Health officials said last week the onset of the rainy season can increase the risk of water-related diseases, but a dengue fever outbreak in Ratanakkiri province had been brought under control.
Dengue fever, a mosquito-borne illness that increases in the rainy season, was still a concern in at least six provinces, health officials said, and was on the rise in Kampong Cham, Kandal and Takeo provinces.
The monsoons, whose rains wash more chemicals and contagions into potential drinking water and create increased breeding ponds for mosquitoes, are a time of worry for disease experts.
