The Philippine health department said late on Thursday that there has been one A/H1N1 flu case confirmed in the Southeast Asian country.

The patient is a ten-year-old Filipino girl who arrived on May 18 from the United States, the Philippine Daily Inquirer reported, quoting Dr. Eric Tayag, director of the country's National Epidemiology Center. The patient had also visited Canada when she was in the United States.

Philippine Health Secretary Francisco Duque said the patient's specimen was tested positive based on results from the country's Research Institute for Tropical Medicine.

The patient is currently being treated at an undisclosed medical facility while her family were advised to follow quarantine and social distancing procedures from the Department of Health.

Health officials said the girl no longer has fever and cough but still has sore throat.

Despite the case, Duque said there is no community outbreak in the country.

"Measures are being done to prevent transmission including quarantine of immediate household of the first case. The first case is something we have been preparing for and a result of public and private sectors' effective surveillance system," he said.

Earlier on the day, the World Health Organization said that 41 countries had officially reported 11,034 cases of influenza A/H1N1infection, including 85 deaths.
