I thought this was free verse, but there was a rhyming scheme. However, it's jarring that there's a rhyme, but no meter. I think if you used a meter, the whole poem would be more effective.
The subject matter is fairly intriguing. I interpreted it as being set in a future ravaged by disease rather than the past. Hope I got that right.
Thanks for pointing that out. I'm going to try to rewrite it using a meter and see how it goes. You're right, it is set in the future.
