How to determine the difference between the cold and the flu?

Both the cold and flu are caused by viruses and don't need antibiotics in order to be cured.

Symptoms are usually felt for 7-10 days. A runny nose, cough and congestion are expected. Look out for a fever, though. If you're developing one, chances are, you have the flu.

Antiviral medication can be used to help reduce flu symptoms, if you catch it within 48 hours.
