The CDC considers a fever a measured temperature of 100.4° F (38° C) or greater. In fact, all employees should stay home if they are sick until 24 hours after their fever is gone. 2 Taking this precaution is important not only for your own recovery, but also for the health of those around you at your workplace. The CDC also recommends that if you suspect you have the flu, or it has been confirmed but you do not have a fever, you should still stay home from work for four to five days after the onset of your symptoms. This is because you are most contagious during the first three days of the illness. 2 If someone at home is sick and you are not, however, going into work is acceptable as long as you monitor your health during this time. 2 With these factors in mind, monitor your symptoms and make sure to stay home if you're sick.
