Doctors in Taiwan say they are still trying to control the spread of a virus which attacks children under five.

At least thirty-three children have died of the virus since an outbreak in central areas of Taiwan a few weeks ago.

It is now spreading northwards to areas including the capital, Taipei.

A leading Taiwanese paediatrician Li Chin-yun warned that it could spread to other countries.

But specialists from the United States who are in Taiwan to help said it was too early to predict the movement and cause of the outbreak.
