Evaluation of the Australian first few X household transmission project for COVID-19.

BACKGROUND: The Australian First Few X (FFX) Household Transmission Project for COVID-19 was the first prospective, multi-jurisdictional study of its kind in Australia. The project was undertaken as a partnership between federal and state health departments and the Australian Partnership for Preparedness Research on Infectious Disease Emergencies (APPRISE) and was active from April to October 2020. METHODS: We aimed to identify and explore the challenges and strengths of the Australian FFX Project to inform future FFX study development and integration into pandemic preparedness plans. We asked key stakeholders and partners involved with implementation to identify and rank factors relating to the strengths and challenges of project implementation in two rounds of modified Delphi surveys. Key representatives from jurisdictional health departments were then interviewed to contextualise findings within public health processes and information needs to develop a final set of recommendations for FFX study development in Australia. RESULTS: Four clear recommendations emerged from the evaluation. Future preparedness planning should aim to formalise and embed partnerships between health departments and researchers to help better integrate project data collection into core public health surveillance activities. The development of functional, adaptable protocols with pre-established ethics and governance approvals and investment in national data infrastructure were additional priority areas noted by evaluation participants. CONCLUSION: The evaluation provided a great opportunity to consolidate lessons learnt from the Australian FFX Household Transmission Project. The developed recommendations should be incorporated into future pandemic preparedness plans in Australia to enable effective implementation and increase local utility and value of the FFX platform within emergency public health response.

Ezidi voices: The communication of COVID-19 information amongst a refugee community in rural Australia- a qualitative study.

BACKGROUND: There is growing evidence that government health information related to COVID-19 has failed to adequately reach culturally and linguistically diverse (CALD) populations in Australia. Refugees are a unique sub-set of the CALD communities and are subject to numerous barriers preventing adequate health care, both pre- and post-migration. The barriers are accentuated during emergencies, such as a pandemic, as a result of an intersection of various social and economic inequalities. The recently resettled Ezidi refugee community in a regional area of Australia is an example of a community sitting at the intersection of various inequities and thus at greater risk from COVID-19. The purpose of this study is to describe the experiences of the Ezidi in a regional area with COVID-19 information and how this has been communicated to and shared within this group; what barriers the community may experience in accessing COVID-19 information; and how the government-led COVID-19 information communication could be improved. METHODS: This qualitative study was designed to explore the perceptions and views of the Ezidi and service providers regarding COVID-19 messaging. Multicultural and Refugee Health staff facilitated interviews with four local service providers and ten Ezidi community members, including seven influential leaders. Thematic analysis was employed across individual, pair and group data analysis. Similar categories were grouped into themes. RESULTS: The main findings of the study are: the refugee experience influences the communication of COVID-19 messages; cultural, social and gender norms influence responses to COVID-19; trusted individuals and service providers are key in communities' uptake of COVID-19 messages; currently available governmental COVID-19 information resources and sharing strategies were found unhelpful and inappropriate; COVID-19 communiqués and message delivery for this regional minority refugee community can be improved. CONCLUSION: The recently resettled Ezidi community, and likely other similar communities, would benefit from tailored engagement by government organisations, as well as settlement services to improve the communication of COVID-19 health information and reduce related inequities.

Factors contributing to the sharing of COVID-19 health information amongst refugee communities in a regional area of Australia: a qualitative study.

BACKGROUND: The COVID-19 pandemic has had a disproportionate impact on culturally and linguistically diverse (CALD) groups worldwide. Newly emerging CALD populations formed by recently arrived refugees are predisposed to even greater health disadvantages due to complexities of the refugee experience. The aim of this study was to explore how culture, refugee experiences and existing relationships shaped what COVID-19 messages were listened to and shared during the early-mid phases of the pandemic. The work focused on three newly emerging refugee groups in the Hunter New England region, Australia: Afghan, Congolese and Syrian communities. METHODS: Qualitative, semi-structured interviews were conducted to explore the experiences and stories of 15 adult community members, nine influential members and six service providers. All community members arrived in Australia on or after January 2014. Interpreter-assisted interviews were conducted with small groups or individuals, audio-recorded and transcribed verbatim in English. Three levels of thematic data analysis were employed to uncover the important issues and experiences of the participants. RESULTS: Three key themes and several subthemes were identified. The themes were: 1) Experience as a refugee uniquely influences COVID-19 message communication; 2) Refugee groups use diverse practices when accessing and sharing COVID-19 messages; and 3) Official government messages could be improved by listening and tailoring to community needs. CONCLUSIONS: Effective health messaging relies on reaching communities in a culturally acceptable and meaningful way. Official COVID-19 messages can be tailored to engage newly emerging communities by improving the quality of the content, delivery and format whilst working collaboratively with communities and trusted service providers. Further mutual research is needed to understand emerging communities' viewpoints. The use of culturally informed approaches is recommended.

Tuberculosis care designed with barramarrany (family): Participatory action research that prioritised partnership, healthy housing and nutrition.

ISSUE ADDRESSED: Ongoing tuberculosis (TB) transmission in Aboriginal communities in Australia is unfair and unacceptable. Redressing the inequity in TB affecting Aboriginal peoples is a priority in Australia's Strategic Plan for Tuberculosis Control. Improving TB care needs not to just identify barriers but do something about them. Privileging the voices of Aboriginal people affected by TB is essential to identify effective and enabling strategies. METHODS: A barramarrany (Aboriginal family) affected by recurring TB partnered with TB and Environmental Health teams using a participatory action research (PAR) methodology to improve housing health hardware and nutrition alongside biomedical TB prevention and care. A combination of the Ottawa Charter for Health Promotion; the International "End TB" Strategy; and Aboriginal barramarrany leadership, worldviews and traditional values guided actions to reduce TB transmission. RESULTS: Together the partners improved housing hardware and access to nutritious food, so the barramarrany could create a setting for good health and wellbeing. These actions supported the barramarrany to regain the physical, social and emotional wellbeing to deal with day-to-day challenges and stresses. The barramarrany were able to better sustain supportive relationships; grow, prepare and eat healthy food; and participate in health care activities. The barramarrany could better engage with medical approaches for TB and four barramarrany members completed TB treatment. The PAR action-project enabled and supported early TB diagnosis, treatment and prevention. CONCLUSION: Amplifying the voices of Aboriginal people and shared ownership of TB diagnosis, treatment and prevention by the barramarrany, was underpinned with principles of self-determination, capacity building and social justice. This PAR action-project provides further evidence that improving housing and nutrition can assist in Ending TB while improving wellbeing. SO WHAT?: Our action-research project undertaken within a PAR framework demonstrates the implementation of End TB Strategies by utilising the Ottawa Charter's five actions to promote health, by understanding and centralising the social determinants of health.

Systematic literature review to identify methods for treating and preventing bacterial skin infections in Indigenous children.

BACKGROUND/OBJECTIVES: Bacterial skin infections in Indigenous children in Australia frequently lead them to access primary health care. This systematic review aims to identify and analyse available studies describing the treatment and prevention of bacterial skin infections in Indigenous children. METHODS: Electronic databases including Scopus, MEDLINE, CINAHL, ProQuest, Informit and Google Scholar were searched. Studies in English published between August 1994 and September 2016, with the subject of bacterial skin infections involving Indigenous children and conducted in Australia, New Zealand, the USA or Canada were selected. RESULTS: Initially 1474 articles were identified. After the application of inclusion and exclusion criteria, 10 articles remained. Strategies for the treatment and prevention of bacterial skin infections included the management of active infections and lesions, improving environmental and personal hygiene, the installation of swimming pools and screening and treatment. CONCLUSION: There is a need for more, rigorous, large-scale studies to develop evidence for appropriate, culturally acceptable methods to prevent and manage bacterial skin infections in Indigenous children in Australia. The problem is complex with multiple determinants. Until underlying socioeconomic conditions are addressed skin infections will continue to be a burden to communities.

Reducing recurrence of bacterial skin infections in Aboriginal children in rural communities: new ways of thinking, new ways of working.

Reports from health workers, school staff and community members in rural NSW suggested that bacterial skin infections are a significant health issue for Aboriginal children and their families, affecting quality of life and contributing to poor school attendance. Current NSW treatment guidelines do not incorporate important sociocultural factors or ways of living in Aboriginal communities. The aim of this qualitative study was to gain a deeper understanding of the experience of parents and carers of Aboriginal children affected by skin infections and of other community members, health workers and school staff, and what actions have been considered successful or unsuccessful in reducing the recurrence of infection. This study used a Participatory Action Research methodology. Interviews and focus groups were conducted with 38 health workers and managers, school staff, community members and parents and carers. Themes that emerged included: (i) skin infections have become normalised; (ii) skin infections are, in part, a consequence of transgenerational trauma; (iii) skin infections are interwoven with social determinants; (iv) families have survived but more could thrive; and (v) something can and should be done about the problem. The findings of this study will inform the development of more effective and acceptable options to reduce skin infections in Aboriginal children.

Closing the gap in Australian Aboriginal infant immunisation rates -- the development and review of a pre-call strategy.

BACKGROUND: Improving timely immunisation is key to closing the inequitable gap in immunisation rates between Aboriginal children and non-Indigenous children. Aboriginal Immunisation Officers were employed in Hunter New England Local Health District (HNELHD), New South Wales (NSW), Australia, to telephone the families of all Aboriginal infants prior to the due date for their first scheduled vaccination. METHODS: Aboriginal Immunisation Officers contacted the families of Aboriginal children born in the Hunter New England Local Health District (HNELHD) by telephone before their due immunisation date (pre-call) to provide the rationale for timely immunisation, and to facilitate contact with culturally safe local immunisation services if this was required. The impact of this strategy on immunisation coverage rates is reviewed. RESULTS: For the period March 2010 to September 2014 there was a significant increase in immunisation coverage rate for Aboriginal children at 12 months of age in HNELHD (p < 0.0001). The coverage in the rest of NSW Aboriginal children also increased but not significantly (p = 0.218). Over the full study period there was a significant decrease in the immunisation coverage gap between Aboriginal children and non-Indigenous children in HNELHD (p < 0.0001) and the rest of NSW (p = 0.004). The immunisation coverage gap between Aboriginal and non-Indigenous infants decreased at a significantly faster rate in HNELHD than the rest of NSW (p = 0.0001). By the end of the study period in 2014, immunisation coverage in HNELHD Aboriginal infants had surpassed that of non-Indigenous infants by 0.8 %. CONCLUSIONS: The employment of Aboriginal immunisation officers may be associated with closing of the gap between Aboriginal and non-Indigenous infants' immunisation coverage in HNELHD and NSW. The pre-call telephone strategy provided accelerated benefit in closing this gap in HNELHD.

Steps on a journey to TB control in Solomon Islands: a cross-sectional, mixed methods pre-post evaluation of a local language DVD.

BACKGROUND: In Solomon Islands many people with Tuberculosis (TB) have challenges in accessing services because of socio-cultural, geographic and health service reasons, resulting in delays in TB treatment and low detection rates. The purpose of this project was to (i) develop a local language audio-visual resource (DVD) about TB (ii) share this resource with people in remote villages and (iii) evaluate the process and outcomes. METHODS: The project involved the development and evaluation of a DVD in local Kwaio language. The DVD included five short videos based on the Australian Respiratory Council TB Education Flipchart. The DVD also included short videos of: traditional music/chanting (ai'imae); drama that presented an allegory of TB; and a short documentary on the redevelopment of the local TB Ward. A mixed-methods approach evaluated changes in TB knowledge and investigated the impact of the DVD. RESULTS: The DVD was recorded and produced in March-June 2013 and screened in 41 villages and hamlets. The pre-post DVD survey was completed by 64% (255/400) of people who viewed the DVD in the villages. Pre-DVD survey responses showed a moderate to high knowledge about TB signs, symptoms and treatment but 76/255 (30%) stated TB was caused by sorcery and 85/255 (33%) incorrectly stated that TB medication should be stopped when a patient feels better. The post-DVD survey showed a significant increase in people in coastal villages reporting (i) a 3-week cough would trigger a medical assessment and (ii) TB is mainly spread through the air. Statements that TB is not caused by sorcery increased post-DVD in both coastal and mountain villages, however belief in sorcery in mountain villages remained high at 20/70 (29%). CONCLUSIONS: The local DVD resource was developed within local cultural understandings and oral traditions of Kwaio people. Using modern but accessible DVD technology generated a lot of interest about the disease and the stories. The project evaluation indicates that current delays in seeking treatment may be more due to socio-cultural and health service factors than awareness of the disease. Therefore the development of TB services, including TB education, which are culturally sensitive, remains important.

Mental health issues from rising sea level in a remote coastal region of the Solomon Islands: current and future.

OBJECTIVE: There is little published research about mental health and climate change in the Pacific, including Solomon Islands. Solomon Islands has one of the highest rates of sea-level rise globally. The aim of this research was to document mental health issues related to sea-level rise for people in East Malaita, Solomon Islands. METHOD: A cross-sectional study was carried out in six low-lying villages in East Malaita, Solomon Islands. The researcher travelled to villages by dugout canoe. In addition to quantitative, closed-ended questions, open-ended questions with villagers explored individual and community responses to rising sea level. RESULTS: Of 60 people asked, 57 completed the questionnaire. Of these, 90% reported having seen a change in the weather patterns. Nearly all participants reported that sea-level rise is affecting them and their family and is causing fear and worry on a personal and community level. Four themes emerged from the qualitative analysis: experience of physical impacts of climate change; worry about the future; adaptation to climate change; government response needed. CONCLUSION: Given predictions of ongoing sea-level rise in the Pacific it is essential that more research is conducted to further understand the human impact of climate change for small island states which will inform local, provincial and national-level mental health responses.

Communicable diseases in rural and remote Australia: the need for improved understanding and action.

INTRODUCTION: Rural and remote communities of Australia, particularly those including Aboriginal people, experience greater morbidity and mortality across a range of health outcomes compared to urban communities. Previous national data have demonstrated that rural and remote communities experience a disproportionate burden of communicable diseases compared to their urban counterparts. This systematic review was undertaken to describe the types of research that have explored the epidemiology of communicable diseases in rural and remote communities in Australia, with particular reference to the social determinants of health. METHODS: We conducted a keyword search of several databases (EMBASE, MEDLINE/PubMed, RURAL, Aboriginal and Torres Strait Islander Health Database, Web of Science Core Collection, and Google and Google Scholar websites) for peer-reviewed and grey literature that described or analysed the epidemiology of communicable diseases in rural and/or remote communities of Australia from 2004 to 2013. Exclusion criteria were applied to keep the review focused on rural and/or remote communities and the population-level epidemiological analysis of communicable diseases. RESULTS: From 2287 retrieved articles, a total of 50 remained after applying exclusion criteria. The majority of included articles were descriptive studies (41/50). Seven of the total 50 articles contained analytical studies; one systematic literature review and one experimental study were also identified. Due to the diversity of approaches in measuring disease burden, we performed a narrative synthesis of the articles according to the review objectives. Most of the articles investigated the disease burden in remote (n=37/50) and Aboriginal communities only (n=21/50). The studies highlighted a high prevalence or incidence of skin, eye and respiratory infections for remote Aboriginal communities, particularly children over the past decade. There was emerging evidence to suggest that housing and social conditions play an important role in determining the risk of skin, ear, respiratory and gastrointestinal infections in children. Other health service and sociocultural factors were also discussed by authors as influencing the epidemiology of communicable diseases in rural and remote communities. CONCLUSIONS: This systematic review identified several communicable diseases that continue to cause considerable morbidity in remote Aboriginal communities, including skin, eye and respiratory infections, particularly for children. Overall there is a substantial amount of descriptive epidemiology published, but few analytical or experimental studies. Despite a lack of empirical investigation into the social determinants of the burden of communicable disease, there is emerging evidence that has demonstrated a significant association between housing conditions and skin, ear, respiratory and gastrointestinal infections in children. There is also growing recognition of other social and environmental factors that can influence the burden of diseases in rural and remote communities. Further investment into higher quality community-based research that addresses the social determinants of communicable diseases in remote communities is warranted. The lack of research investigating zoonoses and tropical diseases was noted.

Using a participatory action research framework to listen to Aboriginal and Torres Strait Islander people in Australia about pandemic influenza.

INTRODUCTION: This article describes the use and effectiveness of the participatory action research (PAR) framework to better understand community members' perceptions and risks of pandemic influenza. In 2009, the H1N1 influenza pandemic affected Indigenous populations more than non-Indigenous populations in Oceania and the Americas. Higher prevalence of comorbidities (diabetes, obesity, asthma and chronic obstructive pulmonary disease) as well as pregnancy in Indigenous communities may have contributed to the higher risks of severe disease. Social disparity, institutionalised racism within health services and differences in access to culturally safe health services have also been reported as contributors to disadvantage and delayed appropriate treatment. METHODS: Given these factors and the subsequent impact they had on Australian Aboriginal and Torres Strait Islander communities, the authors set out to ensure that the Australian national, state and territory pandemic plans adequately reflected the risk status of Aboriginal and Torres Strait Islander peoples and promoted meaningful engagement with communities to mitigate this risk. A national study explored the views of Aboriginal and Torres Strait Islander people and their experiences with H1N1 and used a qualitative PAR framework that was effective in gaining deep understandings from participants. Aboriginal and Torres Strait Islander community-controlled organisations and health services were involved in the implementation, interpretation and monitoring of this project. RESULTS: As a result, important features of the implementation of this PAR framework with Aboriginal and Torres Strait Islander communities and organisations emerged. These features included the importance of working in a multidisciplinary team with Aboriginal and Torres Strait Islander researchers; the complexities and importance of obtaining multi-site human research ethics approval processes; the importance and value of building the research capacity of both experienced and novice researchers in PAR; the need to use localised sampling protocols; and the process of undertaking a collective research process and enacting action research and feedback. CONCLUSIONS: The most effective responses of this project were embedded in pre-existing relationships with individuals within organisations that had been established over a long period of time between Aboriginal medical services and investigators; however, research relationships established specifically for the purposes of the project were less successful because of changes in personnel and organisational support. The participatory approach used in this study has the potential to be applied to vulnerable populations in other countries.

Understanding human - bat interactions in NSW, Australia: improving risk communication for prevention of Australian bat lyssavirus.

BACKGROUND: Australian bat lyssavirus (ABLV) infects a number of flying fox and insectivorous bats species in Australia. Human infection with ABLV is inevitably fatal unless prior vaccination and/or post-exposure treatment (PET) is given. Despite ongoing public health messaging about the risks associated with bat contact, surveillance data have revealed a four-fold increase in the number of people receiving PET for bat exposure in NSW between 2007 and 2011. Our study aimed to better understand these human - bat interactions in order to identify additional risk communication messages that could lower the risk of potential ABLV exposure. All people aged 18 years or over whom received PET for non-occupation related potential ABLV exposure in the Hunter New England Local Health District of Australia between July 2011 and July 2013 were considered eligible for the study. Eligible participants were invited to a telephone interview to explore the circumstances of their bat contact. Interviews were then transcribed and thematically analysed by two independent investigators. RESULTS: Of 21 eligible participants that were able to be contacted, 16 consented and participated in a telephone interview. Participants reported bats as being widespread in their environment but reported a general lack of awareness about ABLV, particularly the risk of disease from bat scratches. Participants who attempted to 'rescue' bats did so because of a deep concern for the bat's welfare. Participants reported a change in risk perception after the exposure event and provided suggestions for public health messages that could be used to raise awareness about ABLV. CONCLUSIONS: Reframing the current risk messages to account for the genuine concern of people for bat welfare may enhance the communication. The potential risk to the person and possible harm to the bat from an attempted 'rescue' should be promoted, along with contact details for animal rescue groups. The potential risk of ABLV from bat scratches merits greater emphasis.

A systematic literature review of pediculosis due to head lice in the Pacific Island Countries and Territories: what country specific research on head lice is needed?

BACKGROUND: Lack of guidelines on control of pediculosis in the Solomon Islands led to a search for relevant evidence on head lice in the Pacific Island Countries and Territories (PICTs). The aim of this search was to systematically evaluate evidence in the peer reviewed literature on pediculosis due to head lice (Pediculus humanus var capitis) in the 22 PICTs from the perspective of its value in informing national guidelines and control strategies. METHODS: PubMed, Web of Science, CINAHL and Scopus were searched using the terms (pediculosis OR head lice) AND each of the 22 PICTs individually. PRISMA methodology was used. Exclusion criteria were: i) not on topic; ii) publications on pediculosis not relevant to the country of the particular search; iii) in grey literature. RESULTS: Of 24 publications identified, only 5 were included. Four related to treatment and one to epidemiology. None contained information relevant to informing national guidelines. CONCLUSIONS: Current local evidence on head lice in the PICTs is minimal and totally inadequate to guide any recommendations for treatment or control. We recommend that local research is required to generate evidence on: i) epidemiology; ii) knowledge, attitudes and practices of health care providers and community members; iii) efficacy of local commercially available pharmaceutical treatments and local customary treatments; iv) acceptability, accessibility and affordability of available treatment strategies; and iv) appropriate control strategies for families, groups and institutions. We also recommend that operational research be done by local researchers based in the PICTs, supported by experienced head lice researchers, using a two way research capacity building model.

Diagnosis and management of zoonoses - a tool for general practice.

BACKGROUND: Zoonotic infections such as Q fever, brucellosis and leptospirosis can lead to serious complications but pose diagnostic and management challenges to general practitioners (GPs) as patients often present with non-specific symptoms such as fever. OBJECTIVE: To develop a tool to assist GPs in the diagnosis and management of common zoonotic infections DISCUSSION: An algorithm was developed with advice and comments from GPs, laboratory specialists and infectious disease specialists. Emphasis is placed on understanding patient risk factors, such as non-household contact with animals, excluding other possible causes of fever, such as influenza, and commencing empirical treatment as soon as a zoonotic infection is suspected. The algorithm is not exhaustive and GPs are urged to consult infectious disease specialists and medical microbiologists for further guidance if required.

Members' experiences and perceptions of participating in an Australian Regional One Health Network.

BACKGROUND: The One Health framework is intended to optimise the interdependent health of humans, animals and ecosystems. It relies on effective collaborations across disciplines, sectors and communities. One Health networks have become increasingly important platforms for encouraging, creating and supporting collaborations. Their success is usually judged by evaluations of their outputs. However, there is also a need to understand member experiences and perceptions of the networks in which they participate. To that end, we undertook the first membership survey of a One Health network that was established in Australia in 2005. METHODS: An online membership survey was created, comprising closed and open-ended questions. RESULTS: Around one third of the Regional One Health Partnership ('the Network') participated in the study (33 members). Participants contributed a combined total of 170 years of experience in the Network and 414 years of combined experience working in/on One Health. The Network has provided excellent opportunities for cross sectoral collaboration that would otherwise not have been possible. Findings also highlighted the intangible benefits of membership such as the creation of a collaborative support group for emerging and established One Health practitioners. CONCLUSIONS: The Network plays an important role in One Health collaborations in New South Wales and further afield. Commensurate with the literature on One Health collaborations globally, we identified a need for greater diversity amongst members, especially from First Nations people, local communities, non-government organisations and wildlife/environment experts, as well as concerted attempts to identify policy implications. Our membership survey tool could be adapted for future One Health Network membership surveys in Australia and internationally.

Potential for the Australian and New Zealand paediatric intensive care registry to enhance acute flaccid paralysis surveillance in Australia: a data-linkage study.

BACKGROUND: Australia uses acute flaccid paralysis (AFP) surveillance to monitor its polio-free status. The World Health Organization criterion for a sensitive AFP surveillance system is the annual detection of at least one non-polio AFP case per 100,000 children aged less than 15 years, a target Australia has not consistently achieved. Children exhibiting AFP are likely to be hospitalised and may be admitted to an intensive care unit. This provides a potential opportunity for active AFP surveillance. METHODS: A data-linkage study for the period from 1 January 2005 to 31 December 2008 compared 165 non-polio AFP cases classified by the Polio Expert Panel with 880 acute neurological presentations potentially compatible with AFP documented in the Australian and New Zealand Paediatric Intensive Care (ANZPIC) Registry. RESULTS: Forty-two (25%) AFP cases classified by the Polio Expert Panel were matched to case records in the ANZPIC Registry. Of these, nineteen (45%) cases were classified as Guillain-Barré syndrome on both registries. Ten additional Guillain-Barré syndrome cases recorded in the ANZPIC Registry were not notified to the national AFP surveillance system. CONCLUSIONS: The identification of a further ten AFP cases supports inclusion of intensive care units in national AFP surveillance, particularly specialist paediatric intensive care units, to identify AFP cases that may not otherwise be reported to the national surveillance system.

Uptake of influenza vaccine by pregnant women: a cross-sectional survey.

OBJECTIVES: To determine influenza vaccination coverage among pregnant women in New South Wales, and factors associated with vaccine uptake during pregnancy. DESIGN, SETTING AND PARTICIPANTS: Quantitative self-administered survey of pregnant women, using a non-random, stratified sample from antenatal clinics at three demographically diverse hospitals in NSW during the influenza season of 2011. MAIN OUTCOME MEASURES: Self-reported influenza vaccine uptake while pregnant; and attitudes, barriers and facilitators to vaccine acceptance during pregnancy. RESULTS: Of 939 women approached, 815 participated (87%). Influenza vaccine uptake in pregnant women was 27%. Women who had received a recommendation to have the vaccine were 20.0 times (95% CI, 10.9-36.9) more likely to have been vaccinated. Forty-two per cent recalled receiving a recommendation to be vaccinated. Other factors associated with vaccination were study site, perceived infection severity, overall feelings toward vaccination during pregnancy, vaccine accessibility, and willingness to take up the vaccine if recommended. Concern about the baby's safety was negatively associated with vaccination (odds ratio, 0.5; 95% CI, 0.2-0.9), but 68% (95% CI, 63%-71%) of women who expressed concern agreed they would have the vaccine if their health care professional recommended it. CONCLUSION: Recommendation from a health care provider is strongly associated with influenza vaccine uptake among pregnant women and can overcome their concerns about safety, but less than half the women surveyed reported receiving such a recommendation. Educational material targeting pregnant women and professional education and support for antenatal health care providers are needed to increase awareness and recommendation.

Local level epidemiological analysis of TB in people from a high incidence country of birth.

BACKGROUND: The setting for this analysis is the low tuberculosis (TB) incidence state of New South Wales (NSW), Australia. Local level analysis of TB epidemiology in people from high incidence countries-of-birth (HIC) in a low incidence setting has not been conducted in Australia and has not been widely reported. Local level analysis could inform measures such as active case finding and targeted earlier diagnosis. The aim of this study was to use a novel approach to identify local areas in an Australian state that have higher TB rates given the local areas' country of birth profiles. METHODS: TB notification data for the three year period 2006-2008 were analysed by grouping the population into those from a high-incidence country-of-birth and the remainder. RESULTS: During the study period there were 1401 notified TB cases in the state of NSW. Of these TB cases 76.5% were born in a high-incidence country. The annualised TB notification rate for the high-incidence country-of-birth group was 61.2/100,000 population and for the remainder of the population was 1.8/100,000. Of the 152 Local Government Areas (LGA) in NSW, nine had higher and four had lower TB notification rates in their high-incidence country-of-birth populations when compared with the high-incidence country-of-birth population for the rest of NSW. The nine areas had a higher proportion of the population with a country of birth where TB notification rates are >100/100,000. Those notified with TB in the nine areas also had a shorter length of stay in Australia than the rest of the state. The areas with higher TB notification rates were all in the capital city, Sydney. Among LGAs with higher TB notification rates, four had higher rates in both people with a high-incidence country of birth and people not born in a high-incidence country. The age distribution of the HIC population was similar across all areas, and the highest differential in TB rates across areas was in the 5-19 years age group. CONCLUSIONS: Analysing local area TB rates and possible explanatory variables can provide useful insights into the epidemiology of TB. TB notification rates that take country of birth in local areas into account could enable health services to strategically target TB control measures.

Evidence of Cryptosporidium transmission between cattle and humans in northern New South Wales.

Cryptosporidium is an enteric parasite of public health significance that causes diarrhoeal illness through faecal oral contamination and via water. Zoonotic transmission is difficult to determine as most species of Cryptosporidium are morphologically identical and can only be differentiated by molecular means. Transmission dynamics of Cryptosporidium in rural populations were investigated through the collection of 196 faecal samples from diarrheic (scouring) calves on 20 farms and 63 faecal samples from humans on 14 of these farms. The overall prevalence of Cryptosporidium in cattle and humans by PCR and sequence analysis of the 18S rRNA was 73.5% (144/196) and 23.8% (15/63), respectively. Three species were identified in cattle; Cryptosporidium parvum, Cryptosporidium bovis and Cryptosporidium ryanae, and from humans, C. parvum and C. bovis. This is only the second report of C. bovis in humans. Subtype analysis at the gp60 locus identified C. parvum subtype IIaA18G3R1 as the most common subtype in calves. Of the seven human C. parvum isolates successfully subtyped, five were IIaA18G3R1, one was IIdA18G2 and one isolate had a mix of IIaA18G3R1 and IIdA19G2. These findings suggest that zoonotic transmission may have occurred but more studies involving extensive sampling of both calves and farm workers are needed for a better understanding of the sources of Cryptosporidium infections in humans from rural areas of Australia.
