Via ProMED-mail, an edited post from the Texas Department of State Health Service: Influenza( 67): USA: (Texas) H1N1. But it's the moderator's comment that deserves attention:
The correspondent has added the following commentary in relation to the information above. "This outbreak now appears to involve an H1N1 virus. The vaccine inefficacy statement from the County health authorities press release highlights, coupled with the apparent unreliability of rapid diagnostic tests cited in media reports, suggests to me that H1N1 virus circulating in Texas may be a new [more virulent ?] drifted or reasserted strain. The current Texas state flu bulletin for week of 7-14 Dec 2013 issued today (20 Dec 2013) does not seem to discuss this issue http://www.dshs.state.tx.us/idcu/disease/influenza/surveillance/2014/."
On Saturday night, the DSHS link wasn't working, perhaps because it's overloaded. The moderator goes on to say:
It seems likely that the fatalities observed in Texas are due to a possibly more virulent strain of the seasonal H1N1 influenza virus, rather than a novel pathogenic agent. Further information is awaited to substantiate this conclusion.
