Periodic Reporting for period 2 - PREPARE4VBD (A Cross-Disciplinary Alliance to Identify, PREdict and prePARe for Emerging Vector-Borne Diseases)
Periodo di rendicontazione: 2023-03-01 al 2024-08-31
The consortium is highly multidisciplinary and consist of 10 complementary partner institutions in Europe and Africa, including leading capacities in mosquito- tick- and snail-borne diseases of livestock and humans.
Other key scientific highlights in the current period include the development of a Global Vector Database (GVD) for centralizing vector data; the creation of several non-invasive, on-site suitable diagnostic tools for early vector and vector borne disease detection; the establishment of a core tick sample cohort for genomic analyses; implementation of a strong ex vivo system for VBD susceptibility testing following the RRR principles; development and comparison of various statistical and transmission models for forecasting the mosquito-borne viral disease Rift Valley Fever (RVF). The project has furthermore developed and executed two summer-schools, the latest on project developed molecular diagnostic tools for vectors and vector-borne pathogens and an engaging early career researcher poster session that successfully accomplished at the annual meeting at icipe, Kenya in February 2024. The project has also successful completed of its 3rd Annual project meeting, held in Kenya in February 2024. The meeting was attended by almost 50 delegates from eight different countries and 10 partner Institutions, including leading experts and early career researchers in vector-borne disease research in Africa and Europe. Overall, the PREPARE4VBD summer-schools and project meetings have so far successfully served to facilitate knowledge transfer and collaborations among the project partners and beyond, and thus playing a key role in reducing barriers and silos across different vector- and vector borne disease research fields.
The project aims to continue disseminating its findings widely, culminating in a final meeting and stakeholder outreach event in Uganda in May 2025.
Although it is still early to see the full impact on socio-economics and policy, significant progress has already been made. The project has compiled extensive data on disease occurrences of its target diseases and their vector species, which includes the creation of a Global Vector Database (GVD) for centralizing vector data and mapping disease vectors across Africa. This has already improved knowledge and will help develop stronger surveillance systems. The project has also created new maps to assess the risk of spread of diseases and their vectors under climate change scenarios. An unexpected discovery of an Ixodes tick species in Kenya, known mainly from Europe and previously only found on migratory birds, could have significant implications for disease control in the region. Further studies are needed to understand this better.
To improve rapid on-site detection of disease vectors, the project has developed three new diagnostic tools. These include an automated microscope device for detecting snail-borne infections, a quick PCR test for pathogens in livestock blood and tick fluids, and an environmental DNA method for detecting liver fluke parasites in environmental samples. These tools have been demonstrated to partners and stakeholders, with further dissemination expected via webinars and at the final meetings.
The project aims to improve the prevention and control of target diseases. Early efforts in Uganda and Tanzania have already guided strategies to combat fascioliasis, a disease affecting both humans and livestock. These strategies include health education campaigns, improved access to clean water, distribution of treatment drugs, and strengthened veterinary services. The project has also led to the first detection of liver fluke infections in humans in Uganda, highlighting the need for better prevention and control policies.
The tools and models developed by the project are cost-effective and can detect multiple species in one sample, which can be preserved on-site. This will help target resources more effectively for controlling diseases and vectors in the long run.
