Key Facts to Know about Flu

The influenza or flu virus is a highly contagious respiratory illness caused by several flu viruses. It spreads when a person with the flu coughs, sneezes or talks, causing droplets containing their germs to land in someone else’s mouth or nose. The virus can also live on surfaces and spread when someone touches it and then touches their own mouth, eyes or nose. It is estimated that between 5 to 20 percent of Americans get the flu each year.

Symptoms include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, fatigue and sometimes vomiting and diarrhea. These symptoms typically last one to two weeks.

Children younger than 5 years old, adults of 65 years or older, people with certain chronic health conditions and pregnant women are at high risk for getting sick with the flu.

According to the Centers for Disease Control and Prevention (CDC), people infected with the flu may be able to spread it to others starting one day before symptoms develop and up to five to seven days after being sick. Children and people with weakened immune systems, however, can have the virus present in their body for longer periods of time and are more prone to being contagious even after being sick. 

While it typically peaks in January or February, flu season starts as early as October. The best protection against the flu is the annual flu vaccination. Because it takes about two weeks for the vaccination to start protecting against the flu, everyone is encouraged to get vaccinated as soon as possible.

The vaccination is recommended for everyone six months and older. Caregivers are always advised to get the vaccination, but especially when around children who are under six months or children who have health conditions.

It is also important to remember that the flu vaccine cannot cause the flu.

In addition to getting the flu vaccine, the CDC recommends these routine preventive steps to help stop or slow the spread of infection during flu season:  
  • Cover coughs and sneezes with a tissue. Throw the tissue in the trash after using it.
  • Wash hands often with soap and water. If soap and water are not available, use an alcohol-based hand rub.
  • Avoid touching your eyes, nose and mouth.
  • If you or someone in your household is sick, limit contact with others as much as possible, and stay home for at least 24 hours after the fever is gone without the use of fever-reducing medicine.
  • Clean and disinfect surfaces and objects like bedside tables, bathroom surfaces, kitchen counters and toys.
