COVID-19 (coronavirus disease 2019) is an infectious respiratory illness caused by the novel coronavirus SARS-CoV-2, first identified in late 2019 and subsequently declared a pandemic by the World Health Organization. The virus spreads chiefly through respiratory droplets and aerosols produced when an infected person breathes, talks, coughs, or sneezes, and it can cause illness ranging from mild or asymptomatic infection to severe pneumonia, multi-organ involvement, and death. Older adults and people with underlying conditions are at higher risk of severe outcomes, and vaccines and public health measures have been central to controlling its spread. As a recent global emergency, COVID-19 has generated research across epidemiology, prevention, and clinical care. Studies in this journal include mathematical modeling and epidemic prediction to inform control measures, analyses of knowledge and risk exposure in African settings, the potential role of vitamin D in risk and severity among older adults, knowledge and preventive practices among pregnant women, mortality factors in patients with cancer and diabetes, and vaccine willingness and hesitancy in various populations. Additional work considers the pandemic's effects on education and training and its intersection with chronic conditions such as osteoarthritis. Key aspects of the field include transmission and prevention, epidemiological modeling, risk factors for severe disease, vaccination, and the wider social and health-system impacts of the pandemic.
