  1. List of symptoms mentioned in 38 initial phone calls to emergency medical services. Thirteen calls were to the emergency call center 112, while 25 were to the medical helpline 1813. For any symptom, it was registered in how many calls the symptom was present and in how many calls the symptom was asked about and/or mentioned. Because symptoms were not always asked about, p-values are presented for both symptom present in cases asked about that symptom and symptom present in all cases. There was no difference between children and adults in symptoms present of symptoms asked about, but of all cases, children more often presented with fever and rash/petechiae than adults
