H3N2v

You may have heard about cases of swine flu in certain U.S. states this year. While the majority of cases are occurring in Ohio and Indiana, all influenza viruses have the capacity to change and it's possible that this virus may become widespread, according to the CDC.

There have been hundreds of cases of H3N2v infection (a swine flu variant) in the U.S. so far this year. Human to human transmission remains rare with most the result of exposure to swine.

As with other influenza infections, certain people, including young children, elderly persons, pregnant women and people with long term medical conditions, are at greater risk of complications than others.

Specific steps to prevent the spread of influenza between people and pigs

• Wash your hands frequently with soap and running water before and after exposure to animals.
• Never eat, drink, or put things in your mouth while in animal areas, and don't take food or drink into animal areas.
• Children younger than 5, people 65 and older, pregnant women, and people with certain chronic medical conditions (such as, asthma, diabetes, heart disease, weakened immune systems, and neurological or neurodevelopmental conditions) are at high risk for serious complications if they get influenza. People with these risk factors should consider avoiding exposure to pigs and swine barns this summer, especially if sick pigs have been identified.
• If you have animals - including swine - watch them for signs of illness, and call a veterinarian if you suspect they might be sick.
• Avoid close contact with animals that look or act ill, when possible.
• Avoid contact with pigs if you are experiencing flu like symptoms.
