According to a study conducted by the University of Arizona, 9% of bacteria and viruses on surfaces are capable of causing infections in humans. The study found that these pathogens are responsible for a wide range of diseases, including colds, flu, and food poisoning.
The research team collected samples from a variety of common household surfaces, including door handles, light switches, countertops, and toilets. They then tested the samples for the presence of pathogenic bacteria and viruses.
Overall, the team found that 9% of the surfaces tested positive for pathogenic organisms. Door handles were the most likely to be contaminated (14%), followed by light switches (11%) and countertops (9%). Toilets were the least likely to be contaminated (3%).
While this may seem like a small percentage, it is important to remember that even a single bacterium or virus can cause an infection. And given that there are billions of surface areas in our homes and workplaces, it is not surprising that so many people fall ill each year from contact with contaminated surfaces.
There are some simple steps you can take to reduce your risk of becoming infected with a pathogen from a surface. First, clean all surfaces regularly with soap and water or disinfectant wipes. Second, avoid touching your face after coming into contact with a potentially contaminated surface. And third, wash your hands thoroughly with soap and water after using the restroom or handling food. By following these simple tips, you can help keep yourself healthy and safe from harmful bacteria and viruses
