<s>[INST] My 56 yr old daughter had a total hip replacement Monday, started running a fever that night, is diagnosed with infiltration pneumonia in both lungs. They say it is contagious and not sure they want me to come out. How contagious is it and would I be OK if I wore a mask and took other precautions? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Yes, pneumonia is contagious. It can be prevented by wearing mask. So better to wear mask when you are near your daughter. You should maintain good immunity to prevent infection. Follow proper handwashing, eat healthy food and Chat Doctor.  Consult doctor and get done chest x-ray if you develop cough, expectoration and fever. No need to fear but better to be cautious. Hope I have solved your query. Wish you good health. Thanks. </s>
