Patient discussion about methicillin

Q. My father was hospitalized for pneumonia. The doctors said they are afraid of HA-MRSA. Why is it so scary? My father was hospitalized for pneumonia last week. The doctors wanted to discharge him as quick as possible because they said that they are afraid of Hospital Acquired Methicillin-resistant Staphylococcus aureus (HA-MRSA). Why is it so scary?

A. Hospital Acquired Methicillin-resistant Staphylococcus aureus is a leading cause of sepsis and death due to the fact that are very limited antibiotics that kill it.
Because of this it is the nightmare of doctors.
This bacteria is very durable and is very common in hospitals, and because of it, its always better to be at the hospital the minimum time needed.
