It displays the beginning of summer Mosquito High SeasonHealth and vector control authorities prepare for one year of historical dengue. And due to climate change, there is a lack of effective vaccines and federal cuts, so we are concerned that the disease will be owned in a wider North American strip.
Last year 3,700 new infections According to the Centers for Disease Control and Prevention (CDC), by the dengue of the United States compared to 2,050 in 2023. All examples of 2024 were acquired from abroad, except for 105 contracts in California, Florida or Texas. In March, the CDC issued warning warnings about the continuous risk of dengue fever infection.
“I think dengue fever has stayed,” he said. Michael Ben-RadeInfectious diseases experts and hospital mechanics medical officers Cedars-sinai Los Angeles’ dengue fever is about the possibility of becoming a new top of the country. “This mosquito will not go anywhere.”
Dengue Many warm areas The same world as Latin America, India and Southeast Asia. Dengue They have increased significantly Many regions last year, especially in central and South America.
A disease that can spread AEDES Mosquito They carried their viruses and were not common on the continent of the United States for most of the last century. Currently, most dengue fever (ie, not related to travel) is registered in Puerto Rico. Powerful increase in 2024Regional public health emergencies triggered.
Most people who develop dengue fever They do not hurt. But in some cases, the symptoms are serious. Nose or mouth bleeding, intense abdominal pain, vomiting and edema. Sometimes dengue fever causes death.
California offers a Sentinel case on the spread of dengue fever in this country. 25 years ago, Unknown The presence of AEDES AEGYPTI and AEDES ALBOPICTUS mosquitoes delivers dengue fever from the main. Currently, I know It is not found in 25 counties and more than 400 cities and communities.Mainly in the southern California and the Central Valley.
Mosquitoes are worried that their presence increases the possibility of disease transmission. California Mosquitoes and Vector Control Association.
Between 2016 and 2022, California had an average of 136 new dengue fever every year, each of which had traveled to another place and brought to the state. In 2023, about 250 new cases were recorded, including two local acquisitions.
In 2024, California registered 725 new dengue fever cases. State data.
Ben-ADET said climate change could contribute to the population of Edes mosquitoes. This mosquito survives better in warm urban areas and usually chopped during the day. Local infections are generally evaluated by AEDES mosquitoes that are generally a mosquito who responds to dengue fever during a trip, returns home, and itchy and infect others.
Ben -Ade Ret said, “It quickly spread throughout California.
Dengue fever shows a challenge to many primary medical doctors who have never seen it. Ben-Adet said that a doctor suspected of dengue fever should get a detailed travel record for the patient, but the diagnosis is not always fast.
“There is no simple test to detect,” he said. “The only test for dengue fever is an antibody test.” “Most labs are probably not marketing, so it’s a test that should be analyzed in other installations. Therefore, it is essential for someone to suspect that there is a dengue.”
Abshier says that the best practices to avoid dengue fever include removing the stagnant water from the real estate and using mosquitoes, Abshier said. Limiting the activities of sunset and dawn can help if mosquitoes bite more often.
Efforts to fight dengue in California have become more complicated this year after forest fires swept angels.
The fire occurred in the area with a high incidence of diseases spread by mosquitoes. San Gabriel Valley Mosquito and Vector Controlt officials worked for several months to treat more than 1,400 maintenance pools left after the fire to remove mosquito farms.
These police officers deal with swimming pools using local and state resources, according to Anais Medina Díaz, a spokesman for the earth. They asked for repayment to the Federal Emergency Management Agency (FEMA), which historically did not fund the vector control initiative after the forest fire.
In California, vector control agencies generally raise funds with local fees paid by taxes and owners.
Some officials are implementing new methods. Release sterilized mosquitoes To reduce the problem. Abshier said that this can be effective, but it is expensive to implement methods in many regions and will require huge effort at the main level.
Meanwhile, the federal government is reducing intervention. Some media have the National Health Institute They will stop financing New studies related to climate change, dengue heat work may be included.
This year’s dengue fees have been reported in many parts of the United States. It has been significantly reduced since 2024. However, the US trend is likely to not be clear until the end of the summer season.
Vector health and control researchers are not sure of the seriousness of the California situation.
While some argue that the occurrence may be limited, some predict that dengue fever may worsen. Sujan shestaAnother places like Nepal, professors and researchers at Jolla’s immunological research institute, have recently experienced relatively dengue fever cases in the past, but now there is a large number of big outbreaks.
There is a children’s vaccine It is being stopped Due to the lack of world demand. There are no two other vaccines in the United States. Shrest Laboratory work hard Effective and safe vaccine In the dengue. Wait to publish the results of the animal within about a year. If they are positive, human rehearsal can be possible within about two years.
“Without a good vaccine or a good antivirus, it will be a dengue climate disease,” he said.
