Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


In a typical epidemic like COVID-19, infected individuals are contagious over a certain time span τ before they get immunized either by recovering or dying. During this contagion period which for COVID-19 typically ranges between one and two weeks, an infected individual can infect other individuals. When more individuals are infected than recover, the net reproductive ratio is greater than one and the epidemic spre; otherwise, it tends to die out.
