The (digestive) path less traveled: influenza A virus and the gastrointestinal tract | mBio Seasonal influenza A viruses (IAVs) are highly transmissible respiratory pathogens in humans, with virus replication typically restricted to the respiratory tract. There is a wide clinical spectrum of respiratory and non-respiratory complications associated with seasonal and novel (e.g., zoonotic-origin) IAV infections (1, 2). Human infections with IAVs can lead to complications affecting multiple organ systems, including the brain, heart, eyes, blood, and other tissues (1). Gastrointestinal (GI) symptoms (such as diarrhea, vomiting, and abdominal pain) can occur with human IAV infections caused by seasonal or novel IAVs (3, 4). Diarrhea has also been reported following influenza B virus infection in children, highlighting that GI symptoms are not unique to IAV infections (5, 6). https://journals.asm.org/doi/10.1128/mbio.01017-25?utm_source=literatum&utm_medium=email&utm_campaign=alert-emails
