However, you should take steps to protect yourself against H3N2v if you do attend agricultural fairs, particularly where swine are present.
If you are at high risk of serious flu complications , avoid pigs and swine barns at the fair. People with health or age factors that put them at high risk for serious flu complications should avoid pigs and swine barns. As always, take time to get a seasonal influenza vaccine as soon as flu vaccine becomes available in your community, to protect yourself from the seasonal influenza viruses that are most likely to circulate this season.
No, you cannot always tell if a pig has a flu virus just by looking at the pig. Some pigs infected with influenza may have no signs of illness at all. Skip directly to site content Skip directly to page options Skip directly to A-Z link.

What are the symptoms of H3N2v? Some influenza A subtypes that you may be familiar with include H1N1 sometimes known as swine flu and H3N2. Typically, flu seasons that are dominated by H3N2 activity are more severe, particularly among at-risk groups such as older adults and younger children. There were reported pediatric deaths , mostly in unvaccinated children. There were an estimated pediatric deaths, with reported pediatric deaths. If you received the vaccine, your chance of needing professional medical attention for the flu were reduced by 40 percent.
When broken down by virus, the vaccine was 65 percent effective against H1N1, 25 percent effective against H3N2, and 49 percent effective against influenza B. The flu symptoms caused by H3N2 are similar to symptoms caused by other seasonal influenza viruses.
Symptoms typically appear suddenly and can include:. The flu has some symptoms in common with other respiratory illnesses, such as the cold. A healthcare professional can perform a lab test to confirm whether you have the flu or some other illness. However, if you experience flu-like symptoms during the traditional flu season October to May , they may diagnose you with the flu even without the help of a lab test.
Each year, the annual flu vaccine protects against either three or four strains of flu. These are known as trivalent and quadrivalent vaccines, respectively.
An H1N1, H3N2, and influenza B strain are included in the trivalent vaccine, while an extra influenza B strain is included in the quadrivalent vaccine. According to the CDC, the flu vaccine reduces the risk of flu illness in the general population by between 40 and 60 percent during most flu seasons when the vaccine strains are a good match to circulating strains.
This can be explained in a couple of ways. First, while all flu viruses mutate from year to year, H3N2 viruses tend to undergo more genetic changes. Only your healthcare provider can diagnose you with the flu. A diagnosis is made based on symptoms you are experiencing, a physical exam, and sometimes a rapid flu test that is performed using a nasal or throat swab.
If your healthcare provider determines that you have the flu, treatment can vary depending on your age, overall health, and length of time that you have been sick.
Antiviral medications , such as Tamiflu or Relenza, can help shorten the severity of your symptoms or the duration of your illness. They are most effective if taken within the first 48 hours of the onset of symptoms. If you have been sick longer than 48 hours, your healthcare provider may decide that taking them won't really benefit you.
You may also be told that you don't need an antiviral medication if you are not at high risk for flu complications. Even without antiviral medications, there are things you can do to help yourself feel better. Taking over-the-counter medications to alleviate your symptoms, getting plenty of rest, and drinking lots of fluids are important things you can do to give your body a chance to recover.
Taking antibiotics won't help unless you have a secondary bacterial infection, as these drugs don't kill viruses. Influenza is a difficult virus. It changes so frequently that it is hard to identify and treat—and even harder to develop the vaccine months in advance of flu season.
H3N2 is one subtype of the influenza virus that often causes significant illness. When it is the dominant strain causing illness during a given year, those flu seasons are often more severe. It's important to take steps to protect yourself and your family from the flu each year, no matter which strain is making people sick.
