Influenza is a contagious virus that gets spread around fast. The flu is caused by the influenza virus. It can sometimes cause very severe illnesses, can cause a person to be hospitalized, and can even cause death. Babies, older people, and people with severe health conditions are at high risks. Each year millions of people get sick with this flu.
People sometimes get influenza mixed up with the stomach flu. The stomach flu is called gastroenteritis. They are two different things.
The symptoms of the flu are: having a high fever, coughing, sore throat, runny or stuffy nose, body sore, and muscle aches. Headaches and vomiting a lot are also possible signs of the flu. Also, little kids may have diarrhea.
People can sometimes not tell the difference between the flu or a cold. A cold comes in slowly and is less severe. Colds often just cause headaches, fevers, and a runny nose. Influenza is way more severe then a typical cold.
The flu can cause other illnesses such as: bronchitis, ear infections, sinus infections, and pneumonia. Many people with the flu recover on their own without any medications, but if anybody is diagnosed with the flu they need to stay home and not go around anybody else.
If you have high symptoms of the flu you should reach out to a health care provider. The best way to prevent the flu is to get a flu shot every year.
