Coronavirus (COVID-19) Collection
- Coronavirus disease 2019 (COVID-19) is a severe, acute respiratory syndrome caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). It was first identified in Wuhan, China in December 2019 (Huang et al., 2020; Zhu et al., 2020), and within months had spread to most nations of the world (Hick and Biddinger, 2020; World Health Organization, 2021).
- The emergence of SARS-CoV-2 (causing COVID-19) in December 2019 rapidly evolved into a pandemic, with cumulative numbers of more than 83 million confirmed cases and 1.8 million deaths globally according to WHO (2021a). During the lengthy course of this pandemic, The Lancet (2020) reported that workers within healthcare facilities had been working at maximum capacity for many hours and over many shifts, and in some settings with limited protection. Being a frontline healthcare worker was found to be one of the risk factors for acquiring COVID-19, as shown in many serological studies, such as that by Galanis et al.
- 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).
- Oman’s robust surveillance system was very efficient in guiding the outbreak investigation processes in the country, the study illustrates the future importance of molecular epidemiology in leading the national response to outbreaks and pandemics.
