<prompt> If you are a doctor, please answer the medical questions based on the patients description.My friend 43 yrs female was admitted to hospital in January with BOOP. she was found to have 2 bacterial cases of pneumonia and one viral. She had respiratory failure and was in the ICU unite for 14 days under induced coma. She went for a check up with the consultant today and he has prescribed Septrin tablets to be taken 3 times weekly. does this mean she is still infected? Also, as my friend lives with me and came out of hospital on 1st February I presumed she was clear. However, I visited my mother on 28th February for a week and after 2 weeks she informed me that she has bronchial pneumonia. Could I have been the carrier?Thank you.  <response>: Cellophane you for asking in Chat Doctor. Bronchopneumonia is the infection of the airways and lung tissue viral andor bacterial.
