Nearly 40,000 cases of dengue fever have been diagnosed in Vietnam this year, and the epidemic spread rapidly in the northern region.

　　Xinhua News Agency, Hanoi, July 12 (Reporter Sun Yi) According to the report of the Vietnamese Ministry of Health on the 12th, in the first half of this year, nearly 40,000 cases of dengue fever were diagnosed and 8 cases died in Vietnam. Since the beginning of this year, the epidemic situation of dengue fever in Vietnam has eased compared with last year, but it has just entered the high-incidence season of dengue fever and the epidemic has spread rapidly in the north of the country.

　　Ruan Wenyong, director of the Insect Research Office of the Central Institute of Malaria, Parasitology and Entomology in Vietnam, told the media that more than 1,100 cases of dengue fever were diagnosed in northern Vietnam in the first half of the year, an increase of 60% over the same period last year. The worst epidemic is in ha noi, where 823 cases of dengue fever have been confirmed this year, nearly 3.5 times the number of confirmed cases in the same period last year, but no deaths have occurred. The main reason is that the weather in ha noi is abnormal in recent days, and the rainfall after high temperature provides a good breeding environment for mosquitoes.

　　Ruan Wenyong said that abnormal climate is a major cause of the rapid spread of dengue fever. According to the past rules, there will be a peak of dengue fever transmission in Vietnam every four to five years. However, in recent years, Vietnam’s climate has become hotter and wetter, with abundant rain, which has led to mosquito infestation. In the past five years, the number of confirmed cases of dengue fever in Vietnam has been at a high level every year.

　　Dengue fever is an acute infectious disease caused by dengue virus, which is mainly transmitted by mosquitoes and is prevalent in tropical and subtropical regions. Typical symptoms include persistent fever, headache, muscle pain, joint pain, etc., which can cause death in severe cases.

　　In order to curb the dengue fever epidemic, the Vietnamese Ministry of Health advised people to clean up the garbage in the house in time, try to wear long clothes and trousers to prevent mosquito bites, and cooperate with the local health department to take disinfection measures. When you have fever and other related symptoms, you should go to a medical institution for treatment in time, and you should not treat them at home.
