{Automatic translation from Chinese, edited} [Xinhua News Agency Micro Special] Due to the outbreak of avian influenza in many places, the Andalusia Autonomous Region in southern Spain has temporarily closed a number of parks and other attractions in recent days, including two attractions included in the UNESCO World Heritage List , and the infected animals have been killed at relevant locations. According to AFP, Seville City Hall announced on social media on the 11th that the Maria Luisa Park in the city center was closed due to the discovery of dead birds . The park will clean up the dead animals and disinfect them. The city recently closed three other parks where dead birds were found, including a World Heritage site. Catalina Garcia, an environmental official for the Andalusian autonomous region, said on social media that three outbreaks of avian influenza were detected in wild birds in Doñana National Park , a World Heritage site, and the affected birds were culled. The national ...

Abstract The zoonotic transmission of bat coronaviruses poses a threat to human health. However, the diversity of bat-borne coronaviruses remains poorly characterized in many geographical areas. Here, we recovered eight coronavirus genomes by performing a metagenomic analysis of fecal samples from hundreds of individual bats captured in Spain , a country with high bat diversity. Three of these genomes corresponded to potentially novel coronavirus species belonging to the alphacoronavirus genus . Phylogenetic analyses revealed that some of these viruses are closely related to coronaviruses previously described in bats from other countries, suggesting a shared viral reservoir worldwide. Using viral pseudotypes, we investigated the receptor usage of the identified viruses and found that one of them can use human ACE2 , albeit with lower affinity than SARS-CoV-2. However, the receptor usage of the other viruses remains unknown. This study broadens our understanding of coronavirus diversity...

Abstract Since 2021, highly pathogenic avian influenza (HPAI) A(H5N1) clade 2.3.4.4b virus has affected wild bird populations globally . Griffon vultures (Gyps fulvus), a species hitherto considered unexposed, experienced an HPAI H5N1 outbreak in 2022 in southern Europe , leading to moderate mortality and reduced breeding success . The integration of virological, serologic, phylogenetic, and ecologic data revealed a short yet intense viral circulation and a probable common source of infection . The dissemination across Spain and France was likely caused by frequent interpopulation movements of birds. This integrated overview of the 2022 HPAI outbreak in vultures provides novel insights into the role of large-scale movements of wild birds in the spread of such disease. Understanding the epidemiologic dynamics of HPAI H5N1 in these scavenger species is crucial because the birds play vital roles in ecosystem functioning. Their susceptibility to this virus highlights potential broader ecol...

Abstract A reemergence of parvovirus B19 infections in Spain in early 2024 prompted a 10-year review of the virus at a tertiary center. We identified 8 case-patients with neurologic manifestations who had parvovirus B19 in cerebrospinal fluid . Early recognition and management of parvovirus B19–associated neurologic conditions will help yield favorable outcomes.

Highlights •  In a landscape of a very narrow arsenal of influenza antivirals, resistance mutations are a significant threat. •  Resistance mutations were present in 0.5-5% in A and B influenza viruses during the last 15 years. •  However, S247N resistance mutation in the NA gene sharply increased during 2023-2024 season. •  While this mutation does not confer strong resistance by itself, their fixation could increase the risk of resistance in the future if other resistance mutations appears or get fixed together with it. Abstract The therapeutic arsenal against influenza is extremely limited and resistance often arises due to the emergence of mutations , especially in the neuraminidase (NA) gene. This study aimed to evaluate the evolution of NA mutations over 15 years in Spain . To do so, we used the GISAID database from which we downloaded a total of 11,125 influenza A(H1N1)pdm09, A(H3N2), B/Victoria and B/Yamagata NA virus sequences , and analyzed the resistance m...
