Is it cold or flu?

Flu and cold have similar symptoms, and can easily be confused. While both conditions are respiratory illnesses caused by viruses, cold is generally milder than flu. Though most people recover from flu in a week or more, in some cases flu can result in serious health complications that can lead to hospitalization or death.

The chart below may help you identify the likely cause of your symptoms. Your doctor can run special tests to definitively determine whether you are suffering from cold or flu.
