Content about Influenza A virus subtype H3N2

NEW YORK — This year's virulent flu season driven by a predominant H3N2 bug has people hitting their drug stores in droves in search of symptomatic relief, suggested an article published online by Forbes Monday. 

NEW YORK — This year is turning out to be a strong cough and cold season even though there are more flu shots being administered at retail, and those flu shots are a pretty good match to the popular strains this year — 99.4% of the H3N2 influenza viruses tested matched one of the three components of the 2012 to 2013 Northern Hemisphere influenza vaccine. Overall, for the four weeks ending Dec. 30, sales of remedies for sore throats and cough syrups were up 12.5% and 26.2%, respectively, according to SymphonyIRI Group data as measured across all channels. 

LONDON — The Food and Drug Administration has approved a new four-strain flu vaccine made by GlaxoSmithKline, the drug maker said.

GSK announced the approval of its Fluarix Quadrivalent (influenza virus vaccine) for children and adults against seasonal influenza subtypes A and B. The company said the vaccine was the first for intramuscular injection that protects against four strains of the virus.

ATLANTA — The influenza season is officially underway as flu incidence is already above the national threshold, Thomas Frieden, director of the Centers for Disease Control and Prevention, told reporters during a teleconference Monday. "This is the earliest regular flu season we've had in nearly a decade, since the 2003-2004 flu season," he said. "That was an early and severe flu year, and while flu is always unpredictable, the early nature of the cases as well as the specific strains we're seeing suggest that this could be a bad flu year."

 SWIFTWATER, Pa. — Sanofi Pasteur on Thursday announced it has filed for approval of a four-strain flu shot to the Food and Drug Administration. An action date is anticipated in the second quarter of 2013. 

WOONSOCKET, R.I. — CVS/pharmacy and MinuteClinic have announced that flu vaccinations are now available at all of their locations nationwide with more than 20,000 immunizing healthcare professionals at CVS/pharmacy and MinuteClinic available to provide the preventive healthcare service.

ATLANTA — The Centers for Disease Control and Prevention on Friday reported 12 additional human infections with influenza A (H3N2) variant virus in three states, comprising of one case in Hawaii, 10 cases in Ohio and one case in Indiana. The H3N2v virus contains the M gene from the 2009 H1N1 virus, as have the previous 17 cases detected since July 2011.

ATLANTA — Children under the age of 10 years old may be especially susceptible to a new strain of influenza, according to an article published Friday in the Center for Disease Control and Prevention's "Morbidity and Mortality Weekly Report."

WASHINGTON — The Centers for Disease Control and Prevention said that the Food and Drug Administration has recommended that the flu vaccine for the 2011-2012 season protect against the same strains as it did this year.

The FDA's Vaccines and Related Biological Products Advisory Committee recommended that the vaccine will protect those immunized against H1N1, H3N2 and a type of influenza-B virus, the same formulation as this past season's vaccine.

ATLANTA — The Centers for Disease Control and Prevention on Friday updated the nation’s influenza status. Nine states are reporting high influenza-like activity (a metric that captures the severity of a flu outbreak) and 25 states are reporting widespread activity (a metric that captures the estimated level of spread of influenza activity through state and territorial epidemiologists reports.)

WOONSOCKET, R.I. — Despite an increase in flu activity, a recent CVS/pharmacy survey showed that 56% of respondents still had not received their flu shot, although 93% were aware that there already have been reported cases of the flu this season, the pharmacy retailer stated.

Flu activity steadily is increasing in the United States, with eight states now having reported widespread outbreaks of influenza cases, according CVS/pharmacy, which cited the most recent Centers for Disease Control and Prevention report.
