What is H3N2v?

What is H3N2v?

H3N2v is a non-human influenza virus that normally circulates in pigs and that has infected humans. Viruses that normally circulate in pigs are “swine influenza viruses.” When these viruses infect humans, they are termed “variant” viruses.

How is H3N2 transmitted?

Spread from infected pigs to humans is thought to happen in the same way that seasonal influenza viruses spread between people – mainly through infected droplets created when an infected pig coughs or sneezes. If the droplets land in your nose or mouth, or you inhale them, you can be infected.

What type of virus is H3N2?

Influenza A virus subtype H3N2 (A/H3N2) is a subtype of viruses that causes influenza (flu). H3N2 viruses can infect birds and mammals. In birds, humans, and pigs, the virus has mutated into many strains. In years in which H3N2 is the predominant strain, there are more hospitalizations.

What is H1N1 and H3N2?

Currently, Influenza A (H1N1) and Influenza A (H3N2) are the circulating seasonal Influenza A virus subtypes. This seasonal A (H1N1) virus is the same virus that caused the 2009 influenza pandemic.

Is H1N1 worse than H3N2?

Conclusions: Influenza A H3N2 infection was more severe than A H1N1 or B in terms of fever, leukopenia, and C-reactive protein. Myalgia and other symptoms such as fever, headache, general malaise and sore throat were equally frequent in influenza A H3N2, A H1N1, and B infections.

Which virus is responsible for bird flu?

H5N1 is a type of influenza virus that causes a highly infectious, severe respiratory disease in birds called avian influenza (or “bird flu”).

Is H3N2 a swine flu?

Regularly circulating in North American swine, common strains of swine influenza include H1N1, H1N2 and H3N2.

Is there a vaccine for H3N2 virus?

Vaccine for H3N2 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.

How bad is H3N2?

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.

Is there such a thing as H3N2v in humans?

No, H3N2v is different. H3N2v is a variant virus that is in pigs and has infected some humans.

What are the symptoms of the H3N2 virus?

What are the symptoms of H3N2v? Symptoms of H3N2v infection are similar to those of seasonal flu viruses and can include fever and respiratory symptoms, such as cough and runny nose, and possibly other symptoms, such as body aches, nausea, vomiting, or diarrhea. Why is CDC concerned about H3N2v? CDC is concerned about H3N2v for a few reasons.

When was H3N2 virus first detected in humans?

In 2011, a specific H3N2 virus was detected with genes from avian, swine and human viruses and the 2009 H1N1 pandemic virus M gene. The virus was circulating in pigs in 2010 and was first detected in people in 2011. The acquisition of the 2009 M gene may make this virus infect humans more easily than is typical for other swine influenza viruses.

How many people have been infected with H3N2?

The acquisition of the 2009 M gene may make this virus infect humans more easily than is typical for other swine influenza viruses. The most up to date information about H3N2v cases, hospitalizations and deaths that have been reported to CDC is available at: Case Count: Detected U.S. Human Infections with H3N2v by State since August 2011.
