Is there as more positive sounding word to use in place of 'viral' or 'contagious', in regard to an idea or campaign?

Is there a there more positive sounding word to use in place of 'viral' or 'contagious', in regard to an idea or campaign?

The campaign relates to women's safety issues and sexual harassment.

We want the empowering message to be 'contagious', go 'viral', 'spread'.

All these words relate to sickness though. The campaign is one of social healing, so words like 'viral', and 'contagious' don't sound right. 'Spread' is better.

Any other suggestions?

The etymology of burgeon suggest new life:

early 14c., "grow, sprout, blossom,"
from Anglo-French burjuner, Old French borjoner "to bud, sprout,"
from borjon "a bud, shoot, pimple" (Modern French bourgeon), of uncertain origin.
Perhaps from Vulgar Latin *burrionem (nominative *burrio),
from Late Latin burra "flock of wool," itself of uncertain origin.
Some sources (Kitchin, Gamillscheg) say either the French word or the Vulgar Latin one is from Germanic.
The English verb is perhaps instead a native development from burjoin (n.) "a bud" (c.1300), from Old French.

Our campaign is burgeoning!
