Epidemiological characteristics of imported infectious diseases in Guangzhou, 2005-2019

Objective To analyze the epidemiological characteristics of related infectious diseases in Guangzhou from 2005 to 2019, and to provide scientific basis for the prevention and control strategies and measures of travel-related diseases in Guangzhou. Methods The case information of acute infectious diseases was collected from the infectious diseases report information system of China Center for Disease Control and Prevention from January 2005 to September 2019, and combined with the clinical and doctors’ case diagnosis records, the three distribution characteristics of imported infectious diseases in Guangzhou were described. Results From 2005 to 2019, 1613 cases of imported infectious diseases were reported in Guangzhou. Dengue fever is 46.99% (758/1613) and malaria is 45.13% (728/1613) of the total imported cases. The imported cases were mainly male, accounting for 75.88% (1214/1613), and mainly Chinese, accounting for 75.57% (1219/1613), and the age was concentrated in the age group of 20 to 45 years old, accounting for 83.01% (1339 /1613). The top five occupations were workers (12.83%, 207/1613), housekeeper and unemployment (11.78%, 190/1613), cadres and staff (7.19%, 116/1613), students (4.15%, 67 /1613), and retirees (2.91%, 47/1613). The number of imported cases increased from May every year, peaking in August and September, and declining rapidly after October. The main source areas of import are other countries in Asia and Africa. Conclusion Dengue fever and malaria are the main types of imported infectious diseases in Guangzhou. The cases are mainly Chinese, male, young adults and workers. We should strengthen intervention and health education according to the characteristics of the infected population, and do a better job in the prevention and control of imported infectious diseases.
