It has been found that the novel coronavirus in Wuhan outbreak is a beta genus coronavirus and comes from wildlife, but the exact wildlife species has not been determined. Since bats are the natural host of most coronaviruses, and other evolved groups of novel coronaviruses are found in all types of bats. Therefore, researchers hypothesize that the novel coronavirus outbreak in Wuhan is most likely to originate from bats. In addition, analysis of available epidemiological data confirms that the virus can be transmitted continuously from human to human, with droplet and contact transmission being the main routes of transmission.
