The typical employee’s desk has more bacteria per square centimeter than an office toilet seat. Desks, phones and other private surfaces are also prime habitats for the viruses and bacteria that cause colds, the flu, strep throat, pneumonia and other illnesses. Ewwwww.

Even if you keep your desk tidy, it may not be clean. Unlike toilets—which tend to be cleaned regularly—keyboards, phone receivers and desks rarely receive a wipe-down. Consider this: Crumbs and coffee spills are capable of supporting mini ecosystems. Without a cleaning, even a small area on your desk or phone can sustain millions of bacteria that could potentially cause illness.

The good news:

Heightened awareness and hygiene efforts can go a long way in keeping your office clean. Regular cleaning of personal and shared work spaces is essential in maintaining sanitary safety. Germ-busting in the office is a team effort, so make sure everyone gets involved.
