Invasive meningococcal disease--improving management through structured review of cases in the Hunter New England area, Australia.

Introduction: Invasive meningococcal disease (IMD) is the most common infectious cause of death in childhood in developed countries. This disease may cause severe disability or death if a patient is sub-optimally managed. An audit was performed in Australia of all 2005-06 notified IMD cases to elicit correctable issues.

Egg-associated Salmonella outbreak in an aged care facility, New South Wales, 2008.

Salmonellosis is a bacterial disease that causes acute gastroenteritis, with sudden onset of headache, abdominal pain, diarrhoea, nausea and sometimes vomiting. Infection is often associated with the consumption of foods prepared using raw eggs. During July to August 2008 an outbreak at an aged care facility (ACF) in New South Wales was confirmed as Salmonella Typhimurium phage type 44 (Stm 44) in eight of 45 residents.

Enhanced Q fever risk exposure surveillance may permit better informed vaccination policy.

The association between farming risks and Q fever is not well documented in Australia. In a review of New South Wales notifications, data were analysed using 3-year study periods from 1993 to 2007 to investigate possible trends and explore reported risk exposures. A retrospective case series was also conducted using acute Q fever cases notified during 2007 from a rural area of New South Wales.

Outbreak of human metapneumovirus infection in a residential aged care facility.

Summer outbreaks of respiratory illness in residential aged care facilities are uncommonly reported in New South Wales. A respiratory illness outbreak in an aged care facility during January 2008 prompted a response to contain the outbreak by implementing infection control measures, including cohorting of symptomatic residents, cohorting nursing care, closure to new admissions and the use of personal protective equipment by staff. In addition, respiratory tract specimens were collected to determine the causative agent.

Lessons from the Pacific programme to eliminate lymphatic filariasis: a case study of 5 countries.

Background: Lymphatic Filariasis (LF) is an important Neglected Tropical Disease, being a major cause of disability worldwide. The Global Programme to Eliminate Lymphatic Filariasis aims to eliminate LF as a public health problem by the year 2020, primarily through repeated Mass Drug Administration (MDA). The Pacific region programme commenced in 1999.

Using the SaTScan method to detect local malaria clusters for guiding malaria control programmes.

Background: Mpumalanga Province, South Africa is a low malaria transmission area that is subject to malaria epidemics. SaTScan methodology was used by the malaria control programme to detect local malaria clusters to assist disease control planning. The third season for case cluster identification overlapped with the first season of implementing an outbreak identification and response system in the area.

Ensuring safe drinking water in regional NSW: the role of regulation.

In regional and rural areas of NSW, drinking water is provided by 107 local water utilities serving a total population of some 1.7 million and operating 323 water supply systems. NSW Health exercises public health oversight of these regional water utilities through the NSW Health Drinking Water Monitoring Program, which provides guidance to water utilities on implementing elements of the Australian Drinking Water Guidelines 2004, including drinking water monitoring.

Is there a risk of malaria transmission in NSW?

NSW has a putative malaria vector in Anopheles annulipes, and increased numbers of immigrants from malaria endemic countries who may be infective to mosquitoes but asymptomatic. We examine the factors known to influence malaria transmission and conclude that local transmission is possible but unlikely. The public health implications are that there should be systematic screening of immigrants from malaria endemic countries on arrival, and that the public health capacity to identify and respond to a malaria outbreak should be maintained.

Identifying pneumonia outbreaks of public health importance: can emergency department data assist in earlier identification?

Objective: To retrospectively review the performance of a near real-time Emergency Department (ED) Syndromic Surveillance System operating in New South Wales for identifying pneumonia outbreaks of public health importance.

Methods: Retrospective data was obtained from the NSW Emergency Department data collection for a rural hospital that has experienced a cluster of pneumonia diagnoses among teenage males in August 2006. ED standard reports were examined for signals in the overall count for each respiratory syndrome, and for elevated counts in individual subgroups including; age, sex and admission to hospital status.

Barmah Forest virus serology; implications for diagnosis and public health action.

Barmah Forest virus (BFV) is a commonly occurring arbovirus in Australia. Notifications of Barmah Forest infections diagnosed by a single positive IgM serology test have been increasing in coastal New South Wales north of Newcastle. We report on a 6 month prospective review of all routine notifications of BFV from the Lower Mid North Coast of New South Wales.

Likely impact of school and childcare closures on public health workforce during an influenza pandemic: a survey.

During an influenza pandemic, public health staff may not report to work due to illness, transport disruptions or care responsibilities, including care of children if school closures occur. A survey was conducted in a population health unit to estimate the impact of closure of schools and day care facilities on staff ability to work at their usual workplace or at home, and determine their access to the Internet for communication. Staff were also asked about concerns associated with working from home.

Improving communicable disease outbreak preparedness in residential aged care facilities using an interventional interview strategy.

Objective: To improve the capacity of residential aged care facilities (RACFs) to respond to communicable disease outbreaks.

Methods: Three computer-assisted telephone interviews were conducted with RACFs. The first survey gathered baseline information.

Documenting the development of social capital in a community Safety Promotion Network: it's not what you know but who you know.

Issue Addressed: The Mackay Whitsunday Safe Communities (MWSC) was established in February 2000 in response to high rates of injury observed in the region. A key objective was to consolidate and better coordinate a network of community groups already working in community safety promotion.

Methods: This study used Social Network Analysis (SNA) to document and analyse the social resources, or social capital, mobilised by the network.

Australian Bat Lyssavirus: examination of post-exposure treatment in NSW.

Ten years after the recognition of Australian Bat Lyssavirus, it is timely to review the occurrence of the virus in native microbat and flying fox species in Australia, and the effectiveness of post-exposure treatment in humans. Differences between post-exposure treatment protocols adopted by state and territory health departments were examined. In Queensland and the United States of America, post-exposure treatment is withheld in people who are bitten by bats that subsequently test negative for ABLV and rabies, respectively.

Aboriginal and Torres Strait Islander peoples at higher risk of invasive meningococcal disease in NSW.

Objective: To assess the completeness of data describing Aboriginal and Torres Strait Islander status in NSW invasive meningococcal disease notifications and determine the relative risk for invasive meningococcal disease among Aboriginal and Torres Strait Islander peoples in NSW.

Methods: Surveillance data from the NSW Notifiable Diseases Database was reviewed for 5-year periods between 1991 and 2005.

Results: Invalid and missing data on Aboriginal and Torres Strait Islander status decreased from 42% to 8% during the study period.

Diagnosing childhood tuberculosis in rural clinics in Mpumalanga Province, South Africa.

Background: Tuberculosis is a major global public health challenge and disease in young children is particularly severe. Diagnosing tuberculosis in children is complex as clinical presentation is often atypical and available diagnostic modalities are imperfect. Diagnosis is particularly challenging in developing countries where resources and access to sophisticated facilities are limited.

A case-control study conducted in three affected jurisdictions, New South Wales, Victoria and Australian Capital Territory, included 36 cases with the outbreak-specific strain of S. Saintpaul identified by multiple locus variable-number tandem repeat analysis (MLVA) in a faecal specimen and 106 controls.

Household disaster preparedness and information sources: Rapid cluster survey after a storm in New South Wales, Australia.

Background: A storm-related disaster in New South Wales, Australia in June 2007 caused infrastructure damage, interrupted essential services, and presented major public health risks. We investigated household disaster preparedness and information sources used before and during the disaster.

Methods: Rapid cluster survey of 320 randomly selected households in Newcastle and Lake Macquarie, New South Wales, Australia.

The public health value of emergency department syndromic surveillance following a natural disaster.

During a recent natural disaster public health staff required timely and comprehensive surveillance of priority health conditions, including injury, mental health disorders and selected infectious diseases, to inform response and recovery activities. Although traditional surveillance is of value in such settings it is constrained by a focus on notifiable conditions and delays in reporting. The application of an electronic emergency department syndromic surveillance system proved valuable and timely in informing public health activities following a natural disaster in New South Wales.
