摘要:

截至2020年4月30日,新型冠状病毒爆发的累计确诊感染人数为以下国家:比利时,巴西,英国(英国)和美利坚合众国(美国)。在新感染者发病率较低的最初阶段之后,观察到确诊病例数量呈幂律增长。对于每个国家,获得不同的增长指数。对于比利时、英国和美国这些感染人数众多的国家,在幂律增长之后,当接近饱和时会获得明显的行为。巴西仍处于权力法律制度之下。这些数据和预测的更新证实了最近关于病毒的幂律增长及其在世界各地一些国家之间的强距离相关性的结果。此外,我们表明,及时采取行动是卫生组织在抗击COVID-19(由最近发现的冠状病毒引起的传染病)的斗争中最相关的非药物武器之一。我们研究了在不同的三天,即4月16日(早期)、4月30日(当前)和5月14日(晚期)应用时,改变社交距离和每日检测次数以识别感染的无症状个体如何干扰COVID-19确诊病例的数量。结果表明,遏制行动是必要的,以平坦的曲线,并应尽快实施。

英文摘要:

The cumulative number of confirmed infected individuals by the new coronavirus outbreak until April 30th, 2020, is presented for the countries: Belgium, Brazil, United Kingdom (UK), and United States of America (USA). After an initial period with a low incidence of newly infected people, a power-law growth of the number of confirmed cases is observed. For each country, a distinct growth exponent is obtained. For Belgium, UK, and USA, countries with a large number of infected people, after the power-law growth a distinct behavior is obtained when approaching saturation. Brazil is still in the power-law regime. Such updates of the data and projections corroborate recent results regarding the power-law growth of the virus and their strong Distance Correlation between some countries around the world. Furthermore, we show that act in time is one of the most relevant non-pharmacological weapons that the health organizations have in the battle against the COVID-19, infectious disease caused by the most recently discovered coronavirus. We study how changing the social distance and the number of daily tests to identify infected asymptomatic individuals can interfere in the number of confirmed cases of COVID-19 when applied in three distinct days, namely April 16th (early), April 30th (current), and May 14th (late). Results show that containment actions are necessary to flatten the curves and should be applied as soon as possible.
