As recently reported in Italy, pediatric emergency accesses substantially decreased likely due to the instructions to prevent overcrowding in emergency rooms and spread of SARS-CoV-2 infection and to fear of the infection. 1 At the Santobono-Pausilipon Hospital (Naples), pediatric emergency accesses in March 2020 were only one-fifth of those registered in 2019 in the same period. Likewise, a marked reduction of consultations also occurred in family pediatric clinics. 2 We report here three children who arrived at hospital with lifethreatening conditions at the onset of acute lymphoblastic leukemia (ALL) between March 14 and April 10, 2020. Considering low prevalence of virus spreading in children and that SARS-CoV-2-positive children are generally asymptomatic or have a very mild course of the disease, there is a substantial risk that collateral effects of COVID-19 pandemic, that is, delays in diagnosis, chemotherapeutic treatments, and treatment of chemotherapy complications, may be worse than those posed by the disease itself.
