A report this morning from Sohu.com (hat tip Treyfish on FluTrackers) that indicates that Tibet’s Naqu region has seen a new outbreak of highly pathogenic H5N1 among wild birds.

In recent years we haven’t often gotten reports of large wild bird die offs out of Asia, although they were fairly common four or five years ago.  

 

How much of this lull is due to lower levels of the virus in wild birds (or perhaps growing subclinical - asymptomatic spread), and how much may be attributed to limited surveillance and reporting is hard to know.

 

According to the FAO,  Naqu was the site of a significant die off of  birds ( approx 2,300 of mixed species), including 300 Bar-headed Geese (Anser indicus) back in 2006.

This machine translation indicates that while 170 dead birds have been discovered, no new bird deaths have been reported since May 25th.

 

A reminder that, while H5N1 has disappeared from the headlines, it still exists in the wild.  And as long as it does, it poses a potential threat.
