A 15-year-old girl from Laos' Vientiane city has been suspected of contracting bird flu virus strain H5N1, the country's news agency KPL reported Monday.

Initial tests conducted in Thailand showed that the girl has been infected with bird flu virus strain H5, Laos Health Minister Ponmek Dalalay said. However, the case has not been confirmed yet.

The girl, who is now under bird flu test and treatment in Thailand, was admitted to a hospital in Vientiane on Feb. 15 with symptoms of headache, cough and fever.

According to the girl's family, she has no contact with dead poultry before falling ill.

Laos' health authorities are closely coordinating with their Thai counterparts to monitor the case, said the report.

Laos is taking concrete measures, including calling for help from international organizations in terms of technique and finance, to deal with the disease, which broke out among poultry in the capital city two weeks ago.
