We estimated the number of introductions using the phylodynamic model phybreak by integrating genomic and epidemiological data and inferred transmission events. By repeating this analysis with weekly cumulative case data, we assessed if introductions could have been reliably inferred in real time. The number of introductions, estimated after the outbreak ended, was 19 (95% CI: 13-29), and two larger transmission clusters existed. As these introductions occurred throughout the outbreak, we conclude that the Slovenian Mpox outbreak was mainly driven by new introductions. Analysing the data 'in real time' would have only slightly overestimated the number of introductions per week, capturing the trend of introductions as main driver of the outbreak.

In this study, we investigate the extent to which climate conditions modulate measles transmission, utilizing measles incidence data during 2005-2008 from China. Three climate-forced models were employed: a sinusoidal function, an absolute humidity (AH)-forced model, and an AH and temperature (AH/T)-forced model. These models were integrated into an inference framework consisting of a susceptible-exposed-infectious-recovered (SEIR) model and an iterated filter (IF2) to estimate epidemiological characteristics and assess climate influences on measles transmission. During the study period, measles epidemics peaked in spring in northern China and were more diverse in the south. Our analyses showed that the AH/T model better captured measles epidemic dynamics in northern China, suggesting a combined impact of humidity and temperature on measles transmission. Furthermore, we preliminarily examined the impact of other factors and found that population susceptibility and incidence rate were both positively correlated with migrant worker influx, suggesting that higher susceptibility among migrant workers may sustain measles transmission.
