Results of PCR testing of specimens from patients from New South Wales received at the VIDRL, Melbourne, Victoria, Australia, November 1, 2013–February 28, 2014 *

Test Specimens, no. (%) Patients, no. (%)
Total no. 420 (100) 308 (100)
PCR+ for HPeV 289 (69) 198 (64)
PCR+ for HPeV only 285 (68) 194 (63)
PCR+ for HPeV and EV† 4 (1) 4 (1)
PCR+ for EV only 15 (4) 14 (5)
PCR+ for EV 19 (5) 18 (6)
PCR− for HPeV 131 (31) 110 (36)
PCR− for HPeV and EV 116 (28) 96 (31)

*EV, enterovirus; HPeV, human parechovirus;VIDRL, Victorian Infectious Disease Reference Laboratory: +, positive; –, negative.
†Because of how the testing algorithm is set up at VIDRL, all samples tested for HPeV are also tested for EV. EV results are shown to demonstrate the small amount of EV detected in this HPeV outbreak period, with even fewer co-infections.
