Because Guinea worm disease (GWD) can only be transmitted through drinking contaminated water, educating people to follow these simple control measures can completely prevent illness and eliminate transmission of the disease:
- Prevent persons with an open Guinea worm ulcer from entering ponds and wells used for drinking water.
- Always filter drinking water, using a household cloth filter or pipe filter, to remove the water fleas which harbor the infective Guinea worm larvae.
- Treat unsafe sources of drinking water with an approved larvicide, such as ABATE®, that kills water fleas.
- Provide communities with safe sources of drinking water (such as from borehole or hand-dug wells), or have existing dysfunctional ones repaired.
