No it is not, it’s from exposure. The moment symptoms show you are already a walking dead man, even advanced options like ECMO don’t work.
I have had trouble finding an official source that agrees with that assessment. This source [0], for example, says it is from when symptoms show. Incubation period can be as long as a week.
