Question
we discussed how diseases like plague and rabies can spread in space by diffusion. Find a scientific journal article that describes a disease (NOT plague or rabies) that also seems to spread in space by diffusion (make sure to cite the study). (Note: if you cannot answer these questions with the paper you read, then find another paper) What does it mean for “a disease to spread in space by diffusion”?In your scientific paper, what is the disease, the host, and where is the disease spreading from and to?For your selected study that described the diffusion, what was the value of the parameter, D (units are distance/time)? Even if the study does not explicitly give D, you may be able to estimate it from the information provided in the paper or from maps. What are disease “sparks”? Did your paper describe any evidence of “sparks”?Inevitably diffusion waves of disease become disrupted. What accounts for the disruption of the wavefront for your disease?
Explanation / Answer
Disease diffusion refers to the variable spatial occurrence of ill health, such as the epidemics of infections, caused by the spread of disease agents through space and time.
