### Lesson 8: What can Reduce the Spread of Influenza?

Influenza, commonly called the flu, is a viral infection that is highly contagious. A variety of methods have been proposed to reduce the spread of flu throughout a school. Can you determine which method works the best at reducing the infection rate? Get ready to stop the spread!

### Doing the science

- Start the Flu Transmission Simulation by clicking on the “Simulation” tab.
- Select the “None” button under the Factor menu on the left-bottom of the screen.
- Select the “Run” button at the bottom center of the screen.
- Note the Progress bar, which shows time running for a six-week period.
- Count and record in Table 1 the number of infected students at the end of the six weeks of the flu outbreak.
- Select the “Hand Washing” button under the Factor menu.
- Repeat steps 3 - 5.
- Select the “Sanitizer Station” button under the Factor menu.
- Repeat steps 3 - 5.
- Repeat these steps for the last three factors: Antibiotics, Masks, and Quarantining.
- Calculate the percentage of infected students out of the total population. To complete this calculation, divide the total number of infected students at the end of week 6 by 120 (the total population of students in the school). Multiply this value by 100 to convert it to a percentage. Enter these data into Table 1.
