2. The Flu
The flu is caused by the influenza virus. It is among the most common of all disease and most people will catch it at least once in their lives. It is a seasonal disease and can be found throughout much of the world. There is a vaccine, and the flu is rarely dangerous, but vulnerable people need to be especially careful.
Not everybody that gets the flu will have symptoms and, of those that do, most will experience only mild symptoms. When symptoms do arise, they tend to include a fever, chills, and aching joints and bones. It can also cause Bell’s palsy in some cases.
