Clarification

A statistical risk model based on the second wave of outbreaks in Thailand and a set of five environmental key factors maintained predictive power when extrapolated to Vietnam [3]. The same study supports such extrapolation to other countries with similar agro-ecological conditions. However, we recommend careful considerations concerning generalization of ecological studies involving different countries. Modeling ecological determinants require a sound analytical approach and local knowledge of the ecological factors.

I can only agree, and this is precisely why the Thailand and Vietnam model was evaluated against the South Asia situation in Gilbert et al. (2011; DOI: 10.1007/s10393-010-0672-8).

In another country, the Thailand and Vietnam model was also evaluated in Indonesia in Loth et al. (2011; Doi 10.1016/j.prevetmed.2011.06.006). and here too, the Thailand Vietnam model showed its limitations, most likely because of differences in farming systems.

So, I fully agree with the statement, but it would have been nice to consider these works in this last paragraph.
