Abstract
To explore the epidemiological characteristics of COVID-19 associated with SARS-Cov-2 in Guizhou province, and to compare the differences in epidemiology with other provinces. The data were extracted from National Health Commission of the People's Republic of China, Health Commission of Guizhou province, and Health Commission of Hubei province from January 20 to February 12, 2020. Information included such as general demographic indicators, population data and clinical outcome. A total of 135 cases were analyzed in the study. The average age was 39.46±18.95 years. The ratio of males to females was 0.985:1. Most of COVID-19 patients were 18-45 years old (52.27%). Close contact history was the most common (37.88%), followed by residence history in Hubei (34.85%). There was no difference between males and females in age (P=0.953) and exposure condition (P=0.186). Correlation analysis showed that there was a significant positive correlation between the migration index and the number of confirmed cases (r=0.816, P=0.007). Among the cases, most patients were young adults. Most epidemiological characteristics were no difference between males and females. Family-based transmission should not be ignored, as a close contact history was the top reason of exposure. Moreover, population movements also had significant impact on outbreaks.
Highlights
Coronaviruses can cause zoonotic diseases, mainly severe respiratory infections in human[1], which can be excreted through respiratory secretions, transmitted through oral fluids, sneezing, and contact, and transmitted through air droplets
The World Health Organization (WHO) announced that the official name of the disease caused by the virus was COVID-19.9
We investigate the epidemiological characteristics of 135 patients confirmed to have SARS-CoV-2 infection, aiming to test whether SARS-CoV-2-infected patients may have different epidemiological characteristics than patients in other provinces, and provide an insight into the prevention and control of COVID-19 across China and even other places in the world
Summary
Coronaviruses can cause zoonotic diseases, mainly severe respiratory infections in human[1], which can be excreted through respiratory secretions, transmitted through oral fluids, sneezing, and contact, and transmitted through air droplets. The etiology of the unknown pneumonia was “2019 novel coronavirus (2019-nCoV)” named by the World Health Organization (WHO) on January 12, 2020. It possibily was associated with wild animals from the seafood market in Wuhan where most of patients were exposed.[3,4,5,6] human-to-human transmission has been responsible for most of the infections, including among health care providers.[4,5,6] the 2019-nCoV has spread rapidly to different parts of China and at least 26 other countries.[7] the dramatic increase in the number of cases has caused widespread panic. The WHO announced that the official name of the disease caused by the virus was COVID-19.9
