Are you one of those people who just knows everything you touch is going to make you sick? Well relax! According to Abigail Salyers, Ph.D., professor of microbiology at the University of Illinois in Urbana, under normal circumstances there is no reason to treat doorknobs and sinks as if they were coated in swine flu virus. She said, "Germs are ubiquitous, but fewer than 1% of them cause disease, and many actually keep us healthy." She went on to say, "Not only are most bugs benign, but it typically takes thousands, or even millions, of the bad ones to make you sick."
Viruses survive longer on hard surfaces so concentrate your cleaning efforts on those surfaces.
Note: Dr. Salyers said, "Under normal circumstances." When someone has a communicable illness, more stringent efforts apply.
