Health advisory on dengue

Dengue cases are normally more prevalent during the rainy season. Thus, greater vigilance should be practiced to minimize the incidence of this disease. Everyone is advised to take measures to protect themselves against dengue-carrying mosquitoes.

  • The dengue virus is contracted from the bite of an Aedes aegypti (or less commonly Aedes albopictus) mosquito that has previously bitten an infected person (person-to-mosquito-to-another-person).
  • The incubation period (the time interval between exposure to an infection and the appearance of the first symptoms) is 3-15 days (usually 5-8 days) while the period of communicability (the time during which the dengue virus can be transmitted directly from an infected person to the mosquito vector) is usually 3–5 days (from shortly before the febrile period to its end).
  • Fever (usually high-grade, 40 degrees centigrade) and chills
  • Headache, backache and other body pains
  • Rash (flushed or reddish or pale pink in color)
  • If you or a family member has a fever of 2 days duration and rashes on the skin, consult a physician or visit the nearest clinic/health center/hospital immediately.
  • Report suspected cases of dengue to the University Clinic (call 637-0912 loc. 252 or email /
  • If you have been recently infected by dengue, get a medical clearance from the University Clinic before resuming classes or work.
  • Wear long-sleeved shirts, long pants, socks and closed shoes to avoid mosquito bites, especially at dusk and dawn.
  • Use safe mosquito repellents on your clothing and exposed skin.
  • Use anti-mosquito nets.
  • Spray insecticides under tables and behind curtains.
  • Throw away, turn over or empty any containers and old tires that may accumulate rain water.
  • Clean and change the water in flower vases every week.
  • Always place a tight lid on containers used for water storage (e.g. drums, buckets).
  • Check that there are no mosquito larvae or “kiti-kiti” in stored water.
  • Avoid having plants that could accumulate rain water.
  • Use screens on doors and windows.
  • Conduct mosquito fogging only during outbreaks. Fogging operations usually fail because they merely drive mosquitoes away to other areas.
  • Get vaccinated. Dengvaxia, a product of Sanofi Pasteur, is the first dengue vaccine approved by the World Health Organization. The vaccine is given in three injections spaced out over one year to persons 9-45 years of age. Please consult your physician for more information about the vaccine.
To help safeguard the UA&P community against dengue and other mosquito-borne diseases, the University, under the direction of Architect Raymund Go, Campus Maintenance and Planning Manager, continues to implement the following year-round pest control measures:
  • Regular mosquito misting around the UA&P campus, including the University Residence Hall construction area
  • Pouring of hot water on drains with stagnant water (i.e. floor drains, culverts, etc.), done twice a week
  • Deployment of electronic mosquito killer lanterns in strategic locations
In addition, the followings steps have been taken:
  • Removal of plants (i.e. bromeliads, etc.) that accumulate water
  • Supporting and sponsoring the “Adopt-an-Estero” program by the DENR to do clean-ups at the nearby creek
