Fomites are inanimate objects or surfaces that can carry and transmit infectious agents, such as bacteria and viruses. Common examples of fomites include doorknobs, light switches, and shared electronics. When a person touches these surfaces after an infected individual, they can pick up pathogens and potentially become ill. Preventing the spread of infections often involves cleaning and disinfecting fomites regularly. This is especially important in public places like schools and hospitals, where the risk of transmission is higher. By maintaining good hygiene practices, such as washing hands frequently, individuals can reduce the likelihood of illness caused by fomites.
