The Taiwan Center for Disease Control has reported a human H1N2v influenza case in a 5-year-old girl living in the central area.
She had mild illness (fever, runny nose and cough) and didn’t require hospitalization and was engaged in livestock breeding at home.
H1N2 is a low-pathogenic influenza virus that exists in pigs. It rarely spreads among people, but there are occasional reports of human infection. A total of 30 confirmed cases of H1N2v influenza worldwide from 2012 to 2021 are distributed in the Americas, with the United States reporting the most cases, followed by Brazil. Most cases have a history of pig exposure or have been exposed to a contaminated environment.
When an influenza virus that normally circulates in swine is detected in a person, it is called a variant influenza virus and is labeled with a ‘v’.
Influenza viruses such as H1N1(v) and other related variants are not unusual in swine and can be directly transmitted from swine to people and from people to swine.
When humans are in close proximity to live swine, such as in barns and livestock exhibits at fairs, movement of these viruses can occur back and forth between humans and animals.
The illnesses resulting from H1N1(v) infection are similar to seasonal influenza. Symptoms include fever, muscle aches, decreased energy, coughing, runny nose, and sore throat.
