Abstract

A 48-year-old woman, considered as a close contact of her husband who was diagnosed with COVID-19. She was clinically diagnosed with COVID-19-related pneumonia because of a positive antibody test. Her BALF contained an elevated lymphocyte fraction, which might explain why steroids are effective against COVID-19-related pneumonia.
