An analysis on cure time of patients with COVID-19

Objective: To analyze the cure time from diagnosis to cure of coronavirus disease 2019(COVID-19) Methods: Based on the time of admission, diagnosis, and discharge of cured cases announced by the provincial and municipal health committees, the average period from diagnosis to discharge was calculated And based on the aggregate data including the cumulative number of diagnoses, the number of curedcases and the number of deaths and their proportional relationship, we calculated the cure time Results: The cure time curve of 580 COVID-19 patients had skewed distribution, with a skewness of 1 09, a mean cure time of (14 6±6 7) days, a median of 13 days, and a 95% confidence interval (6 9, 21 0) The average cure time calculated based on the relationship between the cumulative number of diagnoses, the number of cured cases and the number of deaths was (13 3±3 5)d, with a median of 13 5 d The average value of the cure time calculated based on the proportion of cured cases to the number of endpoints was (14 2±4 2)d, with the median number of 14 5 d Based on the calculation of the relationship between the cumulative number of diagnosed cases, the number of cured cases and the number of deaths, the median cure time of cases with COVID-19 in Wuhan, Hubei Province, and the whole country was 15 days, 15 5 days and 15 days, respectively The mediancure time for COVID-19cases in Wuhan, Hubei, and the whole country was 14 days Conclusion: The median cure time of COVID-19 is 13-15 5 days There is some variation at different time of the outbreak, but there is not much difference between different regions
