WORDS OF THE WEEK – From standard epidemiology textbooks and from comments by Drs. Fauci and Birx, we have the several new terms. Many of the terms involve “constants,” which in every model and are always approximated at the on set. Even the constant of gravity. All the so-called models you hear about involve these constants, and that is why early models are often inaccurate. SIR model - Susceptible (those who can get it)-Infected (those who got it) -Removed (those who recovered). The SIR model is an equation that links these quantities. Important is there are constants of proportion for each disease most difficult to determine and usually approximated early in the epidemic (as we have sadly seen with COVID). Epidemics - are commonly associated with acute, highly-transmissible directly transmitted pathogens that either kills its host or induce strong protective immunity. Reproductive number R_0, average number of those newly infected from someone already infected Effect
