Unfortunately, there is no quick cure for a cold or the flu. It just has to run its course. Either can last from a few days to more than a week. There are some ways, however, to reduce your likelihood of catching a virus, or lessen the symptoms once you have one, says Dr. Chappell. And I usually recommend that those who work or reside in healthcare facilities get a flu vaccine yearly.
Most treatment just relieves the symptoms.
Anti-inflammatories and Tylenol can help. Drinking lots of fluids and resting are extremely important. Those who work through their illness have longer recovery times. Dr. Chappell cautions about taking flu or the common cold too lightly. If the illness seems more severe or more prolonged than normal, it's probably wise to see a doctor for an evaluation.
