Influenza is one of the most contagious viral infections of the nose, throat and lungs. Symptoms include fever, extreme tiredness, sore throat, stuffy nose and muscle aches. Some infected people will also develop gastrointestinal symptoms such as nausea, vomiting and diarrhea; however, the molecular mechanisms involved are unclear. A new study in mice shows that influenza virus infection in the lungs alters the gut microbiota and immune responses via type I interferons.
