I know that "onset" is a noun. I'm trying to find a verb to convey the onset of a disease. For instance, I need to make a list of things that are not covered by a medical insurance product, and one of the items is something like this:
- Congenital disease that <verb> or is confirmed by the insured before the age of 8
What verb would I put there to mean "onset"? Or how could I reword the phrase while keeping "congenital disease" as the focus of the phrase?
I've seen somebody write "Congenital disease that is infested or confirmed by the insured before the age of 8" and I find it a little weird. I can't find any supporting reference that says the verb "to infest" can be used this way.
I have had other people suggest "to contract", but that's definitely wrong because contraction is not the same as onset, and would not make sense for congenital diseases anyway.
