text: Most health care providers adhere to the best preventive - washing hands.  They do so between patients, procedures, you name it.  It will work for you.  Beyond that, don't brush off symptoms thinking they will pass in time.  Have it checked.  Keep in mind, if your in your first year in a health care field, illnesses can be rampant until your immune system builds up.  That is a problems with kids today.  Many are not allowed to get dirty leaving nothing for their immune system to fight.  Same with animals.  Kids that are around cats and dogs from an early age will build up imunitites and not become allergic.  Hope this helps.
