    Snakes could be the source of the Wuhan coronavirus outbreak
    By Haitao Guo, Guangxiang "George" Luo and Shou-Jiang Gao, The Conversation
    Updated 7:26 PM ET, Wed January 22, 2020

    (CNN)Snakes -- the Chinese krait and the Chinese cobra -- may be the original source of the newly discovered coronavirus that has triggered an outbreak of a deadly infectious respiratory illness in China this winter.

    The many-banded krait (Bungarus multicinctus), also known as the Taiwanese krait or the Chinese krait, is a highly venomous species of elapid snake found in much of central and southern China and Southeast Asia...


    • nCoV’s relationship to bat coronaviruses & recombination signals (no snakes)

      With Xiaowei Jiang at XJTLU we’ve carried out a preliminary evolutionary analysis to characterise the evolutionary origins of the Wuhan virus, nCoV. Focus of our analysis is on the Wuhan-Hu-1 virus (accession no. MN908947, released on GenBank by Shanghai Public Health Clinical Center and School of Public Health, Fudan University, Shanghai, China) as all nCoV cluster together so will share the same evolutionary ancestry. It’s clear from phylogenetic analysis the new human virus is most closely related to bat coronaviruses in the Betacoronaviruses genera. While this is apparent from both the previously reported BLAST and full-genome phylogenetic analysis the closest related bat viruses (CoVZC45 and CoVZXC21) are in fact recombinants with shared breakpoints either side of ORF1b:

      nCoV-recombination-analysis1528?1138 469 KB

      The phylogenetic clustering of the Wuhan-Hu-1 virus is consistently as a sister group to the SARS-related bat coronaviruses. Interestingly, a third bat coronavirus (Longquan_140) is a recombinant involving the Wuhan virus lineage in part of ORF1a.

      1680-3014692?540 50.6 KB

      This analysis has detected three bat coronavirus recombinants (two with shared breakpoints) involving the nCoV lineage indicating greater diversity in the Chinese Sarbecovirus group than previously appreciated. The clustering of the related Sarbecovirus viruses from Kenya and Europe suggest the Wuhan virus is still part of the Sabecovirus sub-genre, and these recombination events probably occurred in bats. Although. given the propensity of coronaviruses to switch hosts, involvement of another species cannot be discounted. There is also a very good chance that a non-bat intermediate species is responsible for the beginning of the current outbreak in Wuhan. Given the tight clustering of the nCoV viruses in phylogenetic trees it seems most likely one event has occurred.

      Several of these bat coronaviruses have been previously detected to be recombinant under-scoring the importance of doing appropriate analysis when analysing these viruses using phylogenetic methods. Recombination, in this case between divergent coronaviruses circulating in bats, violates our assumption of a single evolutionary tree and so needs to be considered carefully when inferring coronavirus evolution from complete genome alignments. We’re looking into the patterns of breakpoints to see if there’s any clues to the significance (or not) of these recombination events.

      We’d like to thank the researchers and health professionals for making the nCoV data available. Credit also needs to be given to the surveillance projects for generating the data that is now available for comparison and to the software developers for making the tools we’ve used freely available: FigTree, available at:; 9 GARD, available at 5; MAFFT, available at; 4 PhyML, available at; 5 and RDP4, available at 5.

                                On January 22, our province held a press conference on the prevention and control of pneumonia outbreaks of new coronavirus infections. As of 20:00 on January 22, Hubei Province has reported a total of 444 cases of pneumonitis infected by new-type coronavirus (from 00:00 to 20:00 on January 22, 69 new cases of pneumonitis infected by new-type coronavirus were newly added in Hubei Province, of which new (62 cases increased, 8 cases died; 6 cases increased in Jingzhou City, 1 case increased in Jingmen City), 28 cases have been cured and 17 patients have been discharged. At present, 399 patients are still being treated in the hospital, of which 71 cases are critically ill and 24 cases are critically ill. They are all under isolation treatment at designated medical institutions. A total of 2,556 close contacts have been tracked, 863 people have been released from medical observation, and 1693 people are still receiving medical observation.

                                Yang Yunyan, deputy governor and deputy commander of the provincial pneumonia prevention and control command of the new type of coronavirus infection, attended the press conference and introduced the province's prevention and control work.

                                Since January 2, the Provincial Party Committee and the Provincial Government have held a number of special meetings to analyze and determine the situation of the epidemic situation, and study the disposal of the epidemic situation. The provincial government has set up a leading group and a special working class to coordinate and dispatch the epidemic prevention and control work, to discuss daily and report daily to study and solve major problems. The Provincial Health and Health Committee and Wuhan Municipal Government established the frontline command for epidemic situation disposal, established a joint epidemic handling mechanism, and dealt with various specific problems in a timely manner. Save patients' lives first, focus on the best medical resources in the province, and organize medical treatment. From January 12, all confirmed cases in the hospital will be transferred to Wuhan Jinyintan Hospital for centralized treatment. Establish a provincial and municipal joint medical expert group to draw authoritative experts from Tongji Hospital, Xiehe Hospital, Provincial People's Hospital, and Zhongnan Hospital to take a responsible and responsible approach to strengthen the treatment of critically ill patients.

                                Under the guidance of the National Health Commission, it actively organized and implemented epidemiological investigations, specimen collection and inspection, source tracing, monitoring and analysis, and timely grasped the research and judgment and evaluation of virus mutations.

                                From January 14th, the temperature of passengers departing from Han will be tested at the airports, stations and terminals in Wuhan. "Daily disinfection" and "Ventilation per shift" of public transportation in the city. The South China Seafood Market will be closed for remediation from January 1st, and a centralized and specialized remediation of the Wuhan agricultural (market) market and various business establishments will be carried out to eliminate the relevant markets and the living environment of hospitals, patients and close contacts. Cumulative disinfection area is 304010 square meters. Wuhan launched a patriotic sanitary campaign in winter and spring with the theme of "renovating the environment, cleaning homes, and welcoming the festival". It cleared 309 tons of garbage, used 48,550 rodent control facilities, and put 860 kg of rat medicine.

                                In addition, our province also strengthened information disclosure and public opinion guidance. The situation report and authoritative interpretation were published on the official website of Wuhan Municipal Health and Health Commission, and the epidemic situation information was released on a regular basis. The mainstream media, new media, and self-media are used to continuously publish health science popularization knowledge and improve the people's awareness of self-protection.

                                At present, the situation of epidemic prevention and control in our province is still very grim. The number of confirmed cases in Wuhan has increased rapidly, and confirmed cases have been reported in many places inside and outside the province. The virulence of the virus still needs to be continuously observed and evaluated, and the infectivity is still uncertain. In addition, the Spring Festival is approaching and the dense movement of personnel does not rule out the possibility of a continuous increase in the number of cases and outbreaks. The situation is changing rapidly, which brings great challenges to prevention and control.

                                According to the decision-making and deployment of the Party Central Committee and the State Council, our province has comprehensively strengthened the ideas, strategies and measures for the next step of epidemic prevention and control: the establishment of the provincial pneumococcal infection prevention of new coronavirus infection by the provincial party committee and the chief person in charge of the provincial government. Control headquarters, set up special classes to comprehensively coordinate the prevention and control of the epidemic situation; initiate the second-level response to public health emergencies in the province, and establish prevention and control leadership agencies in various places to mobilize all-out; in accordance with "law, regulations, territorial management, The principles of improving the mechanism, responding reasonably, relying on science, being powerful and effective, being open and transparent, and seeking truth from facts, and implementing internal non-proliferation and external prevention export measures.
