A novel coronavirus was identified as the cause of a cluster of pneumonia cases in Wuhan, China in December 2019. This cluster quickly spread across the globe and led the World Health Organization (WHO) to declare severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) a pandemic on March 11, 2020. It's sudden emergence, ceaseless human-to-human transmission, and rapid spread has led to continuous pandemicity. As of June 9, 2020, there were 7 039 918 confirmed cases and 404 396 deaths globally. The rate of spread of COVID-19 is affected through respiratory droplets, most commonly when infected individuals cough or talk. The virus is released through respiratory secretions that infect individuals once contact with mucous membranes is made directly or indirectly. Our research was conducted via an electronic literature review on PubMed, Google Scholar, and MedLine Plus. Data were then collected from peer-reviewed articles that included applicable keywords and published between January 1, 2020, and June 9, 2020. This article highlights the rapid spread of SARS-CoV-2 worldwide and indicates a higher number of mortalities in the elderly and those with comorbidities. As the number of cases increases, an immediate need to "flatten the curve" is essential to avoid catastrophic overwhelming of hospital systems across the affected countries. To do so, there is an emphasis on detection, testing, isolating the infected, and organizing the healthcare response to the virus. The rapid spread of infection has impacted over 200 countries and territories to date. This report takes a closer look at the cases, fatalities, and recoveries in different regions of the world with details regarding the geographic scale of SARS-CoV-2 spread, risks, and the subsequent impact on the countries affected. Also, this report discusses some effective measures that were carried out by some countries that helped them to mitigate the pandemic and flatten the curve of COVID-19 spread as early as possible.
2019年12月,一种新型冠状病毒被确认为中国武汉一群肺炎病例的病因。这一群体迅速蔓延至全球,导致世界卫生组织(WHO)于2020年3月11日宣布严重急性呼吸综合征冠状病毒2(SARS-CoV-2)为大流行病。它的突然出现、持续的人际传播以及快速传播导致了疫情的持续蔓延。截至2020年6月9日,全球共有7039918例确诊病例和404396例死亡病例。COVID-19的传播速度受呼吸道飞沫影响,最常见于受感染个体咳嗽或交谈时。病毒通过呼吸道分泌物释放,一旦直接或间接接触到黏膜就会感染个体。我们的研究是通过对PubMed、谷歌学术和MedLine Plus进行电子文献综述来进行的。然后从2020年1月1日至2020年6月9日期间发表的、包含适用关键词的同行评审文章中收集数据。本文强调了SARS-CoV-2在全球的快速传播,并指出老年人和患有合并症的人死亡率更高。随着病例数量的增加,迫切需要“ flatten the curve”(平缓曲线,即减缓疫情传播速度)以避免受灾国家的医院系统不堪重负。为此,重点在于检测、测试、隔离感染者以及组织针对该病毒的医疗应对措施。迄今为止,感染的快速传播已影响到200多个国家和地区。本报告更深入地研究了世界不同地区的病例、死亡和康复情况,详细介绍了SARS-CoV-2传播的地理范围、风险以及对受影响国家的后续影响。此外,本报告还讨论了一些国家采取的有助于减轻疫情并尽早平缓COVID-19传播曲线的有效措施。
