Dengue Fever Breeding Sites Elimination and Control

Dengue fever, commonly known as tengu fever or broken bone fever, is a tropical infectious disease that transmits dengue fever virus through vector mosquitoes. The vector mosquitoes that transmit dengue fever in Taiwan are Aedes albopictus and Aedes aegypti. There were many large-scale epidemics before World War II. But due to the joint efforts of the government and the public, Taiwan is no longer a large-scale epidemic area of dengue fever. In recent years, due to immigration, the epidemic has been outbreaking again.

Taiwan locates in the subtropical region, and the temperature in summer is relatively high. In previous years, most Dengue Fever cases occurred after the beginning of summer (July and August). In recent years, due to global warming, the epidemic has a tendency to occur earlier (June) especially in the southern part of Taiwan where the annual average temperature can reach as high as 25°C, which is suitable for the growth of mosquitoes. Cases of Dengue Fever occur all year round, which shows that in Taiwan they may be inevitable, and the epidemic may even gradually move northward. The government noticed that Dengue Fever in the southern region lasts for a long time and the number of infected population is large. Therefore, environmental protection and health agencies have established a horizontal and vertical coordination mechanism to actively cooperate in the prevention and control of Dengue Fever.

According to the Law on the Prevention and Control of Infectious Diseases, Dengue Fever is a second-class statutory infectious disease, and the competent authority for epidemic prevention is the Ministry of Health and Welfare. The prevention and control work includes 7 main focuses: epidemic surveillance, vector investigation and research, medical treatment, inspection, publicity, spraying, and removal of breeding sources. The Department is cooperating with the Ministry of Health and Welfare to carry out the removal of outdoor breeding sources of Dengue Fever vector mosquitoes and simultaneous emergency spraying and disinfection work in the aforementioned projects.
