The timing of flu outbreaks vary each year, but in the U.S. it usually happens during the winter months. Doctors say that the minor epidemics usually take 3 weeks to peak and another 3 weeks to wind down, while individual cases only take a few days to come and go. The flu is the cause of around 36,000 deaths and 200,000 hospitalizations each year. It costs an estimated 10 billion dollars as well. It is said the flu virus never completely goes away, it just keeps getting passed from person to person and finally multiplies ten fold in the winter months. Some reasoning behind higher outbreaks in cold months is that people tend to stay indoors more during this time of the year and are in closer contact with people because of it. The flu strain also lingers longer on surfaces such as doorknobs, car steering wheels, etc...during the cold months. It is recommended to get a flu vaccination each year to prevent yourself from becoming sick. In general, just take good care of yourself and make sure you wash your hands regularly, especially if you want to stay out on the course.
