS 40.9 in blood test. Now again he is getting treated with steroids. Could anyone please explain what may be the cause for the recurrent pneumonia symptoms , please please
