Abstract Stringent nonpharmaceutical interventions (NPIs) such as lockdowns and border closures are not currently recommended for pandemic influenza control. New Zealand used these NPIs to eliminate coronavirus disease 2019 during its first wave. Using multiple surveillance systems, we observed a parallel unprecedented reduction of other respiratory viral infections in 2020. This finding supports the use controlling severe threats.

Influenza disease burden varies by age and this has important public health implications. We compared the proportional distribution of different influenza virus types within strata using surveillance data from twenty-nine countries during 1999-2014 (N=358,796 cases). For each virus, we calculated a Relative Illness Ratio (defined as ratio percentage cases in an group to country population same group) for young children (0-4 years), older (5-17 adults (18-39 (40-64 elderly (65+ years). used...
Introduction Determining the optimal time to vaccinate is important for influenza vaccination programmes. Here, we assessed temporal characteristics of epidemics in Northern and Southern hemispheres tropics, discuss their implications Methods This was a retrospective analysis surveillance data between 2000 2014 from Global Influenza B Study database. The seasonal peak defined as week with most reported cases (overall, A, B) season. duration activity using maximum proportion during three...
Shiga toxin-producing Escherichia coli (STEC) O157:H7 and related non-O157 STEC strains are enteric pathogens of public health concern worldwide, causing life-threatening diseases. Cattle considered the principal hosts have been shown to be a source infection for both foodborne environmental outbreaks in humans. The aims this study were investigate risk factors associated with sporadic infections humans New Zealand provide epidemiological information about exposure pathways. During national...
Abstract How a history of influenza virus infections contributes to protection is not fully understood, but such might explain the contrasting age distributions cases two lineages B, B/Victoria and B/Yamagata. Fitting statistical model those using surveillance data from New Zealand, we found they could be explained by historical changes in lineage frequencies combined with cross-protection between strains same lineage. We additional against B/Yamagata people for whom it was their first B...
Neisseria meningitidis is the causative agent of invasive meningococcal disease (IMD), a form bacterial meningitis and septicaemia, leading to isolated cases, outbreaks, epidemics worldwide. Between 1991 2008, Aotearoa/New Zealand (NZ) experienced prolonged hyperendemic group B IMD outbreak caused by NZMenB epidemic strain, belonging clonal-complex 41/44 (cc41/44) identified PorA variant P1.7-2,4 (B:4:P1.7-2,4:cc41/44). continues account for approximately one-quarter cases in NZ. To...
New Zealand has a large reservoir of Mycobacterium bovis infection in wild and farmed animals. This study aimed to assess the extent human with this organism potential contribution these animal sources. Combined epidemiological laboratory investigation tuberculosis cases over period 1995-2002 showed that M. accounted for 2.7% (54/1997) laboratory-confirmed cases, rate 0.2/100,000 population. isolates from humans (23) were typed using restriction endonuclease analysis (REA) compared domestic...
One strain of Salmonella Brandenburg began causing large numbers human infections in New Zealand 1998. We investigated the emergence this using combined notification and laboratory data on animal disease a case-control study. S . infection humans was characterized by spring peaks high rates southern half South Island. This epidemic pattern followed very closely that seen sheep. The study found significantly associated with occupational contact sheep having household member who had sheep,...
We compared 2019 influenza seasonality and vaccine effectiveness (VE) in four southern hemisphere countries: Australia, Chile, New Zealand South Africa. Influenza seasons differed timing, duration, intensity predominant circulating viruses. VE estimates were also heterogeneous, with all-ages point ranging from 7–70% (I 2 : 33%) for A(H1N1)pdm09, 4–57% 49%) A(H3N2) 29–66% 0%) B. Caution should be applied when attempting to use data predict the northern season.

Data collected over winter 2009 by five World Health Organisation National Influenza Centres in the southern hemisphere were used to examine circulation of pandemic and seasonal influenza A strains during first wave hemisphere.There is compelling evidence that A(H1N1) virus significantly displaced and, a lesser extent, A(H3N2) viruses circulating hemisphere. Complete replacement strains, however, was not observed wave.
This paper uses data from multiple surveillance systems to describe the experience in New Zealand with second complete wave of pandemic influenza A(H1N1)2009 2010. Measures such as hospitalisation rates suggest overall impact 2010 was between half and two thirds that first 2009. There considerable regional sub-regional variation a tendency for higher activity areas experienced low Demographic characteristics were similar those 2009 highest seen children under age five years, indigenous Māori...
Background The national influenza surveillance in New Zealand is an essential public health component for assessing and implementing strategies to control influenza. Objective aim of this study report the data collected during 1997–2006 terms community disease burden, circulating viral strains, hospitalisations, mortality, immunisation coverage. Methods system includes sentinel general practice surveillance, laboratory‐based hospital admission mortality results obtained were analysed....
Abstract Genomic surveillance is an essential part of effective disease control, enabling identification emerging and expanding strains monitoring subsequent interventions. Whole-genome sequencing was used to analyze the genomic diversity all Neisseria meningitidis isolates submitted New Zealand Meningococcal Reference Laboratory during 2013–2018. Of 347 for whole-genome sequencing, we identified 68 sequence types belonging 18 clonal complexes (CC). The predominant CC CC41/44; next in...

OBJETIVO: analizar la estigmatización de los migrantes guatemaltecos retornados Estados Unidos Ameríca (EEUU) en primeros seis meses pandemia del COVID-19 Guatemala, y objetivos específicos fueron: a) Determinar situación retorno guatemaltecos. b) Analizar sus efectos psicológicos retornados. MÉTODO: este análisis requirió una revisión documental, aplicación entrevistas encuesta (en línea) dirigida a población guatemalteca RESULTADOS: se determinó que, sumó un estigma más al deportado: ser...
