CDC confirms 2 new variant flu cases in Iowa
The Centers for Disease Control and Prevention (CDC) today confirmed two new variant flu cases in Iowa, according to its weekly Fluview update.
One case involves the influenza A H3N2 variant (H3N2v) and the other the influenza A H1N2 variant (H1N2v). Both infections are in children. Neither was hospitalized, and both have fully recovered, the CDC said.
Household members of one of the patients kept or cared for swine, while the other child had direct contact with swine. No human-to-human transmission has been associated with either case.
The CDC said, “When an influenza virus that normally circulates in swine (but not people) is detected in a person, it is called a ‘variant influenza virus.’ “
So far this year the CDC has recorded 9 variant flu cases, 2 of which were H3N2v, 2 H1N2v, and 5 H1N1v. Five cases have involved children, and four involved adults, all with direct or indirect contact with swine. No instances of human-to-human spread have occurred.

H5N8 avian flu outbreaks reported in Europe, Pakistan
France has reported highly pathogenic H5N8 avian flu in poultry in the northeast of the country, following similar outbreaks in Belgium and Luxembourg.
Ducks, hens, turkeys and pigeons at a household in the Ardennes region of France were all slaughtered after detection of H5N8, Reuters reported.
Earlier this week, Luxembourg had reported its first detection of high-path H5N8 in wild birds at a backyard facility after the introduction of new animals, according to a World Organization for Animal Health (OIE) report. In that outbreak, which began on Sep 2, 14 of 60 birds died, and the rest were culled to prevent further disease spread.
According to Reuters, the French farm ministry said, “The health situation regarding highly pathogenic avian influenza is worrying. Since Aug. 1, 25 cases have been detected in Europe among wild and captive birds.”
Last winter France had to cull 3 million birds in its duck-breeding region after wild birds spread H5N8 to poultry flocks, among other factors.
In Pakistan, an outbreak of H5N8 was reported in poultry at a farm in Punjab province. The virus killed all 3,000 birds at the facility, according to the OIE. That outbreak began on Aug 4.
