Improvement of asymptomatic carriers and COVID-19 patients.

CT imaging	Improvement
	Asymptomatic (n = 19)	COVID-19 (n = 27)
Reduced lesion extent	10 (52.63)	24 (88.89)	7.60	0.008
Reduced lesion number	0	0	—	—
Reduced lesion extent and number	7 (36.84)	3 (11.11)	4.34	0.07
Decreased lesion density	14 (73.68)	21 (77.78)	0.10	1.00
