West Nile virus can be transmitted within mosquito populations through infectious mosquito excreta.

Understanding the transmission routes of arboviruses is key to determining their epidemiology. Here, we tested whether West Nile viruses (WNVs) are transmitted through mosquito excreta. First, we observed a high concentration of infectious units per excreta, although viruses were short lived.

Seroprevalence study in humans and molecular detection in Rhipicephalus sanguineus ticks of severe fever with thrombocytopenia syndrome virus in Thailand.

Severe fever with thrombocytopenia syndrome virus (SFTSV) is an emerging tick-borne virus with a mortality rate of up to 30%. First identified in China in 2009, it was later reported in other Asian countries, including Thailand in 2020. SFTSV has been detected in several tick species, including Rhipicephalus sanguineus, known for infesting dogs.

assessment of cutaneous immune responses to mosquito salivary gland extract and dengue virus in Cambodian individuals.

Dengue virus (DENV) poses a global health threat, affecting millions individuals annually with no specific therapy and limited vaccines. Mosquitoes, mainly and worldwide, transmit DENV through their saliva during blood meals. In this study, we aimed to understand how mosquito saliva modulate skin immune responses during DENV infection in individuals living in mosquito-endemic regions.

Global seroprevalence of Zika virus in asymptomatic individuals: A systematic review.

Background: Zika virus (ZIKV) has spread to five of the six World Health Organization (WHO) regions. Given the substantial number of asymptomatic infections and clinical presentations resembling those of other arboviruses, estimating the true burden of ZIKV infections is both challenging and essential. Therefore, we conducted a systematic review and meta-analysis of seroprevalence studies of ZIKV IgG in asymptomatic population to estimate its global impact and distribution.

Viral Components Trafficking with(in) Extracellular Vesicles.

The global public health burden exerted by viruses partially stems from viruses' ability to subdue host cells into creating an environment that promotes their multiplication (i.e., pro-viral).
