Kong Tang, 35, walks past his apartment that has been flooded for over a week in Boeung Salang, Russey Keo, on Monday.

FLASH flooding caused by heavy rains has damaged more than 20 homes in Kampot province and sparked concerns about a spike in dengue fever in the capital, officials said Monday.

Ros Se, director of Kampot's provincial information department, said the province had been hit by five days of rain. Mao Hak, director of the national Department of Hydrology and River Works, said flooding had also occurred in Kratie, Stung Treng and Kampong Cham provinces.

Ngan Chantha, head of the National Anti-Dengue Programme, said the flooding made anti-dengue precautions more important, adding that 24 children had died of the disease this year.
