Craig S. Carlson, David M. Rubin, Vilma Heikkilä, Michiel Postema
2021 Zenodo  
Accurately modelling the susceptibility, infection, and recovery of populations with regards to the COVID-19 pandemic is highly relevant for the implementation of counter- measures by governing bodies.  ...  The average transmission and recovery parameters were computed to be 0.33 week^{−1} and 0.23 week^{−1} , respectively.  ...  We demonstrate that the extraction of transmission and recovery parameters from real SIR data is feasible for an adaptive global system dynamics model of the COVID-19 pandemic.  ...

Dynamics of Interacting Hotspots – I [article]

Suman Dutta
2020 arXiv   pre-print
The worldwide spread of COVID-19 has called for fast advancement of new modelling strategies to estimate its unprecedented spread.  ...  Although each stochastic exchange conserves populations pair-wise, the disorder drives the global system towards newer routes to dynamic equilibrium.  ...  Since an effective model requires the prior knowledge of transmission and recovery rates, it is almost impossible to estimate them in the midway of an epidemic, for the rates depend on the nature of instantaneous  ...
