Neocoronaviruses survive in the air for longer periods of time, and neocoronaviruses can survive in the air for more than a few hours after being removed from their hosts. When a patient with novel coronavirus is present in a space, healthy people who are present in that space within the next four to five hours may become infected with the novel coronavirus, and this group of people is known as a space contact. The novel coronavirus is a highly transmissible virus. If there is a history of indirect or direct contact with the virus, it is important to report it in a timely manner and follow the rules of quarantine so that group infections can be effectively avoided.
