CNN —Genetically engineered mosquitoes have been released in the tiny East African country of Djibouti to combat a surge in malaria infections caused by an invasive vector. Unlike most malaria-transmitting mosquitoes in Africa that breed in rural areas, Anopheles Stephensi thrives in urban environments, intensifying the public health challenge for predominantly urban Djibouti. “This mosquito poses a huge threat to our fight against malaria,” said Grey Frandsen, CEO of US-owned biotechnology firm Oxitec, which developed the gene-modified mosquitoes released in Djibouti. ‘Using mosquitoes to fight mosquitoes’Dubbed a method that “uses mosquitoes to fight mosquitoes”, Oxitec’s genetic technology targets female mosquitoes, which are predominantly responsible for malaria transmission. Although the rollout of genetically modified mosquitoes in Djibouti is only the second in Africa, the idea is drawing more interest on the continent.

Some mosquitoes are actually helpfulThe first problem to tackle here is the word “all.” There are more than 3,000 recognized mosquito species worldwide. Healy, who is also president of the American Mosquito Control Association, offered Louisiana, which is home to many swamps where mosquitoes thrive, as an example. “Disease-transmitting mosquito species, such as Aedes aegypti and Aedes albopictus, are invasive species in many parts of the world. As for the Anopheles mosquitoes, which transmit malaria, things are a little different. … We are constantly educating mosquito control workers to follow these practices.

“The risk is very low,” Dr. Peter McElroy, chief of the malaria branch in the US Centers for Disease Control and Prevention’s Division of Parasitic Diseases and Malaria, told CNN. In an effort to limit its impact in the southeastern US during World War II, particularly around military training bases, the US created the Office of Malaria Control in War Areas in 1942. The April 1945 edition of the Malaria Control in War Areas field bulletin. Malaria was eliminated in the United States in 1951, but modern mosquito control is mostly managed locally. Oxitec also says it’s working on applying the approach to anopheles mosquitoes for malaria control as well.

The release of genetically modified mosquitos in Florida and Texas could not have caused recent cases of malaria detected in the U.S., as suggested in social media posts. The OX5034 mosquitos developed by Oxitec were approved by the U.S. Environmental Protection Agency in 2020 for pilot testing (here). Markowski noted that only female mosquitos “blood feed,” which needs to happen to transmit diseases like malaria, and the only genetically modified mosquitos being released are males, which feed only on plant juices and therefore cannot transmit malaria (explained further here). Reuters has previously addressed misinformation about uses of genetically modified mosquitos (here), (here) and (here). Recent cases of malaria in the U.S. could not have been caused by the release of genetically modified mosquitos.

(This story was corrected on July 27, 2023, to clarify that genetically modified mosquitoes were not released in Texas. The modified mosquitoes, which were released only in Florida, were all male, and only female mosquitoes feed on blood, which is how they transmit the malaria parasite from person to person, a mosquito-control expert said. Moreover, Markowski noted, only female mosquitoes “blood feed,” which needs to happen to transmit diseases like malaria, and the only genetically modified mosquitoes released are males, which feed only on plant juices and therefore cannot transmit malaria (explained further here).

Joe Raedle | Getty ImagesU.S. public health officials say the risk of locally transmitted malaria in the country remains low as seven new cases in Florida and Texas raise questions. "Despite these cases, the risk of locally acquired malaria remains extremely low in the United States," the agency added. The seven are the first known cases of "locally acquired" malaria in the country since 2003. Health experts say the new locally acquired cases shouldn't warrant panic about widespread malaria transmission in the U.S. Here's what you need to know about the locally acquired malaria cases in the U.S. – and why the risk of transmission remains low right now.

James Gathany/CDC/Handout/ReutersWhile serious mosquito-borne diseases remain rare in the US, other countries are not so lucky. While scientists are yet to assess the role climate change has played in the outbreak, Carlson said the links seem clear. But the shift of mosquito-borne diseases into regions like the US and Europe is still likely to be a shock. Scientists are working to develop tools to be able to better assess the link between mosquito-borne diseases and climate change. The path the world takes on reducing planet-heating pollution will lead to very different futures for mosquito-borne diseases, Brady said.

Three cases of malaria spread locally have been identified in Texas and Florida. But in Texas, the Department of State Health Services confirmed Friday that a person working outdoors in Cameron County, Texas, contracted malaria locally. According to the DSHS, although Texas sees about 120 malaria cases a year from international travelers, the last locally acquired case in Texas was detected in 1994. About 1,400 miles away in Sarasota County, Florida, however, two more cases of locally transmitted malaria infections have been identified this year — one in May and one in June. "And I think we should be funding more public health responses."

CNN —Anyone who has spent a summer evening swatting away mosquitoes, or a summer day scratching mosquito bites, can agree: Mosquitoes stink. In a scientific report published Friday, scientists helped pinpoint the different chemicals in body odor that attract these insects by building an ice-rink size testing arena and pumping in the scents of different people. Hundreds of mosquitoes in the main 20-by-20-meter facility were then treated to a buffet of the sleeping subjects’ scents. The researchers found what many who have been on a picnic would attest to: Some people attract more mosquitoes than others. (Vosshall said that even scrubbing with unscented soap doesn’t get rid of the natural scents that attract mosquitoes.)

A video circulating online shows a small sap-sucking insect called an aphid, not a genetically modified mosquito with a number stamped on it released by philanthropist Bill Gates, as online posts claim. Bill Gates was very vocal about releasing millions of GMO [genetically modified organism] mosquitos into the public.”Another example can be seen (here). However, the video shows a small insect called an aphid, not a GMO mosquito. A representative for the Gates Foundation said the claim that the video showed a genetically modified mosquito with a number or barcode stamped on it released by the Gates Foundation was false. The video shows an aphid, not a mosquito with a number stamped on it and released by Bill Gates.

Climate change may be driving the rapid spread of Candida auris, a deadly fungus, across the US. Three charts show how extreme weather and environmental changes help spread disease. Nicolas Armer/picture alliance via Getty ImagesA leading theory on this fungus's sudden emergence and wide spread is that it's fueled by climate change. Whatever survives, however, is adapted to extreme heat — including the fever our bodies produce to kill off pathogens.

A new study shows extreme weather, ocean changes, and land disruption have already helped spread more than 200 pathogens. That's an extreme case of climate change creating new contact between humans and infectious diseases, but the phenomenon is widespread. Extreme heat waves, for example, can kill off many infectious viruses, bacteria, fungi, and the creatures that spread them.

И специалисты задумались: сможет ли "искусственное солнце" снизить количество ночных укусов комаров? Команда учёных под руководством профессора Джайлза Даффилда (Giles Duffield) изучила комаров Anopheles gambiae, являющиеся основным переносчиком малярии в Африке. Специалисты провели эксперимент, изучая в лабораторных условиях поведение комаров. В течение 12 часов ночи исследователи с интервалом в два часа проверяли склонность комаров кусать руки волонтёров. Специалисты также провели и другой эксперимент, во время которого в помещении с комарами свет включался каждые два часа.

Sursa foto: nih.govRepublica Moldova, printre țările cu risc sporit pentru invazia malarieiVremea călduroasă și umedă favorizează o activitate mai mare a țânțarilor, iar odată cu aceasta sporesc și îngrijorările legate de malarie, o boală parazitară periculoasă pentru viață, transmisă prin înțepătura acestor insecte. În data de 24 aprilie, comunitatea internațională marchează Ziua Mondială a Malariei, iar cu acest prilej, Agenția Națională pentru Sănătate Publică atenționează că așezarea geografică şi condițiile climaterice situează Republica Moldova printre țările cu un risc sporit pentru invazia malariei. Din anul 2000, eforturile globale de combatere a malariei au dus la evitarea a milioane de îmbolnăviri și decese – dovada că progresul este posibil. Numărul estimat de decese cauzate de malarie a fost de 409 mii în 2019, comparativ cu 411 mii la nivel mondial în 2018. Ziua Mondială a Malariei a fost stabilită de statele membre ale OMS în cadrul Adunării Mondiale a Sănătății din anul 2007.
