Yellow fever virus (YFV) has a long history of impacting human health in South America. Mayaro virus (MAYV) is an emerging arbovirus of public health concern in the Neotropics and its full impact is yet unknown. Both YFV and MAYV are primarily maintained via a sylvatic transmission cycle but can be opportunistically transmitted to humans by the bites of infected forest dwelling Haemagogus janthinomys Dyar, 1921. To better understand the potential risk of YFV and MAYV transmission to humans, a more detailed understanding of this vector species' distribution is critical. This study compiled a comprehensive database of 170 unique Hg. janthinomys collection sites retrieved from the published literature, digitized museum specimens and publicly accessible mosquito surveillance data. Covariate analysis was performed to optimize a selection of environmental (topographic and bioclimatic) variables associated with predicting habitat suitability, and species distributions modelled across South America using a maximum entropy (MaxEnt) approach. Our results indicate that suitable habitat for Hg. janthinomys can be found across forested regions of South America including the Atlantic forests and interior Amazon.

“…Future outbreaks can be more widespread if the virus evolves to utilize animals like birds or rodents as e cient reservoirs since these animals are present within or are close to major human population centers. Epidemics can be further exacerbated by the widespread occurrence of Haemagogus mosquitoes, including in areas close to human communities in some countries like Trinidad and Tobago, as was noted by Ali et al (2019).…”

“…However, the possibility of other feeding hosts at Ecclesville and Mamon Village sites being the source of MAYV also cannot be discounted since avian and small mammalian species have also been reported to be associated with MAYV isolation in previous studies 37,38 . Haemagogus mosquitoes have been shown to be very attracted to humans as a blood feeding source 33,35,39 and have become well adapted to breeding in arti cial containers [40][41][42] . The forest peripherals in Mamon Village and Ecclesville are used for housing and agricultural activities 42 where humans may also serve as potential intermediary host when MAYV is in circulation.…”

“…Mus musculus RNA was also identi ed in Haemagogus samples collected from Chaguaramas and Catshill locations suggesting rodents as an alternative feeding host for these mosquitoes. A previous entomological survey 42 found Haemagogus mosquitoes present in high densities at locations in Trinidad with no known non-human primates, the reported major host of these mosquitoes [13][14][15] . Hence, the data from the current study supports previous suggestion that other animals may be serving as feeding hosts 61,62 .…”

Currently, there are increasing concerns about the possibility of a new epidemic due to emerging reports of Mayaro virus (MAYV) fever outbreaks in areas of South and Central America. Haemagogus mosquitoes, the primary sylvan vectors of MAYV are poorly characterized and a better understanding of the mosquito’s viral transmission dynamics and interactions with MAYV and other microorganisms would be important in devising effective control strategies. In this study, a metatranscriptomic based approach was utilized to determine the prevalence of RNA viruses in field-caught mosquitoes morphologically identified as Haemagogus janthinomys from twelve (12) forest locations in Trinidad, West Indies. Known insect specific viruses including the Phasi Chaoren-like and Humaiata- Tubiacanga virus dominated the virome of the mosquitoes throughout sampling locations while other viruses such as the avian leukosis virus, MAYV and several unclassified viruses had a narrower distribution. Additionally, assembled contigs from the Ecclesville location suggests the presence of a unique uncharacterized picorna-like virus. Mapping of RNA sequencing reads to reference partial or complete mitochondrial genomes showed hits against avian and rodent genomes, which putatively add to the growing body of evidence of a potentially wide feeding host-range for the Haemagogus mosquito vector.
