In November 2023, a case of human infection with the A(H1N2)v virus was detected in the United Kingdom.

Situation Description

Details regarding this case are not yet available. The A(H1N2)v virus is a variant of the influenza A virus and has previously been identified in humans in other parts of the world, including the United States and France.

What is the A(H1N2)v Virus?

The A(H1N2)v virus is a variant of the influenza A virus. Influenza A viruses are divided into subtypes based on two proteins on the surface of the virus: hemagglutinin (H) and neuraminidase (N). A(H1N2)v viruses are rarely detected in humans, but it is not unknown. Most identified cases of A(H1N2)v virus infection in humans have had mild disease symptoms.

What are the Symptoms of A(H1N2)v Virus Infection?

Symptoms of A(H1N2)v virus infection are similar to those of seasonal flu and may include fever, cough, sore throat, muscle aches, headache, shortness of breath, diarrhea, nausea, dizziness, and fatigue.

How Can You Get Infected with the A(H1N2)v Virus?

Most cases of A(H1N2)v virus infection in humans have occurred after contact with pigs. However, there is no evidence that the A(H1N2)v virus is easily transmitted from person to person.

What are the Preventive Measures?

Similar to other influenza viruses, avoiding close contact with pigs and maintaining good hand hygiene can help prevent infection with the A(H1N2)v virus. People who have contact with pigs should wear appropriate protection, such as masks and gloves, to minimize the risk of infection.

What’s Next?

Considering the potential impact on public health, A(H1N2)v virus infections in humans must be closely monitored. In this case, no evidence of sustained human-to-human transmission was reported, the disease was mild, and no further spread of the influenza virus in the community was identified.
