The Massachusetts Department of Public Health (MDPH) Division of Global Populations and Infectious Disease Prevention received funding from the Centers for Disease Control and Prevention (CDC) to improve surveillance capacity and reporting to better understand and document the risk of infectious diseases among globally mobile populations. ICH partnered with MDPH on a community engagement process to gather input on how to improve processes for collecting accurate mobility/travel histories from immigrant populations. This project involved key informant interviews and focus groups with people from India, China, Vietnam, and Haiti to explore topics such as travel patterns, concerns about reporting travel histories, trust in public health and medical personnel, and recommendations for data collection processes. Focus group and interview findings were used to develop surveillance interview questions and protocols, which were pilot tested with community members and then refined into an implementation version. ICH helped to develop data collection tools, support recruitment, train MDPH staff on focus group and pilot interviewing techniques, and analyze data, collaborating with MDPH to interpret and apply findings. MDPH used the results of this work to develop training materials for public health staff and infectious disease providers.
