Therefore, it is still too early to judge the efficiency of these therapy, much more studies are still needed In summary, our study firstly demonstrated the regional disparity of COVID-19 in Chongqing and further thoroughly compared the differences between severe and non-severe patients in Chongqing municipality, China. The 28-day mortality of COVID-19 patients from 3 designed hospitals of Chongqing municipality is 1.5%, approximately consistent with the official fatality rate 0.91%, lower than that of Hubei province and mainland China including Hubei province. Early isolation, early diagnosis, early management, combined with the strong epidemic control in Hubei and the effective prevention of local cluster outside Hubei might collectively contribute to the marked reduced 28 day-mortality in Chongqing municipality.
