1. Counting Disease: Worldwide Importance of Certain Diseases
LESSON OBJECTIVES:
Understand Epidemiology and Infectious Disease
Discuss the global impact of three diseases of Malaria, HIV/AIDS and TB

2. WHAT IS EPIDEMIOLOGY?
Epidemiology is the study of the incidence (number of cases) of disease and pattern of a disease with a view to finding the means of preventing or controlling it.

3. DID YOU KNOW?
The word epidemiology comes from three Greek root words: Epi—means “on, upon, befall” (think of epidermis—“upon the body”) Demo—means “people” (think of demographics—“the study of statistics
of populations”) -ology—means “the study of”
So Epidemiology is literally defined as “the study of that which befalls people.”

4. EPIDEMIOLICAL PROFILE
Diseases or Medical Conditions that I have had
Diseases or Medical Conditions that my parents, my grandparents or any of my friends have had
Diseases I’ve Heard About
THIS ACTIVITY WILL TAKE 15 MINUTES

5. Epidemiology is concerned with:
Morbidity of a disease – the number of people currently living in the diseased state.
Mortality of a disease – the number of people who die from a specific disease (within a time frame).

6. COMMON INFECTIOUS DISEASES
Infectious diseases are diseases caused by microbes and that spread. The reason for most sick days for both kids and teachers is an infectious disease. There are many, from the common cold, ear infections, tonsillitis, and the flu (influenza) to pneumonia and mononucleosis.
The most common infectious disease-causing microbes are bacteria, viruses, fungi, and protozoa (a type of parasite).

7. HOW DISEASE SPREADS
The diseases may be passed from person to person (for example, if someone coughs or sneezes on another person). Sometimes, the disease is passed through another medium, for example, by drinking water or eating food infected with bacteria or through an animal carrier.

8. Infectious Disease
3 min

9. Malaria - Epidemiology
300 million people are affected
3 million people die each year from malaria
Disease restricted to tropical regions where Anopheles mosquito survives
Potential risk of disease spreading due to climate change

10. Tuberculosis - Epidemiology
One third of the world’s population carry the bacteria
Of that 10-15% go on to display symptoms
Just under 2 million people a year die of the disease
Asia, Sub-Saharan Africa & Eastern Europe are the most prevalent areas

11. HIV/AIDS Epidemiology
Rapidly spreading pandemic
Numbers infected unclear but could be near 50 million (almost 50% in Africa)
Over 2 million die each year from it
Spreading quickly in China & Russia

12. Your Task
You are going to research a disease, and present it to our class. We will pick the disease by table group randomly.
You will use your rubric, THE DISEASE AND CELL PROJECT MAP (page ---) and your GRADING RUBRIC (page ---)
Diseases Assigned Are:
CANCER, TB, HIV/AIDS, SICKLE CELL DISEASE, CYSTIC FIBROSIS, INFLUENZA (FLU), ASTHMA, ALZHEIMERS, DIABETES, SYPHYLIS
Research and collect referenced/validated data.
Be prepared to present your research on November 12-19cin front of the class
and hand in your report for marking

Established in 1948
HQ in Geneva, Switzerland
Exists to promote good health for all people on Earth and combat infectious diseases
Successes include official declaration of eradication of small pox in 1980
Currently aiming to eliminate polio in next few years
