As far as I know, the "Día de los Muertos" is a big festivity only in Mexico (I do not know about the other Central American countries). In South America, it is not celebrated.
There was no tradition of Halloween in this part of the world, only in last decades its popularity has been increasing. Maybe, it is due to commercial and cultural influences.
