Mass Deworming Administration Procedure (MDAP) Guide

Deworming is done semi-annually, in the presence of a health personnel, in coordination with DOH, and with parent’s consent. Providing the right information to your school community about deworming helps them to understand the value of the activity.

The goal of deworming a community is to eventually get rid of all the worms in the environment, this is why the Department of Health is giving away the medicine for free. The administration of the medicine for deworming is voluntary and will not be done without consent of a child's parent or guardian.

Recently it was reported allegedly that a student died and seven of her classmates were hospitalized after taking deworming tablets in their school.

To prevent Serious Adverse Events (SAES), Mass Deworming administration shall be done in accordance with the Mass Deworming Administration Procedure (MDAP) Guide.
