Dengue Fever Prevention Measures

Dengue fever is very harmful, especially to children. Southeast Asia is a region with a relatively high incidence of this disease. To prevent dengue fever, the most important thing is to eliminate the Aedes albopictus. We know that mosquitoes often like places with water. Puddles, dirty water, and some vases and water in construction site containers outside should be removed in time to avoid mosquito breeding.

Dengue Fever Prevention Measures

1. Eliminate breeding grounds and larvae: turn over pots and cans, fill tree holes, wash drinking water containers frequently, change water frequently, and cover them to prevent mosquitoes. You can also use fish that eat mosquito larvae or other biological methods to eliminate mosquito larvae in water tanks. For water accumulated in non-drinking containers that is difficult to completely clear, waste oil or slow-release pesticides can be sprayed. 2. Kill adult mosquitoes: Spray or apply insecticides that are non-toxic to humans to eliminate adult mosquitoes indoors. Outdoors, on the basis of maintaining good environmental hygiene, insecticides should be used mainly in places with more adult mosquitoes, such as bamboo forests, pottery sites, and waste tire storage stations.

Symptomatic treatment

1. Physical cooling should be the main approach for high fever. Alcohol baths should be avoided for patients with obvious bleeding symptoms. Antipyretic analgesics are not ideal for reducing fever in this disease and may induce hemolysis in patients with G-6PD deficiency, so they should be used with caution. For patients with severe poisoning symptoms, small doses of adrenal corticosteroids can be used for a short period of time, such as oral prednisone 5 mg 3 times a day. 2. Maintain water and electrolyte balance. Patients with profuse sweating or diarrhea should be encouraged to take oral rehydration. Patients with frequent vomiting, inability to eat, or dehydration and insufficient blood volume should receive intravenous infusion in a timely manner. However, one should be highly vigilant against infusion reactions that may worsen the condition and lead to cases of meningoencephalitis. 3. Those with bleeding tendency can choose hemostatic drugs such as Anluoxue, Zhixuemin, vitamin C and K. For cases of massive bleeding, fresh whole blood or platelets should be transfused, large doses of vitamin K1 should be given intravenously, Yunnan Baiyao should be taken orally, and patients with severe upper gastrointestinal bleeding can take cimetidine orally. 4. In cases of shock, rapid infusion should be given to expand blood volume, and plasma and plasma substitutes should be added. Patients with DIC should not receive whole blood transfusion to avoid blood concentration. 5. For cerebral type cases, 20% mannitol 250-500 ml should be used promptly and injected intravenously rapidly, and dexamethasone should be dripped intravenously at the same time to reduce intracranial pressure and prevent brain herniation.
