According to the CDC WeChat official account, dengue fever is a common infectious disease in China. With the warming weather and increasing rainfall, China will gradually enter the high incidence season of dengue fever. It is necessary to do a good job of mosquito prevention at home and stay away from dengue fever. Dengue fever occurs at any time? No, the incidence of dengue fever is seasonal, and the high incidence period is the active period of vector Aedes mosquitoes (with temperatures stable above 25 ℃). The peak season for dengue fever in most parts of China is summer and autumn (August September), with warmer climates in parts of Hainan, Guangdong, Guangxi, and Yunnan. The peak season is from May to November. Which regions in our country have dengue fever? Because dengue fever is only transmitted through the bite of the vector Aedes mosquitoes (commonly known as "spotted mosquitoes"), it is only possible to develop dengue fever within the distribution range of "spotted mosquitoes" in China, and meteorological conditions are suitable, allowing mosquitoes to maintain a high density. Except for Xinjiang, Qinghai, Inner Mongolia, Heilongjiang, and Jilin, other provinces in China have the distribution of spotted mosquitoes, which have the conditions to transmit dengue fever. However, in the past, dengue fever mainly affected southern provinces such as Yunnan and Guangdong in China. Under what circumstances should one suspect having dengue fever? If you have been staying in areas where dengue fever is prevalent in Southeast Asia, South Asia, Latin America, or have already experienced dengue fever in your community, street, or even city where you live or work within the past two weeks before the onset of the disease, then when symptoms such as fever, rash, headache, and myalgia occur, you need to consider the possibility of contracting dengue fever. At this time, it is important to seek medical attention at a reputable hospital as soon as possible and proactively explain your travel history to the doctor in order to receive prompt diagnosis and treatment. What are the differences between the symptoms of dengue fever and influenza? Dengue fever and influenza have similar symptoms, including fever, fatigue and pain, which are easily confused. But influenza usually occurs after contact with patients, mostly in winter and spring, and is often accompanied by respiratory infections such as sore throat, runny nose, cough, and sneezing. Dengue fever patients have a history of mosquito bites before onset, which is more common in hot weather without respiratory symptoms. More than half of them may develop rashes, sometimes with skin redness and subcutaneous bleeding points. How to find and eliminate the spotted mosquito? To find the spotted mosquito, you need to understand their habitat. The Aedes albopictus mainly inhabits dark and sheltered areas outdoors, such as the inner walls of tanks, jars, and jars. The inner wall of the foundation trench with accumulated water on the construction site. You can focus on these areas outdoors and spray insecticides; Indoors tend to stay on walls, tables, chairs, and under beds, as well as hanging clothes. Aedes aegypti is a typical "home mosquito" that mainly inhabits windproof and dark indoor areas, such as at the foot of a water tank, behind a cupboard, under the bed of a bedroom, in the corners of a wall, and under mosquito nets. The black clothes hanging with sweat stains are more favored by them. Mosquito repellent or electric mosquito repellent liquid can be used to repel mosquitoes in the room, and screen doors and windows should be used for mosquito prevention. Understand the activity time of Aedes mosquitoes. The Aedes albopictus is particularly active in the morning and near dusk, as if it is "commuting" with us; Egyptian Aedes mosquitoes are particularly active in the morning and near dusk, and they actively suck blood throughout the day. Using insecticides during their active period naturally yields twice the result with half the effort. What other measures besides mosquito control can prevent dengue fever? Long
