Following the detection of imported cases of pandemic influenza A(H1N1)v on 25 April 2009, New Zealand implemented containment measures that appeared to slow establishment of the pandemic during May. The pandemic accelerated markedly in June, reaching a peak within four to six weeks, and has been declining since mid-July. By 23 August there had been 3,179(More)
New Zealand has a large reservoir of Mycobacterium bovis infection in wild and farmed animals. This study aimed to assess the extent of human infection with this organism and the potential contribution of these animal sources. Combined epidemiological and laboratory investigation of human tuberculosis cases over the period 1995-2002 showed that M. bovis(More)
Immigrant HIV infected Latinos, and those at highest risk for infection, demonstrate strikingly different patterns of risk behaviors and origins. This complicates the already complex acculturation process impacting their lives. By weaving together immigration and AIDS epidemiological patterns, the impact of tightening immigration policy, and masked sexual(More)

One strain of Salmonella Brandenburg began causing large numbers of human infections in New Zealand in 1998. We investigated the emergence of this strain using combined notification and laboratory data on human and animal disease and a case-control study. S. Brandenburg infection in humans was characterized by spring peaks and high rates in the southern(More)
This paper uses data from multiple surveillance systems to describe the experience in New Zealand with the second complete wave of pandemic influenza A(H1N1)2009 in 2010. Measures such as hospitalisation rates suggest the overall impact of influenza A(H1N1)2009 in 2010 was between half and two thirds that of the first wave in 2009. There was considerable(More)
BACKGROUND The national influenza surveillance in New Zealand is an essential public health component for assessing and implementing strategies to control influenza. OBJECTIVE The aim of this study is to report the national influenza surveillance data collected during 1997-2006 in terms of the community disease burden, circulating viral strains,(More)
UNLABELLED INTRODUCTION AND SETTING: Our analysis compares the most comprehensive epidemiologic and virologic surveillance data compiled to date for laboratory-confirmed H1N1pdm patients between 1 April 2009 - 31 January 2010 from five temperate countries in the Southern Hemisphere-Argentina, Australia, Chile, New Zealand, and South Africa. OBJECTIVE We(More)
INTRODUCTION Determining the optimal time to vaccinate is important for influenza vaccination programmes. Here, we assessed the temporal characteristics of influenza epidemics in the Northern and Southern hemispheres and in the tropics, and discuss their implications for vaccination programmes. METHODS This was a retrospective analysis of surveillance(More)
AIM We report the influenza activity in New Zealand in 2005 (including an influenza B epidemic) in terms of the disease burden, hospitalisations, viral strain characterisations, and vaccine recommendations. METHODS The national influenza surveillance system includes sentinel general practice surveillance, laboratory-based surveillance, and hospital(More)
