But when you're dealing with an emerging, moving, dynamic target, which by definition is what a pandemic is, particularly if it's with a pathogen that you've never had experience with, like HIV in the very early 1980s, or the COVID-19 pandemic in the first months of 2020, you could always say, if we knew then what we know now, and there was a lot of things that we didn't know, we certainly would have done things differently.
Pero cuando lidias con un reto emergente, móvil, dinámico, lo que es la pandemia por definición, en particular si es con un patógeno con el que nunca has tenido experiencia, como VIH a los principios de 1980, o la pandemia de COVID-19, en los primeros meses de 2020, siempre podrías decir, si supiéramos lo que sabemos ahora, y había muchas cosas que no sabíamos, sin duda pudiéramos haber hecho cosas de manera diferente.
