Agree, like any two living bodies, including humans, it's all about "chemistry"
The value of this statement lies in shifting the focus of the discussion from "labeling" to "understanding relationships." Whether a pathogen causes harm does not depend on its name or classification, nor on the health of the host, but on how the two meet and interact under specific conditions.

Virulence (harmfulness, clinical infection) is neither a property of the pathogen nor that of the host, it is a property of their interaction
Why do so many apparently healthy people die or get severely ill from infections that would be considered low risk?
For one, we don't have any way of assessing a person's immune system function in the clinic

Sosiego de confirmación
En cuestión de 10 minutos me he encontrado un hilo explicando que EEUU va a por el petróleo de Venezuela y otro analizando que NO va a por el petróleo de Venezuela.
Ambos hilos con razonamientos coherentes.
Es fascinante cómo en redes siempre encuentras el argumento que más te guste.

My declaration of the day:
Virulence (harmfulness, clinical infection), is neither a property of the microbe nor that of the host, rather it is a property of their interaction
Chemistry between two people is neither a function of person A or person B, but rather a function of their interaction
