A total of 102 cases of dengue fever have been reported in Dai Autonomous Prefecture of Xishuangbanna in southwest China's Yunnan Province since the disease was first discovered in the prefecture last Thursday.

They include four imported cases, according to the prefecture government's information office on Tuesday.

The prefecture government is asking local residents to kill mosquitoes to prevent the disease.

Dengue is a mosquito-borne, potentially fatal disease that affects between 50 and 100 million people in the tropics and subtropics each year, resulting in fever and muscle and joint aches.
