My thanks to Crof who posted a media report (see Vietnam: A likely case of human H5N1) overnight on a gravely ill 5 y.o. girl from Phu Tho who is reportedly on a ventilator, and has tested positive for H5 influenza.

This is the first novel H5 influenza case reported from Vietnam since 2014.  During the first decade of the 21st century, Vietnam was a hot spot for H5N1, reporting well over 100 cases, before getting their avian flu situation under control.

For now, this virus is only identified as H5, which means it could be one of the many clades of H5N1, or possibly H5N6, or possibly even a new reassortment. We'll have to wait for the full analysis which could take days or even weeks. 

In the meantime we have the MOH announcement below.
