BACKGROUND Coronavirus disease 2019(COVID-19)is a serious infection caused by the new coronavirus severe acute respiratory syndrome coronavirus 2.The disease was first identified in December 2019 and has caused significant morbidity and mortality worldwide.AIM To explore the clinical characteristics and treatments for COVID-19 in the Qinghai-Tibetan Plateau Area in China.METHODS We retrospectively analyzed the blood cell counts(neutrophils and lymphocytes),blood gas analysis,and thoracic computed tomography changes of patients from Qinghai Province before,during,and after treatment(January 23,2020 to February 21,2020).In addition,we summarized and analyzed the information of critical patients.All data were analyzed using SPSS 17.0(SPSS Inc.,Chicago,IL,United States).The quantitative and count variables are represented as the mean±SD and n(%),respectively.RESULTS The main symptoms and signs of patients with COVID-19 were fever,dry cough,cough with phlegm,difficulty breathing,and respiratory distress with a respiration rate≥30 times/min,finger oxygen saturation≤93%in the resting state,and oxygenation index less than 200 but greater than 100(after altitude correction).Eighteen patients with COVID-19,of whom three were critical,and the others were in a mild condition,were included.The main manifestations included fever,dry cough,and fatigue.Three patients developed difficulty breathing and had a fever.They were eventually cured and discharged.Adjuvant examinations showed one case with reduced white cell count(6%)(<4×10^(9)/L),six with reduced count of lymphocytes(33%)(<0.8×10^(9)/L),and one with abnormal blood glucose level.All 18 patients were discharged,and no death occurred.CONCLUSION Our findings provide critical insight into assessing the clinical diagnosis and treatment for COVID-19 in the Tibetan plateau area.
