New coronavirus outbreaks spread quickly and rapidly, and many people are infected. New coronavirus infection is mainly respiratory transmission, such as respiratory droplet transmission. The onset of new coronavirus is winter and spring, especially when the outbreak occurs during the Chinese New Year, so the movement of people is very frequent. The transmission of the new coronavirus may be higher than the speed and ability of previous SASR and seems to be more infectious than SASR. Many patients develop the disease after returning home during the Spring Festival. The new coronavirus infection is characterized by a very high number of aggregated cases and a very high incidence within the family, which is related to the transmission and virulence of the virus itself because of its nature of respiratory transmission and the presence of other external factors, so it spreads quickly and more widely.
