1. Flu season is between October and May.

Some people get seasonal flu as early as October, with infections continuing through May.
2. The flu is contagious before symptoms start.
Highly contagious partly because it’s possible to pass the virus on before you become sick. According to the Centers for Disease Control and Prevention (CDC). You can infect someone with the virus one day before your symptoms start.
You’re most contagious within the first three to four days of becoming ill. Although you may remain contagious for up to five to seven days after you become sick.
It’s important to avoid close contact with others to prevent passing the illness to another person.
3. Symptoms can start abruptly.
The onset of symptoms can happen rapidly. You may feel fine one day, and be unable to do anything one or two days later due to your symptoms.
Sometimes, the onset of symptoms occurs as early as one day after exposure. In other cases, some people don’t show symptoms until four days after exposure to the virus.
4. It takes up to two weeks for the flu vaccine to work.
Getting a seasonal vaccine is one of the best ways to protect yourself against the influenza virus.
But it’s important that you get your shot early in the season. The flu shot is effective because it helps your body develop antibodies to protect itself against the virus. It takes about two weeks for these antibodies to develop, though.
If you’re exposed to the virus within two weeks of getting a vaccine, you may still get sick. The CDC recommends getting a vaccine by the end of October.
