As a first incidence of bid flu case in the capital of Zagreb it was revealed that a dead swan found there tested positive for the H5 strain of bird flu virus.

The location of the dead swan was on the shores of the Sava River in southeast Zagreb last weekend. Tests confirmed that the dead bird had contracted the H5 type of bird flu virus, but test findings as to whether it was the lethal H5N1 strain would be released on Sunday or Monday. This info was given by Mladen Pavic, spokesman for the Croatian agriculture, Forestry and Water Management Ministry.

In late February in 2006, the disease struck the country's southern coastal region, where two dead swans were tested positive for H5N1.
