In medical literature the word
susceptibility collocates with negative adjectives or nouns -- negative prosody. Likewise, the word
predisposing factors or state is mostly associated with negative nouns: cancer, disease, and so forth.
I want similar words, but for a healthy condition or a healthy phenomenon that can take place in some individuals after acquiring certain infection, let's call this phenomenon
H. There is individual variation in displaying this healthy phenomenon.
so similar to below sentences, but in the context of health rather than disease:
Some individuals are more susceptible to develop H in their stomach.
Only subjects with a predisposing state will develop the H phenomenon.
These factors are most likely to be responsible for having the susceptibility to H in some individuals.
