Aedes aegypti mosquitoes, native to tropical regions and carriers of diseases like dengue and Zika, have been found thriving in Grand Junction, Colorado, due to warmer winters and climate change, raising concerns about potential disease outbreaks in the region.
Authorities in California are concerned about the spread of the invasive Aedes aegypti mosquito, which can transmit diseases like dengue and Zika, as it expands across multiple counties, driven by climate change and urbanization. Efforts include increased surveillance and community participation to control its spread, highlighting the need for environmental action to address broader ecological impacts.
Invasive Aedes aegypti mosquitoes, known for transmitting diseases like dengue and Zika, are spreading in Northern California, including the San Francisco Bay Area, raising public health concerns and urging residents to eliminate standing water to control their spread.
The Department of Health in the Philippines reported 8,460 dengue cases in the first two weeks of October, urging the public to eliminate mosquito breeding sites during the rainy season and seek medical attention if symptoms appear.
A genetic study reveals that the mosquito thought to have evolved in London's Underground actually has a much older origin in the Mediterranean, dating back 1,000 to 10,000 years, and migrated to London over time.
A mosquito capable of biting ankles has been found in Washington County, prompting a public health alert to inform residents about potential risks of mosquito-borne diseases.
Michigan officials are monitoring the invasive and aggressive Aedes albopictus mosquito, also known as the Asian tiger mosquito, which bites during the day and can carry viruses like West Nile, dengue, Zika, and chikungunya, though the current disease risk is low. Preventative measures include eliminating standing water and using repellents.
Health officials in the UK warn of a concerning rise in chikungunya virus cases, more than doubling from last year, primarily linked to travelers returning from abroad. The virus, transmitted by mosquitoes, can cause debilitating symptoms and is exacerbated by climate change and extreme weather, which expand mosquito habitats. Experts emphasize prevention measures and legislative efforts to combat vector-borne diseases.
The chikungunya virus has infected over 7,000 people in southern China, marking the largest outbreak in the country, with authorities deploying nets, insecticide, and drones to control the spread amid heavy rains and high temperatures.
Two aggressive, disease-causing Aedes aegypti mosquitoes were found in Livermore, California, marking the first detection in the area. Residents are urged to eliminate standing water and take protective measures to prevent the spread of diseases like dengue and Zika.
Scientists tested a natural mosquito repellent called Kreopik on 32,000 tiger mosquitoes, with the researcher remaining bite-free after over twenty minutes in a sealed enclosure, demonstrating its high effectiveness and potential as a safe alternative to chemical repellents in combating mosquito-borne diseases.
Massachusetts has confirmed its second case of Eastern Equine Encephalitis (EEE) in mosquitoes this year, with no human or animal cases reported yet. The infected mosquitoes were found in Bridgewater and Belchertown, prompting health officials to advise precautions such as using insect repellent and eliminating standing water to reduce mosquito bites. EEE is a deadly virus with a high fatality rate and potential for severe neurological damage, but most human cases occur in late summer and early fall.
The Cincinnati Health Department confirmed the first West Nile virus detection in the city in 2025, with a mosquito in Madisonville testing positive. Authorities advise residents to prevent infection by eliminating standing water and using repellents, especially during dawn and dusk. Last year, Cincinnati reported 24 positive mosquito pools but no human cases, with the last human infection in 2015.
Scientists have developed a genetically modified fungus that acts as a sexually transmitted disease for mosquitoes, effectively killing female mosquitoes that spread malaria, and could become a powerful tool in controlling the disease's spread.
The Hawaii Department of Health has confirmed a case of Zika virus on Oahu, the first since 2019, prompting warnings for residents and visitors to use insect repellent and eliminate standing water to prevent mosquito bites, especially due to the virus's danger to pregnant women and its potential to cause severe fetal conditions.
