The Massachusetts Department of Public Health (MDPH) Division of Global Populations and Infectious Disease Prevention has 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 will partner 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 will involve 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 will be used to develop surveillance interview questions and protocols, which will be pilot tested with community members and then refined into an implementation version. Throughout the project, ICH will help develop data collection tools, support recruitment, train MDPH staff on focus group and pilot interviewing techniques, analyze data, and collaborate with MDPH to interpret and apply findings. MDPH will use the results of this work to develop training materials for public health staff and infectious disease providers.
