Could COVID-19′s Aftermath on Children’s Health Be Felt into the 22nd Century?

The COVID-19 pandemic has massively affected people’s health, societies, and the global economy. Our lives are no longer as they were before COVID-19, and, most likely, will never be the same again. We hypothesize that the effect of the COVID-19 pandemic on population health and the economy will last for a very long time and will still be felt in the 22nd century. Our hypothesis is based on evidence from the 1918–1919 influenza pandemic, the Dutch famine during the Second World War, and the 2007–2008 economic crisis, as well as from the rationally predicted impact of COVID-19 on human development. We expect that the COVID-19 pandemic, including the mitigation measures taken against it, will affect children’s development in multiple ways, including obesity, both while in utero and during critical and sensitive windows of development, including the early childhood years and those of puberty and adolescence. The psychosocial and biological impact of this effect will be considerable and unequally distributed. The implications will last at least a lifetime, and, through inter-generational transmission, will likely take us to future generations, into the 22nd century. We argue for the urgent need of designing and initiating comprehensive longitudinal cohort studies to closely monitor the long-term effects of COVID-19 on children conceived, born, and raised during the pandemic. Such an approach requires a close and effective collaboration between scientists, healthcare providers, policymakers, and the younger generations, and it will hopefully uncover evidence necessary to understand and mitigate the impact of the pandemic on people’s lives in the 21st and 22nd centuries.
