Cyclical Student Shifting Models in the time of COVID-19

The codes simulate the 32 cyclical student shifting models as Non-Pharmaceutical Intervention (NPI) for in-campus face-to-face classes.

See the paper: https://www.medrxiv.org/content/10.1101/2022.08.09.22278587v1

The files SEIRSModels.m and SEIRSModels1.m contains the code to simulate the SEIRS model

where and are models of physical distancing and personal protection, respectively, and each of the cyclical shifting models is described by the function. Moreover, are the usual transmission, incubation and recovery parameters, and δ is the reinfection parameter. The simulation is implemented n times over uniformly distributed parameters (except for intial exposed inividuals which is Poisson distributed) with via Euler's method.

SEIRSControl.m file contains the initial values and parameters of the model while the files Compute1.m, Compute2.m and Compute3.m compute for the average daily incidence, Pearson R and the average 7-day incidence rates (IRs) depending on the the values of and .
