Vector-borne diseases, such as malaria and lymphatic filariasis, are co-endemic in large parts of the world. To develop a multiplex amplification method for the simultaneous detection of multiple insect-borne infectious diseases, we used LAMP with fluorescently labeled primers to identify the SPECT2 gene of Plasmodium berghei and the cytochrome oxidase subunit I gene of Dirofilaria immitis in mosquitoes. This technique could detect as few as 100 P. berghei-infected red blood cell-equivalents or one D. immitis microfilaria. Moreover, individual species of parasites in mosquitoes could be identified when a mixture of fluorescently labeled primer sets was used. These findings suggest that the multiplex LAMP assay is sensitive and specific enough to identify parasite-bearing mosquitoes in areas where several diseases occur simultaneously. This procedure could increase the efficiency and effectiveness of arthropod-borne disease elimination programs.

Background: Mixed-species, mixed-strain plasmodia infections are known to occur in humans in malaria endemic areas. It may be surprising that to date, the extent of this complexity has not been systematically explored in high-burden countries of sub-Saharan Africa, especially in the reservoir of asymptomatic infections in all ages, which sustains transmission.
Methods: Here we take a metagenomic lens to these infections by sampling variable blood volumes from 188 afebrile residents living in high, seasonal transmission in Northern Sahelian Ghana.

: Mosquitoes harbor diverse insect-specific viruses (ISVs) frequently overlooked in arbovirus surveillance. Comprehensive characterization of ISVs is crucial for understanding their impact on host ecology and potential roles in arbovirus transmission. : Using metagenomic sequencing on Armigeres subalbatus from Yunnan, China, we identified two novel picorna-like viruses, assembled their genomes, and conducted phylogenetic analysis.

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.

Understanding why Diptera, such as mosquitoes and sand flies, feed on humans is crucial in defining them as vectors of diseases such as malaria, dengue fever, Zika virus, and leishmaniasis. Determining their attraction to humans (anthropophily) helps in assessing the risk of disease transmission, designing effective vector control strategies, and monitoring the effectiveness of existing control measures. An important question is whether they are specifically attracted to humans in preference to other mammals or whether there is something else at play.
