I have read this, and I read "and stamping out an epidemic that has killed more than 1,000 people and infected more than 40,000."
So, from Cambridge Dictionary I get:
stamp something out
— phrasal verb
to stop or destroy something:
After read the definition the text makes sense to me which is perfect but... if I isolate those words and look for "stamp" and "out" the text above does not make sense to me. So, I conclude that a phrasal verb is not linked with their isolated words. How is it possible? (I do not if I am right or not).
