Abstract: Objective To determine the epidemiological features of major vector?borne diseases from 2006 to 2012 in Guangzhou, China and provide a scientific basis for the prevention and control of vector?borne diseases. Methods The basic information of cases of major vector?borne diseases reported in Guangzhou from 2006 to 2012, as well as the epidemiological information of surveyed cases, was collected from the National Disease Surveillance Information Reporting System. The descriptive epidemiological method was used to analyze the epidemiological features of major vector?borne diseases in Guangzhou. Results A total of 5828 cases of six vector?borne diseases were reported from 2006 to 2012 in Guangzhou. The average annual incidence rates of hemorrhagic fever with renal syndrome (HFRS), dengue fever, leptospirosis, malaria, Japanese encephalitis (JE), and scrub typhus were 1.01/100 000, 1.37/100 000, 0.10/100 000, 0.18/100 000, 0.02/100 000, and 4.72/100 000, respectively. The incidence of dengue fever and scrub typhus had marked seasonal characteristics. HFRS and dengue fever were mainly incident in the central urban area, while leptospirosis, malaria, JE, and scrub typhus occurred mainly in the suburban and rural areas. JE occurred mainly in children, while other vector?borne diseases had a wide occupational distribution and were mainly seen in the middle?aged and elderly. Conclusion The incidence of vector?borne diseases in Guangzhou was relatively stable, but with a slight upward trend in recent years, and the risk still exists. The surveillance and control of vector?borne diseases should be strengthened.
