In a multifacility prospective cohort study, we identified 116 acute care, 26 long-term care, and 67 rehabilitation patients who received direct care from a universally masked healthcare worker while communicable with COVID-19. Among 133(64%) patients with at least 14-day follow-up, 3 (2.3%, 95% CI, 0.77-6.4) became positive for SARS-CoV-2. Universal masking, embedded with other infection control practices, is associated with low risk of transmission of SARS-CoV-2 from healthcare workers to patients and residents.
在一项多机构前瞻性队列研究中，我们发现 116 名急性护理、26 名长期护理和 67 名康复患者在与 COVID-19 患者有传染性期间接受了普遍戴口罩的医护人员的直接护理。在 133 名（64%）至少有 14 天随访的患者中，有 3 名（2.3%，95%CI，0.77-6.4）SARS-CoV-2 检测呈阳性。普遍戴口罩与其他感染控制措施相结合，与医护人员向患者和居民传播 SARS-CoV-2 的风险较低相关。
