Lesson 1

  1. The main way that illnesses like colds and flu are spread is from person to person in respiratory droplets of coughs and sneezes known as droplet spread.

  2. The two main ways that germs are passed from person to person through droplet spread are:

  3. a. When droplets from a cough or sneeze of an infected person move through the air and are deposited on the mouth or nose of people nearby.
    b. When a person touches respiratory droplets from another person on a surface like a desk and then touches his or her own eyes, mouth or nose.

  4. Some viruses and bacteria can live two hours or longer on surfaces like cafeteria tables, doorknobs, and desks.

  5. The three main ways to stop droplet spread are to:

  6. a. Cover your mouth and nose when coughing or sneezing
    b. Clean your hands often
    c. Remind others to practice healthy habits.

  7. Teens need to get plenty of sleep and physical activity, drink water, and eat good food to help them stay healthy during the flue season.
