It’s easy to be misled about the causes the flu or the cold (or the difference between them) with so many “wisdom gems” out there. There is a good chance some of the information you have may be wrong.
Both cold and flu are contagious viral infections of the respiratory tract that make you cough and give you headache. But congestion, sore throat, and sneezing are associated with colds, while the flu brings high fever for possibly days, tiredness, as your body feels weak and physically may hurt.
A cold is milder than the flu and one can’t turn into the other because they are caused by different viruses. Cold symptoms last for about 5-7 days while those of the flu can linger for several weeks. They include runny or stuffy nose, sneezing, coughing and the best way to avoid it is by practicing good hygiene. The flu, on the other hand, includes symptoms like shaking chills, dry coughing, fever, body aches and the best way to prevent it if by getting the flu vaccine.
The cold is called “common” for a reason. Approximately 22 million school days are lost each year in the U.S. due to the illness, according to the Centers for Disease Control and Prevention, and about 100 different viruses can cause it.
