Delays in Patient Presentation and Diagnosis for Buruli Ulcer ( Infection) in Victoria, Australia, 2011-2017.

Uncertainty regarding transmission pathways and control measures makes prompt presentation and diagnosis for Buruli ulcer critical. To examine presentation and diagnosis delays in Victoria, Australia, we conducted a retrospective study of 703 cases notified between 2011 and 2017, classified as residing in an endemic (Mornington Peninsula; Bellarine Peninsula; South-east Bayside and Frankston) or non-endemic area. Overall median presentation delay was 30 days (IQR 14-60 days), with no significant change over the study period ( = 0.

Genetic divergence among members of the Kokobera group of flaviviruses supports their separation into distinct species.

The Kokobera virus group comprises mosquito-borne flaviviruses that cluster together phylogenetically. These viruses are unique to Australia and Papua New Guinea, and have been associated with a mild polyarticular disease in humans. Recent isolation of genetically diverse viruses within this group has prompted analysis of their genetic and phenotypic relationships.

Reduction in rotavirus-associated acute gastroenteritis following introduction of rotavirus vaccine into Australia's National Childhood vaccine schedule.

Introduction: : Rotavirus vaccines were introduced into the funded Australian National Immunization Program (NIP) in July 2007. Due to purchasing arrangements, individual states and territories chose either a 2-dose RV1 (Rotarix, GSK) regimen or 3-dose RV5 (Rotateq, Merck/CSL) regimen. This allowed comparison of both vaccines in similar populations with high infant vaccination coverage.

Pentavalent rotavirus vaccine and prevention of gastroenteritis hospitalizations in Australia.

Objective: A publicly funded, universal infant pentavalent rotavirus vaccine (RV5) program was implemented in Queensland, Australia, in mid-2007. We sought to assess vaccine effectiveness (VE) of 3 doses of RV5 at preventing rotavirus and nonrotavirus acute gastroenteritis (AGE) hospitalizations in the first birth cohort and impact on hospitalizations in all age groups.

Methods: Hospitalization rates for rotavirus and nonrotavirus AGE in all age groups before and after RV5 introduction were compared.
