Surges in infections caused by respiratory pathogens have been documented in multiple settings after relaxation of pandemic restrictions. Antibodies to major antigens from respiratory syncytial virus and Group A Streptococcus waned significantly in a longitudinal adult cohort throughout the pandemic. This waning may have contributed to the pathogen-surges that followed.

COVID-19 大流行期间针对主要病毒和细菌呼吸道病原体的抗体下降


在放宽大流行限制后，由呼吸道病原体引起的感染激增已在多种环境中被记录下来。在整个大流行期间，针对呼吸道合胞病毒和 A 组链球菌的主要抗原的抗体在纵向成人队列中显着减弱。这种减弱可能是导致随后病原体激增的原因。
