The recent Coronavirus disease 2019 (COVID-19) pandemic outbreak has forced many countries to adopt specific austere “lockdown politics,” which had reduced the spreading of the infection in China, South Korea, Japan, Hong Kong, and Singapore, and have more recently started to slow down the infection rates in many European countries, severely hit by the epidemic (e.g., Italy and Spain). Considering the lack of vaccination, it is reasonable to think that, especially for children and older people, most of these lockdown measures will be prolonged for the next months, even if it is still too soon to precisely predict for how long.
In this context, many nations are experiencing an unprecedented distortion of social habits and medical assistance for people and patients of all ages, including children. Interruption of school, sport, and other social activities is forcing children to stay home for most of their time, in close contact with (often idle) parents. Moreover, lockdown has a direct effect in the reduction of activities in non-COVID emergency rooms and hospital wards caused by the shift of personnel towards COVID-units and by a diffuse “germaphobia” (fear of germs and infections, and as a consequence of hospitals). In most of the hospitals many “COVID-units” (as well as COVID-pediatric units) have been quickly created, and, at the same time, in the other units, activities have been focused more on patients affected by severe and acute conditions, reducing the care and assistance for patients affected by chronic or rare diseases.
This “motionless revolution” is taking to Health Care personnel and patients many disadvantages, with inestimable consequences, but also some opportunities that will be unique and reproducible with difficulty when the emergency will cease.
Even if COVID-19 does not seem to affect children severely, many pediatrics wards have been focused more on the emergency of COVID-19-related issues. For this reason, attention on many other acute and chronic diseases, especially those rarer, may be lacking. This scarcity of interest may cause, particularly in childhood, severe problems or even death. Politicians and physicians may be distracted by COVID-19-related issues, but also parents or even the same young patients, as these last’s attention may be focused only on news and information related to COVID-19, misunderstanding some symptoms or paying less attention to their (chronic) diseases.
Neuropsychiatric and psychological issues related to lockdown are another significant issue. The house confinement for children can be easily practiced in the first weeks, as they can be particularly fascinated by unexpected and new habits, but a prolonged lack of routine school programs and housework, as well as sport and leisure activities, could increase the occurrence of psychological consequences and distress. More than other primates, Homo sapiens is a highly social species, and children develop in the first years of their life specific social abilities exclusively out of their houses. It is reasonable to think that we will face an underestimation of children needing school assistance for (missed) learning difficulties if schools will be closed until September 2020. Adolescents and older children are at high risk of cell phone, computer, and other internet devices overuse, which has been linked to obesity and its related issues. Moreover, spending more time in non-filtered social networks, they could be also invested by fake news and anti-scientific theories related to COVID-19, increasing their fears and phobias.
Lastly, the economic breakdown, expected in most of the countries, will probably involve the national health systems, especially pediatric departments and units not involved in emergency and infectious diseases, limiting the experience, progresses, and even the simple management of many genetic, congenital, and chronic disorders, with severe social effects, especially for children.
From the first reports from Eastern countries, we know that, in children, COVID-19 manifests with a milder course and a more favorable outcome, with only a minority of patients presenting with complications. Mortality under 18 years of age is exceptionally low, differently from other well-known “historical pandemics” (e.g., influenza, measles, polio, smallpox). Such favorable outcome in children is matter of debate, and many “causes” have been proposed, including the role of active immunization schedules for other viruses performed in the first years of life, the simultaneous presence of other viruses in the mucosa of lungs and airways, common in young children, which could limit the growth of severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) by direct virus-to-virus interactions and competition; important factors seem to be the under-expression of angiotensin-converting enzyme 2 receptor necessary for SARS-Cov2 binding and infection, and a milder inflammatory cascade, as children usually do not manifest, in respiratory infections, the final hyperinflammatory phase that leads to severe acute respiratory distress syndrome, impaired cardiac function, and death. Studying pediatric patients will give the chance to investigate all these factors directly: key results could come evaluating the immune response of asymptomatic children compared to symptomatic, or comparing children and adults within the same families or ethnic groups.
Another opportunity will come—paradoxically—from the lockdown politics. In no other period of the recent history, children have been forcedly restricted to their houses, with closure of schools, and strong limitations of social and sport activities. A significant decrease of many (other than-COVID-19) infectious diseases has been observed in March in Italian children. In this setting, a reconsideration of many (common) problems of pediatric practice, from chronic cough to unexplained fever will be possible, withdrawing the bias of common infections (typically spreading in schools): many pediatricians could have the possibility to re-diagnose chronic cough as caused by gastro-esophageal reflux, in-house allergens, respiratory tract malformations, and other non-infective causes; others could have a higher chance of investigating recurrent febrile episodes as caused by genetic, autoimmune, or oncologic disorders.
