I’m pleased to announce the launch of #DeZi ! a global collaboration funded by @wellcometrust.bsky.social and led by @imperialcollegeldn.bsky.social that brings together teams across Africa, Asia & the Americas to advance our understanding of #dengue & #Zika viruses Thread DeZi in brief 👇
Dear network, I’m pleased to announce the launch of hashtag#DeZi (Dengue and Zika Immunology and Genomics Multi-Country Network) – a global collaboration that I’m part of,  bringing together leading teams across Africa, Asia, and the Americas to advance our understanding of dengue and Zika viruses.

🔬 DeZi in brief:

DeZi is a global initiative led by Imperial College London and Nuno R. Faria and supported by the Wellcome Trust, Temasek Foundation and the National Environment Agency.

It integrates genomics, serology, and modelling to map the burden, transmission, and evolution of dengue and Zika viruses.
 
By combining innovation with equitable partnerships, DeZi aims to:
• accelerate the adoption of improved diagnostics
• strengthen regional laboratory capacity and South–South collaborations
• enhance preparedness for future arboviral epidemics in a changing climate

With its open-access resources and policy engagement activities DeZi will help countries integrate the surveillance of dengue, Zika, and other mosquito-borne viruses into routine national health systems, turning collaboration into capacity, and data into effective policymaking.

🌍 Partners span research institutions and public-health laboratories in more than 15 countries across Africa, Asia, and Latin America, working closely with UKHSA, Yale University, WHO, and networks such as UNITEDengue, CREID, and ARTIC2.0.

Anti-dengue virus antibodies that elicit complement-mediated lysis of Zika virion correlate with protection from severe dengue disease
Dias et al. show that cross-reactive anti-dengue virus antibodies in pre-infection plasma that mediate complement-dependent virolysis of Zika virus correlate with protection from subsequent severe den...

Check out our paper in @natcomms.nature.com ! We explored the link between pre-existing neutralizing antibody (nAb) titers and dengue disease protection & how different cell substrate and virus maturation state influences the measurement of nAb titers rdcu.be/eOfXW

Protection against symptomatic dengue infection by neutralizing antibodies varies by infection history and infecting serotype
Nature Communications - There is still a need to improve understanding of dengue-specific immunity. Here, by analyzing the antibody response in a pediatric cohort the authors show that the...

Monumental effort led by Peter Simmonds and Jens Kuhn to reorganize the Family Flaviviridae based on analysis of RNA-directed RNA polymerase (RdRP) hallmark gene sequences is finally out. Enjoy reading. #ICTV @utmbhealth.bsky.social @astmh.bsky.social @sbvirologia.bsky.social
