A swan found dead at Dresden Zoo in eastern Germany was infected with H5N1 bird flu virus, German media reported on Friday.

The Saxon state health ministry said all the birds at the zoo had been confined as a precaution.

The new case was the first in Germany since April, when the virus was detected among domestic poultry.

In February, Germany witnessed an outbreak of bird flu among wild birds.

In June, the German parliament extended to next February a lock-up order for domestic poultry in those areas with a high risk of bird flu.
