Your symptoms indicate, Earth,
A humanoid infection.
Humans are pests,
Always present, usually harmless
Until their populations explode
Most often due to prolonged periods
Between ice ages.
A red line along the twilight
And an elevated temperature
Are dead giveaways.
It’s rare, but in the latter stages,
The disease is sometimes accompanied by brief but intense
Atomic flare ups.
There is no treatment,
But take heart,
The infection is usually not fatal.
The disease cannot live in its own waste
And most often turns upon itself.
You must simply let it run its course.
In just a little while you’ll be fine.
