What causes colds and the flu?
Viruses. Over 100 different viruses can cause colds. There aren’t as many viruses that cause the flu. That’s why there’s a shot for the flu and not for colds.
What can you do to feel better?
There’s no cure for a cold or the flu. Antibiotics don’t work against viruses. All you can do to feel better is treat your symptoms while your body fights off the virus (see below).
Ways to treat your cold/flu symptoms
- Stay home and rest, especially while you have a fever.
- Stop smoking and avoid secondhand smoke, which can make cold symptoms worse.
- Drink plenty of fluids like water, fruit juices and clear soups. Fluids help loosen mucus. Fluids are also important if you have a fever because fever can dry up your body’s fluids, which can lead to dehydration.
- Don’t drink alcohol.
- Gargle with warm salt water a few times a day to relieve a sore throat. Throat sprays or lozenges may also help relieve the pain.
- Use saline (salt water) nose drops to help loosen mucus and moisten the tender skin in your nose.
Should you take medicine for a cold or the flu?
No medicine can cure a cold or the flu. Medicine can, however, help relieve some of your cold or flu symptoms. Check with your doctor before giving any medicine to children.
