Dengue cases nationwide have reached the 100,000-mark in the first ten months of 2015, according to the Department of Health (DOH).
Latest data from the DOH-Epidemiology Bureau showed that a total of 108,263 cases was recorded from January 1 to October 3 this year, a 31.9-percent increase from the same period in 2014 with 82,049 cases.
Region III ranked first with 16.3 percent, followed by Region IV-A with 16 percent, National Capital Region (NCR or Metro Manila) with 12.1 percent, Region I with 8.5 percent and Region X with 6.2 percent.
Dengue fever and dengue hemorrhagic fever, as defined by DOH, are caused by any of the four serotypes of dengue virus (types 1, 2, 3 and 4) transmitted when bitten by the female Aedes mosquito.
DOH has advised the public to bring patients to the hospital if their fever persists for two or more days, and to continuously rehydrate the patients if they are diagnosed with dengue.
It said it is also important to maintain cleanliness and to properly store water supplies to prevent mosquitoes from creating breeding spots.
