RESUMEN
BACKGROUND: After the legalization of abortion in Nepal, there has been remarkable changes in policies and service delivery. However, even after two decades of legalization, access to and use of safe abortion services remains limited. The objective of this study is to estimate the incidence of abortion and unintended pregnancies in Nepal. METHODS: A cross sectional study was conducted in 767 health facilities using structured questionnaires to assess the availability of abortion services, and 231 key informant interviews were conducted. Information on medical abortion drugs was collected from distributors and pharmacies. Abortion estimations were segmented into categories: those performed within healthcare facilities, those conducted outside healthcare facilities, and those using other traditional methods. To estimate pregnancy outcomes, we utilized secondary data from national censuses and health surveys. RESULTS: The total incidence of induced abortion cases in Nepal was estimated to be 333,343 for the year 2021. Only 48 percent of abortion services were provided from the listed (legal) sites and providers. The estimates showed that total facility based induced abortion in Nepal was 176,216 in 2021, more than half were medical abortions. The highest and lowest abortion cases were in Bagmati and Karnali province respectively. The result showed that more than half of the pregnancies were unintended (53.3%). CONCLUSIONS: Despite a relatively liberal legal environment, more than half of all abortions are extra-legal in Nepal. Unintended pregnancies are also common, resulting in induced abortion. This demands for increasing access to information and services on contraception and safe abortion among women and girls.

BACKGROUND: Health service readiness is a prerequisite to accessing quality services. This study analyzes the readiness of health facilities in Nepal to provide comprehensive abortion services by focusing on the availability and quality of care.⯠Methods: This is a cross-sectional study, and a multi-stage sampling approach was used to select health facilities. A total of 767 health facilities were surveyed from 30 Municipalities across the country. Results: In a study of 767 health facilities surveyed, only 223 (29%) offered abortion services. Among them, 92% offered medical abortion, 48% provided manual vacuum aspiration, 18% offered dilation and evacuation and 18% offered medical induction. Approximately 7% of health facilities lacked trained providers yet still provided services and 29% of health facilities providing abortion services were not compliant with legal requirements. Interestingly, 13% of these facilities lacked short-acting contraceptives. Conclusions: Most health facilities in Nepal lack readiness for Safe Abortion Services (SAS), failing to meet minimum criteria, including to provide abortion legally. Urgent collaborative efforts among policymakers, administrators, and healthcare providers are needed to align with Nepal's Sustainable Development Goals and address gaps in safe abortion service availability. This includes policy updates, strengthening Public-Private Partnerships (PPPs), and ensuring comprehensive SAS implementation and financing as part of essential health services.

BACKGROUND: Abortion was legalized by the 2002 Muluki Ain to combat the surging rates of maternal mortality and morbidity. By 2021, the Maternal Mortality Rate plummeted to 151 from 539 in 1996. The decline in the abortion-related maternal mortality attributes to the implication of progressive abortion policies that includes expanded safe abortion services introduction of medical abortion, constitutional recognition of abortion, the mandates by Safe Motherhood and Reproductive Health Rights Act, and free-of-cost abortion services in government health facilities. This review study delves into exploring the contemporary abortion policies and its implications on women's access to safe abortion services as well as the factors that affect the access. METHODS: This study incorporates findings from extensive desk review of abortion services in Nepal. RESULTS: The 2021 safe abortion services Program Implementation Guideline aims to expand safe abortion sites; however, the Nepal's challenging geography ensues its inequitable distribution, especially in mountainous area. Policy provisions on information and financial accessibility to abortion are well navigated by the Safe Motherhood and Reproductive Health Rights Act and regulation but consistent to sporadic gaps in its implementation were comprehended in this study. This paper further discussed the Safe Motherhood and Reproductive Health Rights Act's regressive mandate of 28-week gestational limit at any condition and the role of gender in abortion decision-making under the pretext of factors influencing safe abortion services. CONCLUSIONS: The review study recommends strategies: improving capacity for abortion services under federalism, combating stigma, improving the private sector's readiness, and building a resilient health system.

INTRODUCTION: Maternal mortality in Nepal dropped from 553 to 186 per 100 000 live births during 2000-2017 (66% decline). Neonatal mortality dropped from 40 to 21 per 1000 live births during 2000-2018 (48% decline). Stillbirths dropped from 28 to 18 per 1000 births during 2000-2019 (34% decline). Nepal outperformed other countries in these mortality improvements when adjusted for economic growth, making Nepal a 'success'. Our study describes mechanisms which contributed to these achievements. METHODS: A mixed-method case study was used to identify drivers of mortality decline. Methods used included a literature review, key-informant interviews, focus-group discussions, secondary analysis of datasets, and validation workshops. RESULTS: Despite geographical challenges and periods of political instability, Nepal massively increased the percentage of women delivering in health facilities with skilled birth attendance between 2000 and 2019. Although challenges remain, there was also evidence in improved quality and equity-of-access to antenatal care and childbirth services. The study found policymaking and implementation processes were adaptive, evidence-informed, made use of data and research, and involved participants inside and outside government. There was a consistent focus on reducing inequalities. CONCLUSION: Policies and programmes Nepal implemented between 2000 and 2020 to improve maternal and newborn health outcomes were not unique. In this paper, we argue that Nepal was able to move rapidly from stage 2 to stage 3 in the mortality transition framework not because of what they did, but how they did it. Despite its achievements, Nepal still faces many challenges in ensuring equal access to quality-care for all women and newborns.

In Nepal, visceral leishmaniasis (VL) has been targeted for elimination as a public health problem by 2026. Recently, increasing numbers of VL cases have been reported from districts of doubtful endemicity including hills and mountains, threatening the ongoing VL elimination program in Nepal. We conducted a multi-disciplinary, descriptive cross-sectional survey to assess the local transmission of Leishmania donovani in seven such districts situated at altitudes of up to 1,764 meters in western Nepal from March to December 2019. House-to-house surveys were performed for socio-demographic data and data on past and current VL cases. Venous blood was collected from all consenting individuals aged ≥2 years and tested with the rK39 RDT. Blood samples were also tested with direct agglutination test, and a titer of ≥1:1600 was taken as a marker of infection. A Leishmania donovani species-specific PCR (SSU-rDNA) was performed for parasite species confirmation. We also captured sand flies using CDC light traps and mouth aspirators. The house-to-house surveys documented 28 past and six new VL cases of which 82% (28/34) were without travel exposure. Overall, 4.1% (54/1320) of healthy participants tested positive for L. donovani on at least one serological or molecular test. Among asymptomatic individuals, 17% (9/54) were household contacts of past VL cases, compared to 0.5% (6/1266) among non-infected individuals. Phlebotomus argentipes, the vector of L. donovani, was found in all districts except in Bajura. L. donovani was confirmed in two asymptomatic individuals and one pool of sand flies of Phlebotomus (Adlerius) sp. We found epidemiological and entomological evidence for local transmission of L. donovani in areas previously considered as non-endemic for VL. The national VL elimination program should revise the endemicity status of these districts and extend surveillance and control activities to curb further transmission of the disease.

We conducted a field evaluation using qualitative and quantitative methods to assess freeze prevention of vaccines transported and stored in a recently developed, World Health Organization-prequalified freeze-preventive cold box (FPCB) as compared to currently used standard cold boxes (SCBs). The study assessed the FPCB's practical use, health worker acceptance, health system fit (including cost considerations), and challenges faced by health workers in variable conditions and geographical settings. The evaluation took place in five health facilities across hilly and plains districts of Nepal in two phases: Phase 1 involved FPCBs in simulated use alongside SCBs. In Phase 2, actual vaccines were used in the FPCBs. The study gathered quantitative data from logbooks and electronic temperature monitors placed inside and outside the cold boxes. Qualitative data were collected from health workers, cold chain personnel, and immunization program managers involved in the vaccine cold chain at multiple levels. No damage, durability issues, or freezing incidents were observed when using FPCBs, but two incidents of freezing occurred when using SCBs. FPCBs also took longer to cool down than SCBs. Participants mostly found the FPCB to be safe and user friendly for vaccine transportation and short-term storage. Advantages of the FPCB as compared to the SCB include its ability to minimize vaccine wastage, to keep freeze-sensitive vaccines safe (the average value of freeze-sensitive vaccines transported per shipment was $1,704), and to ease preparation through elimination of the need to condition ice packs. Procurement price ranges for FPCBs overlap those for SCBs. Disadvantages of the FPCB include its greater size and weight, which require more personnel and vehicles during transportation. This suggests that lighter and smaller FPCBs would be more effective and acceptable for the Nepal immunization program and other, similar immunization programs conducted globally.
RESUMEN
In Nepal's constitution, safe abortion care is recognized as an essential component of a comprehensive approach to fulfill individuals' sexual and reproductive health and rights. In the current context of transition to a three-level governance (federal, provincial, and local), there are opportunities to accelerate decentralization and devolution of decision-making power, increase access to and coverage of safe abortion services, and improve health outcomes. This article documents the processes and results of the policy change undertaken by the Ministry of Health and Population in collaboration with development partners to decentralize the approval process of safe abortion sites and providers with the objective to increase access to and coverage of safe abortion services. With the decentralization of certification, the approval process for safe abortion service sites and providers has become simpler, less time consuming, and less expensive by reducing cost of traveling to Kathmandu or approaching authorities at the federal level. This has resulted in expanding safe abortion services across the country including remote areas with marginalized populations. Evidence-based advocacy enabled policy change for decentralization of the approval process. Collaboration among stakeholders has been vital for implementing the policy change, including issuing directives from the federal to provincial levels and capacity strengthening of provincial level officials in understanding the requirements for approval of sites and providers.

BACKGROUND: Although there has been a significant focus on improving maternal and newborn health and expanding services in Nepal, the expected positive impact on the health of mothers and newborns has not been achieved to the desired extent. Nepal not only needs to focus on improving access to and coverage of services but also the quality to achieve Sustainable Development Goals (SDG) by 2030. In this context, we aimed to analyze Basic Emergency Obstetric and Neonatal Care (BEmONC) service availability and readiness in Health Facilities (HFs) of Nepal. METHODS: We analyzed data from nationally representative Nepal Health Facility Survey (NHFS), 2021. BEmONC service availability and readiness in HFs was measured based on the "Service Availability and Readiness" manual of World Health Organization (WHO). We measured service availability by seven BEmONC signal functions. The readiness score was calculated for three domains- guidelines and staff training, essential equipment/supplies, and essential medicines on a scale of 100, and the average score for the three domains was the overall readiness score. We performed weighted descriptive and inferential analysis to account complex survey design of NHFS 2021. We summarized continuous variables with descriptive statistics like mean, standard deviation, median and interquartile range whereas categorical variables with percent and 95% confidence interval (CI). We applied simple, and multivariate linear regression to determine factors associated with the readiness of HFs for BEmONC services, and results were presented as beta (ß) coefficients and 95% CI. RESULTS: Of total 804 HFs offering normal vaginal delivery services, 3.1%, 89.2%, 7.7% were federal/provincial hospitals, local HFs, and private hospitals respectively. A total of 45.0% (95% CI: 34.9, 55.6) federal/provincial hospitals, 0.3% (95% CI: 0.2, 0.6), local HFs (district hospital, primary health care centers, health posts, urban health centers) and 10.5% (95% CI: 6.6, 16.4) private hospitals, had all seven BEmONC signal functions. The overall readiness of federal/provincial hospitals, local HFs, and private hospitals were 72.9±13.6, 54.2±12.8, 53.1±15.1 respectively. In multivariate linear regression, local HFs (ß = -12.64, 95% CI: -18.31, -6.96) and private hospitals had lower readiness score (ß = -18.08, 95% CI: -24.08, -12.08) compared to federal/provincial level hospitals. HFs in rural settings (ß = 2.60, 95% CI: 0.62, 4.58), mountain belts (ß = 4.18, 95% CI: 1.65, 6.71), and HFs with external supervision (ß = 2.99, 95% CI:1.08, 4.89), and quality assurance activities (ß = 3.59, 95% CI:1.64, 5.54) had better readiness scores. CONCLUSION: The availability of all seven BEmONC signal functions and readiness of HFs for BEmONC services are relatively low in local HFs and private hospitals. Accelerating capacity development through training centers at the federal/provincial level, onsite coaching, and mentoring, improving procurement and supply of medicines through federal/provincial logistic management centers, and regular supportive supervision could improve the BEmONC service availability and readiness in facilities across the country.

Evidence should be the foundation for a well-designed family planning (FP) program, but existing evidence is rarely aligned with and/or synthesized to speak directly to FP programmatic needs. Based on our experience cocreating FP research and learning agendas (FP RLAs) in Côte d'Ivoire, Malawi, Mozambique, Nepal, Niger, and Uganda, we argue that FP RLAs can drive the production of coordinated research that aligns with national priorities.To cocreate FP RLAs, stakeholders across 6 countries conducted desk reviews of 349 documents and 106 key informant interviews, organized consultation meetings in each country to prioritize evidence gaps and generate research and learning questions, and, ultimately, formed 6 FP RLAs comprising 190 unique questions. We outline the process for consensus-driven development of FP RLAs and communicate the results of an analysis of the questions in each FP RLA across 4 technical areas: self-care, equity, high impact practices, and youth. Each question was categorized as a learning versus research question, the former indicating an opportunity to synthesize existing evidence and the latter to conduct new research to answer the question. Themes emerging from the data shed light on shared evidence gaps across the 6 countries. We argue that similarities and differences in the questions in each FP RLA reflect the unique implementation experience and context, as well as each country's placement on the FP S-curve. Early uses of the FP RLAs include informing the development of FP costed implementation plans and FP2030 commitments. FP RLAs have also been discussed in multiple thematic working groups. For FP stakeholders, these FP RLAs represent a consensus-based agenda that can guide the generation and synthesis of evidence to answer each country's most pressing questions, ultimately driving progress toward increasingly evidence-based programming and policy.

Vaccine hesitancy during the COVID-19 pandemic continues to be an issue in terms of global efforts to decrease transmission rates. Despite high demand for the vaccines in Nepal, the country still contends with challenges related to vaccine accessibility, equitable vaccine distribution, and vaccine hesitancy. Study objectives were to identify: 1) up-take and intention for use of COVID-19 vaccines, 2) factors associated with vaccine up-take, and 3) trusted communication strategies about COVID-19 and the vaccines. A quantitative survey was implemented in August and September 2021 through an initiative at the Nepali Ministry of Health and Population Department of Health Services, Family Welfare Division. Data were collected from 865 respondents in three provinces (Bagmati, Lumbini, and Province 1). Ordinal multivariate logistic regression was utilized to determine relationships between vaccination status and associated factors. Overall, 62% (537) respondents were fully vaccinated and 18% (159) were partially vaccinated. Those respondents with higher education (p < .001) and higher household income (p < .001) were more likely vaccinated. There were also significant differences in vaccine up-take across the three provinces (p < .001). Respondents who were vaccinated were significantly more likely to perceive vaccines as efficacious in terms of preventing COVID-19 (p = .004) and preventing serious outcomes (p = .010). Among both vaccinated and unvaccinated individuals, there was a high level of trust in information about COVID-19 vaccines provided through local health-care workers [e.g. nurses and physicians]. These results are consistent with other findings within the South Asia region. Targeted advocacy and outreach efforts are needed to support ongoing COVID-19 vaccination campaigns throughout Nepal.

BACKGROUND: Scrub typhus is a largely ignored tropical disease and a leading cause of undifferentiated febrile illness in the areas of tsutsugamushi triangle caused by Orientia tsutsugamushi. It is frequently diagnosed in South Asian countries, although clear epidemiological information is not available from Nepal. After the 2015 earthquake in Nepal, a sudden upsurge in scrub typhus cases was reported. The objective of this study was to investigate epidemiology of scrub typhus and its causative agents in humans, animals, and chigger mites to understand the ongoing transmission ecology. METHODS: Scrub typhus cases with confirmed diagnosis throughout the country were included in the analysis. Studies were concentrated in the Chitwan district, the site of a major outbreak in 2016. Additional nation-wide data from 2015 to 2017 available from the government database included to analyse the disease distribution by geographical mapping. RESULTS: From 2015 to 2017, 1239 scrub typhus cases were confirmed with the largest outbreak occurring in 2016 with 831 (67.1%) cases. The case fatality rate was 5.7% in 2015 which declined to 1.1% in 2017. A nationwide outbreak of scrub typhus was declared as the cases were detected in 52 out of the 75 districts of Nepal. Seasonal trend was observed with a peak during August and September. In addition to the human cases, the presence of O. tsutsugamushi was also confirmed in animals (rodents) and chigger mites (Leptotrombidium imphalum) from the outbreak areas of southern Nepal. CONCLUSION: The detection of O. tsutsugamushi in humans, animals, and chigger mites from outbreak locations and wide-spread reports of scrub typhus throughout the country consecutively for 3 years confirms the ongoing transmission of O. tsutsugamushi with a firmly established ecology in Nepal. The country's health system needs to be strengthened for systematic surveillance, early outbreak detection, and immediate actions including treatment and preventive measures.

BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is currently a threat to malaria elimination due to risk of primaquine-induced haemolysis in G6PD deficient individuals. The World Health Organization (WHO) recommends G6PD screening before providing primaquine as a radical treatment against vivax malaria. However, evidence regarding the prevalence and causing mutations of G6PD deficiency in Nepal is scarce. METHODS: A cross-sectional, population-based, prevalence study was carried out from May to October 2016 in 12 malaria-endemic districts of Nepal. The screening survey included 4067 participants whose G6PD status was determined by G6PD Care Start™ rapid diagnostic test and genotyping. RESULTS: The prevalence of G6PD deficiency at the national level was 3.5% (4.1% among males and 2.1% among females). When analysed according to ethnic groups, G6PD deficiency was highest among the Janajati (6.2% overall, 17.6% in Mahatto, 7.7% in Chaudhary and 7.5% in Tharu) and low among Brahman and Chhetri (1.3%). District-wise, prevalence was highest in Banke (7.6%) and Chitwan (6.6%). Coimbra mutation (592 C>T) was found among 75.5% of the G6PD-deficient samples analysed and Mahidol (487 G>A) and Mediterranean (563 C>T) mutations were found in equal proportions in the remaining 24.5%. There was no specific geographic or ethnic distribution for the three mutations. CONCLUSIONS: This study has identified populations with moderate to high prevalence of G6PD deficiency which provides strong evidence supporting the WHO recommendations to screen G6PD deficiency at health facility level before the use of primaquine-based radical curative regimen for Plasmodium vivax.

BACKGROUND: Bangladesh, India, and Nepal aim for the elimination of Visceral Leishmaniasis (VL), a systemic parasitic infectious disease, as a public health problem by 2020. For decades, male patients have comprised the majority of reported VL cases in this region. By comparing this reported VL sex ratio to the one observed in population-based studies conducted in the Indian subcontinent, we tested the working hypothesis that mainly socio-cultural gender differences in healthcare-seeking behavior explain this gender imbalance. METHODOLOGY/PRINCIPAL FINDINGS: We compared the observed sex ratio of male versus female among all VL cases reported by the health system in Nepal and in the two most endemic states in India with that observed in population-based cohort studies in India and Nepal. Also, we assessed male sex as a potential risk factor for seroprevalence at baseline, seroconversion, and VL incidence in the same population-based data. The male/female ratio among VL cases reported by the health systems was 1.40 (95% CI 1.37-1.43). In the population cohort data, the age- and study site-adjusted male to female risk ratio was 1.27 (95% CI 1.08-1.51). Also, males had a 19% higher chance of being seropositive at baseline in the population surveys (RR 1.19; 95% CI 1.11-1.27), while we observed no significant difference in seroconversion rate between both sexes at the DAT cut-off titer defined as the primary endpoint. CONCLUSIONS/SIGNIFICANCE: Our population-based data show that male sex is a risk factor for VL, and not only as a socio-cultural determinant. Biological sex-related differences likely play an important role in the pathogenesis of this disease.

BACKGROUND: As malaria cases have declined throughout Nepal, imported cases comprise an increasing share of the remaining malaria caseload, yet how to effectively target mobile and migrant populations (MMPs) at greatest risk is not well understood. This formative research aimed to confirm the link between imported and indigenous cases, characterize high-risk MMPs, and identify opportunities to adapt surveillance and intervention strategies to them. METHODS: The study used a mixed-methods approach in three districts in far and mid-western Nepal, including (i) a retrospective analysis of passive surveillance data, (ii) a quantitative health facility-based survey of imported cases and their MMP social contacts recruited by peer-referral, and (iii) focus group (FG) discussions and key informant interviews (KIIs) with a subset of survey participants. Retrospective case data were summarised and the association between monthly indigenous case counts and importation rates in the previous month was investigated using Bayesian spatio-temporal regression models. Quantitative data from structured interviews were summarised to develop profiles of imported cases and MMP contacts, including travel characteristics and malaria knowledge, attitudes and practice. Descriptive statistics of the size of cases' MMP social networks are presented as a measure of potential programme reach. To explore opportunities and barriers for targeted malaria surveillance, data from FGs and KIIs were formally analysed using a thematic content analysis approach. RESULTS: More than half (54.1%) of malaria cases between 2013 and 2016 were classified as imported and there was a positive association between monthly indigenous cases (incidence rate ratio (IRR) 1.02 95% CI 1.01-1.03) and the previous month's case importation rate. High-risk MMPs were identified as predominantly adult male labourers, who travel to malaria endemic areas of India, often lack a basic understanding of malaria transmission and prevention, rarely use ITNs while travelling and tend not to seek treatment when ill or prefer informal private providers. Important obstacles were identified to accessing Nepali MMPs at border crossings and at workplaces within India. However, strong social connectivity during travel and while in India, as well as return to Nepal for large seasonal festivals, provide opportunities for peer-referral-based and venue-based surveillance and intervention approaches, respectively. CONCLUSIONS: Population mobility and imported malaria cases from India may help to drive local transmission in border areas of far and mid-western Nepal. Enhanced surveillance targeting high-risk MMP subgroups would improve early malaria diagnosis and treatment, as well as provide a platform for education and intervention campaigns. A combination of community-based approaches is likely necessary to achieve malaria elimination in Nepal.

BACKGROUND: A significant reduction in malaria cases over the recent years in Nepal has encouraged the government to adopt a goal of "malaria-free nation by 2025." Nevertheless, to achieve this goal, it is critical to identify the epidemiological burden of malaria by specific regions and areas for an effective targeted intervention. The main objective of this study was to estimate the risk of malaria at Village Development Committee (VDC) level in Nepal based on disease, vector, parasite, and geography. METHODS: In 2012, the micro-stratification of malaria risk was carried out in 75 districts of Nepal. Instruments such as a questionnaire, case record forms, and guidelines for malaria micro-stratification were developed and pre-tested for necessary adaptations. Village Development Committee (VDC)-wise malaria data were analyzed using exploratory statistics and were stratified by geographical variables that contributed to the risk of malaria. To understand the transmission risk at VDC level, overlay analysis was done using ArcGIS 10. To ensure transparent, reproducible, and comprehensible risk assessment, standard scoring method was selected and utilized for data from 2009 to 2011. Thus identified, three major variables (key determinants) were given weights (wt.) accordingly to stratification of the malaria risk (disease burden, "0.3" wt.; ecology/vector transmission, "0.5" wt.; and vulnerability-population movement, "0.2" wt.). Malaria risk in a VDC was determined based on the overall scores and classified into four categories: no risk, low risk, moderate risk, and high risk. RESULTS: Analyzing the overall risk based on scoring of the total VDCs (n = 3976), 54 (1.36%), 201 (5.06%), 999 (25.13%), and 2718 (68.36%) were identified as high-, moderate-, low-, and no-risk categories for malaria, respectively. Based on the population statistics, 3.62%, 9.79%, 34.52%, and 52.05% of the country's total population live in high-risk, moderate-risk, low-risk, and no-risk VDCs for malaria, respectively. Our micro-stratification study estimates are 100,000 population at high risk. Regional distribution showed that the majority of the high-risk VDCs were identified in the Far- and Mid-western regions (19 and 18 VDCs) followed by Central and Western regions (10 and 7 VDCs) with no high-risk VDCs in the Eastern region. Similarly, 77, 59, 27, 24, and 14 VDCs of the Central, Mid-western, Western, Eastern, and Far-western regions, respectively, were found under moderate malaria risk. Of the low-risk VDCs, 353, 215, 191, 148, and 92 were respectively from the Central, Eastern, Western, Far-western, and Mid-western regions. CONCLUSIONS: The current micro-stratification study provides insights on malaria risk up to the VDC level. This will help the malaria elimination program to target interventions at the local level thereby ensuring the best utilization of available resources to substantially narrowed-down target areas. With further updates and refinement, the micro-stratification approach can be employed to identify the risk areas up to smaller units within the VDCs (ward and villages).
RESUMEN
Malaria is endemic in the southern plain of Nepal which shares a porous border with India. More than 80% cases of malaria in Nepal are caused by Plasmodium vivax. The main objective of this study was to review the epidemiology of P. vivax malaria infections as recorded by the national malaria control program of Nepal between 1963 and 2016. National malaria data were retrieved from the National Malaria program in the Ministry of Health, Government of Nepal. The epidemiological trends and malariometric indicators were analyzed. Vivax malaria has predominated over falciparum malaria in the past 53 years, with P. vivax malaria comprising 70-95% of the annual malaria infections. In 1985, a malaria epidemic occurred with 42,321 cases (82% P. vivax and 17% Plasmodium falciparum). Nepal had experienced further outbreaks of malaria in 1991 and 2002. Plasmodium falciparum cases increased from 2005 to 2010 but since then declined. Analyzing the overall trend between 2002 (12,786 cases) until 2016 (1,009 cases) shows a case reduction by 92%. The proportion of imported malaria cases has increased from 18% of cases in 2001 to 50% in 2016. The current trends of malariometric indices indicate that Nepal is making a significant progress toward achieving the goal of malaria elimination by 2025. Most of the cases are caused by P. vivax with imported malaria comprising an increasing proportion of cases. The malaria control program in Nepal needs to counter importation of malaria at high risk areas with collaborative cross border malaria control activities.

BACKGROUND: Nepal has made significant progress against the Millennium Development Goals for maternal and child health over the past two decades. However, disparities in use of maternal health services persist along geographic, economic, and sociocultural lines. METHODS: Trends and inequalities in the use of maternal health services in Nepal between 1994 and 2011 were examined using four Nepal Demographic and Health Surveys (NDHS), nationally representative cross-sectional surveys conducted by interviewing women who gave birth 3-5 years prior to the survey. Sociodemographic disparities in maternal health service utilization were measured. Rate difference, rate ratios, and concentration index were calculated to measure income inequalities. FINDINGS: The percentage of mothers that received four antenatal care (ANC) consultations increased from 9% to 54%, the institutional delivery rate increased from 6% to 47%, and the cesarean section (C-section) rate increased from 1% in 1994 to 6% in 2011. The ratio of the richest and the poorest quintile mothers for use of four ANC, institutional delivery, and C-section delivery were 5.08 (95% CI: 3.82-6.76), 9.00 (95% CI: 6.55-12.37), and 9.37 (95% CI: 4.22-20.83), respectively. However, inequality is reducing over time; for the use of four ANC services, the concentration index fell from 0.60 (95% CI: 0.56-0.64) in 1994-1996 to 0.31 (95% CI: 0.29-0.33) in 2009-2011. For institutional delivery, the concentration index fell from 0.65 (95% CI: 0.62-0.70) to 0.40 (95% CI: 0.38-0.40) between 1994-1996 and 2009-2011. For C-section deliveries, an increase in concentration index was observed, 0.64 (95% CI: 0.51-0.77); 0.76 (95% CI: 0.64-0.88); 0.77 (95% CI: 0.71-0.84); and 0.66 (95% CI: 0.60-0.72) in the periods 1994-1996, 1999-2001, 2004-2006, and 2009-2011, respectively. All sociodemographic variables were significant predictors of use of maternal health services, out of which maternal education was the most powerful. CONCLUSION: To increase equitable use of maternal health services in Nepal there is a need to strengthen the health system to increase access to and utilization of services among poorer women, those with less education, and those living in remote areas. Beyond the health sector stronger efforts are needed to tackle the root causes of health inequality, reduce poverty, increase female education, eradicate caste/ethnicity based social discrimination, and invest in the development of remote areas.
