Disability and Lower Social Gradient Increased Risk of Depression Among Pre-Elderly in Indonesia: Finding From a Nationwide Health and Socio-Economic Survey.

Prevalence of depression in Indonesia was 6.1% in 2018, while disability was doubled from 11% in 2013 to 22% in 2018. Pre-elderlies are susceptible to experience both disability and depression. We conducted secondary data analysis of nationally representative data to measure the association between disability and depression among pre-elderlies, age 45 to 59 years old. This analysis involved 70,301 pre-elderlies with normal body mass index, and 70,090 with complete data for further analysis with multilevel logistic regression. We found 1.6% pre-elderlies experience depression, 19.1% have disability, while 3.3% of those with disability were depressed. We found likelihood of depression almost three time among pre-elderly with disability (AOR = 2.81). Other variables with independent association are residential area, sex, history of chronic illness, socio-economic, and education level. Preventive measures are needed to improve awareness and to screen for both disability and depression among these age-group, as well as rehabilitative programs to improve their wellbeing.

The short-term effects of COVID-19 on HIV and AIDS control efforts among female sex workers in Indonesia.

BACKGROUND: The COVID-19 pandemic has raised concerns as to its impact on other health programs. One program that appears particularly vulnerable is HIV and AIDS. We undertook an assessment of COVID-19 impact on HIV control efforts in Indonesia for a sub-population that has received little attention in the global literature-female sex workers (FSW). METHODS: The study was undertaken in 23 National AIDS program priority districts. Four sources of monthly data during January-July 2020 were considered. COVID-19 infection data were extracted from national and district surveillance systems. Combination prevention program outputs were reported by civil society organizations (CSOs) providing community support services to FSW. These organizations also undertook monthly scans of levels of commercial sex activity and HIV testing availability. We also considered data from an ongoing HIV community screening trial. The primary mode of analysis entailed comparisons of levels and trends of indicators from the four data series. RESULTS: Commercial sex activity was severely curtailed in April-May in many districts. While recovering to pre-COVID-19 levels in "Localization" areas, the number of active FSW in July was one-third below that in February. HIV testing service availability declined by 50% at health facilities before recovering slowly, while mobile clinic services largely ceased during April-June. Numbers of FSW reached, condoms distributed, FSW tested for HIV, HIV cases detected, and FSW starting treatment all declined precipitously in April/May but had largely recovered to pre-COVID-19 levels by July. We found only a temporary dip in treatment initiation rates among HIV positive FSW and no discernible impact on treatment retention. The HIV community screening trial data revealed significant demand for HIV testing among FSW that was not being met even before the onset of COVID-19. CONCLUSIONS: COVID-19 has had at least short-run economic effects on FSW and the national response to HIV and AIDS targeting FSW. However, the effects appear to have been cushioned by community-based services and support in study districts. The findings make a compelling case for the expansion of community-based services irrespective of the future trajectory of COVID-19. As COVID-19 has not yet been contained, the trajectory of economic activity and service delivery is uncertain.

HIV self-testing for men who have sex with men: an implementation trial in Indonesia.

We investigated oral fluid testing (OFT) among men who have sex with men (MSM) to increase HIV testing in Bali, Indonesia. We distributed OFT in January-December 2018 to 813 MSM in Bali. Supervised testing was offered first, and unsupervised was only offered to an individual who declined supervised testing. Included participants were MSM who did not have a HIV test result in the last 6 months and declined referral to facility-based testing. Of 813 participants, 93% (765/813) chose supervised testing and 7% (57/813) unsupervised. The OFT result was reactive for 83 (10%), of whom 52/83 (63%) underwent confirmatory testing with 47/52 (90%) found HIV positive. Among confirmed positives, 43/47 (92%) were enrolled in HATI study cohort, of whom 39 (91%) started treatment. At six months follow up, 25/39 (64%) of those initiating treatment were still receiving it, and all had a suppressed viral load. There was an increase in the mean number of MSM tested for HIV by HATI study Bali sites per month, from 100 (95%CI: 85-112) before the intervention to 152 (95% CI: 130-172) during the intervention. Our findings show the potential utility of offering HIV oral fluid self-test kits to scale-up HIV testing in MSM.Trial registration: ClinicalTrials.gov identifier: NCT03429842.

Web-Based Multifaceted Approach for Community-Based HIV Self-Testing Among Female Sex Workers in Indonesia: Protocol for a Randomized Community Trial.

BACKGROUND: New HIV infections in Indonesia continue to be concentrated among key populations, including female sex workers (FSWs). However, increasing HIV testing among this subpopulation remains a challenge, necessitating exploration into alternative testing modalities. OBJECTIVE: This study aims to assess whether the addition of an oral fluid testing option in community settings would increase the rate of HIV case identification among FSWs. Because the study was implemented early in the outbreak of COVID-19 in Indonesia, a secondary objective is to assess approaches and tools for implementing both community outreach and community HIV screening for FSWs during pandemic conditions. METHODS: We undertook a community-based randomized trial in 23 national priority districts in which community outreach services were being provided. Community-based screening using an oral fluid-based rapid test was added to the community outreach standard of care in intervention districts with clients having the option of performing the test themselves or being assisted by outreach workers. A web-based system was created to screen for eligibility and collect participant data and test results, facilitating the process for both unassisted and assisted participants. Participants with reactive screening results were encouraged to undergo HIV testing at a health facility to confirm their diagnosis and initiate antiretroviral treatment as needed. Multiple means of recruitment were deployed including through outreach workers and social media campaigns. RESULTS: Of the 1907 FSWs who registered, met the eligibility criteria, and gave consent to participate, 1545 undertook community oral fluid test (OFT) screening. Most (1516/1545, 98.1%) opted for assisted screening. Recruitment via social media fell far short of expectations as many who registered independently for the OFT because of the social media campaign did not identify as FSWs. They were eventually not eligible to participate, but their interest points to the possibility of implementing HIV self-testing in the general population. The successful recruitment through outreach workers, facilitated by social media, indicates that their roles remain crucial in accessing FSW networks and improving HIV testing uptake. CONCLUSIONS: The addition of HIV self-testing to the standard of care supported by a web-based data collection system was able to increase HIV case identification among FSWs in intervention districts. The high satisfaction of OFT users and the interest of the general population toward this alternative testing modality are promising for scaling up community HIV screening nationally.

Why Counseling Intervention Fails to Improve Compliance towards Antiretroviral Therapy: Findings from a Mixed-Methods Study among People Living with HIV in Bali Province, Indonesia.

This study explores the contribution of counseling to improving acceptance of and adherence to anti-retroviral therapy (ART) among people living with HIV (PLHIV) and identifies key issues associated with its implementation. We conducted a longitudinal mixed-methods study in Bali Province between 2015 and 2017. The study participants were 170 newly diagnosed PLHIV and 17 outreach-counselor workers (OWs). We interviewed PLHIV for their experiences in receiving counseling, and acceptance of and adherence to ART. We surveyed four counseling domains (privacy, contents, frequency, and duration) and explored the key findings through in-depth interviews. In addition, 24 exit interviews and record reviews were performed. Quantitative data were analyzed descriptively, and qualitative data were analyzed thematically. Out of 170 PLHIV who received the counseling program, 139 (81.76%) accepted ART, and 52 (37.4%) discontinued ART in six months of follow up. Although counselors covered most of the content (16/17 components), the median time and frequency of counseling were insufficient. Despite a high score of HIV counseling provided to PLHIV in our study location, the overall acceptance of and adherence to ART remains fair or moderate. Our study suggests that counseling before ART initiation is inadequate for improving acceptance and adherence to ART in Bali Province. This reduced effectiveness is influenced by internal issues (interpersonal skills, limited technical capacity) and external factors both from PLHIV and society (stigma, disclosure, discrimination).

Getting Indonesia's HIV epidemic to zero? One size does not fit all.

Indonesia has one of the fastest growing HIV epidemics in the world. AIDS related deaths in Indonesia have not fallen and have increased significantly since 2010. HIV infection rates remain high and rising in key affected populations. We provide an on the ground, evidence-based perspective of the challenges Indonesia faces. We discuss what is required to adopt tailored public health approaches that address context specific challenges, confront structural barriers and the heterogeneity of the current evolving HIV epidemic.

Exposure to particulate matter (PM2.5) and prevalence of diabetes mellitus in Indonesia.

BACKGROUND: Recently emerging evidence suggests an association between particulate matter less than 2.5 µm in diameter (PM2.5) exposure and diabetes risk. However, evidence from Asia is limited. Here, we evaluated the association between PM2.5 exposure and the prevalence of diabetes mellitus in one of the most populated countries in Asia, Indonesia. METHODS: We used the 2013 Indonesia Basic Health Research, which surveyed households in 487 regencies/municipalities in all 33 provinces in Indonesia (n = 647,947). We assigned individual exposure to PM2.5 using QGIS software. Multilevel logistic regression with a random intercept based on village and cubic spline analysis were used to assess the association between PM2.5 exposure and the prevalence of diabetes mellitus. We also assessed the lower exposure at which PM2.5 has potential adverse effects. RESULTS: We included 647,947 subjects with a mean age of 41.9 years in our study. Exposure to PM2.5 levels was associated with a 10-unit increase in PM2.5 (fully adjusted odds ratio: 1.09; 95% confidence interval: 1.05-1.14). The findings were consistent for quartile increases in PM2.5 levels and the cubic spline function. Even when we restricted to those exposed to PM2.5 concentrations of less than 10.0 µg/m3 in accordance with the recommended guidelines for annual exposure to PM2.5 made by the World Health Organization, the association remained elevated, especially among subjects living in the urban areas. Hence, we were unable to establish a safe threshold for PM2.5 and the risk of diabetes. CONCLUSIONS: Our findings suggest a positive association between PM2.5 exposure and prevalence of diabetes mellitus, which is possibly below the current recommended guidelines. Further studies are needed to ascertain the causal association of this finding.

Evaluation of Community-Based Dog Welfare and Rabies Project in Sanur, a Sub-district of the Indonesian Island Province of Bali.

The Indonesian island province of Bali experienced its first rabies incursion in 2008. Mass vaccination of the dog population has proven effective and rabies cases in dogs and people have decreased, however the virus is still circulating among the dog population. Vaccination coverage must be maintained until rabies elimination. Increasing efficiency and effectiveness of vaccination campaigns is therefore desired. Community engagement leading to preventative health actions by community members can reduce disease incidence and costs of control. Here we evaluate 2 years of a novel community-based dog welfare and rabies control project (Program Dharma) in the Sanur sub-district. The project engaged the services of people living in the project area with an interest or experience in dogs or community health services. These people spoke with owners within their own community about dog welfare and health, monitored owned and unowned dogs and increased owner and carer efforts to access vaccination and further veterinary services. The evaluation focused on a sample of dogs whose owners had been regularly engaged with project. Vaccination coverage was increased and there were no dog or human rabies cases reported in the project area; the percentage of the dogs that had never been vaccinated was reduced by an average 28.3% (baseline unvaccinated 41-49%, post-project unvaccinated 11-19%). The welfare of dogs improved from an average of 20.7% of dogs with visible welfare problems at baseline to 2.7% after project implementation. Roaming dog density observed on street surveys also decreased in all project areas (24-47% reduction dependent on desa). A participatory evaluation event with a sample of Program Dharma community-based agents highlighted several additional successes, including that the community appeared to welcome and value their services and were beginning to support the cost of project activities. Conversely, challenges included identifying dogs in the database during revisits, sustaining the costs of community member time spent working on Program Dharma activities and the costs of veterinary care, whilst avoiding dependency of owners on free veterinary services. The benefits revealed by the evaluation were judged to be sufficient to extend Program Dharma to new areas, whilst evolving activities to resolve challenges.

HIV testing uptake among pregnant women attending private midwife clinics: challenges of scaling up universal HIV testing at the private sectors in Indonesia.

INTRODUCTION: Being ranked seventh among countries with the highest number of new pediatric HIV infection, around 3% of new pediatric HIV infection worldwide occurs in Indonesia. UNAIDS has set a goal of elimination of mother-to-child HIV transmission, and private sector plays a critical role in achieving this goal. More than half of pregnant women in Indonesia seek antenatal care (ANC) services at private sectors, particularly at private midwife clinics. However, no published data is available on the rates of HIV testing uptake among pregnant women at these clinics, reflecting important gap on prevention of mother to child HIV transmission programmatic data. PURPOSE: A longitudinal study was conducted to examine the rates of HIV testing uptake among pregnant women attending private midwife clinics in Bali and were referred to Voluntary HIV counselling and testing (VCT) clinics for a HIV test. METHODS: Seventy midwives from private clinics were asked to suggest women, who were deemed to be at risk of HIV, to seek HIV testing at the nominated VCT clinics and to provide the women with a referral. Data were then analyzed to identify the percentage of women who took HIV testing at the VCT clinics among those referred by the midwives. RESULTS: The midwives referred 619 women to VCT clinics. Of the referred women, only 321 (52%; 95% CI, 47.8%-55.9%) took a HIV test at the appointed clinics. Among these who tested, three (0.9%) were HIV positive. This study identified a challenge in scaling up HIV testing coverage among women seeking ANC services at private sectors. Implications and recommendations are discussed.

Economic burden of dengue in Indonesia.

BACKGROUND: Dengue is associated with significant economic expenditure and it is estimated that the Asia Pacific region accounts for >50% of the global cost. Indonesia has one of the world's highest dengue burdens; Aedes aegypti and Aedes albopictus are the primary and secondary vectors. In the absence of local data on disease cost, this study estimated the annual economic burden during 2015 of both hospitalized and ambulatory dengue cases in Indonesia. METHODS: Total 2015 dengue costs were calculated using both prospective and retrospective methods using data from public and private hospitals and health centres in three provinces: Yogyakarta, Bali and Jakarta. Direct costs were extracted from billing systems and claims; a patient survey captured indirect and out-of-pocket costs at discharge and 2 weeks later. Adjustments across sites based on similar clinical practices and healthcare landscapes were performed to fill gaps in cost estimates. The national burden of dengue was extrapolated from provincial data using data from the three sites and applying an empirically-derived epidemiological expansion factor. RESULTS: Total direct and indirect costs per dengue case assessed at Yogyakarta, Bali and Jakarta were US$791, US$1,241 and US$1,250, respectively. Total 2015 economic burden of dengue in Indonesia was estimated at US$381.15 million which comprised US$355.2 million for hospitalized and US$26.2 million for ambulatory care cases. CONCLUSION: Dengue imposes a substantial economic burden for Indonesian public payers and society. Complemented with an appropriate weighting method and by accounting for local specificities and practices, these data may support national level public health decision making for prevention/control of dengue in public health priority lists.

The cascade of HIV care among key populations in Indonesia: a prospective cohort study.

BACKGROUND: Indonesia has had low uptake of HIV testing and treatment. We did a study to estimate the cascade of HIV care in key populations and identify predictors of outcomes at key cascade steps. METHODS: We used an observational cohort study design to recruit and follow up men who have sex with men (MSM), female sex workers, transgender women (known as waria in Indonesia), and people who inject drugs (PWID) diagnosed with HIV in four locations in Indonesia: Bali, Bandung, Jakarta, and Yogyakarta. Recruitment, baseline, and follow-up visits were done at collaborating clinical services, including both primary care sites and hospitals. Inclusion criteria for participants included identifying as a member of a key population, age 16 years or older, not previously tested positive for HIV, and HIV positivity at baseline. All participants were offered treatment as per national guidelines, with the addition of viral load testing and completion of study-specific forms. Estimates were calculated of proportions of participants linked to care, commencing treatment, adherent to treatment, and who achieved virological suppression. We used logistic regression to investigate characteristics associated with antiretroviral therapy (ART) initiation and viral suppression and Cox regression to identify factors associated with loss to follow-up. This study is registered with ClinicalTrials.gov, NCT03429842. FINDINGS: Between Sept 15, 2015, and Sept 30, 2016, 831 individuals were enrolled in the study, comprising 637 (77%) MSM, 116 (14%) female sex workers, 27 (3%) waria, and 51 (6%) PWID. Of those enrolled, 703 (84·6%, 95% CI 82·1-87·1) were linked to HIV care and 606 (86·2%, 83·7-88·8) who were linked with care started ART. Among participants who started treatment, 457 (75·4%, 71·8-78·9) were retained in care, of whom 325 (71·1%, 66·7-75·2) had a viral load test about 6 months after enrolment, with 294 (90·5%, 86·7-93·4) of those tested (294 [35%, 32·1-38·7] of the original cohort) virally suppressed. 146 (24%) of 606 who started treatment were lost to follow-up. People who enrolled at sites that offered both testing and treatment had a higher likelihood of treatment initiation than those who enrolled at sites offering testing only (p<0·0001 by multivariate analysis), and participants who had been linked to care and had a high school or university education were significantly more likely to achieve viral suppression than those with a primary school or lower level of education (p≤0·029 by mulivariate analysis). INTERPRETATION: HIV cascade data among key populations in Indonesia show very poor rates of retention in treatment and viral suppression. Site and individual characteristics associated with initiating and continuing treatment suggest an urgent need to develop and implement effective interventions to support patients in achieving viral suppression among all people with HIV.

Dog Ecology and Rabies Knowledge of Owners and Non-Owners in Sanur, A Sub-District of the Indonesian Island Province of Bali.

This study gained an understanding of dog demographics, owner behaviour, and knowledge, attitudes and practices relating to rabies in three villages in Sanur, Bali, providing insights for an intervention to improve responsible dog ownership. A combination of a census of all dogs, street surveys of roaming dogs, and a Knowledge, Attitude and Practices (KAP) survey was used to study both dogs and people. A total of 6009 dogs were recorded, of which only 3.3% appeared to be unowned; unowned dogs had poorer welfare and were more likely to be wary of attempted approaches by people. The source of dogs, method of confinement used by owners, and whether dogs were sterilised differed between three breed types; purebred dogs, mixed breed, and Bali dogs (native breed). Three variables were found to have significant effects on the chances of not being vaccinated: age, dog type, and confinement. A mean of 3.81 roaming dogs per km of street surveyed was recorded along 28 sub-village routes. Responses to attitude statements showed that most people had a positive attitude towards dogs and vaccination and did not agree with culling. Knowledge of appropriate bite treatment and symptoms of rabies in dogs was good.

Mortality among people living with HIV on antiretroviral treatment in Bali, Indonesia: incidence and predictors.

Indonesia has the third highest number of people living with HIV/AIDS (PLWH) and the greatest increase in proportion of AIDS-related mortality in the Asia Pacific region between 2005 and 2013. Longitudinal mortality data among PLWH in Indonesia are limited. We conducted a retrospective cohort study from medical records of antiretroviral treatment (ART) recipients attending Badung General Hospital (BGH) and Bali Medica Clinic (BMC) between 2006 and 2014. We explored incidence of mortality by Kaplan-Meier analysis and identified predictors using a Cox proportional hazard model. In total, 575 patients were included in the analysis; the majority were male. The overall mortality rate was 10% per year. Multivariate analysis suggested that being male (adjusted hazard ratio [aHR]: 2.74; 95% confidence interval [CI]: 1.34-5.59), having a lower education (aHR: 2.17; 95%CI: 1.31-3.61), having heterosexual (aHR: 7.40; 95% CI: 2.61-21.00) or injecting drug use (aHR: 13.20; 95% CI: 3.17-55.00) as the likely transmission risk category, starting treatment with low CD4 cell counts (aHR: 3.18; 95% CI: 1.16-8.69), and not having a treatment supervisor (aHR: 4.02; 95% CI: 2.44-6.65) were independent predictors of mortality. The mortality was high, particularly in the first three months after initiating ART. These findings highlight the need to encourage HIV testing and early diagnosis and prompt treatment. Applying aspects of BMCs targeted HIV services model in more generalised services such as BGH may be beneficial. Providing adherence support as part of ART services is key to promoting adherence to ART.

Injecting drug use, sexual risk, HIV knowledge and harm reduction uptake in a large prison in Bali, Indonesia.

PURPOSE: The purpose of this paper is to describe HIV-related risk behavior and knowledge of HIV among inmates of Kerobokan prison Bali, Indonesia. DESIGN/METHODOLOGY/APPROACH: A cross-sectional survey of inmates of using a structured questionnaire and sample framework to reflect narcotic use among inmates and the prison gender mix. FINDINGS: Among 230 inmates recruited to the study self-reported prevalence of injecting drug use was 7.4 percent (95 percent CI 4.0-10.8 percent). Respondents who participated in a prison based methadone treatment program were all still injecting drugs, these made up 13/17 of the IDU. In total, 47 percent (95 percent CIs 45-55 percent) of respondents who reported injecting also reported sharing needles within the last week. Sexual intercourse while in prison was reported by 3.0 percent (95 percent CI 0.82-5.26 percent) of study respondents. One-third of non-injectors were unaware of the preventative role of condom use. This study suggests that despite harm reduction initiatives within Kerobokan prison HIV risk behavior continues and there is a considerable lack of awareness of the importance of condom use in preventing HIV. RESEARCH LIMITATIONS/IMPLICATIONS: The authors relied on self-reported risk behavior that may be subject to reporting bias. The sampling strategy may not reflect the true ratio inmates using or not using narcotics. PRACTICAL IMPLICATIONS: The current harm reduction approach, including methadone substitution treatment should be optimized within the Indonesian prison setting. ORIGINALITY/VALUE: This is the first study reporting HIV-related risk behavior from an Indonesian prison with an established methadone substitution program.

Clinical efficacy and safety of a novel tetravalent dengue vaccine in healthy children in Asia: a phase 3, randomised, observer-masked, placebo-controlled trial.

BACKGROUND: An estimated 100 million people have symptomatic dengue infection every year. This is the first report of a phase 3 vaccine efficacy trial of a candidate dengue vaccine. We aimed to assess the efficacy of the CYD dengue vaccine against symptomatic, virologically confirmed dengue in children. METHODS: We did an observer-masked, randomised controlled, multicentre, phase 3 trial in five countries in the Asia-Pacific region. Between June 3, and Dec 1, 2011, healthy children aged 2-14 years were randomly assigned (2:1), by computer-generated permuted blocks of six with an interactive voice or web response system, to receive three injections of a recombinant, live, attenuated, tetravalent dengue vaccine (CYD-TDV), or placebo, at months 0, 6, and 12. Randomisation was stratified by age and site. Participants were followed up until month 25. Trial staff responsible for the preparation and administration of injections were unmasked to group allocation, but were not included in the follow-up of the participants; allocation was concealed from the study sponsor, investigators, and parents and guardians. Our primary objective was to assess protective efficacy against symptomatic, virologically confirmed dengue, irrespective of disease severity or serotype, that took place more than 28 days after the third injection. The primary endpoint was for the lower bound of the 95% CI of vaccine efficacy to be greater than 25%. Analysis was by intention to treat and per procotol. This trial is registered with ClinicalTrials.gov, number NCT01373281. FINDINGS: We randomly assigned 10,275 children to receive either vaccine (n=6851) or placebo (n=3424), of whom 6710 (98%) and 3350 (98%), respectively, were included in the primary analysis. 250 cases of virologically confirmed dengue took place more than 28 days after the third injection (117 [47%] in the vaccine group and 133 [53%] in the control group). The primary endpoint was achieved with 56·5% (95% CI 43·8-66·4) efficacy. We recorded 647 serious adverse events (402 [62%] in the vaccine group and 245 [38%] in the control group). 54 (1%) children in the vaccine group and 33 (1%) of those in the control group had serious adverse events that happened within 28 days of vaccination. Serious adverse events were consistent with medical disorders in this age group and were mainly infections and injuries. INTERPRETATION: Our findings show that dengue vaccine is efficacious when given as three injections at months 0, 6, and 12 to children aged 2-14 years in endemic areas in Asia, and has a good safety profile. Vaccination could reduce the incidence of symptomatic infection and hospital admission and has the potential to provide an important public health benefit. FUNDING: Sanofi Pasteur.

Dengue and other common causes of acute febrile illness in Asia: an active surveillance study in children.

BACKGROUND: Common causes of acute febrile illness in tropical countries have similar symptoms, which often mimic those of dengue. Accurate clinical diagnosis can be difficult without laboratory confirmation and disease burden is generally under-reported. Accurate, population-based, laboratory-confirmed incidence data on dengue and other causes of acute fever in dengue-endemic Asian countries are needed. METHODS AND PRINCIPAL FINDINGS: This prospective, multicenter, active fever surveillance, cohort study was conducted in selected centers in Indonesia, Malaysia, Philippines, Thailand and Vietnam to determine the incidence density of acute febrile episodes (≥ 38 °C for ≥ 2 days) in 1,500 healthy children aged 2-14 years, followed for a mean 237 days. Causes of fever were assessed by testing acute and convalescent sera from febrile participants for dengue, chikungunya, hepatitis A, influenza A, leptospirosis, rickettsia, and Salmonella Typhi. Overall, 289 participants had acute fever, an incidence density of 33.6 per 100 person-years (95% CI: 30.0; 37.8); 57% were IgM-positive for at least one of these diseases. The most common causes of fever by IgM ELISA were chikungunya (in 35.0% of in febrile participants) and S. Typhi (in 29.4%). The overall incidence density of dengue per 100 person-years was 3.4 by nonstructural protein 1 (NS1) antigen positivity (95% CI: 2.4; 4.8) and 7.3 (95% CI: 5.7; 9.2) by serology. Dengue was diagnosed in 11.4% (95% CI: 8.0; 15.7) and 23.9% (95% CI: 19.1; 29.2) of febrile participants by NS1 positivity and serology, respectively. Of the febrile episodes not clinically diagnosed as dengue, 5.3% were dengue-positive by NS1 antigen testing and 16.0% were dengue-positive by serology. CONCLUSIONS: During the study period, the most common identified causes of pediatric acute febrile illness among the seven tested for were chikungunya, S. Typhi and dengue. Not all dengue cases were clinically diagnosed; laboratory confirmation is essential to refine disease burden estimates.

Preparing for introduction of a dengue vaccine: recommendations from the 1st Dengue v2V Asia-Pacific Meeting.

Infection with dengue virus is a major public health problem in the Asia-Pacific region and throughout tropical and sub-tropical regions of the world. Vaccination represents a major opportunity to control dengue and several candidate vaccines are in development. Experts in dengue and in vaccine introduction gathered for a two day meeting during which they examined the challenges inherent to the introduction of a dengue vaccine into the national immunisation programmes of countries of the Asia-Pacific. The aim was to develop a series of recommendations to reduce the delay between vaccine licensure and vaccine introduction. Major recommendations arising from the meeting included: ascertaining and publicising the full burden and cost of dengue; changing the perception of dengue in non-endemic countries to help generate global support for dengue vaccination; ensuring high quality active surveillance systems and diagnostics; and identifying sustainable sources of funding, both to support vaccine introduction and to maintain the vaccination programme. The attendees at the meeting were in agreement that with the introduction of an effective vaccine, dengue is a disease that could be controlled, and that in order to ensure a vaccine is introduced as rapidly as possible, there is a need to start preparing now.

Condom use among brothel-based sex workers and clients in Bali, Indonesia.

BACKGROUND: The objective of this paper is to describe the situation among Indonesian sex workers and clients in Bali, Indonesia, through a series of studies conducted during the 1990s. METHODS: Five surveys of sex workers and clients were conducted from 1992 through to 1999. RESULTS: The proportion of female sex workers who have heard about AIDS and condom use has increased tremendously in this area. In 1992-93, 51% of women reported ever hearing of AIDS and this had increased to 97% by 1999 (P < 0.01). Reported condom use with clients increased from 19% in 1992-93 to 78% in 1999 (P < 0.01). However, condom use is still far from 100% and perceived susceptibility towards HIV infection among female sex workers and their male clients remains low. Ineffective preventive strategies such as medication use remain common. HIV infection was very low in this population, although the prevalence of other sexually transmitted infections such as gonorrhea and chlamydia was very high. CONCLUSIONS: Educational interventions have been conducted with the sex workers, but the main source of education for clients has been through the media. Future programs need to develop more focused efforts to reach clients. These interventions may include worksite interventions, mass media campaigns, youth programs or other models.

Voluntary HIV testing, disclosure, and stigma among injection drug users in Bali, Indonesia.

Recently, large increases have been noted in injection drug use and HIV prevalence in Indonesia. Because voluntary HIV counseling and testing can play an important role in HIV prevention, it is important to understand factors related to its use. The objective of this study was to identify factors related to the use of voluntary HIV testing among drug users. In-depth interviews were conducted with a sample of 40 drug users in the Denpasar area of Bali, Indonesia. Drug users may be interested in testing if they have enough information about AIDS to know that they are at risk and that they need this information to protect themselves and others from infection. Barriers toward testing included the fear of a positive result, fear of reactions from family and community members and stigmatization. Other obstacles include a feeling of hopelessness, problems with testing, unavailability and side effects of AIDS drugs and other factors. Many persons would not disclose their status to community members and sexual partners. There were serious concerns about others being ashamed of them and the impact of HIV on relationships with spouses and sexual partners and on employment.

The Bali STD/AIDS study: human papillomavirus infection among female sex workers.

Female sex workers in low priced brothel areas in Denpasar, Bali, Indonesia participated in an intervention study designed to promote condom use and sexually transmitted disease (STD)/AIDS prevention. The intervention provided educational sessions for sex workers, STD treatment for sex workers, condom distribution, and media for clients. The brothel areas were divided into high and low areas for programme effort. The high effort areas received a more intensive behavioural intervention than the low effort areas. A clinic was available for STD treatment in both areas. Behavioural surveys and STD testing were used to evaluate the programmes. About 600 were evaluated for several STDs and completed personal interviews at enrolment and at six-month intervals during the 18-month study. About 50% of women were new to the study at each round. Human papillomavirus (HPV) testing of cervical swabbed specimens, using polymerase chain reaction methodology, was performed at the beginning of the study and 18 months later. Human papillomavirus infection was initially high in these women (38.3%) and declined to 29.7% after 18 months (P <0.01). The prevalence of HPV infection declined with age (P <0.01). HPV infection was associated with a number of STD symptoms that were reported in personal interviews. These associations were stronger in the first time period. Infection with Neisseria gonorrhoeae was associated with HPV infection at baseline (P =0.03). HPV infection declined in the study area with the more intensive educational programme (P <0.01). The prevalence of HPV infection declined over time and was associated with study area and age of woman.
