"Ill"ustrations in Iambics

My father's Uncle Titus 

has osteoarthritis.
The triplets -- Keir, Ken, Korey:

Doc's verdict...? "H. Pylori."

     My mother's Aunt Louise 

caught Legionnaire's disease.
With next-door neighbor Sidney, 

it's cancer of the kidney.
     My sister's in a coma 

with multiple myeloma.
A distant cousin -- Cyrus --  

contracted West Nile Virus.
     Some rabid rats gave rabies 

to Biddy and her babies.
And, though I feel like hell, 

I'm he who they call 'well.'
