Both Begin and End

Both begin and end
Infectious laughter attached
Viral reading trend

Haiku quarantined
Verse infected with laughter
Sides reported split

Other symptoms range
From feelings of "normalcy"
To life extension

Do not read haiku
Unless you like belly laughs
In small packages

If you find haiku
Do not panic, they smell fear
Call someone who cares

I don't know whether 
We can get out of this burb
Both begin and end

Infectious haiku 
Warning! Do not read this verse
Or the ones above
