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

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.

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.”

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).

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).

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.

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

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

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

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
