Mosquito-borne arboviruses: the rising global threat

An increasingly interconnected world with burgeoning tourism, travel, and trade has brought with it not just a prodigious daily shunt of people and cargo across the planet, but also the potential for pathogen and vector stow-away to colonize new grounds. Behold Covid-19, only the most recent example, but by far not the only offender in the witness box. Multiple mosquito-borne arboviruses have escaped their ancestral homes to entrench themselves with tragic effect in many countries across the globe. Think Zika, Chikungunya, dengue, yellow fever, West-Nile virus, and others. This is the tip of the iceberg…a Pandora’s Box of silent and stealthy viruses lurk in primate and bird hosts in the jungles…

 Mosquito-borne arboviruses: the rising global threat

Climate change: increased urbanization, poverty, lack of access to clean water hence storage of water will become multiplier for arboviral infections.


ArboNET is the national arboviral surveillance system managed by CDC and state health departments. In addition to human disease, ArboNET maintains data on arboviral infections among presumptive viremic blood donors, veterinary disease cases, mosquitoes, dead birds, and sentinel animals.

Arbovirus Research Consortium

The overall goal of the Arbovirus Research Consortium is to assess drivers responsible for arbovirus emergence and spread. We capitalize on an exceptionally large global network of ongoing clinical research partners and blood banks.


This group of viruses is transmitted by arthropods, mainly mosquitos, ticks and sandflies. Some of these viruses cause viral hemorrhagic fever, some meningitis/ encephalitis. Dengue virus is the most common human pathogen in the group of arboviruses. Chikungunya virus, Tickborne encephalitis virus, West Nile-virus, Crimean-Congo virus, Yellow fever virus (YFV) and Japanese encephalitis virus are important human pathogens as well.
