1.Flu: Comes on Fast and Furious
If you feel like you’ve been hit by a truck, it’s probably the flu. Symptoms like sore throat, fever, headache, muscle aches, congestion, and cough tend to come on suddenly. Colds are usually less intense and include a runny or stuffy nose. The flu gets better over 2 to 5 days, but you might feel run-down for a week or longer. Colds come on slowly and last up to 10 days.
2.Fever: Usually Means Flu
While some people may get a slight fever when they have a cold, most don’t. If you have the flu, you’ll probably run a temperature of 100-104 F. Children’s flu fevers tend to be higher. Kids may also be more likely to have a fever with the common cold.
