Resumen

Se considera como enfermedades emergentes, en muchos casos reemergentes, a aquellas patologías infecciosas y no infecciosas que han aparecido en una población o que han existido en estado silente pero que están aumentando rápidamente en incidencia o rango geográfico. Factores diversos, como los cambios ambientales, adaptación de los microorganismos, se relacionan directa o indirectamente con el surgimiento y resurgimiento de nuevas entidades nosológicas.
