Saúde · Mosca-da-bicheira do Novo MundoO Arizona se preparou para a mosca-da-bicheira. Um caso confirmado em um cão põe essa preparação à prova.Escrito 29 de outubro de 2026 às 05:07 UTCAssistirTranscrição0:07A tissue-eating parasite has infected a dog in Cochus County.0:10State and federal agencies are increasing animal monitoring and establishing an0:13infested zone.0:14New world screwworm can leave pets, livestock, and wildlife with wounds that deepen0:18and turn deadly.0:19Animal owners are waiting to learn where that zone will extend and what rules will0:23apply.0:23The confirmed dog was found in Cochus County, Arizona.0:26The Federal Animal and Plant Health Inspection Service is coordinating the response0:30with the Arizona Department of Agriculture.0:32Nearby Douglas already features in the state's preparedness plans.0:36One dog is identified in the federal announcement issued October twenty-eight.0:39Testing at the agency's National Veterinary Services Laboratories confirmed the0:43parasite.0:43That count describes the animal announced and leaves the wider extent of infection0:47unresolved.0:48State officials describe this as Arizona's first confirmed case since one thousand0:52nine hundred and sixty six federal animal health officials call it Arizona's first0:57detection.0:57The one thousand nine hundred and sixty-six milestone refers to U.S.1:01eradication.1:02Arizona's last earlier case date is unclear, so a precise sixty-year absence in the1:07state remains uncertain.1:08Screwworm larvae eat living tissue.1:10Adult flies lay eggs at wounds or moist body openings.1:13As the larvae feed, wounds can grow larger and deeper.1:16The damage can be serious and sometimes deadly.1:19The adult fly is about the size of a common house fly or slightly larger.1:22Its scientific name is cochleomia hominivorax.1:25The infestation is called myisis, meaning an infestation by fly larvae.1:30Dogs, other pets, livestock, and wildlife can all be affected.1:34Maggots in a draining or enlarging wound are a warning sign.1:37Check body openings, including the nose, ears, navel, and genitals.1:40Recent injuries and surgical wounds warrant attention.1:43Painful, rapidly deepening wounds can also develop a bacterial infection.1:47Identifying the larvae matters because maggots in a wound alone don't identify the1:51species.1:52Suspected animal cases should be reported to the state animal health official or a1:55USDA veterinarian.1:56Humans can also be infested, though less commonly than animals.2:00Even a small skin break can provide an entry site.2:03Infestation can also involve the eyes, ears, nose, mouth, genital, or anal areas.2:08A rapidly worsening foul-smelling wound with significant pain is a human warning2:13sign.2:13Larvae may be seen or felt.2:15The Arizona detection involves a dog.2:17The biological route involves flies laying eggs.2:20A confirmed human infection hasn't been announced here.2:22For animal owners, containment could affect transport.2:25October National Guidance calls for specified domestic animals leaving an infested2:29zone to be inspected and found free of screwworm or treated until free.2:32The actual Arizona boundary and applicable movement requirements still need to be2:36announced.2:37USDA had committed up to twenty-five million dollars for a sterile fly dispersal2:41facility in Douglas.2:42That preparedness investment was described on August thirteenth.2:45Before this detection, sterile insect technique is an established approach to2:49eradicating screwworm.2:50The investment describes planned capacity.2:53It doesn't tell animal owners whether that facility is operating or whether flies2:56have been released for this case.2:57Phased reopening at Douglas began August '24 .3:00Arizona's existing Southern port measures included heightened screening, tracking,3:04and inspection of cattle from Sonora.3:05Those preparations were already in place before the dog announcement on October3:09twenty-eight.3:09An elk on a game ranch in Pecos County, Texas, had also tested positive by October3:14twenty-four.3:15That separate detection was identified as the current outbreak's first U.S.3:19wildlife case, and it prompted expanded surveillance.3:21Arizona's confirmed response is increased monitoring and work to establish a3:25containment area.3:26Officials still need to explain the dog's exposure history and outcome, and release3:30results from other animals.3:31Those findings will help show whether the infection was acquired locally and how far3:35the response needs to reach.Ler o artigoCronologia da históriaHeyDexQuem noticiou o quêPontos noticiados por mais de um veículo✓Dog tests positive for New World screwwormConfirmado de forma independente · 2 veículos✓Infested zone established in Cochise CountyConfirmado de forma independente · 2 veículos✓First confirmed Arizona case since 1966Confirmado de forma independente · 2 veículos✓Agencies increase animal monitoringConfirmado de forma independente · 2 veículosCada linha é a afirmação como a registramos da reportagem daquele veículo.
