The number of dengue fever cases recorded in Taiwan since May has increased to 5-thousand nine hundred forty eight, with about 90 percent in the southern city of Tainan.

The island's health authorities reported on Monday that a total of 5,247 cases were reported in Tainan. The neighboring Kaohsiung City has reported 609 cases, accounting for a little more than 10 percent.

Thirty dengue fever related deaths have been reported, 29 of which were in Tainan.

During an emergency meeting, experts have warned the situation might get out of control if the local government fails to put a halt to the fast spread of the disease.

October and November are the normal outbreak period for dengue fever.
