This article assesses how the last-visit features and the socio-demographic profile of tourists moderate repeat-visit patterns to Portugal, a mature destination where the persistence of loyal visitors has made its mark on tourism development. The methodology used is a survival analysis to assess the tourists’ repeat patterns. To test the model, a database of 4612 observations was employed, which was obtained from a survey of international tourists. Only repeat visitors with more than two visits over the years were considered for the purpose of the research. The study finds that a combination of socio-demographic characteristics, expectation/satisfaction, trip purpose, pull motivations and regional destination has a positive effect on repeat patterns, confirming that tourists’ willingness to repeat visits to Portugal is far from ceasing. Based on those tourists to Portugal who declared when they started to visit the country, and the number of years of their repeat visits, the article contributes to the literature by introducing new methods of assessing tourists’ repeat patterns for destinations.

Understanding what characterizes patients who suffer great delays in diagnosis of pulmonary tuberculosis is of great importance when establishing screening strategies to better control TB. Greater delays in diagnosis imply a higher chance for susceptible individuals to become infected by a bacilliferous patient. A Structured Additive Regression model is attempted in this study in order to potentially contribute to a better characterization of bacilliferous prevalence in Portugal. The main findings suggest the existence of significant regional differences in Portugal, with the fact of being female and/or alcohol dependent contributing to an increased delay-time in diagnosis, while being dependent on intravenous drugs and/or being diagnosed with HIV are factors that increase the chance of an earlier diagnosis of pulmonary TB. A decrease in 2010 to 77% on treatment success in Portugal underlines the importance of conducting more research aimed at better TB control strategies.
