Pertussis AKA whooping cough is on the rise due to declining vaccination rates. The initial catarrhal phase has mild symptoms but is super contagious. Then you cough like forever.

Lyrics

[Chorus] cough cough cough hack
Whoop!
uh huh uh huh uh huh cough cough cough hack
Whoop!
uh huh uh huh uh huh cough cough cough hack

[Verse] Pertussis made a comeback
rapid spread, why the setback?
initial symptoms mild URI
super contagious that’s no lie
then you cough for evermore
a hundred days this much or more
Azithromycin treat with this
close contacts get prophylaxis
treatment only stops the spread
protect with vaccines use your head
