Abstract
The paper draws attention to the asymptomatic and mildly symptomatic cases of COVID-19, which, according to some reports, may constitute a large fraction of the infected individuals. These cases are often unreported and are not captured in the total number of confirmed cases communicated daily. On the one hand, this group may play a significant role in the spread of the infection, as asymptomatic cases are seldom detectedВ and quarantined. On the other hand, it may play a significant role in disease extinction by contributing to the development of sufficient herd immunity.
