“The increase in dengue cases can be attributable to the El Niño phenomenon the country is experiencing,” Ona said, adding that continuous rains will also be responsible.

The health chief reminded the public that dengue, although an all-year round disease, is more common during rainy days when there are more potential breeding sites for the Aedes aegypti mosquitoes. To prevent dengue, Ona advised the public to destroy all mosquito breeding sites like old tires and tin cans, always clean roof gutters, replace water in flower vases regularly, use mosquito nets or protective clothing. He also stressed that fogging may be done only in outbreak areas.
