Recent identification of the first variant H3N2 (H3N2v) cases linked to county fairs this summer prompted the US Centers for Disease Control and Prevention (CDC) to issue a Health Alert Network (HAN) advisory today to health providers that contains the latest information about testing patients and investigating outbreaks.
Officials in Indiana report that 8 people are newly infected with the H3N2v flu virus.
Last week's report of four variant H3N2 (H3N2v) influenza cases linked to a county fair in Indiana "may foreshadow a number of outbreaks this summer," like those last summer, the Centers for Disease Control and Prevention (CDC) said in a Jun 28 update statement.
Indiana officials reported four H3N2v infections in people who attended the same county fair.

(CIDRAP News) – With this year's big outbreak of swine-origin H3N2 influenza apparently over, a leading flu expert at the Centers for Disease Control and Prevention (CDC) says extensive contact with pigs seems to have been the key risk factor and that very few cases had clear signs of human-to-human transmission.
(CIDRAP News) – Researchers report that swine and human influenza A/H3N2 viruses associated with an Ohio county fair held in July make a nearly perfect genetic match, suggesting that there is almost no biological barrier to prevent such viruses from passing between humans and pigs.
