In the initial phase of the Sars-Cov2 pandemic they seemed to be immune to it, then they too, the smallest, began to be infected, although with a less severe course – apart from rare exceptions – of the disease.
Under three years old – The first significant data highlighted by the research is the reduced incidence of cough. Contrary to what was thought in the first months of the pandemic, it is the cold the most common symptom under the age of three. Almost 20% of the children followed have had it. Cough (just over 15%) and fever follow. Pediatricians have reported that the rise in body temperature, specifically above 38 °, is actually less frequent than expected.
Above three years – In this age group, the most common onset symptom is headache (it affected more than 16% of the young patients), followed almost equally by the cold and then by the fever (just over 14%). Coughing only occurred in just over 12% of the children.
Chronic diseases – the study confirms – they do not seem to influence the possibility of having a positive diagnosis while the trend of infections in children varies greatly according to the region and family members are more frequently infected.
I study – The research was attended by 34 family pediatricians who followed 1,947 children with a regional distribution concentrated in some areas: Veneto (10 pediatricians, 10,283 children), Lombardy (8, 7,390), Piedmont (6, 5,967), Sicily (4, 3,675). The other regions involved were Campania (2 pediatricians, 1,827 children), Friuli, Puglia, Emilia-Romagna and Lazio (1 pediatrician per Region with 1,108, 1,050, 990 and 889 children respectively). The overall incidence of disease cases in the followed population was 3.8 cases per thousand children in a month, with significant differences between the Italian regions.
L’Emilia Romagna e Veneto are the most affected regions. “These differences are probably related to the different management of the disease in the various regions, resulting in a different possibility of confirming the diagnosis in suspected cases”, explained Giacomo Toffol, Acp pediatrician and coordinator of the study, on which pediatricians among others worked. and researchers Laura Reali and Roberto Buzzetti.
Admissions and course – Pediatricians confirm that, in general, the course of the disease in the pediatric age is confirmed to be significantly less severe than in the more advanced ages, with a low number of hospitalizations and a very low mortality. But while the trend of pediatric Covid-19 cases requiring hospitalization has been widely described by numerous Italian and international studies, there is less information relating to the much greater number of less serious pediatric cases, which do not require hospitalization. hospitalization. Furthermore, the information on the contagiousness of the Sars-Cov2 virus in this age group and on the role that children and adolescents play in the transmission of this virus is still not exhaustive.
