Differentiate the terms in each of the following pairs:

a. etiology and pathogenesis

b. infection and disease

c. communicable disease and noncommunicable disease

Accepted Answer

Hi, everyone. Our next question says which of the following is correctly described as the origin or source of a disease. A epidemiology. B etiology, C pathogenesis or D infection. So when we are talking about specifically a noun saying what is the source or what is the cause of a disease? The word we want is choice B etiology. You might hear it uses an adjective. For example, you might say the ideological agent of malaria is the plasmodium protozoa. So that's the word we're looking for. You might have been tempted to choose pathogenesis, especially seeing that root word genesis makes us think of a beginning. But pathogenesis is the study of or the process by which infection by some sort of infectious agent leads to disease. So while etiology specifically says this specific thing is the cause of this particular disease pathogenesis says how do we go from the mosquito biting you and you get the plasmodium inside your body from two. Now you have malaria with all its symptoms and you might spread it to other people when you're bitten by a mosquito. So, pathogenesis is a larger picture of this process of going from the etiology of our disease to actually having the disease, all the symptoms. So it would include steps like implantation of the virus upon its area of entry, uh local replication of the virus where it entered spread to target organs and then how does it shed to the environment? So this whole process along the way. So it's not our correct answer. Then choice. A epidemiology, that's even broader epidemiology is that general study of disease, how it's distributed, its causes determinants of disease and health and populations and prevention of disease. So it can encompass uh medicine, research, public health, public policy. Um so very large, very broad. So looking for the etiology of the disease would be part of the study of epidemiology, but it's not just the cause of a disease. And then finally, choice d infection. Um again, you might be a little tempted to choose this as, oh you get infected with something but infection is too broad. A term infection would just refer to the invasion and growth of germs in the body. And these germs could be bacteria, viruses, yeast, fungi, other microorganisms. So infection is sort of the general term for this happening. Whereas etiology is looking for the specific source, the specific micro organism, that's the cause of a particular disease. So that's why infection isn't the right answer for us. So again, the origin or source of a disease would be described by the term choice B etiology. See you in the next video.
