Single solutions continue to be inadequate in confronting the prevalent problems of poverty, ill health and insufficient health system capacity worldwide. The poor need access to an integrated set of financial and health services to have income security and better health. Over 3500 microfinance institutions (MFIs) provide microcredit and financial services to more than 155 million households worldwide. Conservative estimates indicate that at least 34 million of these households are very poor by the definition in the Millennium Development Goals, representing around 170 million people, many in remote areas beyond the reach of health agencies, both private and governmental. A small but increasing number of MFIs offer health-related services, such as education, clinical care, community health workers, health-financing and linkages to public and private health providers.
