text: Yo, listen up, I got a story to tell,
  'Bout a virus that's got people goin' through hell.
  It's called Cytomegalovirus, CMV for short,
  Infectin' patients in the ICU, holdin' no support.
  
  Critically ill, immunocompetent, they feel the pain,
  Studies show CMV's got a deadly game.
  Increased mortality rates, that's the first sign,
  ICU stays and hospital length of time.
  
  Mechanical ventilation, they can't catch a break,
  CMV's got 'em sufferin', make no mistake.
  Nosocomial infections, it's a nasty spree,
  But is it really CMV causin' this misery?
  
  Some say it's just a marker, the illness is severe,
  Others claim CMV's the reason they're livin' in fear.
  Polymerase chain reaction, that's the test,
  Detectin' CMV, puttin' patients to the test.
  
  Antigenemia's another way to find the clue,
  Diagnosin' CMV, it's what they gotta do.
  Different organ systems, it can attack,
  CMV's got a variety, that's a fact.
  
  But treatin' CMV, it's a tough road to go,
  Diagnostic challenge, toxicity, yo, it's a blow.
  We need a predictive model, somethin' to rely,
  Identifyin' those at risk, so we can try.
  
  Prophylactic therapy, that's the goal,
  Preventin' CMV, keepin' patients whole.
  So let's review the literature, get the facts straight,
  Prevalence, incidence, clinical traits.
  
  Diagnostic modalities, their limitations too,
  Prognosis, therapeutic options, we gotta pursue.
  CMV disease in the critically ill, it's a fight,
  But with knowledge and research, we'll shed some light.
