 **Estimating epidemiological delays is CHALLENGING!**
 
-Epidemiological delays need to account for biases like censoring, right truncation, or epidemic phase ([Charniga et al., 2024](https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1012520)).

 Additionally, at the beginning of an outbreak, limited data or resources exist to perform this during a real-time analysis. Until we have more appropriate data for the specific disease and region of the ongoing outbreak, we can **reuse delays from past outbreaks** from the same pathogens or close in its phylogeny, independent of the area of origin.
