When fall arrives, Pediatric emergency medicine (PEM) knows before the trees decide to change leaves. The increase in the number of patients is as important as the repetition of the reasons for consultation and of the explanations of the futility of "treatments for viruses". In addition to colds with and without fever that lead to the PEM collapse, there are severe symptoms of bronchiolitis, laryngitis, asthma attacks, and pneumonia that demand specialized care.

At the beginning of 2020, Sars-Cov-2 pandemic changed people's way of life. The health services underwent an organizational transformation to respond with the greatest possible security to the care of patients, trying to reduce the risk of contagion between them and the health personnel. The emergency services converted into the place of the first impact after the suspension of primary care and medical offices had to adapt to the new epidemiological situation.

As confirmed COVID 19 cases piled up and winter progressed, we were able to observe some notable changes. In May and June of this year, the monthly consultations in our service were reduced by 80% compared to the 12,000 consultations in 2018 and 2019. Although the “Stay at home” campaign and the fear of contagion could have influenced this decrease, I estimate that the decrease in disease burden due to the lack of viral transmission due to confinement also played an important role (Figures 1and2).

The magnitude of this global decrease in visits suggests that a combination of biological, psychological, and social factors influences the decisions of families to attend emergency and emergency services1.

At the end of June, we observed a decrease of more than 50% in hospitalization since the PEM, but with a relative increase in the number of consultations. Fewer patients came, but with more urgent care needs. We corroborate this with the 4.5% increase in hospitalized children and a 5% increase in triage priority levels I, II, and III2.

The burden of respiratory disease in May and June, (bronchiolitis, laryngitis, pneumonia, asthma attacks, recurrent obstructive bronchial syndromes, influenza-like illness, and upper respiratory tract infections), presented a 95% decrease compared to the previous two years in our service (Figure 3).

Bronchiolitis, an acute lung disease of the lower airways caused by respiratory viruses, is the most common reason worldwide for hospitalization in young children3. Usually, it demands a significant consumption of resources, overloads the health system and, above all, causes morbidity and death in children with risky conditions. However, it presented a dramatic decrease in the epidemic period analyzed inFigure 4

We know that almost all children are exposed to the respiratory syncytial virus (RSV) and other viral pathogens (eg, rhinovirus) during the first and second years of life. Of these, ~40% of children develop bronchiolitis clinical, and between 3 and 10% will be hospitalized4,5.

In 2009 alone, there were 130,000 hospitalizations for bronchiolitis (18% of childhood hospitalizations), at a direct cost of $ 550 million, in the United States6,7. We have not analyzed the costs in our hospital, but 567 hospitalizations of children with moderate to severe bronchiolitis in just 2 months of 2019, undoubtedly represent a challenge. If we estimate a requirement of ~5% mechanical ventilator attendance8and ~10% need for noninvasive ventilation or high-flow oxygen by nasal cannula, the magnitude of the impact can be easily deduced.

Expectation and concern were that COVID-19 will add to the other agents that cause respiratory infection in children and in some cases possible coexistence(5). Although we estimated that the suspension of the school calendar, the measures of population isolation, the acquisition of hygienic practices by the general population, were positive factors to reduce the incidence of infection in the youngest, we did not predict this degree of impact.

In the months of March, April, and part of May in Paraguay, there was the confinement of adults and children, which justifies a minimal seasonal viral transmission evidenced by the absence of consultations for respiratory syndromes. In mid-May, the adults resumed their work activities (phase 3) and we saw a slight increase in asthma and pneumonia. However, patients with bronchiolitis remained rare and generated little pressure on the system. Winter is not over yet and we ask ourselves: is its appearance only delayed?

The pronounced decrease in seasonal acute respiratory diseases in PEM seems to be explained simply by the suspension of classes. It is, then, necessary to evaluate interventions to be implemented from now on in schools to reduce the transmission of respiratory viruses during the winter that is not only focused on reducing that of SARS-CoV-2.

Classes were suspended to prevent the transmission of Covid-19 between children and from them to their caregivers. Current evidence suggests that they may not be large transmitters as initially thought9and that the severity of the disease in pediatrics is much less than in adults10,11.

Important communication campaigns were carried out to produce habit changes in the population and measures and interventions have been demanded to reduce contagion in public places. Wouldn't it be an understandable approach for the future to carry out prevention efforts aimed at reducing the impact of the transmission of seasonal respiratory viruses to protect the little ones and those with special risk conditions?

On the other hand, consultations for simple colds also imply a high healthcare burden on our service. Educating the population on how to deal with mild and self-limited pathology is part of a medical literacy that will make it possible to direct resources to the care of the most serious patients. Learning about these changes in attendance could offer an opportunity to find alternative ways to support families outside of SEP in the future12.

This epidemiological situation forced us to make changes and investments at the health level. It is therefore necessary to develop a model for pediatric emergency care that is not the same as the pre-pandemic period. It is an opportunity for improvements in triage, infrastructure, health education for the population, and the application of telemedicine to represent advances that are sustained over time.
