Healthcare Science

UNIT TWO:

Safety Practices &

Infection Control

Modified by the CTAE Resource Network

January 2010


Standard

Students will demonstrate the proper implementation of safe work practices to prevent injury orillness.


Activities

  • Glogerm Demonstration – Student Volunteers

  • How Lou Got the Flu Data Gathering – Paired group

  • Chain of Infection Data Organization - Small group

  • Chain of Infection Application Game – Large group

  • Immune Platoon Internet Interactive Tutorial – Paired group


Catching the Ball Discussion

  • How effective was hand washing in removing germs from students’ hands?

  • Did germs continue to be passed from the ball to hands of other students throughout the activity?

  • What was the tally of catches for Student A?

  • What was the tally of catches for Student B?

    (We will use the number of catches later on in this infection control unit.)


UNIT TWO - SAFETY Objective

Upon completion of this lesson, you will be able to:

  • Identify the transfer of microbes from one person to another,

  • Demonstrate the single most effective way to decrease the spread of microbes.


How Lou Got the Flu Activity

  • Go to the American Museum of Natural History website at this address: www.amnh.org

  • Type in the search bar infection detection.

  • Click first result which says Infection Detection Protection

  • Click on How Lou Got the flu.


Objective

I will explain the spread of infection by organizing data gathered from How Lou Got the Flu and displaying this data in the Chain of Infection diagram.


Review

How Lou Got the Flu Data Gathering

First cycle done together:

Flu

Duck

Duck poops

Pigs sniff poop

Pigs have flu

** Now review all cycles in the transmission of flu to Lou.

Important Note!

  • The flu is not always transmitted from animals to people.

  • People can give animals the flu.

  • You can get the flu from your family’s pet not just farm animals.

Girl got the flu from the puppy.

Cat got the flu from the man.


Write a story

  • Write a story about how a person or animal got the flu.

  • Have the flu start in Russia and end in the state of Georgia.

  • Use the chain of infection in your story.


Wash your hands often because during our daily activities we encounter many different germs that can make us sick.


Breaking the Chain of Infection


What is the single most effective way to decrease the spread of harmful microbes (germs)?


Pretty women buy fancy nails!

What does that have to do with hand washing?

How Lou Got the Flu Written Assignment

Write a paragraph about the following topic:

Think of an example you have seen at school when germs are being spread. Apply what you have learned about the spread of infectious agents (germs) through the Chain of Infection. Describe how the spread of these germs could result in an infection. Include each link of the chain in your description.

Your paragraph must include a minimum of 10 sentences.


REVIEW - Draw the Chain of Infection and label the circles.
