Colds & Flu

“I used to get colds often, especially around exam times. Now I make sure I wash my hands a lot. I think this helps me get fewer colds.”

Sylvia P., Brooklyn College

Colds and flu are the number 1 reason students miss class due to illness. Colds and flu are caused by viruses. Flu is short for influenza, a virus that affects your upper respiratory system. This includes your nose, throat, and lungs. “Stomach flu” is not influenza. Rather, it is stomach pain, diarrhea, vomiting, etc., caused by a virus in the stomach and intestines. For these symptoms, see “Abdominal Pain”, “Diarrhea”, and/or “Vomiting & Nausea.”

Is it a cold or is it the flu? See the chart below to learn the differences between the two.

Flu symptoms come on suddenly and affect the body all over. Cold symptoms mostly affect you above the neck. When you get the flu, you are also more prone to bronchitis, sinus, and ear infections.

Prevention

Wash your hands often. Keep them away from your nose, eyes, and mouth. Use an instant hand sanitizer when you can’t wash your hands.

	Try not to touch people or their things when they have a cold or the flu.
	Get regular exercise. Eat well. See “Eat Well & Get Regular Exercise”.
	Get adequate rest. See “Set Up Good Sleep Habits”.
	Get a flu shot each fall if your health care provider advises it.

Signs & Symptoms

Treatment

Self-care treats colds and most cases of the flu. Prescribed antiviral medicines, such as Relenza, Tamiflu, and rimantidine may make flu symptoms milder and help you recover sooner if started within 48 hours of the onset of flu symptoms.

Self-Care

	Drink lots of liquids.
	Take an over-the-counter medicine for muscle aches, and/or fever, but don’t take aspirin if you have flu-like symptoms. (See “OTC Medications”.)
	Use an over-the-counter saline nasal spray, such as Ocean brand. Use as directed on the label.
	Use a cool-mist vaporizer in your room.
	Have chicken soup. It helps clear mucus.
	Take echinacea, zinc lozenges, and/or vitamin C as advised by your health care provider, when cold or flu symptoms start. Don’t take echinacea and/or zinc lozenges long term. These do not prevent colds and flu.

For a Sore Throat:

	Gargle every few hours with a solution of 1/4 teaspoon of salt dissolved in 1/2 cup of warm water. Make sure the salt is dissolved.
	Drink tea with lemon (with or without honey).
	Suck on hard candy or a medicated lozenge.
