According to a new study by the University of Arizona, when you go to work sick, your germs infect everyone and everything . . . FAST.

--If one person goes to work sick, the risk of their coworkers getting sick increases by between 40% and 90%.

--The researchers used artificial viruses to see how fast germs would spread in an office. And just one sick person managed to spread the virus to HALF the commonly-touched surfaces in the office, in just four hours.

--That included the coffee pot, desks, and elevator buttons.

--Which means if you go to work sick, you'll have spread it to half the office by lunch . . . and by the end of the day, 70% of the office surfaces will be contaminated by the virus.
