The Department of Health (DOH) on Tuesday disclosed that the number of dengue cases in the first nine months of 2015 has increased to over 90,000.
Latest data from the Epidemiology Bureau (EB) showed that a total of 92,807 dengue cases nationwide was recorded from January 1 to September 19 this year, a 23.5-percent increase from that during the same period in 2014.
The data also showed a 17.8-percent increase in total from 78,808 cases from January 1 to September 5 this year.
Region IV-A and Region III ranked first with 15.2 percent, followed by the National Capital Region (NCR or Metro Manila) with 11.2 percent, Region X with 7 percent and Region XII with 6 percent.
The provinces of Cavite and Bulacan recently declared a state of calamity because of dengue outbreaks there.
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 a person is bitten by the female Aedes mosquito.
The DOH advises the public to maintain cleanliness in their surroundings and to properly store their water to prevent mosquitoes from creating breeding spots.
Its spokesman, Dr. Lyndon Lee Suy, recently said the situation does not call for the DOH declaring a state of calamity.
He added that the number of cases this year and in 2014 are still low compared to that in 2013, which had a total of over 100,000 cases from January 1 to September 19.
