Due to an increase in dengue cases, Bacolodnons have reverted to the “4S” method.

BACOLOD CITY, Philippines – The City Health Office (CHO) in this city has urged citizens to practice the strengthened “4S” in the fight against dengue fever, citing a 57.5 percent increase in local cases from January to the first week of May this year.

According to data issued on Thursday by the city’s Epidemiological Surveillance Unit, 115 instances were reported in the first 18 weeks of this year, with four fatalities, compared to only 73 cases and two deaths in the same period in 2021.

Dr. Grace Tan, chief of the CHO Environment Sanitation Division, said the campaign to battle dengue fever is being sustained by urging barangays to practice the expanded “4S.”

“4S” stands for “Search and eliminate” mosquito breeding sites, “Secure self-protection measures” such as wearing long pants and long-sleeved shirts and using mosquito repellent on a daily basis, “Seek early consultation,” and “Support fogging/spraying.”

“We’re also launching a public address system and a tri-media campaign, as well as larvicides distribution and spraying and fogging in barangays and public places,” Tan said.

Dengue fever cases are more common during the rainy season, however, occurrences have been observed throughout the year.

The most common breeding areas for Aedes mosquitoes inside and outside homes are collected or stored water, while late or refusal to seek early treatment and consultation are causes why people become ill with dengue, according to Tan.

The top ten barangays in Bacolod with the most instances are Singcang-Airport and Estefania, with 14 each; Mansilingan and Granada, with ten each; Mandalagan, with nine; Sum-ag and Alijis, with eight each; Tangub, with seven; Banago, with five; and Pahanocoy, with four.

The dengue virus is spread by infected Aedes aegypti and Aedes albopictus mosquitoes that can be found both inside and outside the house, according to the Department of Health.

These mosquitos can lay eggs in any place or container that has clear, stagnant water, and they bite between the hours of sunrise and sunset.
