To learn how outbreaks of infectious disease are detected and to describe the entities and information systems that together function to identify outbreaks in the U.S., the authors drew on multiple sources of information to create a description of existing surveillance systems and how they interact to detect outbreaks. The results of this analysis were summarized in a system diagram. The authors reviewed a sample of recent outbreaks to determine how they were detected, with reference to the system diagram. The de facto U.S. system for detection of outbreaks consists of five components: the clinical health care system, local/state health agencies, federal agencies, academic/professional organizations, and collaborating governmental organizations. Primary data collection occurs at the level of clinical health care systems and local health agencies. The review of a convenience sample of outbreaks showed that all five components of the system participated in aggregating, analyzing, and sharing data. The authors conclude that the current U.S. approach to detection of disease outbreaks is complex and involves many organizations interacting in a loosely coupled manner. State and local health departments and the health care system are major components in the detection of outbreaks.

African food was a connection to family and the African community. Food choices and activities were strongly influenced by accessibility, social structures, and the environment. Dietary and activity-based interventions should include both American and African influences.

Purpose The purpose of this study was to explore perceptions and attitudes around physical activity among immigrants from the Democratic Republic of Congo and examine the influence of Congolese cultural beliefs on physical activity practice. Methods In-depth interviews were conducted and augmented by photo-elicitation among 20 Congolese immigrants, distributed equally by gender, aged 35 years or older. The PEN-3 model was used as the cultural conceptual framework. Results Using both the Relationships and Expectations dimension (Perceptions, Enablers, and Nurturers) and Cultural Empowerment dimension (Positive, Existential, and Negative) of the PEN-3 model, emergent themes were categorized around knowing the benefits of being physically active (perceptions), doctor encouragement to be more physically active (enablers), and the habit and local tradition of consuming beer after a soccer match (nurturers). Other emergent themes included Congolese loves to dance (positive), going to the gym is not Congolese culture (existential), and the challenge of increased physical activity (negative). Conclusions Congolese have their intrinsic cultural perceptions and attitudes around types of physical activity. The study disclosed a much more pronounced willingness to dance (as a potential source of increased physical activity) than to go to a gym. As such, if one wants to advocate a regimen of increased physical activity to offset the risk for type 2 diabetes, dance is an alternative to consider among some immigrants.
