Researchers Discover New Virus After Inventing a ‘Mosquito Toilet’

**Innovative “Mosquito Toilet” Could Help Detect Emerging Viruses**

Researchers have made a groundbreaking advancement in monitoring vector-borne diseases with the development of a 3D-printed device designed to collect and analyse mosquito waste. This device, informally dubbed the “mosquito toilet,” builds on established techniques of monitoring wastewater for viruses that prompt public health concerns, such as COVID-19.

Dana Price, an associate professor at Rutgers University’s Center for Vector Biology, has led the charge in applying this technology to mosquitoes, notorious carriers of diseases like West Nile virus, Zika, and dengue fever. The research team’s work offers promising insights and may potentially aid in the early detection of new viral threats that could impact human health.

The researchers set up their collection device in a New Brunswick, New Jersey, yard, where they focused on capturing waste from Culex mosquitoes from September 2021 to September 2022. The work culminated in findings that were recently published in *Microbiology Spectrum*, highlighting not only the identification of known pathogens but also genetic evidence of previously unknown viruses.

Among the discoveries was evidence of Hedwig-like viruses, named after the iconic owl from the Harry Potter series. These viruses were first noted in snowy owls across Europe. Professor Price expressed surprise at this finding, stating, “We didn’t even look for it specifically. We just looked for everything, and we found Hedwig in there.”

In addition to this notable discovery, Price and his colleagues also identified the complete viral genome of the West Nile virus, and found traces of other parasites. This reinforces the necessity of comprehensive monitoring, as Price pointed out the challenge of uncovering unseen pathogens: “If you don’t look for it, you won’t find it. But what if you don’t know what to look for?”

The implications of this innovative research extend beyond mere identification of pathogens. The overarching aim is to construct a reliable surveillance system capable of testing mosquito waste continuously, providing timely alerts to health officials regarding any emerging viral threats. Price envisions a future in which this device operates autonomously in natural environments, relaying real-time data back to researchers.

As the team continues to explore this area of study, the potential for the findings is broad. Price affirmed the need for extensive data generation to challenge existing assumptions about pathogen distribution: “The more data we generate, the more we start to wonder if everything is everywhere. Although we don’t yet know how much of everything is everywhere, it may be a lot more than we realise.”

The study pushes the boundaries of entomological research and public health monitoring, creating pathways for novel approaches to manage vector-borne diseases. By focusing on the waste produced by mosquitoes, researchers hope to enhance the understanding of how these viruses circulate in environments where humans may encounter them.

Further collaboration is already underway with the New Jersey Department of Environmental Protection’s Division of Fish and Wildlife, which includes examining birds that have recently succumbed to illness, thus broadening the scope of research into other wildlife species that could serve as reservoirs for emerging pathogens.

The research team’s innovative device promises a significant step forward in the ongoing battle against illnesses transmitted by mosquitoes. As researchers continue to adapt their approaches to include modern technology, such as 3D-printed devices, they are likely to improve disease surveillance and potentially thwart health threats before they escalate into outbreaks.

With the increasing impact of climate change on disease transmission, finding effective solutions has never been more urgent. Through the harnessing of technology, researchers like Price are poised to revolutionise how public health authorities monitor and respond to vector-borne diseases, safeguarding communities from emerging health threats.
