Abstract In an epidemiologic investigation of Enterovirus (EV) infections in a Verona hospital , September 2022–September 2024, we detected EV-C105 in six pediatric patients with upper respiratory symptoms between March and May 2023. The primary objective was to describe the local incidence of EV cases. The secondary objective was to perform Sanger’s genomic characterization and the whole-genome sequencing (WGS) of EV-C105. The proportion of positive EV results was calculated based on routine molecular method testing. An available cohort of 114 underwent Sanger sequencing, and the six EV-C105 were characterized with WGS. Overall, 96% EV results were from the upper respiratory tract . The total proportion of positives in children was 83%. Out of the typed 114, 90% were Rhinoviruses and 9%, EVs . Notably, six pediatric cases were EV-C105 , placing together in a unique cluster with 99% of nucleotides belonging to the European lineage with the highest Average Nucleotide Identity, including...

The Database of Global Administrative Boundaries (GADM) used by WAHIS, provides Crespellano as the municipality corresponding to the given coordinates. As a matter of fact the location of the infected premises is the municipality of Valsamoggia Domestic cat found dead on 13 January 2025 at a family poultry farm located in the municipality of Valsamoggia (BO). As expected, the virus has the highest genetic similarity to the H5N1 virus sequenced from poultry from the same farm that tested positive on December 31st. These results confirm that the cat likely became infected following direct exposure to infected poultry at the same site where it was found dead.

{Original Article in Italian, edited and translated}  17/01/2025 13:28 Bologna – In Valsamoggia (Bo) a case of avian influenza was found in a cat . The animal lived in close contact with the poultry of a small family farm where the avian infection had already been identified which had led, as required by law, to the suppression of all the poultry present. The positivity in the cat was diagnosed by the Forlì branch of the Experimental Zooprophylactic Institute of Lombardy and Emilia-Romagna and confirmed by the National Reference Center for Avian Influenza. “Nothing new and no alarm,” commented Pierluigi Viale , professor of Infectious Diseases at the Department of Medical and Surgical Sciences at the University of Bologna and director of the Infectious Diseases Unit at the Sant’Orsola Polyclinic.  “The circulation of avian influenza is well known. Cats are already described in scientific literature as animals quite prone to contracting the ‘bird flu’ and there have been severa...

Abstract The European subtype of tick-borne encephalitis virus (TBEV-Eur; species Orthoflavivirus encephalitidis , family Flaviviridae ) was the only tick-borne flavivirus present in central Europe known to cause neurologic disease in humans and several animal species . Here, we report a tick-borne flavivirus isolated from Alpine chamois (Rupicapra rupicapra rupicapra) with encephalitis and attached ticks , present over a wide area in the Alps . Cases were detected in 2017 in Salzburg, Austria , and 2023 in Lombardy and Piedmont, Italy . The virus strains exhibit 94.8–97.3% nucleotide identities to each other and are more closely related to Louping ill viruses (LIV; Orthoflavivirus loupingi ; 90–92% identities) than to TBEV-Eur (less than 88%). The chamois-derived virus strains, tentatively termed “ Alpine chamois encephalitis virus ”, form a well-supported independent genetic clade with Spanish goat encephalitis virus , clearly separated from other LIV. This supports its designation a...

 {Excerpt} He had recently returned from a trip to Congo and died on Monday evening from a suspected case of hemorrhagic fever . The victim is a 55-year-old man from Trevignano , in the province of Treviso. The news was communicated by the Public Health Hygiene Service of the Azienda Ulss 2 Marca trevigiana and diagnostic tests are underway in collaboration with the Spallanzani Institute of Rome to trace the origins of the death.

Abstract The influenza A H1N1pdm09 virus continues to be a significant pathogen , posing potential risks to both animal and human health due to its zoonotic potential . Italy , which has one of the largest swine populations in Europe , plays a crucial role in monitoring the evolution of influenza viruses in livestock. This study aims to address the existing knowledge gaps regarding the genetic diversity and transmission dynamics of H1N1pdm09 circulating in Italian swine populations. Utilizing whole genome sequencing and dynamic modeling , we conducted a comprehensive analysis of virus samples collected from swine farms across Italy. Our results reveal that multiple independent viral introductions have occurred into the country, with most cases resulting in self-limited infections and limited onward transmission . However, six distinct transmission clusters were identified, suggesting instances of sustained viral spread. These clusters were found across multiple regions of Italy, highli...
