"This year, the dengue fever epidemic in America and Southeast Asia is more serious than the same period of last year."
Wuhan disease control center
Director, Institute of Disinfection and Vector Control
Chen Xiaomin reminded a few days ago
During the "May Day" holiday
Outbound travel must take preventive measures.
01
Return from dengue endemic area
Report any abnormality in time.
"Dengue fever is an acute insect-borne infectious disease caused by dengue virus, which is mainly transmitted by the bite of Aedes mosquitoes." Chen Xiaomin introduced that the epidemic situation of dengue fever in China is dominated by imported cases. At present, Southeast Asia, South Asia and Latin America, such as Indonesia, Malaysia, Thailand, Singapore, Bangladesh, Cambodia, Laos, Brazil, Argentina, Colombia, Paraguay and other countries have entered the dengue epidemic season, and the epidemic situation is obviously more serious than the same period of last year.
People returning from countries and regions with dengue fever should declare to the customs voluntarily when they enter the country if they have symptoms such as fever, headache, muscle and joint pain, rash and flushing on their face, neck and chest.
02
Pay attention to mosquito prevention during outbound travel.
Dengue fever will not be "human-to-human", and the focus of infection prevention is mosquito prevention. The following mosquito prevention points should be paid attention to.
1. Wear long clothes and trousers outdoors, and use mosquito repellent containing deet, ecarridine and IR3535.
2. Choose hotels or homestays with complete protective facilities such as screens, screen doors and mosquito nets for accommodation. Close the screen doors and screens in the rooms, and pay special attention to mosquito nets for cribs and strollers.
3. Mosquito-repellent incense, aerosol and other insecticides can be used in the room to kill mosquitoes. Follow the product instructions to avoid children’s contact.
4. Avoid staying in outdoor shady places such as shade, grass and gazebo.
5. If you have suspected symptoms such as fever and rash, you should see a doctor in time and take the initiative to explain the situation of being bitten.
6. After returning to the local area, if you have fever within 2 weeks, you should see a doctor in time and explain your travel history, and cooperate with the local health department for hospitalization and isolation treatment.
03
There is "three pains and three redness"
Seek medical attention in time and inform the travel history.
Typical symptoms of dengue fever include "high fever rash, three pains and three redness", that is, sudden high fever above 40℃, severe headache, joint pain all over the body, muscle aches, blushing, red neck and red chest skin. In addition, the patient will have a congestive rash or punctate bleeding rash on the trunk or head and face of the limbs.
According to Chen Xiaomin, about 1/4 people infected with dengue virus will get sick, among which repeated infection, infants and pregnant women are more likely to cause severe illness. If the above symptoms appear within 2 weeks after returning from the tour, you should seek medical advice in time and take the initiative to inform the overseas travel history.
According to experts, there is no specific antiviral drug for dengue fever at present. Patients should have a full rest after onset, use screen doors, screens and mosquito nets to prevent mosquito isolation, and people living together should also pay attention to anti-mosquito measures to avoid mosquito bites.
The fever of dengue fever is mainly reduced by physical cooling, but patients still have the risk of getting worse after the fever is reduced. Once there are symptoms such as abdominal pain, persistent vomiting, red spots on the skin, mouth and nose bleeding, hematemesis and bloody stool, lethargy and irritability, cold skin and dyspnea, they should immediately return to the clinic or emergency department for observation and treatment.
