Health officials around the world voiced fears during the winter that migratory birds that flew south to Africa last fall would spread the deadly virus into Europe during their return this spring.
The fact that hasn't occurred is a significant finding for Europe, since it's much simpler to monitor a virus on farms than in the wild, The New York Times reported Thursday.
In thousands of samples collected in Africa this winter, not one bird was found carry the avian virus, scientists told the newspaper.
The number of European bird flu cases has declined sharply since February, when dozens of new infections were reported daily. The last case was discovered April 28 in a grebe in Denmark, along with a falcon in Germany and a few swans in France, the Paris-based World Organization for Animal Health reported.
Many European nations responding to the good news are lifting restrictions intended to protect domestic poultry from infected wild birds.

'Deadly dozen' reports diseases worsened by climate change
Health experts from the Wildlife Conservation Society today released a report that lists 12 pathogens that could spread into new regions as a result of climate change, with potential impacts to both human and wildlife health and global economies. Called The Deadly Dozen: Wildlife Diseases in the Age of Climate Change, the new report provides examples of diseases that could spread as a result of changes in temperatures and precipitation levels. The best defense, according to the report's authors, is a good offense in the form of wildlife monitoring to detect how these diseases are moving so health professionals can learn and prepare to mitigate their impact.
How does bluetongue virus survive through the winter?
In 2006, Bluetongue virus – which infects livestock – reached Northern Europe for the first time. Some people thought that the outbreak would be limited to that particular year, as winter was expected to kill off the midges that host and spread the disease, bringing the threat of infection to an end. In actuality, the disease escalated in the following year, spreading to the UK. So, how did the virus survive the winter?

Towards understanding bluetongue outbreaks
A recent article published in
Virology, reports the identification of a bluetongue virus strain that caused the northern European Bluetongue outbreak in 2006. Comparison of the virus strain with the sequences of other previously isolated strains showed that it originated in sub-Saharan Africa, rather than from vaccine strains or strains circulating in southern Europe.
Midge-hunting scientists tackle spread of devastating bluetongue virus
Scientists at the BBSRC-funded Institute for Animal Health (IAH) are stepping up the battle against the devastating and economically damaging bluetongue virus. By combining ingenious ways to trap and monitor midges with cutting edge computer modelling and weather predictions the IAH team are gaining an understanding of how the insects spread the disease so that they can improve surveillance methods and advise farmers how and when to protect their animals.
