Linking asymptomatic case characteristics with the epidemic potential of coronavirus-like outbreaks Joshua S. Weitz Biological Sciences, Physics Georgia Tech 2020 MIT License
MATLAB code to generate heatmaps quantifying the relevance of asymptomatic transmission given variation in relative transmission and probability that a given, newly infected individual is asymptomatic. The code is based on a SEIR-variant with asymptomatic and symptomatic classes.
\begin{eqnarray} \dot{S}&=&-\beta_a S I_a -\beta_s S I_s \ \dot{E}&=&\beta_a S I_a +\beta_s S I_s -\gamma_e E\ \dot{I}_a&=&p\gamma_e E-\gamma_a I_a\ \dot{I}_s&=&(1-p)\gamma_e E-\gamma_s I_s\ \dot{R}&=&\gamma_a I_a + (1-f)\gamma_s I_s \ \dot{D}&=&f\gamma_s I_s. \end{eqnarray}
