  Abstract Avian influenza A(H9N2) has been circulating in poultry across Asia, the Middle East, and Africa, posing human health risks . In Ghana , it has co-circulated among poultry with influenza A ( H5N1 ). This report describes Ghana’s first confirmed human case of avian influenza A(H9N2) virus infection in a two-year-old boy from Upper East Region , identified through active respiratory surveillance . Molecular and genomic analyses confirmed the virus was of the G1 lineage , closely related to other West African strains , with mammalian adaptive mutations known to increase human infection potential. The child experienced mild symptoms , received outpatient care, and recovered. Health authorities conducted epidemiological investigations . No source was identified for the child’s infection; no additional human infections were detected. This case highlights the importance of robust avian influenza surveillance in animals and humans, particularly in regions with human-animal inter...

  Neurological-respiratory disease in backyard domestic birds raised in a farm with partial laboratory results of H5 avian influenza virus . Zoning was implemented for the control of the outbreak with stamping out measures for all affected and contact birds on the farm, and surveillance will be carried out in the perifocal and protection areas. A body of water representing a possible place of contact between domestic and wild birds is located on the premises. Source: WOAH,  https://wahis.woah.org/#/in-review/6755 ____

  Abstract Mosquito-borne diseases are deeply embedded within ecological communities, with environmental changes—particularly climate change—shaping their dynamics . Increasingly intense droughts across the globe have profound implications for the transmission of these diseases , as drought conditions can alter mosquito breeding habitats , host-seeking behaviours and mosquito–host contact rates . To quantify the effect of drought on disease transmission, we use West Nile virus as a model system and leverage a robust mosquito and virus dataset consisting of over 500 000 trap nights collected from 2010 to 2023, spanning a historic drought period followed by atmospheric rivers. We pair this surveillance dataset with a novel modelling approach that incorporates monthly changes in bird host community competence , along with drought conditions , to estimate the effect of drought severity on West Nile virus risk using panel regression models. Our results show that while drought decreases ...
