In December 2019, a new infectious respiratory disease called COVID-19 was identified in Wuhan, Hubei province, in China and quickly reached pandemic status in March 2020, in uncertain and frightening situation. The objective of this study was to analyze the epidemiological curves from the fight against COVID-19 in China and Italy, establishing parameters that can assist with the decisions of health-planning managers. This study was conducted using the principles of the grounded theory methodology and a practical method of comparison between the real and ideal curves, based on the contamination and death data by SARS-CoV-2 in China and Italy. For this purpose, we built graphs, including parameters, such as, among others, amplitude, height, saturation point, acceleration, lethality, event, risk, and efficiency. The results of our study showed that China exhibited amplitude and height of the active contamination and death curve 2 times smaller than those of Italy which exhibited several saturations. It was investigated that Italy presented a qualitative risk of 5-6, whereas for China it was 4. According to the parameters, China and Italy presented health management that was able to reduce the impact caused by the virus. The implementation of adequate health management with these practical tools can guide perception of the crisis critical levels, avoiding major disasters. We intend to continue to validate the method in the analysis of data from Brazil and the USA.
2019 年 12 月,在中国湖北省武汉市发现了一种名为 COVID-19 的新型传染性呼吸道疾病,该疾病于 2020 年 3 月迅速进入大流行状态,情况不确定且令人恐惧。本研究的目的是分析中国和意大利抗击 COVID-19 的流行病学曲线,确定可协助卫生规划管理者做出决策的参数。本研究采用扎根理论方法的原则和基于 SARS-CoV-2 在中、意两国的污染和死亡数据的真实与理想曲线之间的比较的实用方法进行。为此,我们构建了图表,包括幅度、高度、饱和点、加速度、致死率、事件、风险和效率等参数。我们的研究结果表明,中国的活跃感染和死亡曲线的幅度和高度比意大利小两倍,意大利出现了多个饱和点。调查显示,意大利的定性风险为 5-6,而中国为 4。根据这些参数,中国和意大利实施的卫生管理能够减轻病毒造成的影响。使用这些实用工具实施适当的卫生管理,可以指导对危机关键水平的认识,避免发生重大灾害。我们打算继续在分析巴西和美国的数据时验证该方法。
