We recontacted members of our Wave 1 Community Advisory Boards as well as other community leaders and stakeholders to update them about our accomplishments and plans for redeploying in the city. We followed these efforts closely with a mail and telephone contact protocol in which we sent letters to participants about when and where we planned to deploy our MRVs in their neighborhoods. These letters invited participants to contact us for an appointment for their follow-up examinations. Two weeks after this mailing, the office-based track and trace staff phoned participants from whom we had not been contacted. When attempted contact by mail and phone were unsuccessful, we deployed our field-based track and trace staff. The field-based track and trace staff began by locating participants by using an intensive search engine, contacting listed next of kin, checking judiciary data bases, canvassing last known address, and visiting neighbors adjacent to last known address.
