摘要
Acute respiratory infections (ARI), especially lower respiratory infections (LRI), are a leading cause of childhood morbidity and mortality globally. Non-pharmaceutical interventions (NPI) employed during the COVID-19 pandemic have impacted on the epidemiology and burden of paediatric ARI, although accurately describing the full nature of the impact is challenging. For most ARI pathogens, a reduction was observed in the early phase of the pandemic, correlating with the most stringent NPI. In later phases of the pandemic resurgence of disease was observed as NPI eased. This pattern was most striking for seasonal viruses, such as influenza and respiratory syncytial virus. The impact on ARI-associated bacterial disease varied; marked reductions in invasive Streptococcus pneumoniae and Streptococcus pyogenes were observed, followed by a resurgence that correlated with increases in respiratory viral infections. For Corynebacterium diphtheriae,Bordetella pertussis, andMycoplasma pneumoniae, a sustained reduction of disease was observed well into 2022 in most regions. Proposedmechanisms for the varied epidemiological disruption amongst ARI pathogens includedifferential effects of NPI on specific pathogens, population-level immunological effects, and ecological and genetic pathogen adaptations. Additionally, important indirect effects of pandemic restrictions on paediatric respiratory infections have been identified. These occurred as a result of disruptions to routine health services, reductions in vaccination coverage, and disruptions to respiratory infection research and surveillance activities. Impacts have been disproportionately borne by those in low resource settings. We discuss opportunities to leverage pandemic learnings to support improved understanding of the epidemiology of paediatric respiratory infections to inform future prevention and health system strengthening.
