Health officials in Antigua and Barbuda confirmed the death of a visiting traveler who contracted malaria after arriving from a malaria-endemic country; the death is considered imported with no evidence of local transmission. Authorities also reported a second imported malaria case in recent days and said public health teams have intensified surveillance and mosquito-control efforts to prevent any spread.
Los Angeles County’s vector-control district is expanding the sterile insect technique to curb Aedes aegypti mosquitoes linked to dengue, releasing sterilized males and seeking to broaden the program beyond Sunland-Tujunga. The expansion hinges on a new funding mechanism—a up to $20 per year per single-family home via a property benefit assessment on top of the existing $18.97—despite only 47% of ballots supporting the increase and opposition from some business owners. Pilot releases in two Sunland-Tujunga neighborhoods cut the female mosquito population by about 82%, but officials say broader adoption requires more funds and public buy-in; a second ballot round is planned while production continues in the insectary and field releases.
Health officials in Australia have detected the first case of Japanese encephalitis virus for the summer, raising concerns due to increased mosquito populations driven by climate change. The virus, which can cause severe brain inflammation and is spread by mosquitoes, prompts precautions like using bug spray and removing stagnant water. Researchers are exploring new control methods, but reducing pollution remains key to managing mosquito-borne diseases.
Scientists have engineered a floral-scented fungus that attracts and kills mosquitoes, offering a safe, affordable, and environmentally friendly alternative to chemical pesticides, with potential to reduce mosquito-borne diseases globally.
Officials in Canyon County, Idaho, detected the first known Aedes aegypti mosquito, a species that can spread diseases like dengue and Zika, prompting increased monitoring and public awareness efforts to prevent its spread and protect local ecosystems and health.
The article discusses how the bacterium Wolbachia, naturally found in many insects, can be used to reduce the spread of dengue fever and other tropical diseases by making mosquitoes less capable of transmitting viruses. Trials in Indonesia, Australia, Brazil, and Colombia show significant reductions in disease incidence, and the method is self-sustaining and non-GMO. Challenges for scaling include public acceptance, funding, and logistical issues, but the potential to protect millions makes it a promising solution.
Naperville has tested positive for West Nile virus in mosquito traps and is urging residents to take precautions such as removing standing water, using repellents, and wearing protective clothing to prevent mosquito bites and reduce the risk of infection, especially around upcoming events like the Last Fling festival.
Brevard County, Florida, is using mosquitofish as a natural and chemical-free method to control mosquito larvae, aiming to reduce the need for spraying and other treatments, especially amid rising mosquito-borne illness cases like dengue fever.
A resident in Vintondale, Cambria County, has been hospitalized after contracting West Nile virus, prompting local officials to deploy mosquito traps and advise residents to take precautions against bites.
The Moorhead City Council delayed its planned aerial mosquito spraying after residents expressed concerns about pollinator safety and environmental impact, opting instead for ground spraying while reviewing its mosquito control policies amid ongoing debates about health risks and ecological effects.
China has launched an extensive campaign to combat a Chikungunya virus outbreak in Guangdong, employing drones, biological controls, and mass fumigation, reminiscent of Covid-19 measures, to eradicate mosquitoes and prevent further spread of the disease.
China is experiencing its largest chikungunya virus outbreak with over 7,700 cases, mainly in Foshan, prompting aggressive containment efforts including insecticide spraying, public health enforcement, and community engagement, amid concerns about the virus establishing itself locally for the first time.
A dozen mosquitoes in Greene County tested positive for West Nile Virus, prompting public health measures including spraying and advice on mosquito prevention to protect residents from the virus, which is transmitted through mosquito bites and can cause serious neurological issues.
China is actively combating its first outbreak of chikungunya virus using measures such as drone surveillance to find standing water, insecticide spraying, fines for water receptacle neglect, and strict quarantine protocols, amid heavy rains and high temperatures that facilitate mosquito breeding.
China is actively responding to a chikungunya virus outbreak with measures such as mosquito control, disinfectant spraying, fines for standing water, and drone surveillance, amid over 7,000 cases mainly in Foshan, with efforts to contain the spread and prevent further infections.
