As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Scientists Complete First Global Inventory Of Flu Strains In Birds

A group of international scientists have completed the first global inventory of flu strains in birds by reviewing more than 50 published studies and genetic data, providing new insight into the drivers of viral diversity and the emergence of disease that can ultimately impact human health and livelihoods.
The research, published in the journal PLOS ONE and performed as part of the USAID PREDICT project, identified over 116 avian flu strains in wild birds. This is roughly twice the number that were found in domestic birds, and more than ten times the number found in humans. Additionally, an analysis of studies that sampled more than 5,000 birds suggested some regions may have more viral diversity than others.
Avian flu outbreaks come with no warning. In 2013, an H7N9 avian flu strain caused a deadly outbreak in people in China. This surprised virologists, as the strain had never before caused disease in humans. To date, there have been more than 300 clinical cases of H7N9 with a 33 percent mortality rate. This year, another strain known to infect birds, H10N8, has caused human cases for the first time.
