Coronavirus (COVID-19) Collection
- At present, approximately 10–20% of COVID-19 patients need medical treatment in hospitals, and approximately 5% need long-term treatment in intensive care units (ICU). The majority of COVID-19 patients can be managed in an outpatient setting. Known important risk factors are age, male gender, high body mass index and pre-existing chronic conditions (Jordan et al., 2020). However, young and seemingly healthy individuals are also at risk to die from COVID-19 infections. At present, this heterogeneity of the disease course is not well understood.
- The coronavirus disease 2019 (COVID-19) pandemic has affected millions of people worldwide. In contrast to many other infectious diseases, children have diagnostic findings similar to adults, but fewer children seem to have developed severe pneumonia (Ludvigsson, 2020). At present, this phenomenon is not well understood. One of several explanations might be that other infections that are frequent in childhood are protective against a severe course of COVID-19.
