Dengue fever epidemic! 641 cases of eucalyptus and new dry diagnosis! The day before, the Jiangxi Provincial Health and Health Committee informed: Recently, the dengue fever epidemic occurred in Yushu City and Xingan County.
As of 12:00 on September 5, 641 cases of dengue fever were reported in the two places, and 392 cases were discharged. Among them, 598 cases of dengue fever diagnosis in Yushu City, 390 cases of recovery from hospitalization; 43 cases of dengue fever diagnosis in Xingan County, 2 cases were discharged from hospital. There were no serious cases or deaths in both places.
According to epidemiological investigations, the epidemic was triggered by the importation of dengue virus from tourism returnees in Southeast Asia. After the outbreak, the two places promptly launched an emergency response mechanism to do patient treatment, carry out patriotic health campaigns, and strengthen prevention and control measures such as mosquito and mosquito killing.
The Provincial Health and Health Commission sent disease prevention and control and clinical medical experts to the local authorities to guide the prevention and treatment of the epidemic. At present, the prevention and control of dengue fever in both places has been carried out in an orderly manner, and the epidemic situation can be prevented and controlled.
What is dengue fever?
Dengue fever is an acute infectious disease caused by dengue virus, but it cannot be transmitted directly from person to person, but is transmitted by mosquitoes. The medium is Aedes aegypti and Aedes albopictus (Aedes albopictus is commonly known as "flower mosquito" ", is a common mosquito species in Guangdong).
After the Aedes mosquito bites a dengue fever patient or a latent infection, the virus can be replicated in the mosquito. When the Aedes mosquito bites another healthy person, the virus can be passed on to others.
Dengue fever is widely prevalent in tropical and subtropical countries and regions, such as Southeast Asia and the Pacific Islands, and is highly prevalent every July-September.
The incubation period of dengue fever
The incubation period for dengue (ie, from exposure to the virus to the onset of clinical symptoms) is 3-15 days, but usually 5-8 days.
In other words, if there is no fever or other symptoms for more than 2 weeks after returning from a popular area, it is unlikely to be infected with the dengue virus.
Symptoms of dengue fever
In general, nearly 80% of dengue-infected people have no obvious symptoms, or only mild symptoms (such as simple fever), and less than 5% of patients will have severe symptoms.
After being bitten by a mosquito carrying a dengue virus, the patient's symptoms are very similar to the flu. There are generally the following symptoms:
● Fever to above 40 ° C
● pain behind the eyes
● nausea and vomiting
● Gland swelling
● joint, bone or muscle pain
The risk of dengue fever in children is high. In addition, pregnant women, the elderly, and obese people are also susceptible to dengue fever. Once these people start to have mild symptoms, it is recommended to see a doctor immediately.
It should be noted that after 3 to 7 days of onset, some patients' body temperature has dropped, but in fact it may be aggravated. Therefore, pay attention to the following alarm signals as soon as possible:
● severe abdominal pain
● persistent vomiting
● bleeding gums
● shortness of breath
● fatigue, restlessness
Once this happens, you should be taken to hospital for treatment.
Prevention of dengue fever
Dengue fever is mainly transmitted through the bite of Aedes albopictus (Piecea gracilis), which mainly breeds eggs in clean small water. Therefore, prevention and control from the source, removal of mosquito breeding grounds (home and external environmental water) is dengue fever. Key measures for prevention and control.
The prevention of dengue is to prevent mosquito bites + killing mosquitoes.
Spray insect repellent
Spray the insect repellent on exposed parts such as the head, arms, and legs. Generally, it needs to be sprayed once every 2 to 4 hours. The qualified mosquito repellent products produced in China can be safely used for infants and young children over 2 months.
Anti-mosquito in the home
Install the screen door screen: it can effectively prevent mosquitoes from entering, and can also spray insecticide on the screen window to enhance the protective effect;
Clear water everywhere: pots, floor drains, air conditioners, trash cans, which are prone to water accumulation, should be cleaned up to prevent mosquito breeding;
Use mosquito nets when sleeping, or use mosquito repellent products: It is recommended to use mosquito repellent products containing DEET, Mosquito Repellent, Eccaridine, Lemon Leaf Leaf Oil;
Use insecticidal aerosol: Be careful not to spray directly on the sheets and clothing, collect the tableware before spraying, close the doors and windows after spraying, wait for 1 hour, open the window and ventilate, then enter the room after dissipating.
Pay attention to your recent trip!
Next week is about to enter the Mid-Autumn Festival holiday, and those who are going out to travel and travel in areas with dengue fever should do their personal protection:
● Wear light-colored long-sleeved tops and trousers, and apply exposed insect repellent to bare skin;
● Wear clothes, trousers and socks soaked with pyrethroid insecticide when conditions permit, which can be more effectively protected;
● Rent a hotel with good sanitation and few mosquitoes;
● Try to avoid staying in outdoor shades such as gazebos and green belts, and keep away from water, waste tires and other places that are prone to mosquitoes.
Usually 8 to 10 am and 4 to 6 in the evening are the peak hours of Aedes mosquitoes. Try not to go out during these time periods.
However, there is no need to panic after infection with dengue fever. Dengue fever is a self-limiting disease. Most people are infected after the infection. After rest and symptomatic treatment, it usually improves in 7-10 days. A small number of people, such as the elderly, pregnant women, infants and children with chronic diseases, may develop severely, endangering the digestive tract, intracranial hemorrhage, and serious death.
Reminder: If you have symptoms such as fever, rash, soreness, etc., you should go to the hospital for examination in time. If you are suspected or diagnosed, you must immediately prevent mosquitoes from being isolated. Remind each other! Pay attention to prevention!
