A systematic surveillance against influenza A viruses (IAVs) in the population is essential, considering their role as IAV mixing vessels. However, the viral circulation in wild species is poorly investigated in comparison to the knowledge of IAV infection dynamics in domestic pigs. This study investigated the circulation and the genetic diversity of wild boars' IAVs detected in the Emilia-Romagna region (2017-2022).

- - Swine are crucial for the ecology of influenza A viruses, acting as mixing vessels for various strains, with H1N1, H3N2, and H1N2 being prevalent globally.
- - A study in Northern Italy analyzed 672 IAV-positive samples from pig farms (2017-2020) and found high genetic diversity in H1N1 and H1N2 strains, while H3N2 showed stability in its genetic patterns.
- - Notable changes included increasing variability in HA-1C strains and the discovery of an antigenic variant cluster in HA-1A strains in 2020, highlighting the need for ongoing surveillance due to the potential zoonotic risks of these evolving viruses.
Article Synopsis
- Influenza D virus (IDV) has been increasingly found globally, with cattle being the primary carriers and three genetic clusters identified: D/OK, D/660, and D/Japan.
- A study in Northern Italy from early 2018 to mid-2019 detected IDV in 74 out of 725 bovine farms, revealing the presence of the D/660 strain, which was previously unknown in Europe.
- A unique reassortant strain was also found, indicating diverse IDV genetic patterns, emphasizing the importance of ongoing monitoring to understand IDV's spread and impacts on cattle health.
