CDC recommends that employees who have symptoms of acute respiratory illness stay home and not come to work until they are free of fever (100.4° F / 37.8° C) or greater using an oral thermometer), signs of a fever, and any other symptoms for at least 24 hours, without the use of fever-reducing or other symptom-altering medicines (e.g. cough suppressants). Employees should notify their supervisor and stay home if they are sick. We recommend that businesses review CDC’s interim guidance for businesses and employers for planning and responding to coronavirus disease.
