The source of infection was not established; but the reduced rainfall, associated with low, flat, flooded lands used for agriculture followed by animal grazing after harvest was probably related to the disease occurrence.

Outbreaks were numbered from 1 to 10 in chronologic order. The occurrence of tick fever on two farms in the same period that anthrax occurred made the diagnosis of the disease difficult. This situation appeared to be confirmed regarding Outbreak 7 where the farmer mentioned that the disease occurred more than 30 antarx ago, and after many years of vaccination this practice was abandoned.
