Timely report the problems existing in the current dengue prevention and control work to the local government, strive for the support of the local government, and carry out various dengue prevention and control work with the participation of multiple departments and the increase of special funds. In strict accordance with the relevant requirements, local disease prevention and control institutions have implemented various tasks to improve the monitoring level and prevention and control ability of dengue fever in our province.

With the support of relevant government departments, we actively carry out various forms of dengue prevention and control knowledge publicity. Widely mobilize the masses to implement prevention and control measures such as cleaning water tanks, turning over pots, cleaning small water containers, and eliminating breeding grounds of Aedes aegypti larvae. All medical institutions should strengthen the diagnosis of emergency and outpatient fever patients, strengthen the training of dengue fever knowledge for clinicians, and do a good job in the registration of fever outpatients.

When the first case of dengue fever is found, it should be reported step by step in the fastest way, and at the same time, people should be sent to conduct epidemiological investigation immediately to verify the diagnosis, isolate the patient in time, and spray the room with a radius of 50- 100 meters around the patient's house with quick-acting pesticides to kill adult mosquitoes. People are required to thoroughly clean the water tank to change water, clean up all idle small water containers, and take good care of small water containers for daily use to ensure that mosquito larvae do not breed. Taking the above measures for 2-3 times in a row can kill all mosquito vectors with virus and reduce the density of mosquito larvae. The Brett index can be controlled below 5, and no new cases are found in the longest incubation period (15 days) before normal surveillance. Cities and counties should reserve a certain number of mosquito killers, sprayers and protective articles according to the actual situation.

Aedes aegypti-Transgenic Aedes aegypti controls the spread of dengue virus.

20 12 12 in February, mosquito control experts in the south Florida islands of the United States are waiting for the approval of the federal government. They are going to release hundreds of thousands of genetically modified "biochemical mosquitoes" to stop the spread of dengue fever in this area.

These mosquitoes carrying "self-destructive genes" will be released to the Florida keys to mate with wild mosquitoes carrying deadly diseases such as dengue fever, transmit fatal birth defects and be completely eradicated before the offspring of those mosquitoes are born. The experiment was jointly planned by local officials in charge of mosquito control in the Keys and a British company, targeting Aedes aegypti, a vector mosquito carrying dengue fever and other viruses. Scientists say that all they plan to release are male mosquitoes that don't bite. These hundreds of thousands of male mosquitoes have been genetically modified, hoping that they will mate with female mosquitoes in the wild and pass on their birth defects to their offspring. Within a few generations, Aedes aegypti, which carries threatening diseases, is expected to be eradicated without causing a huge chain reaction in the natural ecosystem.
