Doorknobs, TV remotes, refrigerator handles and other commonly touched household surfaces are hotbeds of cold germs, which can survive on those surfaces for two days or longer, says a University of Virginia study.
The study included adults with cold symptoms who were asked to name 10 places in their homes they had touched in the preceding 18 hours. The researchers then went to the participants’ homes to hunt for cold germs, the Associated Press reported.
“We found that commonly touched areas … were positive (for cold germs) about 40% of the time,” said ear, nose and throat specialist Dr.Birgit Winther. Cold germs were found on six of 10 doorknobs, eight of 14 refrigerator handles, three of 13 light switches, six of 10 TV remote controls, eight of 10 bathroom faucets, four of seven phones, three of four dishwasher handles, and three of three salt and pepper shakers.
The study was presented in October, 2008 at the National Conference on Infectious Diseases in Washington, D.C., the AP reported.
