DOST launches online dengue alert system ahead of rains


Aedes aegypti mosquito, carrier of the dengue virus

MANILA, Philippines—The Department of Science and Technology (DOST) will launch an online dengue alert before the start of the rainy season when cases of the deadly mosquito-borne hemorrhagic fever peak.

Through a dengue alert website, communities can regularly check the risk of a dengue outbreak in their areas based on the weekly monitoring of mosquito population densities to be conducted by all 45,000 public schools nationwide.

The bigger the estimated mosquito population in an area, the higher the possibility of being bitten by an Aedes aegypti mosquito, which transmits the deadly dengue virus, according to Science Secretary Mario Montejo.

The online dengue alert works like an early warning system so communities categorized as high-risk for a dengue outbreak can take early intervention measures to destroy mosquito breeding places.

The dengue virus-carrying Aedes aegypti mosquito prefers to hatch its eggs in clean, stagnant water and damp rough surfaces in dark areas.

The website was developed by the DOST’s research affiliate, Philippine Council for Health Research and Development (PCHRD).

Montejo said they will launch the nationwide dengue alert system ahead of the start of classes in June, when they would distribute ovicidal/larvicidal (OL) traps to all 45,000 public schools in the country.

Aside from serving as traps to kill mosquito eggs and larvae, the cheap commercially available OL trap kits can also serve to measure the mosquito density index in an area.

The weekly surveillance reports from dengue coordinators in the schools will be reflected in a monitoring map that will show those areas with high densities of mosquito population.

Once the mosquito density index in an area reaches the critical threshold, the community is alerted to take preventive measures.

The dengue alert will be color-coded: green for low, yellow for medium and red for high alert.

When 20 percent or less of the OL traps in an area are found to have mosquito eggs, a community is tagged with a green balloon, which calls for close monitoring and inspection of potential mosquito breeding sites.

A community with a mosquito density index of 20 to 39 percent gets a yellow alert balloon, which calls for special operations to eliminate all breeding and potential breeding places.

A red balloon means a mosquito density index of 40 percent or higher, which should alert the community to conduct pest-control measures.

Montejo said the mosquito density index is only one indicator of a possible dengue outbreak, as other indicators such as weather and dengue case histories must be included in the assessment.

He said the DOST developed the monitoring map project in collaboration with the Department of Education, Department of Health, Department of Interior and Local Government and local government units.

    Hindi nakayanan ng DOH ang Dengue last year. Aminado sila na wala silang laban…..

    Kalokohan kasi ng Aquino administration at mga corrupt na nabayaran ng mga pharmaceutical.

    Maraming namatay sa Dengue at maraming nagkasakit at nawalan ng pera at nabaon sa utang pambayad sa ospital. At the end of 2012, almost 1,000 patay…..140,000 nagkasakit…..

    Pero anong inuna ng DOH at pinaglaban ng husto????     RH at Condom para sa mga nangangati at di makatiis. Hindi dahils sa kagat ng lamok,….he-he-he.

    Ngayon humahanap sila ng budget para sa RH pero panlaban sa Dengue wala!!! 

    Basahin ninyo yung Inquirer balita last year…..”DOH fails to contain Dengue”

      The Department of Health (DOH) has failed to contain the spread of the dengue virus with the number of cases in the first month of the year already breaching the DOH’s projection of 80,000 dengue cases for the entire year.
      Based on the Dengue Surveillance Report, 80,745 Filipinos have been afflicted by the dengue virus from January 1 to August 18.
      DOH spokesperson Dr. Eric Tayag had earlier said they were looking to limit the number of dengue cases for 2012 to 80,000.
      “The cases last year was over 125,000. We targeted that this should not be more than 80,000 [this year],” Tayag said in July.
      The number of dengue cases from January to August 2012 is 14.14 percent higher compared to the 70,745 cases recorded in same period last year.
      Deaths from dengue also continue to rise from 424 last year to 496 this year.
      Most of the dengue cases reported were in the National Capital Region (NCR) with 16,087, followed by Central Luzon with 12,401 and Calabarzon with 11,839.
      A steep rise in dengue cases has been reported in Zamboanga Peninsula, from 883 to 2,825 (219 percent); Western Visayas, from 2,121 to 6,242 (194 percent); Davao Region, from 2,352 to 5,917 (151 percent); Northern Mindanao, from 1,316 to 3,248 (146 percent), and Bicol Region, from 835 to 1,926 (130 percent).
      More than half of dengue victims were male, said the report. About 40 percent of the dengue cases involved children aged between 1 to 10 years old, the DOH said.

       High time to push the “Google “Fabunan Antiviral Injection” CI4AM  on
      Facebook and “Dengue Killer” @ you tube and you will be amazed. DOH has
      suppressed this National Treasure for long long time. Spread the word
      and save lives for the virus are getting deadlier.

    if filipino people did not elect noynoy as president there will be no dengue today in our country…

    let’s blame aquino administration for this dengue virus…

    Worst part, the DOST Secretary knows about the existence of FAI “Fabunan Antiviral Injection”. Please Mr. Secretary, do your job and save your people.
