Cases of bird flu have been reported in different regions of Egypt, the first such cases in the country, as a world health official confirmed the existence of the H5N1 strain in the dead birds on Friday.
Some cases of bird flu appeared in different regions in Egypt, according to the Egyptian state-run Nile TV.
Meanwhile, the official Arabic Nile News TV reported that about 18 dead birds had been tested positive for avian flu.
The positive samples were from dead birds found in the capital Cairo, Giza, Menya and Qena, the report added.
Xinhua correspondents on Friday saw dead birds floating on the Nile river in Cairo's southern district of Maadi.
A senior official from the World Health Organization (WHO) confirmed to the media that tests had found the deadly H5N1 bird flu virus in the dead birds.
Hassan el Bushra, regional adviser for emerging diseases in the eastern Mediterranean regional office of the WHO, said that there was an outbreak of avian flu in Egypt.
The deadly H5N1 virus has killed 91 people worldwide since 2003, according to the WHO.
Most victims were infected after close contact with sick birds.
Scientists fear H5N1 could mutate into a form which could easily pass among humans and thus spark a global human flu pandemic.
