When you have a cold, you may have a runny or stuffy nose, sneezing, a cough, a sore throat, and a low fever. Viruses cause colds. Antibiotics don't work against viruses, so they can't treat colds. An antibiotic will not make you feel better, help you get better faster, or prevent the spread of a cold.
It takes 1–2 weeks for a cold to go away. There are things you can do to feel more comfortable while you get better.

How do colds spread to others? Colds can spread when:
- A person with a cold coughs and/or sneezes the virus into the air, and someone else breathes it in.
- A virus gets in the eyes, nose, or mouth. This can happen by touching someone who has a cold, or by touching a hard surface (like a doorknob) that has the virus on it, and then touching your eyes, mouth, or nose.
How can I avoid getting colds? To protect yourself, your family, and others from colds:
- Wash your hands well and often using soap and water. Scrub for at least 20 seconds, then rinse and dry thoroughly. This is important after coughing or sneezing, and before and after eating. If soap and water are not available, use a hand sanitizer with at least 60 percent alcohol.
- Exercising regularly, eating a balanced diet, and getting the rest you need can help your immune system fight colds and other infections.
