Duration of COVID-19 in HED patients with or without antibodies that block binding of the SARS-CoV-2 spike protein to its receptor ACE2. Sera from individuals with HED and SARS-CoV-2 infection (triangles, n = 15, age 9–52 years) and from control subjects of the same age group who had been exposed to SARS-CoV-2 (squares, n = 38) were investigated for specific spike-blocking antibodies against this virus. If such antibodies were present, the duration of primary COVID-19 symptoms (fever, head and body ache, diarrhea, exhaustion, cough, shortness of breath, and chest tightness) was similar to that of control subjects. In the absence of spike-blocking antibodies against SARS-CoV-2, however, the course of COVID-19 was often remarkably long
