La respuesta correcta para esta pregunta abierta es la siguiente.
La situación y el método que se usó en el contagio bajo el concepto "guerra biológica" en la conquista de América fue cuando los Españoles - tanto exploradores como conquistadores- comenzaron a mezclarse con los nativos Mesoamericanos y los contagiaron de múltiples enfermedades que resultaron contagiosas y mortales ya que los nativos indígenas no eran inmunes puesto que esas enfermedades no existían en Mesoamérica.
Nos referimos a la viruela, la varicela, el cólera, la influenza, entre otras, que fueron traídas desde Europa por los Españoles, que no estaban a tener tanta higiene como los indígenas, que se sabe eran personas sumamente limpias y cuidadosas con su salud.
De ahí que esta serie de enfermedades tuvo un impacto devastador, ya que casi eliminó al setenta por ciento de población de indígenas Mesoamericanos. DE ahí que algunos historiadores consideren este impacto como el de una "guerra biológica."
