Key message

A doença COVID-19 parece causar quadros benignos em crianças por razões ainda desconhecidas, não sendo claro se crianças com doenças crónicas ou imunocomprometidos também terão uma evolução favorável. Recomenda-se, se possível, o aleitamento materno mesmo em caso de infeção da mãe - não há evidência de que o vírus passe ao leite materno mas os possíveis anticorpos presentes podem ser benéficos. As medidas preventivas são fundamentais para evitar o contágio.

Abstract

With a mortality rate of 2–3% and a transmissibility rate (R0) of 2–3, the COVID-19 virus outbreak is spreading rapidly worldwide and is the new foe. The first cases in Wuhan, China, did not involve children, which suggested that the disease was not symptomatic in children [1]. Now that the outbreak is global with more than 90,870 confirmed cases and 3112 deaths (as of March 3, 2020) [2], we can evaluate more accurately the epidemiology of this disease. There are more than 900 confirmed pediatric cases, but currently no child under 10 years of age has died; only one individual between 10 and 19 years of age died [3], [4], [5], [6] and only one child under 1 year old was reported to have a severe form of the disease [7]. Most of the children were infected after exposure to an adult from the household [4]. These data suggest that children seem to have been spared the major impact of COVID-19 virus.
