Groundbreaking research to enable rapid diagnosis of bird flu - including the deadly H5N1 strain which can be fatal if passed on to humans - is being developed with the help of Nottingham Trent University. Experts from the university's School of Science and Technology are playing a key role in a European project to create portable machines capable of identifying the disease instantly, potentially saving the lives of countless humans and animals.
The technology, which would be able to identify both human and animal influenza, would prove to be a vital tool in the fight against bird flu, making it possible to set up exclusion zones and cull infected birds much faster, before infection spreads. This preventative measure is seen as absolutely crucial as there is still no definitive vaccine to treat the virus.
Tens of millions of birds have died or been slaughtered as a result of bird flu, or avian influenza, in recent years. The disease - which is transmitted among birds and from birds to other animals through ingestion and inhalation - has spread across Asia, Europe, the Middle East and Africa. Although the H5N1 strain of the virus does not pass easily from birds to humans, it has so far claimed 243 lives from 385 confirmed cases.
Humans typically catch the virus by coming into contact with sick birds, but if a strain gained the ability to pass easily between humans the results could be catastrophic - with some experts predicting anything between two million and fifty million deaths worldwide.
The new tool would allow fast, on-the-spot screening of sick persons, distinguishing those carrying deadly strains from those subject to lesser flu variations, hence not requiring immediate total isolation.
Avian influenza occurs quickly with affected birds typically showing swelling of the head, blue discoloration of the neck and throat, dullness, a loss of appetite, respiratory distress, diarrhoea and a drop in egg production.
