摘要

背景:新冠肺炎大流行是一个令人困惑的现象,关于其各个方面的完整知识尚未获得。目的:本研究旨在比较伊拉克和其他几个国家2019冠状病毒病大流行的流行病学特征。方法:本文使用了伊拉克和其他8个国家的每日COVID-19大流行病例数据,其中3个来自东地中海地区(巴林、伊朗和黎巴嫩),4个来自欧洲(希腊、瑞士、奥地利和挪威)以及巴西。选择这些国家的依据是大流行发病日期的相似性。从CoronaWorld meters、www.sehhty和伊拉克卫生部等几个网站获得了有关新病例每日报告的相关数据。结果:在本文研究的9个国家中,COVID-19病例的时间趋势(流行曲线)和3个流行病学结局指标(发病率、病死率和病因特异性死亡率)在大流行的前5个月内存在显著差异。四个欧洲国家——希腊、瑞士、奥地利和挪威——实现了一条水平曲线,尽管它们在三种结果测量上存在差异,但仍然保持着这种水平曲线。其他国家无法在其流行病曲线上实现任何可持续的平衡,而且结果测量也各不相同。在这些国家中,巴林的发病率最高(15531.3/百万人),但病死率最低(0.4%)。巴西的死因特异性死亡率最高(274.7/百万),希腊的病死率最高(12.2%)。其他国家的数值也在这个范围内。结论:COVID-19疫情在过去5个月内的结果很难预测。不同国家表现出不同的感染相关行为和流行病学参数。对这些变化背后可能存在的多种因素进行研究,将有助于促进成功地摆脱大流行病。关键词:COVID-19,流行病学,流行曲线,发病率

Comparison of the Epidemiological Features of COVID-19 in Iraq and Selected Countries
Background: The COVID-19 pandemic is a puzzling phenomenon and complete knowledge regarding its various aspects is yet to be available. Objective: This research aims to present a comparative profile of the epidemiological features of the COVID-19 pandemic in Iraq and several other countries. Methods: This paper used data on the daily cases of COVID-19 pandemic in Iraq and eight other countries— three from the Eastern Mediterranean region (Bahrain, Iran and Lebanon), four from Europe (Greece, Switzerland, Austria and Norway), along with Brazil. These countries were chosen based on the similarity in the date of onset of the pandemic. Relevant data were obtained from several websites, including Corona World meters, www.sehhty and the Iraqi Ministry of Health for daily reports on new cases. Results: Substantial variations were found in the time trend of COVID-19 cases (epidemic curves) and three epidemiological outcome measurements (incidence rate, case fatality ratio and cause-specific mortality rate) during the first five months of the pandemic in the nine countries studied in this paper. The four European countries—Greece, Switzerland, Austria and Norway—achieved a leveled curve and still maintain such leveling despite their differences in the three outcome measurements. The rest of the countries could not achieve any sustainable leveling in their epidemic curves and also had varying outcome measurements. Among these countries, Bahrain showed the highest incidence rate (15531.3/million) but the lowest case fatality ratio (0.4%). Brazil had the highest cause-specific mortality rate (274.7/million), and Greece had the highest case fatality ratio (12.2%). The other countries had values that were within these ranges. Conclusions: The outcome of COVID-19 within the last five months of experience with the pandemic is very difficult to predict. Different countries have exhibited diverse infection-related behaviors and epidemiological parameters. A study of the multiple factors that might be behind such variations would be helpful in facilitating a successful exit from the pandemic. Keywords: COVID-19, epidemiology, epidemic curve, incidence rate
