What is the importance of studying epidemiology of communicable diseases?
When a disease occurs in a population, epidemiologists help us to understand where the disease is coming from, and who it is most likely to impact. The information gathered can then be used to control the spread of the disease and prevent future outbreaks.
What is epidemiology and disease?
Epidemiology is the foundation of public health and is defined as the study of the “distribution and determinants” of diseases or disorders within groups of people, and the development of knowledge on how to prevent and control them.
How are diseases spread in epidemiology?
In direct transmission, an infectious agent is transferred from a reservoir to a susceptible host by direct contact or droplet spread. Direct contact occurs through skin-to-skin contact, kissing, and sexual intercourse. Direct contact also refers to contact with soil or vegetation harboring infectious organisms.
What is the difference between infectious and communicable diseases?
So, what is a contagious disease? Recap time. Communicable diseases are infectious diseases. An infectious disease is contagious when it spreads through direct, bodily contact with an infected person, their discharges, or an object or surface they’ve contaminated.
What is the difference between communicable and non communicable disease?
Diseases are frequently referred to as communicable or non-communicable. Communicable diseases comprise infectious diseases such as tuberculosis and measles, while non-communicable diseases (NCDs) are mostly chronic diseases such as cardiovascular diseases, cancers, and diabetes.
Is Epidemiology the same as infectious disease?
Infectious disease epidemiology (which includes the epidemiology of viruses) is the study of the complex relationships among hosts and infectious agents. Epidemiologists are interested in virus spread or transmission, with or without disease.
What are infectious and noninfectious diseases?
Infectious diseases are transmitted from person-to-person through the transfer of a pathogen such as bacteria, viruses, fungi or parasites. A non-infectious disease cannot be transmitted through a pathogen and is caused by a variety of other circumstantial factors.
What are the most common communicable diseases?
What are the 10 most common infectious diseases?

What is the most communicable disease in the US?
Communicable Diseases Triggering The Most Worldwide Deaths. Communicable diseases like tuberculosis, HIV/AIDS, and hepatitis C are responsible for thousands of deaths worldwide each year. Health workers inspect specimens for the presence of infectious viral particles.
How do you prevent communicable diseases?
