Abstract

Abstract

Objective To compare epidemiology characteristics and control measures of dengue fever (DF) outbreaks in public places in Shenzhen and Hong Kong and integrate the advantages for better response to DF outbreaks. Methods Data of DF cases and mosquito vector surveillance in Shenzhen and Hong Kong were collected for descriptive epidemiological analysis and measures of mosquito control were compared. Results A total of 19DF cases were recorded in 13 d among six districts of Hong Kong, the male: female ratio was 1:0.9. In Shenzhen, 20 cases were recorded in 33 d, the cases were distributed in three sub-districts, the Male: female ratio was 1:0.82; Age difference between Shenzhen and Hong Kong was statistically significant (Z=-2.855, P=0.004). The time interval between date of onset and laboratory confirmation ranging from 5.5 to 8.5 d (median: 7d) in Hong Kong, and ranged from 1.5 to 5.4 d (median: 2 d) in Shenzhen, the difference was statistically significant (Z=-3.818, P < 0.001). On the 4th day of the outbreak, Hong Kong declared 30 d closure for anti-mosquito operations with a range of 500 m, and monthly area ovitrap index (AOI) was used to monitor the territory-wide situation of Aedes albopictus. On the 2nd day of the outbreak, Shenzhen declared source closure for mosquito control with a range of 400 m and emergency vector surveillance was conducted, using Breteau Index (BI) and Human-baited double net trap(HDN) every 3 d. Conclusions The nature, scale, time and place of the two local DF outbreaks in Shenzhen and Hong Kong are similar. The prevention and control system is more sensitive and prompt, the ability of early detection is stronger, mosquito vector surveillance program is more comprehensive and the frequency is higher in Shenzhen. The epidemic information dissemination and risk communication with media is more active, mosquito management and control is more professional in Hong Kong.
