Influenza H3N2v

H3N2v is a non-human influenza virus that normally circulates in pigs and that has infected humans. Spread from infected pigs to humans is thought to happen in the same way that seasonal influenza viruses spread between people: mainly through infected droplets when an infected pig coughs or sneezes.

Symptoms include fever and respiratory symptoms, body aches, nausea, vomiting, and diarrhea. People at high risk of developing complications from the virus are children younger than 5 years, people 65 years and older, pregnant women, and people with long-term health conditions (like asthma, diabetes, weakened immune systems, and neurological or neurodevelopmental conditions).
