The Ministry of Health Thursday reported it was closely monitoring the health of 35 passengers sharing the same flight with a woman who was later found with influenza A (H1N1) and quarantined in South Korea.

The Ho Chi Minh City Health Department also said Thursday that 11 of the passengers, who had earlier arrived at the city’s Tan Son Nhat International Airport, had tested negative for the virus.

These passengers had taken the flight OZ271 from the US to Vietnam. One of the passengers, Le Thi Bich, was quarantined for testing positive for the virus after the flight transited at the Incheon International Airport in South Korea. The 22-year-old woman is an overseas Vietnamese residing in the US.

Officials at the city’s Tan Son Nhat International Airport found and quarantined four passengers arriving with high temperatures, including a three-year-old child from Singapore and three Vietnamese citizens from Malaysia and Australia.

On the same day, health officials cleared two of them.

The Health Department of Ba RiaVung Tau Province on Thursday reported they have quarantined four people with high temperatures, including one returning from Indonesia and three workers of a petroleum company who returned from the US.
