Correction to: Trop Med Health (2021) 49:70 https://doi.org/10.1186/s41182-021-00361-9

Following publication of the original article [1], the authors reported some errors in Tables 3 and 4 of the manuscript. The reference levels within Tables 3 and 4 should be 0 instead of 1. Cutoff points for vomiting episodes in Table 4 should be 1–4, 5–9, > 9. The reference level of sex should be female in Table 4, and the coefficient for male is 0.69.

The correct Tables 3 and 4 have been provided in this Correction.
