Varicella zoster virus Sequence analysis of 342 clinical varicella and zoster specimens from 18 European countries identified the following distribution of VZV genotypes: E1, 221 (65%); E2, 87 (25%); M1, 20 (6%); M2, 3 (1%); M4, 11 (3%). No M3 or J strains were observed. Of 165 clinical varicella and zoster isolates from Australia and New Zealand typed using this approach, 67 of 127 eastern Australian isolates were E1, 30 were E2, 16 were J, 10 were M1, and 4 were M2; 25 of 38 New Zealand isolates were E1, 8 were E2, and 5 were M1.

International Society for Disease Surveillance biosurveillance. Every year, the ISDS conference draws over 350 professionals from a broad range of disciplines to learn the latest achievements, analytic methods, best practices, conceptual frameworks, and technical innovations in the rapidly evolving field of disease surveillance. The ISDS conferences provide fertile ground for cultivating new ideas and partnerships by bringing together local, state, and federal public health practitioners, academic researchers, clinicians, policymakers, and decision makers from governmental and nongovernmental entities. The 12th annual conference was held in December 2013, in New Orleans, LA. The theme for the 2013 conference—Translating Research and Surveillance into Action—highlighted one of the salient
