How often should high-touch surfaces be sanitized in facilities?

High-touch surfaces should be sanitized multiple times a day, especially during outbreaks of illness, because these areas are frequently contacted by individuals and can easily become contaminated with pathogens. Regular sanitization reduces the risk of germ transmission and helps maintain a safe environment, especially in places such as healthcare facilities, schools, and public areas where the spread of infections can have serious consequences. During an outbreak, increased frequency in cleaning and sanitizing these surfaces is crucial to control the spread of illness and protect public health.

The other options suggest less frequent sanitization, which may not be adequate in preventing pathogen transmission, particularly in high-traffic areas. Regular and thorough sanitization is a key practice in infection control protocols.
