Flu season is upon us. With the recent outbreak of the H1N1 Virus ("Swine Flu") as well as the ever-present seasonal flu, employers must face increased absenteeism by their employees. Much like the regular flu, H1N1 causes fever, sore throat, nausea and fatigue. However, this particular strain of illness is predicted to be particularly dangerous not only for those with preexisting medical conditions such as asthma or diabetes, but also for those under the age of 25, as opposed to the elderly who are normally at highest risk of severe injury or death from the seasonal flu. This means that employers will likely see more of their younger employees affected by the H1N1 virus than from the regular flu.
