This may be the first indigenous recording of massive outbreak within the country, said health officials.

Shih Wen-yi, a spokesperson for the CECC, said that health authorities are still in the process of determining whether or not the virus was imported from another country or indigenous to Taiwan and transmitted amongst the students.

This put the total tally of confirmed A(H1N1) cases in the country at 68, according to officials.

These seven adolescents, between the ages of 10 to 20 and consisting of four males and three females, arrived Taiwan, June 21 and displayed flu-like symptoms on June 25, said Shih.

The seven teenagers of ethnic Chinese descent were in Taiwan to study Mandarin, added local media.

In related news, Shih remarked that the Department of Health will begin procurement bidding on July 3 for the 5 million vaccines required by this fall. Health authorities promise at least one inoculation shot for those in the high-risk group such as children and the elderly.
