TECHNICAL GUIDELINES IN THE STRATIFICATION OF MALARIA ENDEMIC AREAS

A critical component of malaria control is the epidemiological assessment of malarious areas in order to document key local patterns of transmission and disease and to pinpoint priority areas for intervention. The experience gained in this type of stratification in other countries has increased the usefulness of the process in assisting malaria programs to establish operational priorities. A general sense of the focality and diversity of key variables is essential in order to determine the framework for rational stratification.

1.    DEFINITION

Stratification of the Malaria–Endemic Areas is the process of classifying the different endemic sites or localities of a particular barangay into type “A”, type “B” and type “MEPA” areas, endemic area being defined as having the malaria vector mosquito and the factors for transmission.

2.    OBJECTIVES

2.1  To establish operational priorities based on the defined criteria for stratification wherein malaria prevention and control measures will be appropriate and applicable.

2.2  To guide planners in resource allocation

3.    CRITERIA

3.1 Parasite rate of Children 10 years old and below

3.2 Terrain or Topography

3.3 Social, Economic and Cultural Conditions

4.    CHARACTERISTIC OF THE 3 TYPES BASED ON THE CRITERIA

CRITERIA	MALARIOUS A	MALARIOUS B	MALARIA EPIDEMIC–PRONE AREA (MEPA)
Parasite Rate	≥ 2% High transmission	≥ 2% High transmission	≥ 2% Low transmission
Topography	Mountainous Forested Generally Agriculturally less developed	Forest Fringes Foothills Agriculturally developed Plains Coastal	Any Topography
Socio–Economic Conditions	Houses poorly constructed Cultural Minority Seasonal Movement	More or less stable	More or less stable

5.    GUIDELINES

5.1 This be done and updated by the Field Assistance Worker (FAW) or the Municipal Malaria Coordinator (MMC) every three (3) years

5.2 The consolidate Provincial Stratification Data should be submitted to the Malaria Control Service (MCS) before the end of the 3^rd quarter of the year.

5.3 Table I illustrate the Stratification of Areas and the Appropriate Control Strategies to be implemented
