Published: Feb. 1, 2025

Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic disease within the genus Phlebovirus. Symptoms of in animals range from moderate to severe febrile illness, which significantly impacts livestock industry and causes health complications humans. Similar bunyaviruses Orthobunyavirus transmitted by mosquitoes, RVFV progression dependent on susceptibility physical, cellular, microbial, immune response barriers vectors. These barriers, shaped genetic makeup mosquito species surrounding environmental temperature, exert strong selective pressure virus, affecting its replication, evolution, spread. The changing climate coupled with aforementioned bottlenecks are significant drivers RVF epidemics expansion into previously nonendemic areas. Despite link between microclimatic changes outbreaks, there still dearth knowledge how these temperature effects impact transmission vector competence persistence during interepidemic years. This intricate interdependence larval habitat temperatures, necessitates increased efforts addressing burden. review highlights recent advancements made shifting demographics, weather patterns, conveyance RVFV. Additionally, ongoing studies related temperature-sensitive variations RVFV-vector interactions gaps discussed.

Mosquito‐Borne Diseases in Canada: Integrated Perspectives on Disease Management and Influences of Environmental and Anthropogenic Factors Affecting the Transmission Cycle

Public Health Challenges, Journal Year: 2025, Volume and Issue: 4(2)

Published: April 21, 2025

ABSTRACT Globally, mosquito‐borne diseases (MBD) cause the highest morbidity and mortality in humans animals. Currently, Canada, endemic MBDs that are significant public health problems all zoonoses caused primarily by West Nile virus, Eastern equine encephalitis Californian serogroup viruses, including Jamestown Canyon Snowshoe hare viruses. The transmission cycles of these viruses changing, linked to global population movements (including vectors) climate land use changes. Here, we present state knowledge, related as well salient surveillance approaches carried out monitor them their infection rates. We propose a few theoretical operational research avenues order improve our understanding cycle changes, potential new tools such citizen science, metagenomics, artificial intelligence, remote sensing help reduce disease burdens on Canadians. This will support animal responses proactively manage under changing environmental conditions.

Mosquitoes from Europe Are Able to Transmit Snowshoe Hare Virus

Viruses, Journal Year: 2024, Volume and Issue: 16(2), P. 222 - 222

Published: Jan. 31, 2024

Snowshoe hare virus (SSHV) is a zoonotic arthropod-borne (arbovirus) circulating in colder areas of the Northern Hemisphere. SSHV maintained an enzootic cycle between small mammals and mosquitoes, assumably genera Aedes Culiseta. Symptoms human infection can range from asymptomatic to severe neuroinvasive disease. Studies on transmission are limited, there no information available whether mosquitoes genus Culex able transmit SSHV. Therefore, we investigated six mosquito species via salivation assay for their vector competence. We demonstrated that be transmitted by abundant European Cx. pipiens biotype pipiens, molestus, torrentium with low efficiency 3.33% 6.67%. Additionally, invasive Ae. albopictus also 3.33%. Our results suggest local after introduction Europe seems possible perspective.

Climate Change and Human Health in the Arctic: A Review

Climate, Journal Year: 2024, Volume and Issue: 12(7), P. 89 - 89

Published: June 22, 2024

Over recent decades, the Arctic has begun facing a range of climate-related challenges, from rising temperatures to melting ice caps and permafrost thaw, with significant implications for ecosystems human well-being. Addressing health impacts these issues requires comprehensive approach, integrating scientific research, community engagement, policy interventions. This study conducts literature review assess effects climate change on in northern latitudes compile adaptation strategies countries. A search was performed between January April 2024 papers published after 2000, using electronic databases Web Science, Pubmed, Science Direct, Scopus, Google Scholar, eLibrary.RU, specific questions formulated direct search: (i) What are changes? (ii) How does affect health? (iii) measures policies required? The key phrases “climate change”, “human health”, “adaptation practices”, “Arctic” were employed searching. Ultimately, 56 relevant studies identified, reviewing risks such as infectious diseases, mental issues, diseases connected extreme weather events; wildfires their associated pollution; degradation; pure water; food quality. paper also examines mitigation at all levels governance, emphasizing need international cooperation action combat negative outcomes, investments healthcare infrastructure, emergency preparedness, public education. Incorporating diverse perspectives, including Indigenous knowledge, Community-Based Adaptation, EcoHealth One Health approaches, is crucial effectively addressing change.

Snowshoe hare virus: discovery, distribution, vector and host associations, and medical significance

Journal of Medical Entomology, Journal Year: 2023, Volume and Issue: 60(6), P. 1252 - 1261

Published: Oct. 20, 2023

Abstract Snowshoe hare virus (SSHV), within the California serogroup of genus Orthobunyavirus, family Peribunyaviridae, was first isolated from a snowshoe (Lepus americanus) in Montana, United States, 1959. The virus, closely related to LaCrosse (LACV) and Chatanga (CHATV), occurs across Canada northern latitudes primarily tier states bordering Canada. Reports SSHV Europe Asia are probably CHATV, or less Tahyna virus. Vertebrate associations include hares ground squirrels, demonstrated by field isolation wild-caught animals, seroconversion hares, sentinel rabbits, experimental infections demonstrating viremia. Isolations populations mosquitoes univoltine boreal Aedes, Culiseta impatiens inornata; and, rarely, certain multivoltine floodwater Aedes species. Experimental transmission studies show infection inornata. Isolation larval on three occasions, experimentation inornata, reveal transovarial mosquitoes.

Over the past couple of decades, mosquito-borne diseases have increased in Canada. ‘Planetary Health’ is a novel concept that encompasses impacts triple planetary health crisis climate change, nature and biodiversity loss, pollution waste. This study aimed to conduct rapid scoping review on with regard mosquitoes Canada, order understand complex relations. synthesis will identify knowledge gaps, emerging threats, mitigation scopes it inform future research scopes. An online query EMBASE, PubMed, Web Science was performed total 2,086 citations were retrieved. Finally, 62 articles then reviewed synthesized. Temperature precipitation are playing significant roles mosquito abundance, extension temporal distribution spread from historical distributions invasive species newer geographic locations. In fact, temperature has been rising so high some now predominantly producing eggs without having taken blood meal (autogeny). Warmer temperatures vector viral loads by several folds, thereby, change effectively making infection rates higher extending transmission season. Destruction natural environment due anthropogenic activities depopulates native predators resulting flourishing populations. Pesticides used control often failed gain desired results operational technological limitations unintended ecological consequences. Planetary Health perspective can provide comprehensive analysis mosquitoes’ presence establishment expansion disease carrying capacity for both species. Thus, Canada at risk outbreak exotic infections. For public measures research, perspectives required better multifaceted connections between infections, ecosystem, activities.
