The concern is getting bigger as new cases of dead birds are on the rise.

Hungary is the sixth EU country that confirmed an outbreak of the virus. Three dead swans were found in a southern county who had contracted H5 subtype and analyses are being performed at the moment to see if it were the H5N1 strain that can infect and kill people.

Among EU countries, dead birds were found in Greece, Italy, Ukraine, Romania and Germany but new cases are suspected in Austria and Slovenia. Other countries ordered their farmers to keep their poultry inside in order to prevent the spread of the virus.

Germany reported that two swans and a goshawk that were found dead in an island in the Baltic Sea had the H5N1 strain.

No matter all the preventive measures that are being taken, it seems that the risks can’t be reduced to zero. Health authorities are observing the spread of the virus in birds in case it mutates into a form easily transmitted among humans and sparks a pandemic.

Indonesia reports that they are experiencing a rise in the human cases of avian influenza.

Out of 169 people known to have been infected with the H5N1 strain since late 2003, 91 died, most of them being from Southeast Asia.

Different measures are being discussed about the possibility of detecting bird flu in commercial poultry.

Cases of dead swans in Denmark and Poland are being tested for the virus, however the Danes are hoping that it was a harsh winter rather than bird flu that killed them.

The EU is planning to prohibit imports of all untreated feathers to contain the spread of bird flu. Untreated feathers from six countries neighboring Turkey, including Syria and Iran have already been banned from entering EU.
