Rumor identification: The new coronavirus is not a SARS virus. Rumor analysis: 1, genetic sequencing is different: the new coronavirus and SARS virus genome sequence similarity of 80%, but the gene sequence differences are still large, so it is not the SARS virus “evolutionary version”, but a new virus. 2. Different spreading power: Compared with SARS virus, the new coronavirus achieves the various stages of transmission from wild animals to people, to limited human-to-human transmission, and then to human-to-human transmission in less than a month, indicating its stronger spreading power. 3, the severity of symptoms are different: patients infected with the new coronavirus can develop severe respiratory failure, compared with the SARS virus infection, the patient’s respiratory failure progresses faster, and the patient’s heart is more attacked, making it more difficult to save. Special Note: Studies have shown that the new coronavirus is different from SARS virus and that it is preventable and controllable, so there is no need to be overly nervous or panic. However, since it is highly transmissible, the public needs to take certain protective measures, such as wearing a good mask, washing hands and disinfecting regularly, cooking food before eating, avoiding social gatherings, paying attention to personal and family hygiene, and paying attention to the smooth flow of sewerage and necessary disinfection, etc., in order to prevent the spread of the virus.
