In the largest study to date, Chinese scientists gave a detailed description of the spread of the new coronavirus infection. They calculated the incubation period of the disease, estimated the rate of spread of the epidemic and the infectivity of the virus. Their work is published by the New England Journal of Medicine. The period from infection with a new coronavirus to the onset of symptoms is 5.2 days on average, but can vary significantly from patient to patient. These estimates confirm that a 14-day quarantine recommendation for potential infected is warranted. According to the latest data from the World Health Organization, the incubation period for new coronavirus pneumonia is 2 to 20 days. Based on data on 425 cases of the disease, scientists have established the main characteristics of the current epidemic of new coronavirus pneumonia. According to their results,the number of cases is doubling every 7.4 days. Scientists have found that one patient with new coronavirus pneumonia infects an average of 2.2 people. This is called the maintenance factor (R0). For seasonal flu, it is about 1.3, for measles, 12 and above. The R0 factor of the new coronavirus is comparable to that for acute severe respiratory syndrome during the 2002-2003 epidemic. The transmission of the new coronavirus from person to person, according to new data, has been occurring since mid-December 2019.The R0 factor of the new coronavirus is comparable to that for acute severe respiratory syndrome during the 2002-2003 epidemic.
