But one thing we might now think of is to avoid our doctor's ties.
The ties could help spread the virus.
Some hospitals have banned the neckwear.
A recent study of ties worn by doctors and staff at a hospital in Queens, showed half the ties carried bacteria that could cause illnesses like pneumonia and blood infections.
Hospitals were always sticklers for clean sheets totally sterile environments, sanitary washstands.
The hospital gives doctors the option to knot or not to knot for now. Some doctors admitted they haven't even worn a tie in over 20 years.
The white coats worn by staff at the Hoboken Medical Center are protected with silver so germs can't stick.
There's now even a market for antimicrobial "safety ties" festooned with decorative diseases like the bestselling H1N1 flu virus, guaranteed to be germ free.
While some doctors feel the profession should present itself formally, those who've been advocating against ties for a long time say get rid of anything which spreads germs.
