| Summary: | Objective To analyze the epidemiological characteristics of novel coronavirus pneu-monia in Henan Province, and provide evidence support for the prevention and control of novel corona-virus pneumonia.Methods Collected information on cases of novel coronavirus pneumonia from the Health Commission of Henan Province or other official media, and used descriptive statistical methods to analyze the epidemiological characteristics of the occurrence and development of novel coronavirus pneumonia in Henan Province.Results As of February 7, 2020, the cumulative number of confirmed cases in Henan Province was 981, with a total of 20 928 close contacts and a total of 10 187 medical ob-servers. The patient's age was mainly concentrated in 19 to 60 years old, accounting for about 81.75%. The proportion of men with novel coronavirus pneumonia was slightly higher than that of women (54.09% vs. 44.58%). Fever is the main symptom of the novel coronavirus pneumonia, and nearly half of the patients are diagnosed within 3 days. 56.31% of patients with novel coronavirus pneumonia have a history of trav-elling in Wuhan, 24.23% and 8.63% of patients have a history of contact with a confirmed case and a his-tory of contact with a suspected case, and only 14.93% of patients received isolation observation before onset. Before diagnosis, 39.38% of patients did not see a doctor or had only one visit, and 57.74% of pa-tients lived in urban areas.Conclusion The majority of cases of novel coronavirus pneumonia in Henan Province are imported cases. The movement of people during the Spring Festival is the main factor af-fecting the development of the epidemic. The implementation of strict isolation policies can effectively control the development of the epidemic. |
