Prevention of guinea worm disease

(In this graphic, a man, while working in the fields, filters his drinking water.)

CONSIDERATIONS:

 

• The filter or filter cloth should be checked for holes before each use.
• The filter must be on the jar correctly to avoid contamination.
• The filter must be removed carefully to avoid accidental contamination.
• The filter and small jar must be taken to the fields everyday, or stored there permanently, so that they are readily available when the person becomes thirsty.
