It's that time of year again. Flu season is upon us, marked by public health campaigns and reminders to get vaccinated.
Every year, up to 5 million people worldwide fall severely ill due to influenza (flu), resulting in about 250,000 to 500,000 deaths. In the United States alone, nearly 111 million workdays are lost every season due to the flu. That equals approximately $7 billion per year in sick days and lost productivity.
