How Does Flu Spread?

People with flu can spread it to others up to about 6 feet away. Influenza mainly spreads through:

  • Droplets when an infected person coughs or sneezes, or talks. These droplets can  land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
  • Touching a surface or an object that has flu virus on it and then touching their own mouth, eyes or possibly their nose.

You may be able to pass on the flu to someone else before else before you know you are sick,as well as while you are sick. Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for an even longer time.Therefore, prevention from getting infected by influenza and spreading the virus is important.

Who Should Get Vaccinated?

The centers for disease control and prevention (CDC) in the U.S. recommends that everyone 6 months of age and older should get a flu vaccination.

Vaccination to prevent influenza is particularly important for people who are at high risk of serious complications from influenza;

  • Children aged from 6 months to 59 months
  • Elderly 50 years of age and above
  • Healthcare providers
  • Those who have chronic disorder.
  • Those who are extremely obese(BMI>40)
  • Women who are,or planning to be, pregnant.

Your best defence against the flu is to get vaccinated every year.
