The source of weihai epidemic

Due to frequent population movements and the approach of the Spring Festival, the number of people returning from other places to visit relatives has increased dramatically. Novel coronavirus was introduced into Weihai by plane, road and train. In particular, the K 1068 train from Hankou Station to Weihai Station, from Hubei epidemic area to Weihai, has a considerable number of imported cases. Due to the poor ventilation and long driving time of the train, when there is a source of infection on the train, the transmission risk is extremely high. Epidemiological investigation shows that the cases on this train and their follow-up cases account for more than half of the total cases in our city.
