PRIORITIZED?

METHODS

Contact tracing: Malaria

Patients in 2014 in the village

INCLUSION

Slept in their permanent house within the village 14 days prior to onset of malaria

Signed a written consent form

Respondent ≥ 18 years old and above

Geo-reference for stratification (household level)

Knowledge, Aptitude and Practice Survey

Mosquito net ownership survey (and other vector control)

Household of the patient is a sampling unit

Children 2 – 9 years old (Prevalence survey)

Screen for malaria using RDT

Slept in their house 14 days prior to the visit

With parent’s/guardian’s consent

Geo-reference if () for hotspot analysis (ArcMap)

RESEARCH QUESTION

Is the use of hotspot analysis with malaria indicators surveys the appropriate GIS-based SDSS tool for foci investigations in relation to malaria elimination efforts in the Philippines?

OBJECTIVES

Assess the feasibility and need for GIS-based SDSS as a tool for malaria elimination of the Philippines

OBJECTIVES

• To collect information on the potential application of GIS-based SDSS for malaria foci investigations

• To serve as a basis for making applicable malaria foci

investigation tool that is specifically designed for malaria elimination.
