Preventing Influenza, Adult
Influenza, also known as the flu, is an infection caused by a germ called a virus. It affects your respiratory system, which includes your nose, throat, windpipe, and lungs. The flu causes cold symptoms, as well as a high fever and body aches.
The flu is contagious, which means it spreads easily from person to person. You're more likely to get it during flu season, which goes from December to March. You can get the flu by:
Breathing in droplets when an infected person coughs or sneezes.
Touching something that has the germs on it and then touching your mouth, nose, or eyes.

You work in health care.

What actions can I take to prevent the flu?
Lifestyle
Keep your body's immune system strong. To do this:
Do not use any products that contain nicotine or tobacco. These products include cigarettes, chewing tobacco, and vaping devices, such as e-cigarettes. If you need help quitting, ask your health care provider.
Medicines
Get a flu shot each year. It's the best way to prevent the flu.
Try to get the shot as soon as you can in the fall. But getting a flu shot in the winter or spring instead is still a good idea. Flu season can last into early spring.
You need to get a new flu shot each year. This is because the germs that cause the flu can change slightly from year to year.
If you get the flu after you get the shot, the shot can make your illness shorter and milder. It can also stop you from getting other serious infections caused by the flu.
If you're pregnant, you can and should get a flu shot.
Check with your provider before getting a flu shot if you've had a reaction to the shot in the past.
You may be able to get the vaccine as a nasal spray instead. But the nasal spray may not work as well as the shot. Check with your provider if you have questions about this.
Most people who have the flu get better by resting at home and drinking lots of fluids. But a medicine called an antiviral may lessen your symptoms and make the flu go away faster.
General information
