PHNOM PENH, May 13 (Xinhua) -- Cambodia reported 2,277 dengue fever cases, killing 14 children in the first four months of 2012, Dr. Char Meng Chuor, director of the National Center for Parasitology, Entomology and Malaria Control, said Sunday.
During the four months this year, the infection cases of the disease had increased by 369 percent if compared to the same period last year, he said.
"It's a concern for us," he said, appealing to people to sleep in mosquito nets and keep clean environment around their houses.
"To prevent the disease, it's required to kill larvae by using Abate and by filling in puddles around houses, which are sources of mosquitoes," he said.
About 270 tones of Abate (a chemical substance used to kill larvae in water pots) will be distributed free of charge to households this year, he added.
Dengue is caused by mosquitoes. The disease causes an acute illness of sudden onset that usually follows symptoms such as headache, fever, exhaustion, severe muscle and joint pain, swollen glands and rash.
In Cambodia, the outbreak of dengue fever usually begins at the onset of the rainy season in May and lasts until October.
Last year, the country reported 15,980 dengue fever cases, killing 73 children.
