effects of coronavirus on respiratory system ​

Answer 1

Explanation:

Human coronavirus (HCoV) accounts for 15-30% of common colds, but only one case report has described the effect of a coronavirus infection, that was asymptomatic, on human respiratory epithelium. The authors examined the effects of infection with HCoV on ciliary structure and function in healthy volunteers infected by intranasal inoculation with HCoV 229E.
