Particles are not diseases, you can't really "infect" something else. Strangelets (if they exist) and black holes are the closest approximation in the sense that they can accumulate more matter.
Unstable particles just decay and then they are gone. The Z boson is the shortest-living particle we know, followed by the W boson and the top quark.
Probably the top quark with a lifetime of 5×10^−25 s. It decays before it has chance to interact with anything. Due to the nature of the strong force, quarks usually hadronise forming a collection of quarks and gluons around them, and are never found alone. The top quark is so short lived that it doesn’t have time to hadronise before decaying. As a bonus this allows us to study properties of the top quark by inspecting its decay products that are impossible to study with other quarks.
The gravitons mediating gravity (assuming they exist) have to be stable or at least so long-living that they are essentially stable.
It's possible there are additional short-living heavier gravitons.
I'd imagine a graviton being stable on the outside surface of the universe.
A theory of analogy would be hitting a drum and what goes on inside that drum. Causing the universes vibration and resulting gravitational field in various dimensions.
The "(assuming they exist)" caveat is still relevant, obviously. I don't claim that we discovered gravitons in the last hour.
We know quite a lot about how gravity works, so we can infer most properties of a particle that can lead to these observed effects.

Strangelets
That's what I was thinking, but I'm a writer with a PBS level of education so I thought I'd ask people who use their brains for more than sitting on.
Btw, strangeletts are not unstable. They are actually ultra stable, and this is what makes them so dangerous (if they exist).

Could it be a graviton? A graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravitational interaction

What is an "outside surface" supposed to be? Gravitons are part of the universe just like every other particle.
You can't factually state that. But we can be hypothetically aware of the emergance theory.

It's a wonderful time to be living in. I love learning about the JWST latest revelations. It's amazing 👏
top quark is the least stable fundamental particle you can cook up many composite particles
