Diagnosis of Peripheral Facial Palsy Associated with Parvovirus B19 Infection by Polymerase Chain Reaction

Figure 1

Treatment with valacyclovir and prednisolone started on the second day of peripheral facial palsy. The erythema appeared approximately 3 weeks after peripheral facial palsy was first indicated. PVB19-specific serum IgM was positive and PVB19 DNA was detected in the serum by real-time quantitative PCR on the 26th day. Remission of erythema and peripheral facial palsy were confirmed on the 37th day and 54th day, respectively.
