BANGKOK, May 30 (Xinhua) -- The Thai Public Health Ministry said on Saturday Thailand confirmed the third infected case of Influenza A/H1N1.
Dr. Prat Boonyawongvirot, the ministry's permanent secretary, was quoted by local newspaper The Nation's website as saying that a 50-year-old Thai woman tested positive for the flu after visiting the United States for 10 days with her family.
The woman, whose identity was kept confidential, developed high fever on May 24 while she was still in the United States. She arrived in Bangkok on May 26 and asked for medical treatment on the same day in a Bangkok hospital.
Prat said her samples were sent to test at the Siriraj and Chulalongkorn hospitals and the Department of Medical Science. The results of the lab test released on Saturday showed that she had the influenza.
Prat said the infected woman has now no flu but still coughs.
Passengers on her flight and her family were under observation as preventive measures, Prat said.
Thailand had its first two cases of the influenza earlier this month. They had already recovered.
