Since December 2019, some unexplained pneumonia situations have already been reported in Wuhan, China. transported and epidemic away etiological research. January On 12?2020, the Globe Health Company (WHO) tentatively named this new trojan seeing that the 2019 book coronavirus (2019\nCoV). January On 30?2020, WHO announced the 2019\nCoV epidemic a community health crisis of international concern. February On 11?2020, the WHO formally named the condition triggered by 2019\nCoV seeing that coronavirus disease 2019 (COVID\19). On a single time, the coronavirus research band of the International Committee on Taxonomy of Infections called 2019\nCoV as severe acute respiratory syndrome coronavirus 2 (SARS\CoV\2). On 23 February?2020, there were 77?041 confirmed instances of SARS\CoV\2 infection in China. The number of infections offers exceeded that of the SARS outbreak in China in 2002. 1 , 2 purchase CC 10004 To help healthcare workers around the world to better deal Mouse monoclonal to CD21.transduction complex containing CD19, CD81and other molecules as regulator of complement activation with the SARS\CoV\2, we review the relevant published papers on COVID\19 to provide a research for future COVID\19 study. 1.1. Sources of SARS\CoV\2 SARS\CoV\2 is definitely a coronavirus and belongs to the \coronavirus cluster. COVID\19 is the third known zoonotic coronavirus disease after SARS and the Middle East respiratory syndrome (MERS). SARS\CoV and purchase CC 10004 MERS\CoV also belong to the \coronavirus cluster. 3 Zhu et al 4 confirmed that SARS\CoV\2 was a new \coronavirus belonging to the subgenus botulinum of Coronaviridae. According to the current data, 5 the early COVID\19 cases were related to the Huanan seafood market, and the possibility of human being\to\human being transmissions could not be ruled out. The WHO statement claimed the SARS\CoV\2 could be detected in the environmental samples collected from your seafood market, but it has not yet been identified if a specific animal species bears the SARS\CoV\2. A study by Ji et al 6 showed the SARS\CoV\2 was a chimeric disease between a bat coronavirus and a coronavirus of unfamiliar origin. By comparing with other animals, they found that snakes are the most likely wildlife repository for the SARS\CoV\2. 6 The research by Benvenuto et al 7 showed that the SARS\CoV\2 was purchase CC 10004 only closely related to the coronavirus isolated from Chinese chrysanthemum\headed bats in 2015. Their research supported the theory that the transmission chain started from bats to humans. Chan et al 8 and Hui et al 9 confirmed that SARS\CoV\2 was a new coronavirus closely related to the bat SARS\CoV. Recently, Zhou et al 10 and Wu et al 11 found that the sequence homology between SARS\CoV\2 and SARS\CoV was 79.5%. They also found that the SARS\CoV\2 had high homology with bat coronaviruses. Therefore, the current evidence strongly supports that the SARS\CoV\2 was derived from bats, although the intermediate hosts of SARS\CoV\2 remain to be determined. 1.2. Epidemiological characteristics of COVID\19 A study by Wang et al 12 showed that from January 10 to 24, 2020, the number of people diagnosed with the SARS\CoV\2 infection in China increased by 31.4 times. On 23 February?2020, the number of people diagnosed with COVID\19 in China was 1879 times of that on 10 January?2020. They estimated the case fatality rate of COVID\19 to be 2.84% based on their patient pool. The authors also found that the ratio of male to female deaths was 3.25:1, the median age of death was 75 years, the median time from the first symptom to death was 14 days, and the median time from early symptoms to death in people aged 70 or older (11.5 days) was shorter than that in people under 70 years old (20 days). These findings suggest the disease may progress faster in the elderly than in the young. A study by Li et al 5 showed the median age of 425 patients infected with SARS\CoV\2 was 59 years, of which 56% were males, purchase CC 10004 the average incubation period was 5.2 days, and almost half of the adult patients were 60 years old or older. In the early stages, the number of infected.
