Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), first emerged in December 2019 in Wuhan, China, and spread rapidly across the world. In Oman, the first imported case was diagnosed on 24 February 2020 (Wahaibi et al., 2020). Until mid-August 2020, there was ongoing community transmission, with a total of 79,701 confirmed cases of SARS-CoV-2 infection and 488 deaths in Oman. The estimated number of infected individuals based on a national sero-survey for the same time period was 507,256, which indicates a case fatality rate (fraction of deaths among infected cases) of 0.1% (Oman News Agency, 2020).
