Final answer:
Epidemiology focuses on the study and control of health problems. John Snow was a key figure in establishing epidemiology as a scientific discipline through his work during a cholera outbreak. It is false that acute diseases are always less dangerous than chronic diseases; the severity depends on various factors.
Step-by-step explanation:
What is the Focus of Epidemiology?
The focus of epidemiology is the study of the distribution and determinants of health-related states or events in specific populations, and the application of this study to control health problems. Epidemiological research is applied to understand the cause of disease, identify trends in disease occurrence, and evaluate the effectiveness of medical and public health interventions. Applications include public health surveillance, outbreak investigation, and the study of disease natural history.
Who was John Snow?
John Snow was a British physician considered one of the fathers of modern epidemiology. His significance lies in his work during the 1854 cholera outbreak in London. Snow's mapping of cholera cases led to the identification of a contaminated water pump as the source of the outbreak, demonstrating the importance of epidemiological approaches in understanding disease spread.
Acute vs. Chronic Diseases - True or False
True or False: Acute diseases are always less dangerous than chronic diseases. False. The severity of acute diseases can vary widely, and some can be life-threatening or lead to significant disability, while many chronic diseases can be managed with ongoing treatment. Disease danger is not determined solely by whether a condition is acute or chronic.
