What is the primary way to prevent the spread of infection?

Handwashing is considered the primary way to prevent the spread of infection because it effectively removes pathogens from the hands, which are a common route for transmitting germs. Proper hand hygiene disrupts the cycle of infection by ensuring that hands, which can easily come into contact with the eyes, mouth, and nose, are free from harmful microorganisms. Additionally, handwashing with soap and water can eliminate various infectious agents, including bacteria and viruses, thereby reducing the likelihood of infection.

While wearing masks can help reduce airborne transmission of respiratory infections, using disinfectants can sanitize surfaces, and avoiding contact can minimize exposure to infectious agents, handwashing stands out as a fundamental, universal practice that directly addresses the most effective measure in personal hygiene and public health. By establishing a routine of thorough handwashing, individuals contribute significantly to controlling the spread of infectious diseases.
