A simple mathematical model without seasonality indicated that the apparently chaotic dengue epidemics in Singapore have characteristics similar to epidemics resulting from chance. Randomness as a sufficient condition for patterns of dengue epidemics in equatorial regions calls into question existing explanations for dengue outbreaks there.

Influenza epidemics occur once a year during the winter in temperate areas. Little is known about the similarities between epidemics at different locations. We have analyzed pneumonia and influenza deaths from 1972 to 1997 in the United States, France, and Australia to examine the correlation over space and time between the three countries. We found a high correlation in both areas between Fran...

We consider a multitype epidemic model which is a natural extension of the randomised Reed-Frost epidemic model. The main result is the derivation of an asympotic Gaussian limit theorem for the final size of the epidemic. The method of proof is simpler, and more direct, than is used for similar results elsewhere in the epidemics literature. In particular, the results are specialised to epidemic...

Abstract This essay will examine two “graphic novel” depictions of WWI epidemics: one that depicts scientific advances during the dysentery epidemic on European front in World War One; and another Spanish influenza unfolding across United States America. Both texts narrativise an through a verbal visual engagement with historical discourses. These were produced within five years our current Cov...
