A Heterogeneous Branching Process with Immigration Modeling for COVID-19 Spreading in Local Communities in China

<div>The simulation results of the age-dependent branching process with immigration. The red, blue, and black curves are for the local infectees divided as Home, Social, and Secondary. Home and Social refer to the infected cases of the imported cases taking place at home and out of home, respectively. Secondary refers to the infectees caused by Home and Social. The nine subfigures are drawn with different combinations of the values for the testing parameters as <svg height="10.8844pt" id="M99" style="vertical-align:-1.5765pt" version="1.1"
