In 2006, the introduction of a highly effective vaccine against human papillomavirus (HPV) exposed the need for population-based surveillance of HPV-related diseases. In 2007, the Centers for Disease Control and Prevention funded a collaboration between CEIP and the California Department of Public Health STD Control Branch to conduct surveillance of cervical pre-cancer including cervical intraepithelial neoplasia (CIN) 2/3 and adenocarcinoma in situ (AIS). This surveillance effort is ongoing in Alameda County, California in partnership with the Alameda County Department of Public Health.


  • Determine the burden of CIN 2/3 and AIS in Alameda County and monitor trends in incidence
  • Conduct HPV testing for a subset of cases to monitor HPV types
  • Monitor and evaluate the impact of the HPV vaccines
