The present study provides an overview of the coronavirus disease 2019 (COVID-19) outbreak which has rapidly extended globally within a short period. COVID-19 is a highly infectious respiratory disease caused by a new coronavirus known as SARS-CoV-2 (severe acute respiratory syndrome-coronavirus-2). SARS-CoV-2 is different from usual coronaviruses responsible for mild sickness such as common cold among human beings. It is crucial to understand the impact and outcome of this pandemic. We therefore overview the changes in the curves of COVID-19 confirmed cases and fatality rate in China and outside of China from 31 of December 2019 to 25 of March 2020. We also aimed to assess the temporal developments and death rate of COVID-19 in China and worldwide. More than 414,179 confirmed cases of COVID-19 have been reported in 197 countries, including 81,848 cases in China and 332,331 outside of China. Furthermore, 18,440 infected patients died from COVID-19 infection; 3,287 cases were from China and 15,153 fatalities were reported worldwide. Among the worldwide infected cases, 113,802 patients have been recovered and discharged from different hospitals. Effective prevention and control measures should be taken to control the disease. The presented Chinese model (protocol) of disease prevention and control could be utilized in order to curb the pandemic situation.
本研究概述了 2019 年冠状病毒病(COVID-19)疫情,该疫情在短时间内迅速在全球范围内蔓延。COVID-19 是一种由新型冠状病毒 SARS-CoV-2(严重急性呼吸系统综合症冠状病毒-2)引起的高度传染性呼吸道疾病。SARS-CoV-2 与通常导致人类轻度疾病(如普通感冒)的冠状病毒不同。了解这种大流行的影响和结果至关重要。因此,我们综述了 2019 年 12 月 31 日至 2020 年 3 月 25 日期间中国和中国境外 COVID-19 确诊病例和病死率曲线的变化。我们还旨在评估 COVID-19 在全球的时间发展和死亡率。在 197 个国家/地区已报告超过 414,179 例 COVID-19 确诊病例,其中包括中国 81,848 例,中国境外 332,331 例。此外,有 18,440 名感染者死于 COVID-19 感染;中国有 3,287 例,全球有 15,153 例死亡。在全球感染病例中,有 113,802 名患者已从不同医院康复出院。应采取有效的预防和控制措施来控制疾病。可以利用中国提出的疾病预防和控制模式来控制大流行局面。
