Turkish Prime Minister Tayyip Erdogan has said the bird flu crisis in his country is under control.
Mr Erdogan told a news conference that those who have tested positive are not at an advanced stage.
Local officials say the outbreak has infected 15 people and killed two, but a senior World Health Organisation official said it could be relatively easily controlled.
Two children from the same family from Dogubayazit in the east of the country died from bird flu - the first reported deaths from the virus outside China and southeast Asia. It is now thought a third child did not die from the same virus as her siblings.
Dr Guenael Rodier told journalists that the challenge facing health authorities was to maintain a high level of surveillance of both humans and poultry.
Another senior WHO official said genetic testing on samples from both human bird flu cases and poultry during the Turkish outbreak showed them to be very similar, supporting their initial conclusion that no mutation in the virus had yet taken place.
The H5N1 avian flu virus has so far killed over 70 people since re-emerging in east Asia in 2003. World health officials fear that if the virus changes to become easily passed on between humans, it could trigger a pandemic in which millions could die.
Turkey's government has come under criticism by worried Turks who have complained of a slow response to the outbreak, first spotted in poultry in October.
The Turkish authorities are considering imposing a total ban on the sale and breeding of poultry in open spaces. A temporary ban is in force in cities affected by bird flu.
H5 strain found in Crimea
Ukraine today found the H5 strain of bird flu at three poultry farms in eastern Crimea as the government battles an outbreak of the disease.
Mass poultry deaths were detected at the start of the month at three poultry plants in Primorskoe village in Crimea. Officials had initially denied the deaths were caused by bird flu but sent samples for tests.
Ukraine reported its first outbreak of bird flu in a dozen villages in Crimea, a major stopover point for migratory birds, in late November.
The Ukrainian Agriculture Ministry said a failure to maintain sanitary conditions caused the outbreak. Officials said they had destroyed about 98,400 birds at the poultry plants.
To the north in Romania, the virus has swept through domestic poultry flocks in dozens of villages around the Danube river delta although no human cases have emerged.
