Seasonal epidemics of influenza and the respiratory syncytial virus are
the cause of substantial morbidity and mortality among children. During
the global COVID-19 pandemic, the epidemiology of these viruses seems to
have changed dramatically. In Australia and New Zealand, a significant
decrease in both influenza and bronchiolities have been noticed during
usual peak seasons. Data from early months of winter seasons in Europe
are showing similar trends. This current scenario imposes a
reconsideration of the paradigm that toddlers and young schoolchildren
are the main drivers of seasonal RSV outbreaks and respiratory epidemics
in general. In this paper, we summarize current literature, address
current knowledge or role of adults in the respiratory syncitial virus
epidemiology, describe the lessons learned from pertussis epidemics and
call the international community to better understand the community
transmission dynamics of respiratory infections in all age-groups. This
can allow the establishment of better and more affordable preventive
measures in the whole population level, which can ultimately save
millions of child lives.
