Wash hands frequently. Don't share towels. Throw away facial tissues after you're done. Cover your mouth and nose when you're coughing/sneezing. Discard your antibiotic drops bottle when you're done. Good luck!

Very: Contagious from eye to eye and person to person. Wash sheet, pillowcases, towels and don't share these.
