Answer

Other features of the rash are as follows:

  • The rash is often pruritic, especially in adults.

  • Enanthems are virtually never observed.

  • The rash is observed in approximately 75% of human parvovirus (PV) B19–infected pediatric patients but in less than 50% of infected adults.

  • The patient is no longer infectious when the rash appears
