Novel coronavirus refers to the new coronavirus, which is generally susceptible to the population, and there is no such thing as obese people being more susceptible to the new coronavirus. The new coronavirus is a new strain of coronavirus that is contagious and can be transmitted through respiratory droplets and close contact, and in relatively closed environments, it can be transmitted through aerosols. The new coronavirus is generally susceptible to the population, and the chance of contracting the new coronavirus is higher if there is no proper prevention of the new coronavirus in the daily life. It is recommended that people who are eligible for the new coronavirus vaccination should receive the new coronavirus vaccine in time to prevent the new coronavirus effectively. Wearing a surgical mask when going out and keeping a certain distance from others and not having close contact with others can reduce the chance of contracting the new coronavirus.
