[INTERNATIONAL COOPERATION IN PEDIATRIC RHEUMATOLOGY IN THE CORONA ERA].

Following the appearance of the corona pandemic, international cooperation in pediatric rheumatology regarding registry of patients with rheumatic disease who have corona was launched within a few days. The parents' association initiated a similar patients' oriented registry. Following a large data collection showing that corona morbidity is low among children with rheumatic diseases, we could publish more evidence-based guidelines for physicians and patients. A similar registry for patients with hyper-inflammatory syndrome was also launched. The usage of telemedicine increased during that period.
