The state Department of Health and several community-based sites today will offer free screenings for hepatitis B and C, in observance of World Hepatitis Day.

Call Aloha United Way's help line at 211 for a list of screening locations.

The health department's Immunization Branch estimates that 1 percent to 3 percent of people in Hawai'i have hepatitis B and that about 23,000 are living with hepatitis C. The agency said hepatitis B and C are the most common known causes of liver cancer in Hawai'i, and that Hawai'i has the highest rate of liver cancer in the United States.
