Healthcare educator Rainelle White (R) talks to client Viola Sanon outside the Family Van in Boston, Massachusetts August 9, 2010. Every week, dozens of residents of this low-income Boston neighborhood stop into the Family Van, an RV manned by healthcare workers affiliated with Harvard Medical School who perform simple, free screenings, including blood pressure, body mass index and blood sugar, which can alert patients if they face an elevated risk for diabetes, hypertension or other chronic conditions.
