Flu season is coming.

The flu vaccine and preventive measures like proper hand hygiene are the best defenses for protecting yourself from the many, many strains of flu. Sometimes, that pesky bug gets through anyway, though.

If you have a fever, cough and headache you cant shake, it may be the flu. Stay home, get some rest, use over-the-counter fever-reducing medication and up your fluid intake. Call a doctor if those methods arent doing the trick.

But how long will you be contagious, you wonder? And when do you start being contagious? We talked with infectious disease doctor Sherif Mossad, MD, about flu contagion and how to keep from sharing your flu germs.

The Centers for Disease Control and Prevention (CDC) says the time between being exposed to the flu and when you show symptoms is usually about two days. The clock starts ticking on your ability to infect others before your symptoms even appear, though.

You can spread the flu to others even before you know youre sick, Dr. Mossad says. You can be contagious with the flu beginning about a day before you feel symptoms. Youll be most contagious with the flu for the first three or four days after you actually feel sick. Thats why keeping your distance as much as possible for several days is important.

You may continue to be infectious for a week after your symptoms start. Children and adults with weakened immune systems may be contagious even longer.

Dr. Mossad says that after recovering from the flu, your timeframe for returning to normal work and school activities may depend on your job and how frequently you interact with people. Some schools and workplaces have specific guidelines for when you can return to work after the flu or other sicknesses. Check with your employer for any specific procedures.

But a good rule of thumb, Dr. Mossad says, is to stay home until youve been fever-free for at least 24 hours, without using fever-reducing medications, like acetaminophen (Tylenol).

A fever is defined as:

You should also stay home if you have other severe symptoms, such as a non-stop cough or shortness of breath.

The flu is considered a highly contagious disease. According to the CDC, the flu can circulate to others up to about 6 feet away.

And, some people can be infected with the flu without showing symptoms. Research shows that about 8% of the U.S. population gets sick from flu each season. When counting those who are carrying the virus without feeling sick, its believed that infection rates are closer to about 20% of the population. Even if you dont show flu symptoms, you still can spread it to others.

Dr. Mossad explains that the flu spreads when tiny droplets of virus-laden particles are exchanged between people.

The main way people can infect each other with flu is being in close proximity of each other, he adds. The infected person coughs or sneezes and tiny drops of their fluids get on my face or hands, or they land on the table were sharing. Then I touch my nose or my mouth, and now those virus-filled particles are in me.

By the next day, you can start passing the flu to others. The day after that, you may start feeling ill yourself.

To keep healthy this flu season, Dr. Mossad suggests a multi-pronged approach to flu prevention.

The CDC says the first and most important step in preventing flu is to get a flu vaccine each year.

The flu shot is your best defense against the flu, Dr. Mossad stresses. Studies tell us that if you get the flu vaccine, you are much less likely to have a severe illness and much less likely to be hospitalized.

Research shows that, whether you realize it or not, you probably touch your face an average of 23 times each hour. Imagine all the things youve touched since the last time you washed your hands. Now youre about to use those hands to rub your eyes. And chances are, without thinking about it, youre going to do it again in about two minutes.

Washing your hands is the No. 1 way to keep viruses from elbowing their way into your body and making you sick.

Make sure you wash your hands:

Wash your hands thoroughly for about 20 seconds with soap and water. If you arent able to use soap and water, use an alcohol-based hand sanitizer.

Limit your opportunities for infection by:

The flu is a tricky virus that can find its way in, even for the most vigilant among us. If youre sick and think its the flu, keep your distance to keep it to yourself. Know, too, that symptoms of the flu and symptoms of COVID-19 are easily confused. If you think you may be infected with either virus, call a healthcare provider early on. Early treatment equals better results.

There are medications your doctor can give you to help lessen the effects of the flu, Dr. Mossad says. In order for them to work, youll want to talk with your doctor early. If you wait it out a few days, chances are youll already be through the worst of your symptoms anyway, so the medication isnt going to be as helpful at that point.
