Abstract

Background: Invasive group A streptococcal disease (iGAS) is caused by Streptococcus pyogenes group A bacteria. In 2022, multiple disease alerts for iGAS in the Island Health region, in the context of increased infections in the paediatric population in Europe and the United States, prompted further investigation into local trends. This surveillance study summarizes epidemiological trends of iGAS in the region covered by Island Health, a regional health authority in British Columbia, in 2022.

Methods: In British Columbia, iGAS is a reportable disease; all confirmed cases are reported to the regional authority and the provincial health authority (BC Centre for Disease Control). Island Health's iGAS surveillance system is passive and collects information on cases that are identified through laboratory testing. Surveillance data were summarized for 2022 and compared with historical data from 2017-2021.

Results: In 2022, the incidence rate was 11.4 cases per 100,000 population (n=101), the highest observed rate in the last six years. The median age of cases was 53 years, with a range of 0-96 years, and 64% of cases were male. The highest risk of infection was reported in men 40-59 years of age, with an incidence rate of 21.3 cases per 100,000 population. The most common emm types were emm92 (n=14), emm49 (n=13), and emm83 (n=12). Overall, 85% (n=86) of cases were hospitalized, 21% (n=21) were admitted to the intensive care unit, and 6% (n=6) died.

Conclusion: This study highlights that the incidence of iGAS in the Island Health region continued to increase throughout the coronavirus disease 2019 (COVID-19) pandemic, reaching its highest annual rate in 2022. In contrast to reports from Europe and the United States, there was no notable increase in infections in the paediatric population. Given the sustained increase in iGAS activity, continued monitoring and description of the epidemiology of these cases on a regular basis is imperative.

2022 年，不列颠哥伦比亚省岛屿卫生部对侵袭性 A 群链球菌 (iGAS) 进行监测。

背景：侵袭性 A 组链球菌疾病（iGAS）由化脓性链球菌 A 组细菌引起。2022 年，在欧洲和美国儿科感染率上升的背景下，Island Health 地区多次发出 iGAS 疾病警报，促使人们进一步调查当地的趋势。本监测研究总结了 2022 年不列颠哥伦比亚省地区卫生局 Island Health 所辖地区 iGAS 的流行趋势：在不列颠哥伦比亚省，iGAS 是一种需要报告的疾病；所有确诊病例都要向地区卫生局和省卫生局（不列颠哥伦比亚省疾病控制中心）报告。岛屿卫生局的 iGAS 监控系统是被动的，收集通过实验室检测确定的病例信息。对2022年的监测数据进行了汇总，并与2017-2021年的历史数据进行了比较：2022 年的发病率为每 10 万人 11.4 例（n=101），是过去六年中观察到的最高发病率。病例年龄中位数为 53 岁，范围在 0-96 岁之间，64% 的病例为男性。据报告，40-59 岁的男性感染风险最高，发病率为每 10 万人 21.3 例。最常见的emm类型为emm92（14人）、emm49（13人）和emm83（12人）。总体而言，85%（n=86）的病例住院治疗，21%（n=21）入住重症监护室，6%（n=6）死亡：本研究强调，在冠状病毒病2019（COVID-19）大流行期间，海岛卫生地区的iGAS发病率持续上升，在2022年达到最高年发病率。与欧洲和美国的报告不同的是，儿科人群的感染率没有明显上升。鉴于 iGAS 活动的持续增加，继续定期监测和描述这些病例的流行病学情况势在必行。

期刊介绍： The Journal of Material Culture is an interdisciplinary journal designed to cater for the increasing interest in material culture studies. It is concerned with the relationship between artefacts and social relations irrespective of time and place and aims to systematically explore the linkage between the construction of social identities and the production and use of culture. The Journal of Material Culture transcends traditional disciplinary and cultural boundaries drawing on a wide range of disciplines including anthropology, archaeology, design studies, history, human geography, museology and ethnography.
