What is Public Health? (00:35)
The five pillars of public health are epidemiology, health services management, bio stats, health education, and health promotion.
A Good Example? (00:40)
COVID-19 exemplifies aspects of epidemiology and public health; infectious diseases are never completely gone.
Epidemiology Origins (02:49)
Hippocrates sought a logical relationship between disease and environmental influence; he coined the term epidemic. Pandemic examples include the Plague of Justinian, the Black Death, New World Smallpox, the Influenza Pandemic of 1918, HIV/AIDS, and COVID-19.
Combating Disease (02:54)
Variolation likely originated before 1700 by North African Arabs. Edward Jenner evolved the science to inoculation. Dr. John Snow’s study of the London cholera epidemic spurred public sanitation. Maj. Walter Reed and team discovered how malaria spread, implementing mosquito fumigation. Scientists used modern technology to combat COVD-19.
Epidemiology and Public Health Objective #1 (01:13)
Objective one includes identifying potential problems and developing prevention strategies. Rachael Nolan discusses public health versus medicine.
Epidemiology and Public Health Objective #2 (03:27)
Objective two includes conducting research and assessing risk. Experts discuss translational research and the hygiene hypothesis.
Epidemiology and Public Health Objective #3 (02:11)
Objective three includes analyzing data, developing models, and predicting outcomes. Learn several factors that influence methods.
Epidemiology and Public Health Objective #4 (02:28)
Objective four includes disseminating prevention strategies to the general public and heath care workers. Educational components must be tailored to the audience.
Epidemiology and Public Health Objective #5 (02:55)
Objective five includes influencing public policy makers to implement strategies that improve the health and wellbeing of the general public. This happened quickly with the COVID-19 pandemic, unlike with tobacco smoking.
The field of epidemiology is highly interdisciplinary. Divisions include molecular, environmental, disaster, forensic, travel, and occupational. Experts reflect on their work and importance of epidemiology.
