Abstract

The virus named SARS-CoV-2 causes the clinical syndrome named Coronavirus Disease 2019 (COVID-19) and first emerged in Wuhan, China, in December 2019. On January 11, 2020, the first COVID-19-related death was reported in China. The COVID-19 pandemic rapidly emerged around the globe and has presented as at least three waves. Resources and responses have differed across countries, regions, and sovereignties with major differences in case numbers and fatality rates. As of April 2022, there have been more than 490,000,000 COVID-19 cases and 6,000,000 related deaths globally according to the Johns Hopkins Coronavirus Resource Center Dashboard. This resource is continuously updated with COVID-19 data from the World Health Organization, European Centre for Disease Prevention and Control, multiple state-level governments in the USA, among others. Using data from this dashboard and published studies, the present chapter examines the global epidemiology of COVID-19.

Summary

The COVID-19 pandemic began in late 2019/early 2020. As of April 2022, there have been more than 490,000,000 cases and 6,000,000 deaths around the globe. COVID-19 impacted nations across the globe and presented in at least three different waves, requiring coordination of care, testing, social distancing, and other measures. Resources and responses have varied by country/region/sovereignty, [47,48,49] with differences in case numbers and fatality rates. The differences in statistics across countries may in part relate to differences in reporting of COVID-19 cases, with major potential for underreporting related to asymptomatic cases and the lack of testing. Throughout the COVID-19 pandemic, Johns Hopkins has remained committed to providing up-to-date data and trends regarding COVID. Since the release of the COVID-19 vaccination, Johns Hopkins COVID Dashboard provides statistics as to how many people are vaccinated, as well [47,48,49].
