It is a strange, strange agent.
It cannot divide and multiply.
It cannot self-replicate.
It is a parasite, a predator.
It has a shielding coat. It invades,
infects a host, sheds its cover,
and replicates itself ad infinitum
until the host weakens and succumbs.
It is invincible to medical treatment,
began eons ago in a garden lush
with mangos, figs, pineapples, coconuts.
The Agent infected a susceptible host.
This first host replicated in the other host.
Contagion carries in living hosts
in perpetuity, in all environments.
One physician has the cure.
