Five months after the first confirmed case of COVID-19 in Brazil, the country has the second highest number of cases in the world. Without any scientifically proven drug or vaccine available combined with COVID-19's high transmissivity, slowing down the spread of the infection is a challenge. In an attempt to save the economy, the Brazilian government is slowly beginning to allow non-essential services to reopen for in-person customers.
In this study, we analyze, based on data analysis and statistics, how other countries evolve and under which conditions they decided to resume normal activity. In addition, due to the heterogeneity of Brazil, we explore Brazilian data of COVID-19 from the State Health Secretaries to evaluate the situation of the pandemic within the states.
Results show that while other countries have flattened their curves and present low numbers of active cases, Brazil continues to see an increase in COVID-19 patients. Furthermore, a number of important states are easing restrictions despite a high percentage of confirmed cases.
All analyses show that Brazil is not ready for reopening, and the premature easing of restrictions may increase the number of COVID-19-related deaths and cause the collapse of the public health system.
巴西首例新冠肺炎确诊病例出现五个月后,该国成为全球确诊病例数第二高的国家。由于没有任何经过科学验证的药物或疫苗,再加上新冠病毒的高传染性,减缓疫情传播是一项挑战。为了挽救经济,巴西政府正逐步允许非必要服务重新向顾客开放。
本研究通过数据分析和统计学分析,探讨了其他国家的疫情演变情况,以及它们在何种条件下决定恢复正常活动。此外,由于巴西的情况存在异质性,我们还从州卫生部长那里探索了巴西新冠肺炎数据,以评估各州的疫情状况。
结果表明,尽管其他国家的曲线已经趋于平缓,活跃病例数较低,但巴西的新冠肺炎患者数量仍在持续增加。此外,尽管确诊病例百分比较高,但一些重要的州仍在放宽限制。
所有分析都表明,巴西尚未准备好重新开放,过早放宽限制可能会导致新冠肺炎死亡人数增加,并使公共卫生系统崩溃。
