Computed tomography manifestations and prognosis of mild COVID-19 cases

ABSTRACT

Computed tomography (CT) manifestations of asymptomatic patients with familial cluster transmission and of patients progressing from mild to common type are compiled in this chapter. Holding on to the thought that the imaging findings of asymptomatic infection and mild cases can be negative, we point out the fact that asymptomatic infection cases refer to individuals with positive nucleic acid results from respiratory tract specimens while with no reported symptoms or clinical signs recognized. Having said that, we emphasize asymptomatic infection is highly contagious through illustrating how the SARS-CoV-2 virus carried by an asymptomatic patient spreads into his family. Mild COVID-19 cases are infection cases with mild clinical symptoms and negative imaging findings. Some patients with mild type turned into the common type as the disease progressed, the CT manifestations of these cases are demonstrated.
