The single best way to prevent seasonal flu is to get vaccinated each year, but good health habits like covering your cough and washing your hands often can help stop the spread of germs and prevent respiratory illnesses like the flu. There also are flu antiviral drugs that can be used to treat and prevent flu.

1. Avoid close contact.

Avoid close contact with people who are sick. When you are sick, keep your distance from others to protect them from getting sick too.

2. Stay home when you are sick.

If possible, stay home from work, school, and errands when you are sick. This will help prevent spreading your illness to others.

3. Cover your mouth and nose.

Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick.

4. Clean your hands.

Washing your hands often will help protect you from germs. If soap and water are not available, use an alcohol-based hand rub.

5. Avoid touching your eyes, nose or mouth.

Germs are often spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth.

6. Practice other good health habits.

Clean and disinfect frequently touched surfaces at home, work or school, especially when someone is ill. Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids, and eat nutritious food.

Gastroenteritis precautions

The best way to prevent the spread of intestinal infections is to follow these precautions:

  • Get your child vaccinated. A vaccine against gastroenteritis caused by the rotavirus is available in some countries, including the United States. Given to children in the first year of life, the vaccine appears to be effective in preventing severe symptoms of this illness.
  • Wash your hands thoroughly. And make sure your children do, too. If your children are older, teach them to wash their hands, especially after using the toilet. It’s best to use warm water and soap and to rub hands vigorously for at least 20 seconds, remembering to wash around cuticles, beneath fingernails and in the creases of the hands. Then rinse thoroughly. Carry towelettes and hand sanitizer for times when soap and water aren’t available.
  • Use separate personal items around your home. Avoid sharing eating utensils, glasses and plates. Use separate towels in the bathroom.
  • Keep your distance. Avoid close contact with anyone who has the virus, if possible.
  • Disinfect hard surfaces. If someone in your home has viral gastroenteritis, disinfect hard surfaces, such as counters, faucets and doorknobs, with a mixture of two cups of bleach to one gallon of water.
  • Check out your child care center. Make sure the center has separate rooms for changing diapers and preparing or serving food. The room with the diaper-changing table should have a sink as well as a sanitary way to dispose of diapers.

Take precautions when traveling

When you’re traveling in other countries, you can become sick from contaminated food or water. You may be able to reduce your risk by following these tips:

  • Drink only well-sealed bottled or carbonated water.
  • Avoid ice cubes, because they may be made from contaminated water.
  • Use bottled water to brush your teeth.
  • Avoid raw food — including peeled fruits, raw vegetables and salads — that has been touched by human hands.
  • Avoid undercooked meat and fish.
