During the winter months, hundreds of thousands of people will catch the influenza virus, a respiratory infection marked by these symptoms:
- Fever or chills
- Sore throat
- Runny nose
- Vomiting and diarrhea (more common in children than adults)
Most people recover from the flu in as little as a few days or as long as a couple of weeks, but for some groups, the flu can lead to serious complications. It can be life-threatening for infants under 6 months of age, people who are 50 to 75 years old, and people who have chronic health problems (like asthma, diabetes or heart disease) or compromised immune systems. “Complications from flu can be mild, such as sinus or ear infections, or more severe,” says Jeffrey Fein, D.O., board certified in internal medicine. “Pneumonia and inflammation of the heart or brain can be very serious and require the patient be hospitalized.”
Flu Shot Is the Best Defense
The best thing to do is make sure that all members of your family who are at least six months old have a flu shot this year. This vaccination stimulates your body’s immune system to make antibodies that can fight the virus if you are exposed to it later.
Unlike other vaccinations, such as those for polio or measles, people need to have a flu shot annually. This is because every year, there are different strains that cause influenza in the population. The flu shot you receive this year will guard against the three or four strains that doctors predict will be most prevalent in the 2019–2020 flu season.
“There are certain people that might need to look into other options for their flu vaccine,” says Jasmine Baez, M.D., an internal medicine doctor. “Those who have a severe allergy to eggs or who have had a bad reaction to the flu shot previously should speak to their doctor about whether the nasal flu vaccine might be a better choice.”
Other Ways to Fight the Flu
Unfortunately, even the flu shot isn’t 100 percent effective. Sometimes a different strain of the virus appears or you might be exposed to the flu before your shot establishes immunity. Take these commonsense actions to help limit spreading the flu:
- Wash your hands frequently.
- Cover your mouth and nose with a tissue or the crook of your arm when your sneeze or cough.
- Avoid crowds during the peak flu season.
- If you do get sick, stay home for 24 hours after your fever passes.
There are also medications that can help people who contract the flu. “Antiviral medications may be recommended for people who have a high risk of developing complications,” says Lauren Parkes, D.O., board certified in family medicine. “Because they disrupt functions of the virus itself, they can reduce the duration of the disease, as well as limit spreading it to others.” These benefits are most effective when the medication is taken shortly after flu symptoms first appear, within 48 hours. People with high risk of complications should see their doctor as soon as possible if they suspect they have the flu.
