Scientists worst fears have been confirmed. The strain of bird flu found in ducks in Romania is the deadliest type. Called by its scientific name, H5N1, it has already killed more than 60 people in Asia. The deadly strain of the virus has also been found in Turkey. Thousands of birds have been slaughtered in both countries in recent days to stop the virus from spreading. It is believed wild ducks carried the virus into Romania and bird flu has been found at two different locations in the country. Scientists concern is that this deadly strain of the flu could mutate and be passed on rapidly by humans. There is no evidence yet that anyone has been infected in Europe, but some scientists are warning it could be lethal and affect millions of people.
