Cases of flu sweeping across US; 170 hospitalized in Utah - December 30, 2013

SALT LAKE CITY ? Many Utahns are currently coughing, achy and weak. Flu season is in full swing, and doctors say within the past few weeks they've seen a spike in cases in Utah.

"We're seeing children with the flu, the elderly with the flu. People over 65 are at higher risk and children under the age of 2 are at higher risk of complications of the flu," said Adams Balls, Riverton Hospital Health.
..


"Nearly 10 percent of our adult cases were vaccinated prior to being hospitalized. Nearly half of our pediatric patients were vaccinated prior to being hospitalized," said Utah Department of Health representative, David Jackson.

At the WeekEnd, Atlanta

A December Void

During the minimal pH1N1 case count in the Northern Hemisphere's 2012 season and post-season, the US CDC demonstrated the experimental importance of Egg Passage strategies. Variant polymorphisms known to drive deep lung involvement in humans were surfaced repeatedly from quasi-species. That egg-based experimentation was considered valuable and was pursued throughout much of 2013, but evidently not to quantify the actual circulating pH1N1 viral population . . . because the production came to a full halt at the moment that the US flu season's high fatality rates became public due to an unexpected re-emergence of pH1N1 . . .

pH1N1
TamiFlu Resistance
in
Utah
​

A pH1N1 virus infecting a 14 year old female in late October 2013 exhibited TamiFlu Resistance in Utah.

100% of the Hemagglutinin amino acid polymorphisms on that AntiViral-Resistant sequence, Utah10_C1_14F_2013_10_29_TmX [EPI487732], appears on the most recently sampled Utah sequence from December 2013.

Deep Lung involvement and ARDS are expected based on the limited genetic superset of 9 pH1N1 sequences covering s2012, the inter-season (i2012) and the current season (s2013) for Utah.
