"The Impact of Flushing with the Toilet Lid Up or Down"
A study by microbiologist Charles Gerba and his team at the University of Arizona found that whether you flush the toilet with the lid open or closed makes little difference in preventing the spread of viral particles. The study, published in the American Journal of Infection Control, revealed that viral particles spread to the floor and nearby surfaces regardless of the lid position. The only effective way to reduce the spread of germs is to regularly disinfect the toilet, toilet water, and nearby surfaces. Other researchers suggest keeping the lid closed, routine use of disinfectants, hand washing, and avoiding handling personal items in the restroom to minimize exposure to germs.
