Abstract

Abstract

Objective To explore the epidemiological characteristics of confirmed cases of coronavirus diseases 2019 (COVID-19) in Puyang, Henan Province, so as to provide basis for diseases control and preventive. Methods The epidemiological data of 17 cases of COVID-19 in Puyang were collected, and the time, regional and population distribution characteristics of COVID-19 were described and analyzed by drawing disease sequence diagram and case relationship diagram. Results Among the 17 cases, 7 were male (41.2%); the median age was 36 years old with age ranged from 12 to 66 years. A total of 4 clustered outbreaks occurred, involving 12 cases (70.6%), all of which were family recurrent cases. The median incubation period was 6.5 days, the shortest 3 days and the longest 13 days. The onset time of a second-generation case was 11 days earlier than that of the indicator case. The median time between onset and treatment was 4 days, the shortest was 0 days and the longest was 12 days. Of the 17 cases, 6 had a sojourning history in Hubei Province within 14 days, and 1 had a history of overseas tourism. The other cases were all local infections, 8 of them were close contacts of the confirmed cases, and 2 of them were from unknown sources. Among the close contacts, the cases involved in the family clustering epidemic were transmitted through close contact and respiratory tract. After detailed investigation and inquiry, it was inferred that the transmission route was the staircase droplet transmission. Conclusion In Puyang City, most of the cases were from Hubei Province, and was dominated by family clustering epidemic. There was a possibility of infection in the incubation period.
