Yunnan Province Reports Their 1st H7N9 Case (Imported)


One of the concerns going into this busy 5th winter epidemic of H7N9 in Mainland China was how this year's Lunar New Year Holiday - often called the Spring Festival travel season - would affect the spread of  diseases, including avian flu (see The CDC's Travel Advice For Lunar New Year's In Asia)..  
With hundreds of millions of trips planned over this 40 day period - often aboard crowded buses and trains - public health officials in China, and around the world, are on higher alert for the possibility of seeing imported cases.
While we don't have much data on this year's travel season, we do have the following report on an imported case in Yunnan Province - which had never reported an H7N9 case before - involving a child who visited Jiangxi Province over the New Year's holiday. 

According to Hong Kong's most recent Avian Influenza Report, Jiangxi Province has reported 19 H7N9 cases during this winter's epidemic.

The child, age 3, reportedly died on Feb 7th.  Close contacts are being monitored.

While it is becoming impractical to blog each and every H7N9 case report, particularly given the fragmented and belated way data is being released, when a new province is involved or a sizable number of cases (as in my last post) are revealed, I'll continue to try to provide updates.

The reality is, we are almost certainly only seeing the tip of the iceberg, and so numbers of cases reported should always be taken with a sizable grain of salt.
