| Note: Population A included households with pregnant women and caregivers of young children surveyed in November 2011, approximately 6 months after LifeStraw® filters were distributed. Population B included households with pregnant women surveyed in November 2012, approximately 18 months after LifeStraw® filters were distributed. Population C included households with pregnant women surveyed June 2013–May 2014, approximately 24–36 months after LifeStraw® filters were distributed. aDirect observation by field staff. | |||
