WHO informed Egypt health authorities of individuals of different nationalities who proved positive for COVID-19 after returning from Egypt. Patients were among touristic group who visited Cairo and spent 1-week onboard Nile cruise ship. Investigation performed to confirm outbreak, detect source, and implement containment measures. Active case finding and contact tracing performed among contacts of the index cases and their contacts. Contacts defined as anyone within 6 feet from confirmed or suspected COVID-19 case for ≥15 min. Overall, 331 contacts, including 201 ship boarders and 130 hotel guests, were listed and interviewed using semistructured questionnaire and tested for COVID-19 by PCR. Among them, 136 (41.1%) were close contacts of index cases and 195 (58.9%) contacted secondary cases. Their mean age was 34.6±11.5 years, 251 (75.8%) were males and 126 (38.1%) non-Egyptians. Of them, 67 (20.2%) tested positive for COVID-19, including 57 (28.4%) ship boarders and 10 (7.7%) hotel guests. Per cent positive was significantly higher in: contacts of index cases, Egyptians, ship boarders and in males than corresponding categories (35.3% vs 9.7%, 22.9% vs 15.9%, 27.4% vs 7.7%, 24.7% vs 6.3%), respectively. Of all positive cases, 40 (59.7%) were asymptomatic where ship boarders, non-Egyptians, >50 years old and females were more likely to be asymptomatic than corresponding categories (85.0 vs 48.9%, 72.7 vs 54.5%, 100.0 vs 56.5%), respectively. COVID-19 patients among group of tourists triggered an outbreak onboard Nile ship and hotel in Egypt. Outbreak quickly contained through lab testing, case isolation, strict infection control measures and contact tracing which proved effective in reducing COVID-19 transmission early in pandemic.
世界卫生组织通知埃及卫生当局，有不同国籍的个人在从埃及返回后被检测出 COVID-19 呈阳性。这些患者是一个旅游团的成员，他们参观了开罗，并在尼罗河游轮上度过了一周。进行了调查以确认疫情爆发、发现源头并实施遏制措施。对指数病例及其接触者的接触者进行了主动病例发现和接触者追踪。接触者定义为与确诊或疑似 COVID-19 病例的距离在 6 英尺以内且接触时间≥15 分钟的任何人。总共列出并采访了 331 名接触者，其中包括 201 名船上乘客和 130 名酒店客人，使用半结构式问卷，并通过 PCR 对 COVID-19 进行了检测。其中，136 名（41.1%）为指数病例的密切接触者，195 名（58.9%）为接触者。他们的平均年龄为 34.6±11.5 岁，251 名（75.8%）为男性，126 名（38.1%）为非埃及人。其中，67 人（20.2%）COVID-19 检测呈阳性，包括 57 名（28.4%）船上乘客和 10 名（7.7%）酒店客人。在以下情况下，阳性率显著更高：指数病例的接触者、埃及人、船上乘客和男性，而相应类别为：35.3%对 9.7%，22.9%对 15.9%，27.4%对 7.7%，24.7%对 6.3%。所有阳性病例中，40 例（59.7%）为无症状病例，其中船上乘客、非埃及人、>50 岁和女性的无症状病例比例高于相应类别：85.0%对 48.9%，72.7%对 54.5%，100.0%对 56.5%）。游轮和埃及酒店的旅游团中的 COVID-19 患者引发了埃及的疫情爆发。通过实验室检测、病例隔离、严格的感染控制措施和接触者追踪，疫情很快得到控制，这些措施在大流行早期被证明有效减少了 COVID-19 的传播。
