In the U.S., Community Health Centers (CHCs) are neighborhood health centers generally serving Medically Underserved Areas (MUAs) which includes persons who are uninsured, underinsured, low-income or those living in areas where little access to primary health care is available. Largely federally and locally funded, some health clinics are modernized with new equipment and electronic medical records. In 2006, the National Association of Community Health Centers implemented a model for offering free, rapid HIV testing to all patients between the ages of 13 and 64 during routine primary medical and dental care visits.[11]
