Successful containment of COVID-19: the WHO-Report on the COVID-19 outbreak in China

Abstract

SARS-CoV-2 is a new Coronavirus, with first infections detected in humans late in 2019. The emergence of SARS-CoV-2 has led to a large outbreak in China and is currently causing outbreaks in many countries. The disease spectrum ranges from uncomplicated upper respiratory tract infections to severe viral pneumonia with multiorgan failure and death. It can be transmitted by droplets from asymptomatic or oligosymptomatic patients and possibly through aerosols in health care environments. The route of transmission and the spectrum of disease (COVID-19) has motivated many researchers to use models of influenza outbreaks or pandemics to forecast outbreaks of SARS-CoV-2 by analogy. The epicenter of China’s outbreak has been Wuhan and the Hubei province. The Chinese government has restricted travel from and to Hubei province and has implemented a number of measures to contain the outbreak. Meanwhile, the number of new cases per day in China is falling. A WHO mission has visited China and Wuhan to report on the outbreak. They corroborated the outbreak dynamic and case count reported by the Chinese government.
