Summary

The investigators will first examine the impact of the COVID-19 pandemic on childhood cancer patients in Sweden and Denmark, both regarding susceptibility to severe COVID-19 among long-term childhood cancer survivors, and, for those diagnosed with childhood cancer during the pandemic, whether the path through primary care to cancer diagnosis as well as short-term survival has changed. Second, the investigators will study childhood cancer incidence before, during and after the pandemic with the particular aim to test the hypothesis regarding an infectious disease etiology for acute lymphoblastic leukemia.
