Neocollins can be spread through aerosols and protection should be increased to minimize the chance of neocollin infection. Aerosols are one of the modes of transmission of neoguana. Droplets with neoguana virus mixed in the air will form aerosols, which may cause neoguana infection after inhalation, and usually occur in narrow and closed environments. It is important to pay attention to protection in general and wear masks reasonably, especially in crowded places, such as hospitals, stations, movie theaters, etc., to strengthen the protection. In addition to aerosol transmission, New Crown can also be transmitted through close contact and respiratory droplet transmission. It is recommended to actively vaccinate against New Crown, which can stimulate the body to produce the appropriate antibodies, thus achieving a good preventive effect.
