Emerging and re-emerging mosquito-borne viruses pose a significant threat to global public health. Unfortunately, effective preventive and therapeutic measures are scarce. An in-depth understanding of the mechanisms regulating viral pathogenesis, vector competence, and viral transmission between mammalian hosts and vectors may lay the foundations for new preventive and therapeutic approaches. Here, we summarize the intricate interactions between commensal microbes and mosquito-borne viruses in mammalian hosts and mosquitoes, including how the host gut microbiota influences the pathogenesis of viral infection; how the host skin microbiota affects the attractiveness of hosts to mosquitoes and viral transmission; and how symbiotic microbes, including endosymbiotic bacteria, fungi, and insect-specific viruses in mosquitoes, regulate viral transmission through gut immune regulation and microbe-derived effectors. In addition, we discuss the potential of symbiotic microbe-based interventions to suppress the transmission of mosquito-borne viral diseases.

Denisovans contributed notably to the genomes of present-day East and Southeast Asians. However, the relationship between the inhabited paleohabitats and the adaptive genetic traits related to infections in modern humans remains underexplored. This study uses geospatial techniques to analyze climatic factors associated with three Denisovan archaeological sites linked to nine specimens.

Rift Valley fever (RVF), a zoonotic mosquito-borne viral disease with erratic occurrence and complex epidemiology, results in substantial costs to veterinary and public health and national economies. Since 1985, RVF virus (RVFV) epidemiology has focused on epidemics triggered by flood-induced emergence of transovarially infected mosquitoes, following an interepidemic period during which RVFV persists primarily in floodwater Aedes spp mosquito eggs, with potential for low-level interepidemic circulation. In this Personal View, we challenge this classic framework of RVFV epidemiology, presenting instead a spectrum of RVFV dynamics ranging from epidemic to hyperendemic.

Arthropod-borne viruses (arboviruses) pose a major threat to global public health, impacting both human and animal health. Genomic characterization is important for arboviruses because it allows for an understanding of their evolution and improves timely outbreak and epidemic response. In this study, we used high-throughput sequencing and computational analyses to characterize the genomes and evolution of 46 previously unsequenced or partially sequenced arbovirus isolates collected across 23 countries between 1954 and 1984.

Zika virus (ZIKV) is a mosquito-borne flavivirus causing a major epidemic in the Americas in 2015. Dendritic cells (DCs) are leukocytes with key antiviral functions, but their role in ZIKV infection remains under investigation. While most studies have focused on the monocyte-derived subtype of DCs, less is known about conventional dendritic cells (cDCs), essential for the orchestration of antiviral adaptive immunity.

Introduction: Climate variability and non-environmental factors such as travel and migration pose an increasing risk of vector-borne infectious diseases to extratropical regions. The European Centre for Disease Prevention and Control has reported autochthonous transmissions of dengue or West Nile virus in Italy, France, Spain, and Germany. Raising awareness and implementing protective measures against mosquitoes will therefore become increasingly relevant in Germany in the future.
