Flu shot

It's flu season in Baltimore.

A few days after Christmas, Baltimore resident Kathleen Dudley began experiencing telltale signs of the flu — fever, chills, body aches, sore throat, cough and overall exhaustion.

"The worst part — the fever and chills — lasted for about 24 hours," she says. "But the fatigue and cold symptoms lasted much longer."

According to the Maryland Department of Health and Mental Hygiene, between Oct. 1 and Jan. 5, 6,273 Marylanders tested positive for influenza; nearly 30 percent of those positive tests occurred during the week ending Jan. 5.

"According to the [Centers for Disease Control and Prevention], this year's flu season is among the highest in recent years," says Dr. Marc Leavey, an internal medicine physician with Lutherville Personal Physicians.

"The flu is a serious disease," he says. "Every year, thousands of people die from the flu. You can't shake off the flu, and if you've never had it, consider yourself lucky. But luck runs out."

For those who think it's too late for a shot or are holding onto other myths about the flu, we asked local experts to give us answers about how to prevent getting the influenza virus and what to do if you already have it. Hint: Chicken soup is good for more than the soul.

What are the basic steps I should take to avoid getting the flu?

"Get a flu shot, wash your hands and use common sense," says Leavey.

The flu vaccine is especially important for people at higher risk for flu complications. "If you have medical problems or are elderly or young, you are at higher risk for complications of the flu," says Dr. Joi Johnson-Weaver, a family medicine physician at GBMC at Perry Hall.

During this flu season in Maryland, 47 percent of people who have been hospitalized because of influenza were 65 or older.

Who should get the flu shot?

"The CDC recommends that everyone age 6 months and up should get the shot," says Johnson-Weaver.

Flu season typically begins in the fall and lasts through the spring. Though it is currently midseason, physicians stress that it is not too late to get the shot. "In fact, even if you have had the flu, the CDC recommends that you get a flu vaccine," says Leavey. The vaccine can still protect you from other strains of the disease.

However, people with certain conditions, including allergies, current febrile illness or a history of Guillain-Barre syndrome, may not be good candidates for the vaccine. If you have any doubts about whether you are an appropriate candidate, talk with your physician before getting the vaccine.

How do I get the flu shot?

"The easiest way," says Leavey, "is to ask your physician. The flu vaccine is normally covered by health insurance and Medicare, and there are free flu shot clinics throughout the area. You can check online or call your local health department for information."

Flu shots are also available at many pharmacies and through some employers.

What is the difference between the flu shot and the nasal-spray flu vaccine?

According to Johnson-Weaver, "The flu shot is an inactivated virus that is delivered via a shot. The flu mist is a weakened live virus given through a spray in the nose." Johnson-Weaver says the mist is more effective than the shot, but it is only appropriate for healthy, non-pregnant people between the ages of 2 and 49.
