Low Mortality Rate of Novel Coronavirus Pneumonia (COVID-19) - Outside of the Main Epidemic Area Wuhan

摘要

Objective: In December 2019, a new coronavirus is spreading in China at a faster pace. This paper focuses on the regional differences in mortality rate to provide useful references and suggestions for the prevention and control of 2019-nCoV pneumonia in other regions of the world. Material/Methods: Data resource: All date of cases In Yunnan Province was confirmed by the author. Another data came from the authority announcement which is update by hours. All data are beginning announced after January 29.2020 when WHO announces a new outbreak of coronavirus pneumonia as a public health emergency of international concern (PHEIC) at 4 a.m. on January 31.2020. Mortality Rate: All statistical analyses were made using SPSS13.0 for Windows software (SPSS Inc., Chicago). The data indicated are expressed as mean standard deviation. The t-test was used to compare the variables between groups. P-value greater than 0.005 was considered as statistically significant, Crude mortality ()=number of dead individuals per unit time/number of sicknesses per unit time 1000 . Results: As of 11:34 on April 16, 2020, In China, there were 83,797 confirmed cases, 63 suspected cases, Severe cases 95, 3,352 cases died, 78,504 cases were cured and 713,523 cases were released from medical observation. Hubei has reported 67,803 cases of new crown pneumonia (including 146 cases of clinical diagnosis), among which 50,008 cases (including 146 cases of clinical diagnosis) in Wuhan city, The oversea case is 1,426,071, and only 133818 case died. Crude mortality of Hubei is 47.52 (). The crude mortality rate of Hubei Province is significantly different from other provinces (P-value greater than 0.005). Conclusions: Recent COVID-19 case data show that there are not only more cases but also higher mortality rates in the source areas. It revealed a situation that the lack of medical resources and treatment capacity. Effective epidemic prevention can prevent such a situation. Paying attention to the treatment of light patients is conducive to their conversion into severe, and then reduce the mortality. Low mortality rate of Novel Coronavirus Pneumonia (COVID-19) outside of the main epidemic area Wuhan shows active medical treatment is the key to reduce mortality.
