A Hong Kong woman who was injured in the explosion at a concert in Taiwan's New Taipei City on Saturday was transferred to a hospital in Shanghai for treatment on Tuesday.

The 18-year-old sustained burns to 37 percent of her body in the incident, in which theatrical colored powder ejected from a stage ignited and sent fire raining down on spectators.

The woman's parents, who live in Shanghai, applied to authorities there to help transfer her to the eastern city for treatment.

She is now being treated at Shanghai Ruijin Hospital.

The head of its burns and plastic surgery department said most of the patient's injuries are on her limbs. She is in a stable condition and will soon receive a skin-graft operation.

A total of 498 people were injured at the concert, staged at a water park in New Taipei. One of them, a 20-year-old woman surnamed Lee, died in hospital on Monday.

Among the injured are two students from the Chinese mainland, five from Hong Kong and six foreigners.
