Cell parameters reflect variable designations used in Bayesian models outlined in Table 2 to estimate the unknown portions of cases (gray cells) that were either DA+, sporadic, or both.

This cell had very few cases in the FoodNet database. Since the proportion of cases assigned to this category was negligible compared to the other categories, and since these cases were likely misclassified, these cases were re-classified as sporadic, international travel-related (kti).
