When you're feeling sick, it's hard to know whether you just have a bad cold, or if you have the flu. Even if you do have the flu, there's often little you can do but go to bed, drink fluids, and take over-the-counter medications to help you feel better. Prescription flu-specific medications are available but they only reduce, by about one day, the length of time your flu will last. Furthermore, they must be started within 48 hours of the onset of your symptoms. Usually these medications are best used for persons with other serious illnesses who are at risk of developing complications from the flu. You should consult with a health care provider to see if taking one of these is right for you.
A self assessment to help you know whether or not you have the flu has been developed by Dr. Keith Williamson, Director of Health Services at Midwestern University, who has given us permission to use it.
