Bangkok (VNA) - About 500 dengue fever cases have been recorded in northeastern Thailand by June 5, according to the Department of Disease Control under the Thai Ministry of Public Health.

The department’s report said that the 488 dengue fever cases were confirmed in four northeastern provinces, including Nakhon Ratchasima, Surin, Chaiyaphum and Buri Ram from January 1 to June 5.

Among them, Nakhon Ratchsima was the most active outbreak zone, with 233 cases diagnosed.

Adolescents aging 10 to 14 were found most prevalent with dengue infection, the Thai Office of Disease Prevention and Control said.

Officials visited the some high risk zones of dengue fever. They found many open water containers that allow the breeding of mosquitos.

Dengue fever is an infectious tropical virus transmitted to humans by the bite of female mosquitoes, which breed in clean, warm water.

More than 10,400 cases of dengue fever infection have been spotted in Thailand over the past five months with 15 deaths, reports said.

Thai authorities recommend citizens to clean their homes, find proper disposal of waste and garbage, and stow water receptacles away from where mosquitoes can breed.-VNA
