Most public washrooms are equipped with automatic hand-dryers (standard or jet dry ones). A new study has found out that high-speed jet dryers actually spread more viruses (up to 60 times) more that the standard air dryers and 1300 times more than the paper towels. So if one does a poor job in hand washing followed by using the 400 miles-per-hour (jet dry) hand dryers, the microbes from the hands spread in the dryer and consequently, the aerosols generated may also potentially spread in the washroom. If not for ourselves, but for others we need follow good hand washing procedures especially in the public washrooms.
