All workers should be advised to stay at home if they are unwell for at least 24 hours after their fever has subsided without the use of fever-reducing medications or after their symptoms have improved (at least 4-5 days after flu symptoms started). Workers who do not comply may expose themselves and others to serious health consequences. A person's body temperature ranges from 98.6 degrees Fahrenheit to 100.4 degrees F (37.0 degrees C to 38.0 degrees C). A fever is defined as a temperature of 100.4 degrees F or higher. However, many people feel fine with temperatures as low as 99.0 degrees F (37.4 degrees C). A person with a fever is more likely to experience problems including headache, nausea, vomiting, diarrhea, fatigue, irritability, and confusion. In most cases, there is no need to take action unless your worker's fever remains above 100.4 degrees F for more than 24 hours. Then you should consult your worker's doctor if they appear sick. Your employer should provide any necessary medical attention if you report symptoms of illness in your workplace. Yes, but it depends on how long you've had it. If you went to work while you were still feeling ill and your temperature is still elevated, this could put other people at risk of contracting influenza.
