ANSWERS
Case 07 - Megan, 22 Years Old 

Megan is a 22 y/o with ALL, fever and vesicular rash. A lesion is unroofed and base is swabbed. PCR for VZV is + establishing the diagnosis of disseminated varicella-zoster infection.

Question:

What isolation precautions are indicated?

Answer:

This is one of a few situations where we need to utilize 2 of the transmission-based isolation precautions as varicella or disseminated zoster can be spread by both airborne and direct contact routes.

AIRBORNE + CONTACT

Only a few pathogens require use of AIRBORNE precautions:

  • Varicella/disseminated zoster (note - dermatomal zoster - no isolation generally needed as lesions can be covered and amount of virus present is magnitudes lower
  • Pulmonary tuberculosis
  • Certain types of influenza/other viral respiratory infection such as SARS
