10-year risk for cardiovascular diseases according to the WHO prediction chart: findings from the National Health and Morbidity Survey (NHMS) 2019

BackgroundThere has been a significant increase in the incidence of cardiovascular disease (CVD) in Malaysia. It is important to identify the group at high risk of CVD. This study aimed to assess the population distribution and factors associated with 10-year CVD risk among adults aged 40 to 74 years in Malaysia.MethodsThis study used secondary data from the NHMS 2019, a nationally representative cross-sectional population study. The following measurements were collected: anthropometric, systolic blood pressure, fasting blood glucose, total cholesterol, smoking, and sociodemographic. The 2019 WHO Southeast Asia laboratory-based charts were used to estimate individuals’ CVD risk. These charts predict significant cardiovascular events over ten years. Multiple logistic regression analysis was employed to ascertain the factors that are linked to elevated or extremely elevated risk of CVD.ResultsA total of 5,503 respondents were included in the analysis. Less than one-quarter of the respondents were current smokers and obese. Approximately 41.7%, 30.9%, and 22.5% of the participants had extremely low risk (less than 5%), low risk (between 5% and less than 10%), and moderate risk (between 10% and less than 20%), respectively. A total of 4.9% of the participants were categorised as having high (20% to < 30%) or very high (CVD) risk (≥ 30%). This classification was more prevalent among males (7.3%) than among females (2.5%; p < 0.001). The factors associated with high/very high CVD risk were unemployment (aOR = 1.88, 95% CI = 1.47–2.40), those with non-formal and primary education level (aOR = 2.36, 95% CI = 1.36 − 4.12 and aOR = 3.28, 95% CI = 2.10 − 5.12, respectively), and being physically inactive with obesity (aOR = 2.19, 95% CI = 1.18 − 4.08).ConclusionsThis study revealed that almost 5% of the population in Malaysia has a high 10-year CVD risk. These findings highlight Malaysia’s urgent need for comprehensive CVD prevention efforts.

How to Make Future Cities Smart in the Realm of Environmentally Friendly Healthy Cities? Looking from the Perspective of Ease of Living Index

Rapid urbanization and environmental issues have led the Government of India to implement urban development initiatives like Heritage City Development and Augmentation Yojana, Atal Mission for Rejuvenation and Urban Transformation, Smart Cities Mission, Deen Dayal Antyodaya Yojana-National Urban Livelihood Mission, and Swachh Bharat Mission-Urban to improve citizens' quality of life. The Ease of Living Index (EOL), developed to assess the outcomes of these initiatives, is a data-driven assessment tool aligned with the Sustainable Development Goals that enables cities to adopt evidence-based planning and execution. It assesses the well-being of citizens in 111 cities, including cities under the Smart Cities Mission, capital cities, and cities with populations over one million. The concept of healthy cities gained popularity in the South-east Asian Region of the World Health Organization, with the Healthy City Network Assessment Tool being introduced in 2021 to help cities assess their health profile in its eleven member countries, including India. In view of NITI Aayog's 2021 recommendation for the development of 500 healthy cities by 2030, there is a need to expand the scope of the existing EOL Index (2020). This research aims to integrate the healthy city evaluation criteria from WHO's South-east Asia Regional Guidelines with the EOL Index 2020 to develop an integrated tool for data-driven assessment of India's proposed healthy cities program. The study based on literature review and comparative analysis identifies 8 determinants, 28 sub-determinants and 112 indicators, enhancing the comprehensiveness of the EOL Index to promote smart, environmentally friendly, healthy, and sustainable urban development.

Evaluation of Vulnerabilities for the Spread of Carbapenem Resistant Organisms at Five Hospitals in India

Background: The 2022 WHO global survey on infection prevention and control (IPC) exposes significant gaps in IPC in the WHO Southeast Asia region. A better understanding of IPC vulnerabilities will inform improvement initiatives. We describe an evaluation of IPC practices known to prevent and contain carbapenem-resistant organisms (CROs) at hospitals participating in the United States Centers for Disease Control Global Action in Healthcare Network –Antimicrobial Resistance in India. Prior hospital evaluations suggest resistance to carbapenems among gram-negative isolates is up to 45%. Methods: We conducted a mixed methods evaluation including cross-sectional surveys, semi-structured interviews, and site observations at five hospitals (one government, two private tertiary care, and two private teaching) located in three cities. The number of hospital beds ranged from 362 to 2,011. Hospital and IPC program characteristics, and CRO prevention and containment activities were examined virtually. Site observations focused on hand hygiene, environmental cleaning, personal protective equipment (PPE), CRO containment practices and use of water for patient care. Results: All sites had IPC programs with established policies and qualified IPC staff. The IPC nurse-to-bed ratio ranged from 1:73 to 1:432 (mean, 1:209). Due to the integral role of microbiology staff in IPC at these hospitals, the two departments had strong communication channels associated with CRO identification. Screening for CRO colonization, if done, targeted patients from outside hospitals. Three of the five hospitals routinely implemented contact precautions for patients with identified CROs, displayed isolation signage at the bedside, and provided adequate PPE at point-of-use; however, all sites reported barriers to effective isolation and/or cohorting patients with CROs. Timely communication of CROs to clinical staff varied and no sites effectively relayed CRO status upon patient discharge to another facility. IPC teams identified gaps in environmental cleaning procedures and practices related to medical devices and equipment. All sites used alternatives to tap water for clinical care and sink etiquette was evident. Each IPC team performed audits of patient isolation and hand hygiene practices. Despite the considerable proportion of IPC resources dedicated to daily education and feedback in clinical areas, the IPC teams reported that improvement was often difficult to achieve. Conclusion: Given the high burden of CROs and limited IPC resources, detailed knowledge of IPC opportunities for improvement will help hospitals target novel interventions for CRO prevention and containment. Further investigation of colonization rates and effective performance improvement methods in these settings is needed.Disclosure: Patricia Simner: Research Contracts: BD Diagnostics, OpGen Inc., Qiagen Sciences Inc, T2 Diagnostics, Accelerate Diagnostics; Research Collaborators:Ares Genetics, CosmosID, IDbyDNA, Illumina; Consulting: OpGen Inc., BD Diagnostics, Shionogi Inc., GeneCapture, Qiagen Sciences Inc, Entasis, Day Zero Diagnostics, Next Gen Diagnostics

Knowledge, compliance, and challenges in anti-malarial products usage: a systematic review of at-risk communities for zoonotic malaria

BackgroundZoonotic malaria is a growing public health threat in the WHO Southeast Asia (SEA) and Western Pacific (WP) regions. Despite vector-control measures, the distribution of Macaque fascicularis and M. nemestrina, and Anopheles mosquitoes carrying non-human simian malaria parasites poses challenges to malaria elimination. The systematic review assesses the literature on knowledge and malaria-preventive practices in zoonotic malaria-affected areas across the WHO SEA and WP, aiming to identify challenges for malaria control.MethodsPeer-reviewed articles published in English, Malay and Indonesian between January 2010 and December 2022 were searched in OVID Medline, Scopus, Web of Science, and Google Scholar. Studies of any design—excluding reviews, conference proceedings, and reports from all WHO SEA and WP countries vulnerable to zoonotic malaria—were included. Backwards-reference screening and thematic analysis were conducted.ResultsAmong 4,174 initially searched articles, 22 peer-reviewed articles met the inclusion criteria. An additional seven articles were identified through backwards-reference screening, resulting in a total of 29 articles for this review. Half of these studies were conducted in Cambodia, Myanmar, Malaysia, and Thailand, mainly in forests and remote communities. The review highlighted inconsistencies in the operationalization of knowledge, and five major themes were identified related to knowledge: causation and transmission, symptoms, treatment, severity and complications, and malaria prevention. While participants generally had some understanding of malaria causation/transmission, minority and indigenous ethnic groups demonstrated limited knowledge and held misconceptions, such as attributing malaria to drinking dirty water. Preventive practices included traditional and non-traditional or modern methods—with a preference for traditional approaches to avoid mosquito bites. Challenges to malaria control included feasibility, cost, and access to healthcare services.ConclusionThis review provides insights into knowledge, local understandings, and preventive practices related to malaria in the WHO SEA and WP regions. The findings highlight the need for future research to explore the knowledge of at-risk communities regarding zoonotic malaria, their perceive threat of the disease and factors exposing them to zoonotic malaria. New strategies must be developed for zoonotic malaria programs tailored to local contexts, emphasizing the significance of community participation, health education, and socio-behavioural change initiatives. It is important to consider the interconnectedness of human health, environmental and non-human primates conservation. Socio-cultural nuances should also be carefully considered in the design and implementation of these programs to ensure their effect tailored to local contexts.

Outbreak response capacity of the Global Outbreak Alert and Response Network across WHO's South-East Asia and Western Pacific regions.

The COVID-19 pandemic challenged the Global Outbreak Alert and Response Network's (GOARN) mechanism used to rapidly deploy technical support for international responses and highlighted areas that require strengthened capacity within the Network. GOARN's partners in the World Health Organization's (WHO) South-East Asia and Western Pacific regions were engaged to explore their levels of preparedness, readiness and ability to respond to international public health emergencies. Consultative discussions were held and a survey was conducted with GOARN's partners from the two WHO regions. Discussion topics included partners' capacity to support and participate in a GOARN deployment, training, research and collaboration. Descriptive and content analyses were conducted. Barriers to engaging in GOARN's international outbreak response efforts included limited numbers of personnel trained to respond to outbreaks; institutional, financial and administrative hurdles; and limited collaboration opportunities. Partners identified innovative solutions that could strengthen their engagement with deployment, such as financial subsidies, mentorship for less experienced staff, and the ability to provide remote support. GOARN plays an important role in enabling WHO to fulfil its international alert and response duties during disease outbreaks and humanitarian crises that have the potential to spark disease outbreaks. Yet without systematic improvement to strengthen national outbreak capacity and regional connectedness, support for international outbreak responses may remain limited. Thus, it is necessary to integrate novel approaches to support international deployments, as identified in this study.

Mapping the global neurosurgery workforce. Part 1: Consultant neurosurgeon density.

It is unknown whether efforts to expand access to neurosurgery worldwide have translated to an increase in the global neurosurgery workforce, particularly in low- and middle-income countries. The main objective of this study was to quantify the number and distribution of consultant neurosurgeons worldwide, while also identifying temporal and geographic trends in the neurosurgery workforce in different income levels and WHO regions, and analyzing what factors might contribute to the growth of a national workforce. This study was a subanalysis of an electronic cross-sectional survey administered to participants identified through neurosurgery societies, personal contacts, and online searches of all 193 countries and 26 territories, independent states, and disputed regions as defined by the World Bank (WB) and United Nations between October 2022 and March 2023. Population-weighted statistics for the consultant neurosurgery workforce and resource availability were estimated, and linear regression analysis was conducted to identify correlations with growth in the workforce. Data were obtained for 192 countries (99.5%) and 25 additional territories, states, and disputed regions (96.2%). One hundred seventy-seven respondents participated in the survey. There were an estimated 72,967 neurosurgeons worldwide, representing a global pooled density of 0.93 neurosurgeons per 100,000 people and a median country density of 0.44 neurosurgeons per 100,000 people. The authors found an increasing density of consultant neurosurgeons, from low-income countries (0.12 per 100,000 people), to lower-middle-income countries (LoMICs; 0.37), to upper-middle-income countries (UpMICs; 1.13), and to high-income countries (2.44). The WHO African and Southeast Asia regions had the lowest pooled neurosurgeon density, while the Western Pacific region (WPR) had the highest density. There were 29 countries, 14 territories, and 1 independent state with no neurosurgeons. Neurosurgeons in countries with higher income-level designations had more frequent access to resources and equipment. The annual growth rates in workforce density were highest in LoMICs (26.0%) and UpMICs (21.3%), and the most rapid annual growth was in the Southeast Asia region (33.0%). Regression analysis revealed that an increasing population quartile, the Eastern Mediterranean region (relative to the WPR), the presence of a national neurosurgery society, increasing global development aid, and national gross domestic product were associated with relative growth in national neurosurgeon density. The authors estimate a global consultant neurosurgeon workforce of nearly 73,000 neurosurgeons, with stark disparities in the density and growth of the workforce in different WB income-level groups and WHO regions. The presence of a neurosurgery society was correlated with the growth of the workforce, and this study identified several regional targets for further intervention to expand access to neurosurgery.

Report on the seventh meeting of national control laboratories for vaccines and biologicals of the WHO Western Pacific and South-East Asia member states

The Biregional Network of National Control Laboratories (NCLs) of the WHO Western Pacific and South-East Asia Regions has been meeting annually since 2018 to enhance NCLs' voluntary participation capacity. Its seventh meeting was hosted by the Korea National Institute of Food and Drug Safety Evaluation (NIFDS) of the Ministry of Food and Drug Safety (MFDS), in conjunction with the Global Bio Conference, in Seoul on September 6, 2022. Over 60 participants from seven countries, (India, Indonesia, Japan, Korea, Malaysia, the Philippines, and Vietnam) attended the meeting on-site and online. The theme of this meeting was ‘Quality Control Issues and International Trends for Biologicals including Vaccines and Plasma-Derived Medicinal Products.’ Three special speeches were presented on sharing the quality control system for biologicals, including NCLs' considerations in preparing the WHO Listed Authorities and sharing MFDS experiences. Furthermore, the participating NCLs shared country-specific issues related to national lot releases during the COVID-19 pandemic and acknowledged the meeting’s crucial role in response preparedness for pandemic emergencies and enhancing regulatory capacity through coalitions and information exchange among NCLs. The NIFDS will cooperate closely with other Asian NCLs to enhance biological product quality control, aiming to establish regional standards and standardize test methods through collaboration.

Profiling ultra-processed foods in Thailand: sales trend, consumer expenditure and nutritional quality

BackgroundUltra-processed foods (UPF) are associated with adverse health outcomes. This study aimed to analyse the national trends in retail sales, consumer expenditure and nutritional quality of UPFs in Thailand.MethodsThe study used data from the Euromonitor Passport database for analysis of retail sales and consumer expenditure, and from the Mintel Global New Products Database for nutritional analysis using the WHO Southeast Asian Region nutrient profile model.ResultsThe study found the highest per capita sales volume and value of UPFs in 2021 were sauces, dressings & condiments (8.4 kg/capita) and carbonated soft drinks (27.1 L/capita), respectively. However, functional & flavoured water, ready-made meals and baked goods had the highest observed (2012–2021) and expected (2021–2026) sales growth. Supermarkets were responsible for most of the UPF sales since 2012, but convenience stores had larger growth in retail values. Growth in consumer expenditure per capita on UPFs from 2012 to 2020, ranged between 12.7% and 34%, and till 2026 is forecast to grow between 26% and 30%. More than half of UPFs exceeded at least one nutrient cutoff, 59.3% for total fats, 24.8% for saturated fats, 68.2% for total sugars and 94.3% for sodium.ConclusionsThe findings suggest a need for regulatory and non-regulatory measures such as UPF taxation and marketing restrictions, and market incentives for producing non-UPFs. A system for regularly monitoring and evaluating healthiness (both nutritional and processing aspects) of food products, especially UPFs, is required.

Factors Related to the Incidence of Congenital Rubella Syndrome (CRS) in Indonesia

Congenital Rubella Syndrome (CRS) is a serious consequence in infants due to Rubella virus infection during early pregnancy which can cause several congenital abnormalities. In 2021, Indonesia became the country that reported the highest cases of CRS in the WHO Southeast Asia region with 229 cases out of a total of 402 cases (57%). There are various factors related to the incidence of CRS including vaccination, health facilities and mother and baby factors. Knowledge on these factors can be applied to improve efforts to prevent and control CRS cases. This study aims to determine the factors related to the incidence of CRS in Indonesia. This was a case-control study using secondary data derived from the 2020-2021 CRS sentinel surveillance reports of the Ministry of Health of the Republic of Indonesia. Based on the results of multivariate analysis using multiple logistic regression, it was revealed that there was one factor related to the incidence of CRS, namely the area of residence with an OR of 2.3 (95% CI: 1.49-3.42). The area of residence outside Java-Bali had a higher risk for the incidence of CRS by 2.3 times compared to the area of residence in Java-Bali. In contrast, other variables such as history of maternal vaccination, history of maternal Rubella infection, maternal age and the child gender were not found to be statistically related to the incidence of CRS. It can be concluded that the area of residence outside Java-Bali was a factor related to the incidence of CRS. Therefore, it is necessary to have an even distribution of Rubella vaccination coverage, strengthen the surveillance system and prepare equal distribution of health facilities to prevent the spread of Rubella cases.

Antibiotic concentrations and antibiotic resistance in aquatic environments of the WHO Western Pacific and South-East Asia regions: a systematic review and probabilistic environmental hazard assessment

Antibiotic resistance poses human health risks, and there are concerns about the effect of environmental antibiotic residues in the selection and spread of antibiotic resistance. The aim of this study was to identify antibiotic residue levels that are likely to select for resistance and relative contributions from different aquatic sources, of various aquatic environmental compartments of the WHO Western Pacific region (WPR) and the WHO South-East Asia region (SEAR), including in China and India. A systematic review of empirical studies that measured antibiotic concentrations in aquatic environments, published between 2006 and 2019, and a probabilistic environmental hazard assessments approach, were used to identify antibiotic concentrations that are likely to select for resistance in various aquatic environmental compartments of the WPR and SEAR, including in China and India. The assessment involved the use of measured environmental concentrations and predicted no-effect concentrations (PNECs). The systematic review found 218 relevant studies of 5230 screened from the WPR and 22 relevant studies of 2625 screened from the SEAR; some of these relevant studies were largely from China (n=168) and India (n=15). 92 antibiotics in the WPR and 45 in the SEAR were detected in various aquatic compartments. Antibiotic concentrations that most likely exceeded PNECs (0-100%) were observed in wastewater, and influents and effluents of wastewater treatment plants. Antibiotic concentrations that most likely exceeded PNECs were also observed in aquatic environmental compartments. The highest risk for the development of resistance was in tap or drinking water of the WPR and China for ciprofloxacin (62·5%). The relative contributions of potential sources of antibiotic contamination in waterways, such as hospitals, municipals, livestock, and pharmaceutical manufacturing, was determined for each antibiotic. The concentrations of antibiotic residues found in wastewater and wastewater treatment plants of the WPR and SEAR make them potential hotspots for the development of antibiotic resistance, which creates human health risks from environmental exposure via drinking water. These findings can help decision makers to target risk reduction measures against environmental residues of priority antibiotics in high-risk sites, and help to focus research efforts in these world regions.

What factors influence adherence and non-adherence to multi-drug therapy for the treatment of leprosy within the World Health Organisation South East Asia region? A systematic review

Introduction Leprosy is an infection caused by Mycobacterium leprae. Despite curative treatment being available, leprosy is still prevalent worldwide, with little change in annual cases observed in the past decade. The WHO South East Asia region is the worst affected, accounting for over 70% of new cases. One reason leprosy transmission still occurs is non-adherence to multi-drug therapy. This project aims to determine the factors that influence adherence. Methods A systematic review was performed using 6 databases. This returned 402 unique results. Screening of the title and abstract resulted in 362 of these being excluded. From the remaining 40, full-text analysis identified 17 studies that met the inclusion criteria and formed the review. Both qualitative and quantitative methods of collecting and analyzing data were used to form a non-quantitative synthesis of the findings. Results Four factors influenced adherence: medication-related, healthcare-related, patient-related and society-related. From these, lack of knowledge about leprosy and multi-drug therapy was a predominant barrier to adherence, which related to all of these factors. Stigma and being female were also seen as important barriers to adherence - these manifested in numerous ways. Conclusion The review identified diverse barriers to adherence to MDT and no simple intervention will overcome these. Rather, wider issues such as continuous access to healthcare (particularly for women), stigma reduction and patient education need to be addressed. Improving these will increase patient confidence in, and access to, MDT, which will ultimately result in improved adherence to therapy.

The impact of COVID-19 on essential health service provision for noncommunicable diseases in the South-East Asia region: A systematic review.

SummaryBackgroundCOVID-19 has had a profound impact on the health systems of the 11 countries of the WHO South East Asia Region. We conducted a systematic review of studies that used quantitative and comparative approaches to assess the impact of the pandemic on the service provision of four noncommunicable diseases (NCDs) (cancer, cardiovascular disease, chronic respiratory diseases, and diabetes) in the region.MethodsA systematic search was conducted in PubMed, Embase, MedRxiv, and WHO COVID-19 databases in December 2021. The quality of studies was evaluated using the Joanna Briggs Institute Critical Appraisal Checklist and the ROBINS-I risk of bias tool. A narrative synthesis was conducted following the ‘synthesis without meta-analysis’ reporting guidelines.FindingsTwo review authors independently screened 5,397 records with 31 studies included, 26 which were cross-sectional studies. Most studies (n=24, 77%) were conducted in India and 19 (61%) were single-site studies. Compared to a pre-pandemic period, 10/17 cancer studies found a >40% reduction in outpatient services, 9/14 cardiovascular disease found a reduction of 30% or greater in inpatient admissions and 2 studies found diagnoses and interventions for respiratory diseases reduced up to 78.9% and 83.0%, respectively. No eligible studies on the impact of COVID-19 on diabetes services were found.InterpretationCOVID-19 has substantially disrupted the provision of essential health services for NCDs in the WHO South East Asia Region, particularly cancer and cardiovascular disease. This is likely to have serious and potentially long-term downstream impacts on health and mortality of those living with or at risk of NCDs in the region.FundingThis work was supported by the WHO Sri Lanka Country Office.

Training and education in Digital Psychiatry: a perspective from Asia-Pacific Region

Introduction Digital mental health interventions and digital psychiatry have been rapidly implemented over the past decade, particularly with the intent to offer a cost-effective solution in those circumstances in which the current mental health services and infrastructure are not able to properly accommodate the patients’ needs. However, mental health workforce is often poorly theoretical/practical trained in digital psychiatry and in delivering remote consultations safely and effectively, not being common to own curricula-specific training requirements in digital psychiatry and skills.ObjectivesOur aim is evaluating the level of training, knowledge, experience and perception regarding the topic of digital psychiatry in a sample constituted by medical students, psychiatry trainees and early career psychiatrists from WHO South-East Asia and Western Pacific Regions (APAC).Methods A web-based international cross-sectional survey was carried out to specifically investigating digita psychiatry in APAC regions.Results An overall lack of theoretical and/or practical training on new digital tools and digital health interventions in psychiatry has been observed. The level of training influences knowledge background, which, in turn, influences young professionals’ perceptions and opinions regarding digital psychiatry and interventions in mental health.ConclusionsImplementing psychiatry training programs may significantly improve the level of knowledge and use of digital tools in mental healthcare. Moreover, mental health services and infrastructures should be properly adapted to the digital era, considering the overall weak and heterogeneous technical support and equipment, issues of internet connectivity and other administrative related challenges observed in APAC.DisclosureNo significant relationships.

Antimicrobial Resistance Research Collaborations in Asia: Challenges and Opportunities to Equitable Partnerships.

Antimicrobial Resistance is recognized as a major threat to global health security. The WHO Southeast Asia region is dubbed a “global hub for AMR emergence”, as it runs the highest risk for AMR emergence among all WHO regions in Asia. Hence, there is a need for Asia-centric, collaborative AMR research aligned with the true needs and priorities of the region. This study aimed to identify and understand the challenges and opportunities for such collaborative endeavors to enhance equitable partnerships. This qualitative study adopted an interpretative approach involving a thematic analysis of 15 semi-structured interviews with AMR experts conducting research in the region. The study identified several factors influencing research collaborations, such as the multi-dimensional nature of AMR, limited or lack of funds, different AMR research priorities in Asian countries, absence of Asia-centric AMR leadership, lack of trust and, unequal power relationships between researchers, and the negative impact of the COVID-19 pandemic in research collaborations. It also identified some opportunities, such as the willingness of researchers to collaborate, the formation of a few networks, and the prioritization by many academics of the One Health paradigm for framing AMR research. Participants reported that the initiation of stronger cross-discipline and cross-country networks, the development of Asia-centric AMR leadership, flexible research agendas with shared priorities, transparent and transferable funds, and support to enhance research capacity in LMICs could assist in developing more equitable collaborative research in Asia.

Seroprevalence and burden of hepatitis C virus infection in WHO South-East Asia Region: A systematic review.

This systematic review was aimed to estimate hepatitis C virus (HCV) seroprevalence and burden in disease in WHO South East Asia Region (SEAR). Electronic databases (PubMed, Scopus, Embase, and Google Scholar) and websites of non-indexed national medical journals, government and international health agencies were searched to identify English language literature published between 1991 and June 2020. We selected the studies reporting HCV seroprevalence in asymptomatic general (low-risk) and high-risk adult populations, that is, persons living with HIV (PLHIV), persons who inject drugs (PWID), sex workers, persons on maintenance hemodialysis (MHD), people in prison, and men sex with men (MSM). Seroprevalence data were combined to estimate weighted pooled prevalence (95% confidence interval) in each group and in each country, using the random-effects model. Estimated pooled seroprevalences were multiplied with estimated populations at risk to estimate the overall HCV burden. The analysis included 538 studies (35 Bangladesh, 6 Bhutan, 2 DPR Korea, 323 India, 43 Indonesia, 2 Maldives, 18 Myanmar, 29 Nepal, 11 Sri Lanka, 67 Thailand, and 2 Timor-Leste). In SEAR, the weighted pooled anti-HCV seroprevalence was estimated as 0.84% (0.56-1.12) in low-risk population and 13.67% (10.95-16.40) in PLHIV, 51.44% (43.67-59.20) in PWID, 25.80% (20.34-32.09) in MHD, 8.39% (5.84-11.51) in prison inmates, 2.69% (1.43-4.13) in people with high-risk sex behavior, and 11.43% (8.61-14.74) in MSM. The total HCV burden in low-risk and high-risk populations in SEAR countries was estimated as 12.45 million and 1.65 million, respectively. Our estimates of HCV seroprevalence and burden should help the respective countries in planning their HCV elimination strategies.
