H3N2v Flu
The H3N2v flu, also known as the variant influenza A (H3N2v) virus, is a subtype of the influenza A virus that is typically found in pigs but can be transmitted to humans.
Transmission and Risk Factors
H3N2v flu viruses are usually spread from pigs to people through close contact with infected pigs, such as at agricultural fairs or petting zoos. The risk of infection is higher for people who work with pigs or have close contact with them. Human-to-human transmission of H3N2v flu viruses can occur, but it is relatively rare.
Symptoms
The symptoms of H3N2v flu are similar to those of seasonal influenza and may include:
- Fever
- Cough
- Sore throat
- Runny or stuffy nose
- Body aches
- Headache
- Chills
- Fatigue
- Diarrhea and vomiting (more common in children)
Complications
Certain groups of people are at higher risk for complications from H3N2v flu, including:
- Children under the age of 5
- Adults 65 years and older
- Pregnant women
- People with certain chronic health conditions, such as asthma or heart disease
Diagnosis and Treatment
H3N2v flu can be diagnosed using a variety of tests, including rapid influenza diagnostic tests (RIDTs) and molecular assays. Treatment for H3N2v flu is typically focused on relieving symptoms and may include:
- Antiviral medications, such as oseltamivir or zanamivir
- Pain relievers and fever reducers, such as acetaminophen or ibuprofen
- Cough suppressants and expectorants
Prevention
To reduce the risk of H3N2v flu transmission, people can take the following precautions:
- Avoid close contact with pigs or areas where pigs are present
- Wash hands frequently with soap and water
- Avoid touching eyes, nose, and mouth
- Cover mouth and nose with a tissue when coughing or sneezing
- Get vaccinated against seasonal influenza
Vaccination
There is no specific vaccine available for H3N2v flu, but the seasonal influenza vaccine may provide some protection against variant influenza viruses. The Centers for Disease Control and Prevention (CDC) recommends that people at high risk for complications from influenza receive the seasonal influenza vaccine each year.
