The following are good points by the CDC to help remind you how to be safe:
If you are going into the hospital, ask how they prevent infections and what they do to protect you after surgery to prevent infections. Hospital acquired infections are difficult to treat and can add to your hospital stay.
Keep hands clean - Always make sure everyone washes their before touching you. You may irritate many doctors and nurses, but they are known for not washing their hands as they move from one patient to another.
Become smart about antibiotics - Ask if a test will or has been done to be sure that the right antibiotic is prescribed. Often antibiotics are changed by doctors without tests. Each doctor has their favorite and when it does not work, they move to another antibiotic. Most insurance carriers are now insisting on tests to determine the most effective antibiotic.
