To describe the epidemiological characteristics of the first 69,382 patients with COVID-19 infection in Oman.
A retrospective case series study of patients diagnosed with SARS-CoV-2 infection in Oman from 24 February to 23 July 2020. The data were obtained from the National surveillance COVID-19 network.
The overall mean age of patients was 34 (± 14) years, 74% (n = 51,391) were males, 40,859 (59%) were Omani citizens, and 28,523 (41%) were foreign-born individuals. The most common symptoms at presentation were fever 50% (n = 34,600), cough 46% (n = 32,062), sore throat 46% (n = 31,953) and shortness of breath (SOB) 35% (n = 24,567). Overall, 8,960 (12.9%) patients required hospitalization with 1189 (13.3%) individuals requiring admission to the intensive care unit (ICU) and mechanical ventilation (MV). Patients hospitalized with COVID-19 infection were mostly Omani nationals and males between 30 and 39 years old (p < 0.001). The mortality rate was 7.7 per 100,000 population (n = 359) with rates of 9.4 (n = 278) and 4.8 (n = 81) deaths per 100,000 population in Omani nationals and foreign-born individuals, respectively. Females hospitalized with COVID-19 had a mean age of 64 (± 18) years versus a mean age of 55 (± 17) years in males. Mean age of patients with COVID-19-related mortality was 58 (± 18) years with significant differences in mean age between females and males 64 (± 18) versus 55 (± 17) years, respectively.
Young Omani males accounted for the highest incidence of COVID-19 infection and hospitalization, while mortality rates were higher among males and the older age (> 50 years). Identifying the epidemiological characteristics and outcomes of COVID-19-infected patients is essential for developing targeted intervention strategies and preparing for the resurgence of anticipated second and third waves of this pandemic.
描述阿曼首例 69382 例 COVID-19 感染患者的流行病学特征。
对 2020 年 2 月 24 日至 7 月 23 日期间在阿曼被诊断为 SARS-CoV-2 感染的患者进行回顾性病例系列研究。数据来自国家 COVID-19 监测网络。
患者的总体平均年龄为 34（±14）岁，74%（n=51391）为男性，40859（59%）为阿曼公民，28523（41%）为外国出生。就诊时最常见的症状是发热 50%（n=34600）、咳嗽 46%（n=32062）、咽痛 46%（n=31953）和呼吸急促 35%（n=24567）。总体而言，有 8960（12.9%）名患者需要住院治疗，其中 1189（13.3%）人需要入住重症监护病房（ICU）和机械通气（MV）。因 COVID-19 感染住院的患者主要是阿曼国民和 30 至 39 岁的男性（p<0.001）。死亡率为每 10 万人中有 7.7 人（n=359），阿曼国民和外国出生者的死亡率分别为每 10 万人中有 9.4 人（n=278）和 4.8 人（n=81）。COVID-19 住院女性的平均年龄为 64（±18）岁，而男性的平均年龄为 55（±17）岁。COVID-19 相关死亡率患者的平均年龄为 58（±18）岁，女性和男性的平均年龄存在显著差异，分别为 64（±18）岁和 55（±17）岁。
年轻的阿曼男性 COVID-19 感染和住院的发病率最高，而死亡率在男性和年龄较大者（>50 岁）中更高。确定 COVID-19 感染患者的流行病学特征和结局对于制定有针对性的干预策略和为预期的第二波和第三波大流行做好准备至关重要。
