• Whether SARS-CoV-2 infection confers immunity to reinfection is uncertain. • The ‘second wave’ of transmission offered an opportunity to examine this. • We observed no symptomatic reinfections in a cohort of healthcare workers. • This apparent immunity to re-infection was maintained for at least 6 months. • Further studies are required to define immunological mechanism(s) and durability.
• SARS-CoV-2 感染是否能提供再次感染的免疫力还不确定。• 传播的“第二波”提供了一个检验的机会。• 在一组医护人员中，我们没有观察到有症状的再次感染。• 这种对再次感染的明显免疫力至少能维持 6 个月。• 需要进一步的研究来明确免疫机制和持久性。
