INTRODUCTION
As of 30 April 2020, 203.715 SARS-CoV-2 infections had been reported in Spain, 54.486 in Madrid, 21.4% were health care workers. Our objective is to determine seroprevalence of COVID-19 among workers in a monographic pediatric hospital.
METHODS
Between April13 and 30, 1.523 health workers were recruited to be tested for SARS-CoV-2 serology screening (All Test®) and they answered a questionnaire with demographic, epidemiological and clinical information and previous exposure to COVID-19.
FINDINGS
One thousand two hundred ninety two (84.8%) were tested. Positive serology (IgM and/or IgG) to SARS-CoV-2 was found in 17.2% (222/1.292), in 15.5% (201/1.292) if only IgG was considered. Median age was 44±13 years, 73% were female. The 33.8% (75/222) were asymptomatic. Eighty one had a previous positive rRT-PCR. The 14% (32/222) referred a family contact.
CONCLUSION
Serology prevalence for SARS-CoV-2 in workers of a pediatric hospital was higher than in general population. Many of them had an unnoticed infection.
简介
截至 2020 年 4 月 30 日，西班牙报告了 203715 例 SARS-CoV-2 感染病例，马德里报告了 54486 例，其中 21.4%为医护人员。我们的目的是确定一家专题儿科医院工作人员中 COVID-19 的血清流行率。
方法
4 月 13 日至 30 日期间，招募了 1523 名卫生工作者进行 SARS-CoV-2 血清学筛查（All Test®），并回答了一份包含人口统计学、流行病学和临床信息以及以前接触过 COVID-19 的问卷。
结果
共检测了 1292 人（84.8%）。17.2%（222/1292）的人 SARS-CoV-2 血清学（IgM 和/或 IgG）呈阳性，仅 IgG 考虑时为 15.5%（201/1292）。中位年龄为 44±13 岁，73%为女性。33.8%（75/222）无症状。81 人之前的 rRT-PCR 检测结果为阳性。14%（32/222）的人报告有家庭接触史。
结论
儿科医院工作人员中 SARS-CoV-2 的血清流行率高于一般人群。他们中的许多人感染了未被发现的病毒。
