YUSHU, Qinghai - An emergency dispatch of 200 doses of rabies vaccine arrived in northwest China's quake-hit area on Tuesday, as more than 10 people have been bitten by Tibetan mastiffs, according to the health department of the rescue headquarters.

Many Tibetan mastiffs are homeless, as 90 percent of the houses collapsed in Gyegu town of the Tibet autonomous prefecture of Yushu in Qinghai province in the earthquake.

Seven or eight soldiers doing rescue work have been injured from mastiff bites, said a military medical official, surnamed Wang.
