THE EPIDEMIC.

ON THE STABILITY AND THRESHOLD ANALYSIS OF AN EPIDEMIC MODEL

We consider a mathematical model of epidemic spread  in which the  population  is partitioned  into five compartments of susceptible S(t), Infected I(t), Removed R(t), Prevented U(t) and the Controlled W(t). We assume each of the compartments comprises of cohorts of individuals which are  identical with respect to the disease status. We derive five systems of equations to represent each of the ...

The R0 Approach to Epidemic-non-Epidemic Phases Revisited

In this work, we revisit the basic reproduction rate R 0 definition for analysis of epidemic-non-epidemic phases describing the dynamics of the discrete stochastic version of the epidemic SIR model based on the Master Equation formalism. One shows that it is a very precise and efficient way to determine the epidemic threshold; using its most primitive concept, we can find exact results.

Epidemic$ and Pandemic$ are profitable?!

Forecasting the opioid epidemic.

S ince 2000, almost half a million Americans have died from drug overdoses. This modern plague— largely driven by opioid addiction—degrades health, saps productivity, spawns crime, and devastates families, all at enormous societal cost. How did we get here, and what do we do now? About 20 years ago, compassionate advocacy for better treatment of chronic pain, combined with aggressive marketing ...
