Taiwan confirmed another imported case of swine flu Monday, bringing to 13 the total number of individuals who have been infected with the influenza A(H1N1) virus in the country. The 13th patient was an 8-year-old Canadian girl of Asian descent who was sent to a local hospital for treatment and quarantine after arriving at Taiwan Taoyuan International Airport early Sunday, the Central Epidemics Command Centers (CECC) said in a statement. The girl showed flu symptoms, such as fever, coughing and vomiting, after arriving at the Vancouver airport May 29 from Montreal along with her parents. The family of three were bound for Cambodia via Taiwan. The girl's parents informed flight attendants of her health condition after boarding the plane in Vancouver, and the three wore face masks throughout the flight to Taiwan. Local quarantine officials conducted an on-board health check on the girl after the plane landed at the Taoyuan airport. The girl was then sent to Taoyuan General Hospital for treatment and quarantine. Laboratory tests confirmed Monday that the girl was infected with the H1N1 virus, making her the 13th confirmed swine flu patient detected in Taiwan. As the girl's mother also showed symptoms of coughing, she was also required to be tested, but it eventually confirmed she was free of the H1N1 virus, the CECC statement said. Based on an investigation into the girl's case, she likely contracted the virus in Montreal. As she and her parents all wore masks throughout the flight, local quarantine officials said individuals sitting near them had a low probability of contracting the disease. Thirty of the 54 passengers who were seated in the three rows in front of and behind the girl flew on to other destinations after a transit stop in Taiwan, the CECC said, adding that it has informed the World Health Organization (WHO) and other relevant countries of the case through the International Health Regulations-affiliated reporting system. The center has also notified Canada's representative office of the case, the statement said. As for the 24 passengers who have entered Taiwan, the statement said, they should contact local health bureaus or the epidemic center through the 1922 phone line to seek medical counseling if they develop flu-like symptoms in the coming week. Taiwan has so far recorded only one indigenous swine flu case and the remaining are all imported patients. Most of the confirmed patients have since recovered. As the country has not reported any new domestic infections since May 25, the epidemic center lowered the alert level to the second stage of yellow, which denotes that there are no community infections in Taiwan. As of 2 p.m. Friday, 53 countries had officially reported 15,510 cases of A(H1N1) infection, including 99 deaths, according to the latest World Health Organization report.
