Reported Vector-Borne Diseases — China, 2018

Abstract

Introduction: Vector-borne diseases are an important type of infectious disease in China. This study aims to present a summary of vector-borne diseases reported in China in 2018 to provide information on their control and prevention. Methods: A descriptive analysis was utilized to explore the epidemiological characteristics. Results: A total of 51,599 cases with vector-borne diseases were reported in 2018 with an incidence rate of 3.69/100,000. Scrub typhus, hemorrhagic fever with renal syndrome (HFRS), and dengue contributed to 85.08% of all the cases. A total of 377 fatalities were included with a case fatality rate of 0.73%. Japanese encephalitis (JE), severe fever with thrombocytopenia syndrome (SFTS), and HFRS accounted for 95.76% of all fatalities. Different vector-borne diseases show disparities in gender, age groups, seasons, and regions. Conclusions and Implications for Public Health Practice: In 2018, vector-borne diseases caused substantial morbidity and mortality in Mainland China with heterogeneity in populations affected and geography. Different regions should adopt targeted strategies and measures according to vulnerable populations and diseases.
