Successful introgression of wMel Wolbachia into Aedes aegypti populations in Fiji, Vanuatu and Kiribati.

Pacific Island countries have experienced periodic dengue, chikungunya and Zika outbreaks for decades. The prevention and control of these mosquito-borne diseases rely heavily on control of Aedes aegypti mosquitoes, which in most settings are the primary vector. Introgression of the intracellular bacterium Wolbachia pipientis (wMel strain) into Ae. aegypti populations reduces their vector competence and consequently lowers dengue incidence in the human population. Here we describe successful area-wide deployments of wMel-infected Ae. aegypti in Suva, Lautoka, Nadi (Fiji), Port Vila (Vanuatu) and South Tarawa (Kiribati). With community support, weekly releases of wMel-infected Ae. aegypti mosquitoes for between 2 to 5 months resulted in wMel introgression in nearly all locations. Long term monitoring confirmed a high, self-sustaining prevalence of wMel infecting mosquitoes in almost all deployment areas. Measurement of public health outcomes were disrupted by the Covid19 pandemic but are expected to emerge in the coming years.

Redesigning Prehospital Care: Fiji's Response to the COVID-19 Pandemic.

The benefits of emergency care systems in low- and middle-income countries are well-described. Passed in the wake of the coronavirus disease 2019 (COVID-19) pandemic, the World Health Assembly (WHA) Resolution 76.2 emphasizes the importance of communication, transportation and referral mechanisms, and the linkages between communities, primary care, and hospital care. Literature describing prehospital care and ambulance system development is scarce, with little data on the effectiveness and cost effectiveness of different options. Prehospital care systems in Pacific Island countries are under-developed. In Fiji, out-of-hospital care is fragmented with an uncoordinated patchwork of ambulance providers. There is no scope of practice or training requirement for providers and no patient care records. There are no data relating to demand, access, and utilization of ambulance services.In response to a surge of COVID-19 cases in 2021, the Fiji government created a Prehospital Emergency Care Coordination Center (PHECCC) in the capital Suva, which was operational from July-October 2021. Access was via a toll-free number, whereby the public could receive a medical consultation followed by phone advice or dispatch of an ambulance for a home assessment, followed by transportation to hospital, if required. The PHECCC also provided coordination of inter-facility transport and retrieval of the critically ill.The system that was created met many of the prehospital care standards set by emergency care leaders in the region and created the first dataset relating to ambulance demand and utilization. This is the first article to document prehospital system development in the Pacific region.

Effect of COVID-19 on dental service delivery in Fiji: Perspective of Dental Officers (Dos) and Dental Managers (DMs).

BACKGROUND: Corona Virus Disease 2019 (COVID-19) was declared a global pandemic by the World Health Organization (WHO) has had significant impact on dentistry in Fiji. Due to lack of previous study, this study aims to explore the perspective of Dental Officers (DOs) and Dental Managers (DMs) on the effects of COVID-19 on dental service delivery in Fiji Islands. METHODS: This qualitative study was conducted amongst 30 DOs and 17 DMs between 9th August to 12th September, 2021. It was conducted in the government dental clinics, private dental clinics and the School of Dentistry and Oral Health clinic (SDOH), in the Central Division, Fiji. The study settings were randomly selected. Purposive sampling method was used for the selection of participants who met the study criteria. Semi-structure open ended questionnaires were used for data collection through in-depth interviews via zoom. Manual thematic analysis of the data was conducted to derive themes and codes. RESULTS: The participants interviewed for the study included more female DOs (66.7%) and male DMs (58.8%). Seven themes emerged from data analysis: range of services delivered, appointment versus walk-in patients for aerosol generating procedures (AGPs), impact of pandemic on clinic opening hours, impact of COVID-19 on patient numbers, quality of services delivered, resources and infrastructure, perceptions about the burden of disease. CONCLUSION: COVID-19 has significantly affected dental service delivery. Mostly emergency dental services were delivered. AGPs were delivered on appointment basis. Most participants stated the quality of services had improved. Participants stated that they were not given adequate resources and the infrastructure was not up to standard to provide dental services during the pandemic. The dental disease burden had increased during the pandemic as per the participants. Future research can be conducted amongst other dental professionals in other divisions of the country.

Population-based assessment of cardiovascular complications of rheumatic heart disease in Fiji: a record-linkage analysis.

OBJECTIVE: To determine population-based rates of non-fatal complications of rheumatic heart disease (RHD). DESIGN: Retrospective cohort study based on multiple sources of routine clinical and administrative data amalgamated by probabilistic record-linkage. SETTING: Fiji, an upper-middle-income country, where most of the population has access to government-funded healthcare services. PARTICIPANTS: National cohort of 2116 patients with clinically apparent RHD aged 5-69 years during 2008 and 2012. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was hospitalisation for any of heart failure, atrial fibrillation, ischaemic stroke and infective endocarditis. Secondary outcomes were first hospitalisation for each of the complications individually in the national cohort as well as in hospital (n=1300) and maternity (n=210) subsets. Information on outcomes was obtained from discharge diagnoses coded in the hospital patient information system. Population-based rates were obtained using relative survival methods with census data as the denominator. RESULTS: Among 2116 patients in the national cohort (median age, 23.3 years; 57.7% women), 546 (25.8%) were hospitalised for an RHD complication, a substantial proportion of all cardiovascular admissions in the country during this period in those aged 0-40 years (heart failure, 210/454, 46.3%; ischaemic stroke 31/134, 23.1%). Absolute numbers of RHD complications peaked during the third decade of life with higher population-based rates in women compared with men (incidence rate ratio 1.4, 95% CI 1.3 to 1.6, p<0.001). Hospitalisation for any RHD complication was associated with substantially increased risk of death (HR 5.4, 95% CI 3.4 to 8.8, p<0.001), especially after the onset of heart failure (HR 6.6, 95% CI 4.8 to 9.1, p<0.001). CONCLUSIONS: Our study defines the burden of RHD-attributable morbidity in the general population of Fiji, potentially reflecting the situation in low-income and middle-income countries worldwide. Hospitalisation for an RHD complication is associated with markedly increased risk of death, re-emphasising the importance of effective early prevention.

Incidence, treatment patterns and clinical outcomes associated with acute kidney injury in Fiji: a retrospective cohort study.

AIM: This study aims to describe the incidence and outcomes of acute kidney injury at Fiji's tertiary referral hospital. METHODS: A retrospective study of adults aged ≥ 18 years hospitalised at the Colonial War Memorial Hospital between 1 January and 30 June, 2015 was conducted. Acute kidney injury was defined using the 2012 Kidney Disease Improving Global Outcomes (KDIGO) guidelines by medical record review. RESULTS: One hundred ten (2.1%) of 5140 hospitalised patients met the diagnostic criteria for acute kidney injury. Fifty-two cases (47%) of acute kidney injury were stage 1, 11 (10%) cases were stage 2, and 47 (43%) cases were stage 3. Acute sepsis (n = 68) and dehydrating illness (n = 52) were the most common causes. Thirty-nine patients had urinalysis and 36 received imaging; none underwent kidney biopsy. Treatment included antibiotics (n = 91), intravenous fluids (n = 84) and vasopressors (n = 25). Twenty-one (19%) patients were treated with intermittent haemodialysis. Forty-seven patients (43%) with acute kidney injury died including 16 (76%) dialysed patients. Crude mortality at 7 days was 19 (40%). Of the 63 patients who survived their primary illness, 29 (46%) had a follow-up assessment at 3 months. CONCLUSION: In patients needing hospitalisation for acute kidney injury in Fiji, the most common causes were sepsis and dehydration. Mortality was high, in particular in those who received dialysis. Follow-up after acute kidney injury is incomplete.

Implementation and use of a national electronic dashboard to guide COVID-19 clinical management in Fiji.

Problem: From April to September 2021, Fiji experienced a second wave of coronavirus disease (COVID-19) precipitated by the Delta variant of concern, prompting a need to strengthen existing data management of positive COVID-19 cases. Context: With COVID-19 cases peaking at 1405 a day and many hospital admissions, the need to develop a better way to visualize data became clear. Action: The Fiji Ministry of Health and Medical Services, the World Health Organization and the United Nations Office for the Coordination of Humanitarian Affairs collaborated to develop an online clinical dashboard to support better visualization of case management data. Outcome: The dashboard was used across Fiji at national, divisional and local levels for COVID-19 management. At the national level, it provided real-time reports describing the surge pattern, severity and management of COVID-19 cases across the country during daily incident management team meetings. At the divisional level, it gave the divisional directors access to timely information about hospital and community isolation of cases. At the hospital level, the dashboard allowed managers to monitor trends in isolated cases and use of oxygen resources. Discussion: The dashboard replaced previous paper-based reporting of statistics with delivery of trends and real-time data. The team that developed the tool were situated in different locations and did not meet physically, demonstrating the ease of implementing this online tool in a resource-constrained setting. The dashboard is easy to use and could be used in other Pacific island countries and areas.

Local and Traditional Ecological Knowledge of Fish Poisoning in Fiji.

Fish poisoning (FP) affects human health, trade and livelihood in Fiji, where management has depended mainly on traditional ecological knowledge (TEK). This paper investigated and documented this TEK through a 2-day stakeholder workshop, group consultation, in-depth interviews, field observations, and analyses of survey data from the Ministry of Fisheries, Fiji. Six TEK topics were identified and classified as preventative and treatment options. The preventive approach involves identifying toxic reef fishes, the spawning season of edible seaworms, hotspot areas of toxic fishes, folk tests, and locating and removing toxic organs. For example, 34 reef fish species were identified as toxic. The FP season was associated with the spawning of balolo (edible seaworm) and the warmer months of October to April (cyclone seasons). Two well-known toxic hotspots associated with an abundance of bulewa (soft coral) were identified. Folk tests and locating and removing toxic fish organs are also practised for moray eels and pufferfish. At the same time, various locally available herbal plants are used to treat FP as the second line of defence. The TEK collated in this work can help local authorities better identify the sources of toxicity, and applying TEK preventive measures could stem the tide of fish poisoning in Fiji.

Developing a Climate Change Risk Perception Model in the Philippines and Fiji: Posttraumatic Growth Plays Central Role.

BACKGROUND: This two-study paper developed a climate change risk perception model that considers the role of posttraumatic growth (i.e., a reappraisal of life priorities and deeper appreciation of life), resource loss, posttraumatic stress, coping, and social support. METHOD: In Study 1, participants were 332 persons in the Philippines who experienced Super Typhoon Haiyan. In Study 2, participants were 709 persons in Fiji who experienced Cyclone Winston. Climate change can increase the size and destructive potential of cyclones and typhoons as a result of warming ocean temperatures, which provides fuel for these storms. Participants completed measures assessing resource loss, posttraumatic stress, coping, social support, posttraumatic growth, and climate change risk perception. RESULTS: Structural equation modeling was used to develop a climate change risk perception model with data collected in the Philippines and to confirm the model with data collected in Fiji. The model showed that climate change risk perception was influenced by resource loss, posttraumatic stress, coping activation, and posttraumatic growth. The model developed in the Philippines was confirmed with data collected in Fiji. CONCLUSIONS: Posttraumatic growth played a central role in climate change risk perception. Public health educational efforts should focus on vividly showing how climate change threatens life priorities and that which gives life meaning and can result in loss, stress, and hardship. Disaster response organizations may also use this approach to promote preparedness for disaster threats.

Understanding Sociocultural Influences on Physical Activity in Relation to Overweight and Obesity in a Rural Indigenous Community of Fiji Islands.

INTRODUCTION: Given health disparities and increased rates of obesity and non-communicable diseases seen in Indigenous populations worldwide and the evidence connecting sociocultural knowledge with physical activity, health, and wellbeing, this research was undertaken to understand the social and cultural components contributing to obesity in the Indigenous Fijian rural areas. METHODS: This research is a community-based participatory research (CBPR) project, which engaged community members from a rural iTaukei village in the Fiji Islands. Data collection was carried out through community consultation and semi-structured interviews. The data was analysed using descriptive thematic analysis. RESULTS: Four major themes emerged associated with sociocultural, economic, political, and physical environmental factors. Males emphasised sports and working on farmlands as preferred types of physical activity, while females focused on family activities and daily activities and support for females' separate playgrounds. There was a focus on previous health promotion programs that did not incorporate the cultural values, cultural competence beliefs, and traditional ways of the rural Indigenous Fijian community. CONCLUSION: The healthcare providers and policymakers need to recognise the iTaukei community culture and appreciate traditional methods to promote equitable community participation in decision-making for health promotion. These findings should inform future research and community-based health programs to address the physical activity levels of the rural Indigenous community and may be relevant to other Indigenous peoples.

Rapid SARS-CoV-2 Seroprevalence Survey in Central and Western Divisions of Fiji, 2021.

During November-December 2021, we performed a SARS-CoV-2 seroprevalence survey in Central and Western Divisions of Fiji. A total of 539 participants 8-70 years of age were 95.5% (95% CI 93.4%-97.1%) seropositive, indicating high community levels of immunity. Seroprevalence studies can inform public health responses to emerging SARS-CoV-2 variants.

Prevalence and associated risk factors for mental health problems among young adults in Fiji Island during COVID-19: a cross-sectional study.

Introduction: The COVID-19 pandemic has had a significant impact on mental health globally. To understand the impact of the pandemic on mental health in Fiji, this study aimed to investigate the prevalence of anxiety disorder and depression among the young adults. Method: An online survey was conducted to assess the prevalence of anxiety disorder and depression among the general population in Suva, Fiji during the COVID-19 pandemic. A total of 1,119 Fiji adults participated in the study. The study was conducted between May 20 to June 30, 2022, using a snowball sampling via social media platforms. The Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire (PHQ-9) scales were used to measure anxiety and depression, respectively. The COVID-19 related stressors was evaluated using the adapted SARS stressors assessment. Univariate and multivariate logistic regression analysis was performed to determine the factors influencing mental health among respondents. Results: The result shows that a significant portion of individuals experienced each of the stressors, with the highest prevalence seen for hearing information about the severity of COVID-19. The prevalence of anxiety and depression was found to be 45% and 49%, respectively. Being female, having pre-existing illness and COVID-19 stressors were a risk factor to develop anxiety and depression. On the other hand, employed individuals and having high BMI was a protective factor against developing depression during COVID-19 lockdown. Conclusion: These findings highlight the importance of addressing the mental health needs of the Fijian population during the COVID-19 pandemic and beyond.

Incorporating a gender lens into nutrition and health-related policies in Fiji: analysis of policies and stakeholder perspectives.

BACKGROUND: Gender equality, zero hunger and healthy lives and well-being for all, are three of the Sustainable Development Goals (SDGs) that underpin Fiji's National Development Plan. Work towards each of these goals contributes to the reduction of non-communicable diseases (NCDs). There are gender differences in NCD burden in Fiji. It is, however, unclear whether a gender lens could be more effectively included in nutrition and health-related policies. METHODS: This study consisted of three components: (i) a policy content analysis of gender inclusion in nutrition and health-related policies (n = 11); (ii) policy analysis using the WHO Gender Analysis tool to identify opportunities for strengthening future policy; and (iii) informant interviews (n = 18), to understand perceptions of the prospects for gender considerations in future policies. RESULTS: Gender equality was a goal in seven policies (64%); however, most focused on women of reproductive age. One of the policies was ranked as gender responsive. Main themes from key informant interviews were: 1) a needs-based approach for the focus on specific population groups in policies; 2) gender-related roles and responsibilities around nutrition and health; 3) what is considered "equitable" when it comes to gender, nutrition, and health; 4) current considerations of gender in policies and ideas for further gender inclusion; and 5) barriers and enablers to the inclusion of gender considerations in policies. Informants acknowledged gender differences in the burden of nutrition-related NCDs, yet most did not identify a need for stronger inclusion of gender considerations within policies. CONCLUSIONS: There is considerable scope for greater inclusion of gender in nutrition and health-related policies in Fiji. This could be done by: 1) framing gender considerations in ways that are actionable and inclusive of a range of gender identities; 2) undertaking advocacy through actor networks to highlight the need for gender-responsive nutrition and health-related policies for key stakeholder groups; 3) ensuring that data collected to monitor policy implementation is disaggregated by sex and genders; and 4) promoting equitable participation in nutrition related issues in communities and governance processes. Action on these four areas are likely critical enablers to more gender equitable NCD reduction in Fiji.

Strengthening implementation of diet-related non-communicable disease prevention strategies in Fiji: a qualitative policy landscape analysis.

BACKGROUND: Noncommunicable diseases (NCDs) are the leading cause of death globally, and the World Health Organization (WHO) has recommended a comprehensive policy package for their prevention and control. However, implementing robust, best-practice policies remains a global challenge. In Fiji, despite political commitment to reducing the health and economic costs of NCDs, prevalence of diabetes and cardiovascular disease remain the highest in the region. The objective of this study was to describe the political and policy context for preventing diet-related NCDs in Fiji and policy alignment with WHO recommendations and global targets. We used a case study methodology and conducted (1) semi-structured key informant interviews with stakeholders relevant to diet-related NCD policy in Fiji (n = 18), (2) documentary policy analysis using policy theoretical frameworks (n = 11), (3) documentary stakeholder analysis (n = 7), and (4) corporate political activity analysis of Fiji's food and beverage industry (n = 12). Data were sourced through publicly available documents on government websites, internet searches and via in-country colleagues and analysed thematically. RESULTS: Opportunities to strengthen and scale-up NCD policies in Fiji in line with WHO recommendations included (1) strengthening multisectoral policy engagement, (2) ensuring a nutrition- and health-in-all policy approach, (3) using a whole-of-society approach to tighten political action across sectors, and (4) identifying and countering food industry influence. CONCLUSION: Diet-related NCD policy in Fiji will be strengthened with clearly defined partner roles, responsibilities and accountability mechanisms, clear budget allocation and strong institutional governance structures that can support and counter industry influence. Such initiatives will be needed to reduce the NCD burden in Fiji.

What do university students say about online learning and the COVID-19 pandemic in central Fiji? A qualitative study.

Globally, the spread of COVID-19 has led to the closure of schools, thereby accelerating the expansion of the online learning environment. Though, Fiji National University students' (FNU), had no option than to quickly adopt to this mode of learning, within limited period, their learning experiences are yet to be examined and documented. We used phenomenological study design to explore students' online learning challenges, coping strategies and their perceptions on the causes of COVID-19. A total of 120 in-depth interviews were conducted with FNU students, at different levels and colleges, and analysed thematically, using inductive approach. The three themes emerged included COVID-19 misconception beliefs among students, online learning challenges during the COVID-19 pandemic and online learning coping strategies during the COVID-19 pandemic. The misconception beliefs identified were natural occurrence, manmade for depopulation, unreal/fake and as a means of soliciting for funds. The challenges included ineffective tutorial sessions, lack of learning devices, unstable internet service, inadequate learning environment, socio-cultural practices, feeling of loneliness, anxiety and stress, and difficulties accessing online platforms and acquiring practical skills. The coping strategies used by students ranged from support from family and counsellors, help-seeking, frequent communication, time management, learning flexibility to control over learning environment. The findings highlight the need for policy makers, school managers, lecturers and other key stakeholders to address online learning challenges to improve online learning among FNU students. Relevant information should be provided on the COVID-19 pandemic to clear misconceptions.

Sociocultural Influences Contribute to Overeating and Unhealthy Eating: Creating and Maintaining an Obesogenic Social Environment in Indigenous Communities in Urban Fiji.

Pacific Island countries (PICs), such as Fiji, lead the world statistics in obesity and deaths caused by non-communicable diseases. The impacts of obesity overburden the healthcare system and social services and have major impacts on the Fijian economy. This study is the first of its kind to undertake an in-depth exploration of the determinants of the obesity epidemic in PICs by exploring the sociocultural influences and situations that impact nutrient transitions, overconsumption, and unhealthy eating in an urban indigenous community. In-depth qualitative interviews were conducted with 15 indigenous Fijian women from the largest urban center in Fiji who self-identified as gatekeepers of family meal planning, preparing, and shopping for groceries, fruits, and vegetables. The women identified several cultural norms and expectations of both the individuals providing the food and the individuals consuming the food that create and maintain an obesogenic social environment. Moreover, participants also shared a misplaced value on meat, energy-dense foods, junk food, and fast foods that further contribute to unhealthy eating and overeating within this urban indigenous community. These novel findings highlight the importance of considering sociocultural influences on unhealthy eating and overeating and may be used to assist decision-makers in developing contextualized obesity prevention strategies and health messaging to target obesity in this community.

Estimating the duration of antibody positivity and likely time of Leptospira infection using data from a cross-sectional serological study in Fiji.

BACKGROUND: Leptospirosis is a zoonotic disease prevalent throughout the world, but with particularly high burden in Oceania (including the Pacific Island Countries and Territories). Leptospirosis is endemic in Fiji, with outbreaks often occurring following heavy rainfall and flooding. As a result of non-specific clinical manifestation and diagnostic challenges, cases are often misdiagnosed or under-ascertained. Furthermore, little is known about the duration of persistence of antibodies to leptospirosis, which has important clinical and epidemiological implications. METHODOLOGY AND PRINCIPAL FINDINGS: Using the results from a serosurvey conducted in Fiji in 2013, we fitted serocatalytic models to estimate the duration of antibody positivity and the force of infection (FOI, the rate at which susceptible individuals acquire infection or seroconversion), whilst accounting for seroreversion. Additionally, we estimated the most likely timing of infection. Using the reverse catalytic model, we estimated the duration of antibody persistence to be 8.33 years (4.76-12.50; assuming constant FOI) and 7.25 years (3.36-11.36; assuming time-varying FOI), which is longer than previous estimates. Using population age-structured seroprevalence data alone, we were not able to distinguish between these two models. However, by bringing in additional longitudinal data on antibody kinetics we were able to estimate the most likely time of infection, lending support to the time-varying FOI model. We found that most individuals who were antibody-positive in the 2013 serosurvey were likely to have been infected within the previous two years, and this finding is consistent with surveillance data showing high numbers of cases reported in 2012 and 2013. CONCLUSIONS: This is the first study to use serocatalytic models to estimate the FOI and seroreversion rate for Leptospira infection. As well as providing an estimate for the duration of antibody positivity, we also present a novel method to estimate the most likely time of infection from seroprevalence data. These approaches can allow for richer, longitudinal information to be inferred from cross-sectional studies, and could be applied to other endemic diseases where antibody waning occurs.

Attributable mortality and excess length of stay associated with third-generation cephalosporin-resistant Enterobacterales bloodstream infections: a prospective cohort study in Suva, Fiji.

OBJECTIVES: There are scant primary clinical data on antimicrobial resistance (AMR) burden from low- and middle-income countries (LMICs). We adapted recent World Health Organization methodology to measure the effect of third-generation cephalosporin resistance (3GC-R) on mortality and excess length of hospital stay in Fiji. METHODS: We conducted a prospective cohort study of inpatients with Enterobacterales bloodstream infections (BSIs) at Colonial War Memorial Hospital, Suva. We used cause-specific Cox proportional hazards models to estimate the effect of 3GC-R on the daily risk (hazard) of in-hospital mortality and being discharged alive (competing risks), and we used multistate modelling to estimate the excess length of hospital stay. RESULTS: From July 2020 to February 2021 we identified 162 consecutive Enterobacterales BSIs; 3GC-R was present in 66 (40.7%). Crude mortality for patients with 3GC-susceptible and 3GC-R BSIs was 16.7% (16/96) and 30.3% (20/66), respectively. 3GC-R was not associated with the in-hospital mortality hazard rate (adjusted hazard ratio [aHR] 1.13, 95% confidence interval [CI] 0.51-2.53) or being discharged alive (aHR 0.99, 95% CI 0.65-1.50), whereas Charlson comorbidity index score (aHR 1.62, 95% CI 1.36-1.93) and Pitt bacteraemia score (aHR 3.57, 95% CI 1.31-9.71) were both associated with an increased hazard rate of in-hospital mortality. 3GC-R was associated with an increased length of stay of 2.6 days (95% CI 2.5-2.8). 3GC-R was more common among hospital-associated infections, but genomics did not identify clonal transmission. CONCLUSION: Patients with Enterobacterales BSIs in Fiji had high mortality. There were high rates of 3GC-R, which was associated with increased hospital length of stay but not with in-hospital mortality.

An Economic Analysis of Mumps Vaccination in Fiji: Static Model Simulation of Routine Measles-Mumps-Rubella (MMR) Vaccination Instead of Current Measles-Rubella (MR) Vaccination.

Mumps remains endemic in Fiji, with 7802 cases reported between 2016 and 2018. The introduction of mumps vaccination has been discouraged due to perceptions of mumps as a self-limited disease and the perceived high cost of mumps vaccines. We estimated the benefits and costs of introducing a mumps vaccination program in Fiji. First, we estimated the burden of mumps and mumps-related complications in Fiji based on the reported cases in the Fiji National Notifiable Disease Surveillance System between 2016 and 2018. We then developed a static simulation model with stable mumps herd immunity after routine measles-mumps-rubella (MMR) vaccination. Finally, we compared the estimated economic burden of mumps with current MR vaccination and the assumptive burden of the stable-state simulation model after routine MMR vaccination. The benefit-cost ratios (BCRs) were 2.65 from the taxpayer view and 3.00 from the societal view. A probabilistic sensitivity analysis indicated that the 1st and 99th percentiles of BCRs were 1.4 and 5.2 from the taxpayer's perspective and 1.5 and 6.1 from the societal perspective. From both the taxpayer and societal perspectives, the probability of BCRs greater than 1.0 was 100%. A routine MMR program has value for money from both the taxpayer and societal perspectives. MMR vaccination should be urgently introduced in Fiji.
