According to an Associated Press article on, studies found that viruses were commonly left on TV remotes, light switches and even hotel pens after cold sufferers checked out. What is important to note about these study results is that "the germ testing was done before the rooms were cleaned" by professional cleaning staff within the hotel.

The objective of the study was to test for the survival of rhinoviruses, which cause about half of all colds. Researchers studied 15 people with lab-confirmed rhinovirus colds who spent the night in individual hotel rooms. After they checked out, researchers tested 10 items they had touched to see if they were contaminated.

Results included:
• Seven out of 14 door handles and six out of 14 pens carried the virus
• Six out of 15 light switches, TV remotes and faucets tested positive
• Five out of 15 phones also tested positive
• Only one of the 10 toilet handles tested were found to carry the virus

Researchers insist that the study was conducted to gain a better understanding of germs and how to get rid of them. Regardless, hotel representatives say they have very strict policies on how to disinfect rooms between guests.
