Patients with classic erythema infectiosum are no longer contagious after the rash has appeared. [9]

Patients with aplastic crisis, papular-purpuric "gloves and socks" syndrome (PPGSS), or immunosuppression and chronic parvovirus B19 infection with anemia should be isolated with droplet and standard precautions due to ongoing viremia. [9]

Maintain precaution for patients with TAC for 7 days or until the reticulocyte count rebounds to at least 2%, whereas those with chronic infection should be isolated for the duration of their stay. [9]

Pregnant staff should be alerted to the potential risks of parvovirus B19 infection when caring for these patients. [9]
