A warning has been issued by the Centers for Disease Control (CDC) in Taiwan concerning the spread of severe complicated influenza (SCI) and the need for vaccinations before the onset of winter. SCI arises where patients already suffer from another underlying health condition. In one recent case a 36-year old man died only one day after flu had been diagnosed. Employers that identify the possible incidence of flu in employees should send them home immediately and advise them to avoid contact, particularly with elderly people.
