Influenza A virus subtype H3N2 (also H3N2) is a subtype of viruses that cause influenza (flu). H3N2 viruses can infect birds and mammals. In birds, humans, and pigs, the virus has mutated into many strains. H3N2 is increasingly abundant in seasonal influenza, which kills an estimated 36,000 people in the United States each year.
This year's influenza outbreak is already the most widespread on record since health officials began keeping track about a dozen years ago, with millions of Americans being infected by emerging and current strains such as the dominant H3N2.
Alphabet’s venture arm called Google Ventures earlier is one of the supporters of a mega projects that is developing a vaccine for flu that is safe and effective. Vaccitech from United Kingdom is working towards development of the vaccine and Alphabet has shown its support by contributing $27.6 million in new funding. The funds would be used conduct clinical trials and try the new vaccine.
As flu season picks up steam across the country, it's important for people to be tested very early after symptoms that are compatible with influenza start, since there are effective treatments that can limit severe, life-threatening disease and curtail transmission to others.
NHS Dumfries and Galloway has reassured the public over the number of “Aussie flu” cases seen in the region, saying that the H3N2 flu strain is a standard one that has previously been commonplace in Scotland.
Lactic acid bacteria, commonly used as probiotics to improve digestive health, can offer protection against different subtypes of influenza A virus, resulting in reduced weight loss after virus infection and lower amounts of virus replication in the lungs, according to a study led by Georgia State University.
A collaborative research and development partnership between researchers at the University of Georgia and Sanofi Pasteur, the largest influenza vaccine manufacturer in the world, has resulted in the identification of a vaccine candidate that protects against multiple co-circulating strains of H3N2 influenza isolated over five seasons following testing in mouse and ferret models.
Flu season is here. The contagious respiratory illness caused by viruses that infect the nose, throat and lungs can cause mild to severe illness and at times may lead to death. People of every age -; including people in good health -; are at risk for flu.
Each year, public health officials monitor the spread of influenza to identify which flu strains need to go into that year's vaccines and where outbreaks will occur. But it can be difficult to predict how bad a particular flu season will be until people actually start getting sick.
A boosting skin vaccination with a biodegradable microneedle patch and protein constructed from sequences of influenza virus subtypes could improve the effectiveness of conventional influenza vaccines, according to a study led by Georgia State University.
Scientists at The Scripps Research Institute have shown that for the virus that causes the flu, two wrongs can sometimes make a right.
Hundreds of dogs are hit with dog flu over the last couple of years. In a new development, this flu strain has hit Florida for the first time. At least a dozen dogs have been down with the virus according to a report issued by the University of Florida’s College of Veterinary Medicine on the 31st of May 2017.
New findings challenge the traditional policy of replacing old strains in existing human influenza vaccines with recent variants with only minimal changes.
The high-dose flu vaccine appeared to be more effective at preventing post-influenza deaths among older adults than the standard-dose vaccine, at least during a more severe flu season, according to a large new study of Medicare beneficiaries published in The Journal of Infectious Diseases.
To infect its victims, influenza A heads for the lungs, where it latches onto sialic acid on the surface of cells.
This year, everyone will have to roll up their sleeves and receive the flu shot via injection, as the Centers for Disease Control and Prevention no longer recommends the nasal flu mist vaccine due to ineffectiveness.
An international team of scientists have designed a new generation of universal flu vaccines to protect against future global pandemics that could kill millions.
A computer model developed by scientists at the University of Chicago shows that small increases in transmission rates of the seasonal influenza A virus (H3N2) can lead to rapid evolution of new strains that spread globally through human populations.
Influenza A viruses are responsible for seasonal disease outbreaks in humans. Influenza A also circulates among bird and some mammal populations and periodically crosses between species.
During the 2014-15 flu season, the poor match between the virus used to make the world's vaccine stocks and the circulating seasonal virus yielded a vaccine that was less than 20 percent effective.
Minor variants of flu strains, which are not typically targeted in vaccines, carry a bigger viral punch than previously realized, a team of scientists has found. Its research, which examined samples from the 2009 flu pandemic in Hong Kong, shows that these minor strains are transmitted along with the major strains and can replicate and elude immunizations.
