Rumor identification: The disease pathogen is a new coronavirus, not SARS virus. Rumor analysis: 1. The pathogen causing the disease was identified as a new coronavirus. Coronavirus is a large group of viruses known to cause diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Some studies have shown that the novel coronavirus is similar to SARS coronavirus in the receptor binding pathway, but the genome sequence of the novel coronavirus (2019-nCoV) is also very different from that of SARS-CoV and can be considered as a novel virus. 2. In addition, compared with SARS virus, the novel coronavirus achieved the various stages of transmission from wildlife to human to limited human-to-human transmission in less than one month, indicating its relatively strong transmission. Thus, although the novel coronavirus has structural similarities to SARS virus, it is not a SARS virus. Special tips: Since current studies show that the novel coronavirus is different from the SARS virus and is more transmissible, it is necessary to take protective measures by wearing a mask when going out on weekdays and staying out of crowded places; maintaining hand hygiene; covering sneezing or coughing with tissues as much as possible; and paying attention to personal and household hygiene so as to better prevent infection by the virus.
