Sentinel chicken surveillance reveals previously undetected circulation of West Nile virus in the Netherlands.

West Nile virus (WNV) was first detected in the Netherlands in 2020, with circulation observed in birds, mosquitoes, and humans in two geographical areas. Usutu virus (USUV) has been circulating in the Netherlands since 2016. Following the detection of WNV in the Netherlands, we investigated the possible use of petting zoos as urban sentinel sites to examine the extent of WNV and USUV circulation around the two WNV outbreak locations.

Evaluation of the use of alternative sample types for mosquito-borne flavivirus surveillance: Using Usutu virus as a model.

Wild birds are reservoirs of several zoonotic arboviruses including West Nile virus (WNV) and Usutu virus (USUV), and are often monitored as indicators for virus introduction and spread. To optimize the bird surveillance for arboviruses in the Netherlands and to explore the possibilities for citizen science in surveillance, we investigated the suitability of using alternative sample types from live and dead birds. The sensitivity of molecular detection via RT-PCR of viral RNA in feather, heart, lung, throat and cloaca swabs from dead birds, and serum, dried blood spots (DBS) and throat and cloaca swabs from live birds were compared.

Operationalizing the ECOWAS regional one health coordination mechanism (2016-2019): Scoping review on progress, challenges and way forward.

Based on recommendations from two consultative meetings held in Dakar, Senegal (2016) and Abuja, Nigeria (2017) the Economic Community of West African States (ECOWAS) implemented a Regional One Health Coordination Mechanism (R-OHCM). This study analyzed the process, challenges and gaps in operationalizing the R-OHCM in West Africa. We utilized a scoping review to assess five dimensions of the operation of an R-OHCM based on political commitment, institutional structure, management and coordination capacity, joint planning and implementation, as well as technical and financial resources.

Prioritization of zoonotic diseases of public health significance in Nigeria using the one-health approach.

Nigeria, with a population of over 190 million people, is rated among the 10 countries with the highest burden of infectious and zoonotic diseases globally. In Nigeria, there exist a sub-optimal surveillance system to monitor and track priority zoonoses. We therefore conducted a prioritization of zoonotic diseases for the first time in Nigeria to guide prevention and control efforts.
