A total of 791 dengue cases were reported in 15 cities across China's Guangdong province, health authorities said Monday.
Chaozhou city has seen the highest number of cases, at 691, said the province's health and family planning commission.
A spokesperson from the commission said they were only seeing around 30 new cases a day, Xinhua news agency reported.
Dengue is a mosquito-borne, potentially fatal disease that mainly affects people in tropical and subtropical regions, causing fever and nausea, as well as muscle and joint aches.
Guangdong reported the majority of China's 46,000 dengue cases last year, including more than 35,000 in the provincial capital Guangzhou.
