On Wednesday, Alameda County Supervisor Wilma Chan announced new efforts to expand health coverage to the estimated 13,000 county children who are eligible for publicly funded health coverage -- such as Medi-Cal, the state's Medicaid program, and Healthy Families, the state's Children's Health Insurance Program -- but are not yet enrolled. Among other efforts, Chan said the county will increase community outreach and begin using an online tool, called One-E-App, that allows families to electronically apply for health benefits.
