Epidemiología de los coronavirus que afectan al ser humano

Abstract

Los coronavirus son virus que tienen su nicho natural en animales silvestres de diversas regiones del mundo, en especial murciélagos o aves, que albergan géneros específicos de estos virus: alfa y beta en murciélagos, y gama y delta en aves. En esos hospedadores definitivos el virus no causa enfermedad; es cuando dan el salto a otros animales silvestres o domésticos, incluso al ser humano, que se consideran hospedadores accidentales o intermediarios, cuando estos virus se pueden convertir, potencialmente, en causantes de enfermedad.
