The association between domestic train transportation and novel coronavirus (2019-nCoV) outbreak in China from 2019 to 2020: A data-driven correlational report

Epidemiological and clinical features of 2019-nCoV acute respiratory disease cases in Chongqing municipality, China: a retrospective, descriptive, multiple-center study

“…Person-to-person transmission of COVID-19 in hospital and family settings is reported to be accumulating 3 Recently, there are some studies demonstrating the clinical characteristics and epidemiology of COVID-19 patients in Wuhan or throughout China [5][6][7][8] . As Chongqing is reported to be one of the major cities imported passengers from Wuhan in China from December 16, 2019 9 . Given the regional disparity of COVID-19, we aim to describe epidemiological, clinical, laboratory, and radiological features, treatment, and prognosis of COVID-19 patients in Chongqing municipality, and compare the differences between non-severe and severe patients, which may unravel risk factors associated with 28-day mortality and further suggest a specific therapeutic intervention for patients with COVID-19 in Chongqing municipality, China.…”

Quantifying the association between domestic travel and the exportation of novel coronavirus (2019-nCoV) cases from Wuhan, China in 2020: a correlational analysis

“…1 Wuhan locates in the centre of mainland China with a population of 14 million and is very conveniently connected to other parts of China through airlines and highspeed rails. 2 As of 31 January 2020 (5:00 p.m., GMT + 8), there were 9809 confirmed 2019-nCoV cases in mainland China, including 213 deaths and 180 discharges. 3,4 Cases infected in Wuhan were also detected in many foreign countries or regions including Thailand, Japan, Republic of Korea, the United States, Canada and some European countries.…”

“…The likelihood ratio (LR) test was adopted to justify the model structure in Equation (1) against the baseline form in Equation (2). For the delay term (τ ), it was expected to be equivalent to the incubation period, which was reported to be 5.2 days (95% CI: 4.1-7.0) in.…”

Going global – Travel and the 2019 novel coronavirus

“…After the first cases in Wuhan, Hubei province, the growth of the outbreak was predictable nationally and internationally.
