The seasonal flu vaccine protects against the influenza viruses that research indicates will be most common during the upcoming season. There are several flu vaccine options this flu season.
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 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, nose.
Cover your mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick. Flu and other serious respiratory illnesses, like respiratory syncytial virus, or RSV, whooping cough and severe acute respiratory syndrome, or SARS, are spread by cough, sneezing or unclean hands.
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.
