The Chinese rescue team had received 1,451 patients up to Monday night in the worst flood-hit district in south Pakistan, the team leader said on Tuesday.

Most patients are women and children, with skin diseases and diarrhea cases being the main problems, said Zhang Liyan.

The team groups 36 medical workers, and 19 rescuers and technicians. Fourteen female doctors were assaigned specially to offer medical aid for sick Pakistani women.

Currently, the medical group is receiving 600 patients each day, more than two times of the expected number, according to Zhang.

"The group will try its best to offer help to the Pakistan victims," he said.

The Chinese contingent is the first international rescue team arriving at Thatta, about 100 km northeast of Karachi. China has provided a total of 120 million yuan (17.7 million U.S. dollars) worth of humanitarian supplies to Pakistan in three batches.

The month-long devastating floods, the worst in Pakistan's history, have killed at least 1,600 people and affected over 20 million others.
