If you’re not prepared for the flu, your health care provider may suggest getting tested for the virus, especially if you’re younger than 18.

It can be a lifesaving measure if you’ve had symptoms or a rash.

But you may also want to take precautions to protect yourself against catching the virus and the bacteria that produce it, especially in older people.

Here are some ways to protect your home, work and family from the flu.

Get tested: Make sure you have the right vaccines to prevent the flu and protect your body against getting the flu if you do get the flu or your flu symptoms worsen.

If you don’t have enough vaccine to protect you from the virus or you’re sick or in a nursing home, you may need to get a booster.

You may need a second dose of vaccine in order to avoid spreading the infection.
