There is no uniform definition of superspreaders, and according to the World Health Organization’s definition of SARS superspreaders back then, it refers to instances in which an infected person infects more than ten people, and most of these superspreaders are elderly people with long-term illnesses or chronic diseases such as diabetes and kidney disease. To determine whether a patient is a superspreader, complex factors such as the mode of action of the pathogen and the disease, the environment, and the patient’s activity during a limited period of time need to be considered, and these factors cannot be judged by the number of infections alone. When immunocompromised individuals are infected with novel coronaviruses, the virus replicates in their bodies more often than in the general population and can easily infect more people around them, even if they reduce their contact with others. In addition various symptoms of infection may also promote the spread of the virus, such as coughing and sneezing, which are the main ways of virus transmission.
