what is the difference between the flu and cold
What is the difference between a cold and the flu? The main difference between a cold and the flu is that the flu is caused by very different virus types than a cold. Flu symptoms tend to be much worse than cold symptoms, and they come on suddenly (cold symptoms, on the other hand, tend to arrive gradually).
It's important to know the difference between flu and cold symptoms. A cold is a milder respiratory illness than the flu. While cold symptoms can make you feel bad for a few days, flu symptoms can make you feel quite ill for a few days to weeks.
