RESUMO

OBJECTIVE: To present evaluation of a quality improvement program for Accredited Social Health Activists (ASHAs). METHODS: This community intervention trial was conducted in Ballabgarh, India during 2012-2014 with two Primary Health Center (PHC) areas being the intervention areas and two PHC areas being non-intervention areas receiving standard care. Interventions included two-day training in technical and communication skills of ASHAs followed by supportive supervision in the field. Intervention was evaluated by comparing pre and post training scores, feedback from postnatal mothers and a difference-in-difference (DID) analysis on baseline and endline knowledge-practice survey of recently delivered mothers with 95% confidence intervals. RESULTS: Only 11.1% ASHAs addressed specific barriers for adopting healthy behaviors. Sixty eight (91.8%) ASHAs attended the training after which knowledge improved by 33.3% (p < 0.001). ASHAs in intervention areas were rated by mothers (n = 69) to have better communication skills (81.2% vs. 59.7%, p = 0.005), make more postnatal visits (52.2% vs. 22.2%; p < 0.001), give advice on newborn care (64% vs. 50.5%; p < 0.001) as compared to standard care area ASHAs. Endline survey (n = 1360) showed a significant improvement in frequency of antenatal visits (0.26;0.19-0.33), knowledge about free transport (0.12;0.05-0.18), better cord-care practices (0.15;0.07-0.22), kangaroo mother care (0.19;0.13-0.25), delayed first bath (0.13;0.06-0.20), restrictive handling (0.11;0.06-0.15) and hand-washing (0.19;0.13-0.25). CONCLUSIONS: Quality improvement program can help improve ASHA's performance which in turn can address higher neonatal mortality in India.

RESUMO

Interferon-τ (IFNT) is a major cytokine produced by the ruminant trophoectoderm during the peri-implantation period exerting immunomodulatory actions on various cells including neutrophils. The current in vitro study was undertaken to analyze the concentration-dependent effects of IFNT on neutrophil gene dynamics to understand its possible role in implantation process. The neutrophils were isolated from the blood of heifers and were cultured subjecting them to different IFNT concentrations (1, 5, or 10 ng/mL). The gene-expression patterns of different interferon-stimulated genes, l-selectin, CD31, CD11b, and progesterone-induced blocking factor (PIBF) were analyzed by quantitative real-time PCR. It was observed that at lower concentrations of IFNT, the IFI16, l-selectin, ISG15, and PIBF were upregulated, whereas at higher concentrations the same were down regulated. At all the experimental concentrations, IFI44, OAS1, MX genes were significantly upregulated and CD31, CD11b were significantly downregulated. At lower concentrations of IFNT, the neutrophil activity with respect to chemoattraction is stimulated, whereas at higher concentrations the same is reduced. Hence, it can be concluded that IFNT exerts concentration-dependent actions on neutrophil gene-expression dynamics indicating a fine modulation of its activity depending upon the temporal variation in its destined functions ultimately leading to successful implantation.

RESUMO

Evidence on influenza vaccine effectiveness from low and middle countries (LMICs) is limited due to limited institutional capacities; lack of adequate resources; and lack of interest by ministries of health for influenza vaccine introduction. There are concerns that the highest ethical standards will be compromised during trials in LMICs leading to mistrust of clinical trials. These factors pose regulatory and operational challenges to researchers in these countries. We conducted a community-based vaccine trial to assess the efficacy of live attenuated influenza vaccine and inactivated influenza vaccine in rural north India. Key regulatory challenges included obtaining regulatory approvals, reporting of adverse events, and compensating subjects for trial-related injuries; all of which were required to be completed in a timely fashion. Key operational challenges included obtaining audio-visual consent; maintaining a low attrition rate; and administering vaccines during a narrow time period before the influenza season, and under extreme heat. We overcame these challenges through advanced planning, and sustaining community engagement. We adapted the trial procedures to cope with field conditions by conducting mock vaccine camps; and planned for early morning vaccination to mitigate threats to the cold chain. These lessons may help investigators to confront similar challenges in other LMICs.

RESUMO

Background: Planning a comprehensive program addressing neonatal mortality will require a detailed situational analysis of available neonatal-specific health infrastructure. Methods: We identified facilities providing essential and sick neonatal care (ENC, SNC) by a snowballing technique in Ballabgarh Block. These were assessed for infrastructure, human resource and equipment along with self-rated competency of the staff and compared with facility-based or population-based norms. Results: A total of 35 facilities providing ENC and 10 facilities for SNC were identified. ENC services were largely in the public-sector domain (68.5% of births) and were well distributed in the block. SNC burden was largely being borne by the private sector (66% of admissions), which was urban-based. The private sector and nurses reported lower competency especially for SNC. Only 53.9% of government facilities and 17.5% of private facilities had a fully equipped newborn care corner. Conclusions: Serious efforts to reduce neonatal mortality would require major capacity strengthening of the health system, including that of the private sector.

RESUMO

BACKGROUND: Despite acute respiratory infections being a major cause of death among children in developing countries including India, there is a lack of community-based studies that document its burden and aetiology. METHODS: A dynamic cohort of children aged 0-10 years was established in four villages in a north Indian state of Haryana from August 2012 onwards. Trained health workers conducted weekly home visits to screen children for acute respiratory infection (ARI) defined as one of the following: cough, sore throat, nasal congestion, earache/discharge, or breathing difficulty. Nurses clinically assessed these children to grade disease severity based on standard age-specific guidelines into acute upper or lower respiratory infection (AURI or ALRI) and collected nasal/throat swabs for pathogen testing. RESULTS: Our first year results show that ARI incidence in 0-10 years of age was 5.9 (5.8-6.0) per child-year with minimal gender difference, the ALRI incidence in the under-five age group was higher among boys (0.43; 0.39-0.49) as compared to girls (0.31; 0.26-0.35) per child year. Boys had 2.4 times higher ARI-related hospitalization rate as compared to girls. CONCLUSION: ARI impose a significant burden on the children of this cohort. This study platform aims to provide better evidence for prevention and control of pneumonia in developing countries.

RESUMO

BACKGROUND: India is a high tuberculosis burden and large population setting country. Multidrug-resistant tuberculosis patient has to undergo 24-27 months treatment and is expected to adhere to it. There is a need to increase compliance of MDR Regimen in MDR-TB cases, to prevent its further spread. The present study focuses on describing the role of home care support with counseling in the outcome of MDR-TB patients, in Delhi, India. MATERIAL AND METHODS: This is a prospective study carried out at a Community Health Centre, Delhi, involving 113 MDR-TB patients as and when they got registered with DOTS Plus centres, in two government hospitals of Delhi between August 2009 and March 2010. The study period was August 2009 to October 2012. These patients received daily MDR Regimen from their respective DOTS Providers. The patients' names and addresses were taken from the lists supplied by these hospitals. Final analysis was carried out for 101 MDR-TB cases. RESULTS: Out of 101 patients treatment outcomes were: 69.3% cured and 2.0% treatment completed (treatment success rate 71.3%). A low default rate of 6.9% was seen which is assumed to be due to the home based care. CONCLUSION: These results indicate that Home based care with counseling support is an important intervention in management of MDR-TB patients and it needs to be substantiated by further research.

RESUMO

OBJECTIVE: To assess the effectiveness of a multi-component school based intervention in improving knowledge and behavioral practices regarding diet, physical activity and tobacco use in middle schoolchildren of rural-Ballabgarh, North-India. METHODS: A total of 40 middle schools were grouped into two, based on geographic proximity and randomly assigned to the intervention or control group in a cluster randomized controlled trial. The target population consisted of 2,348 children studying in 6th and 7th grades in these schools. The intervention consisted of a school component (policies), a classroom component (activities) and a family component [Information Education & Communication (IEC) material]. The main outcome measures were knowledge and behavioral changes in physical activity, diet and tobacco which were self- reported. RESULTS: Post-intervention, a significant number of intervention schools adopted the tobacco policy (16/19), physical activity policy (6/19) and healthy food policy (14/19) as compared to the control schools (n = 21). Knowledge about physical activity, diet and tobacco improved significantly in the intervention group as compared to the control group. Proportion of students attending Physical Training (PT) classes for five or more days in a week in the intervention group compared to the control group increased significantly (17.8%; p < 0.01). Proportion of students consuming fruits increased in the intervention group compared to the control group (10%; p < 0.01). Pre-post decrease in the prevalence of current smoking was significantly more in the intervention group as compared to the control group (7.7%; p < 0.01). CONCLUSIONS: Healthy settings approach for schools is feasible and effective in improving knowledge and behavioral practices of non-communicable diseases (NCD) risk factors in adolescents in rural India.

RESUMO

INTRODUCTION: Physical activity (PA) is protective against non-communicable diseases and it can reduce premature mortality. However, it is difficult to assess the frequency, duration, type and intensity of PA. The global physical activity questionnaire (GPAQ) has been developed by World Health Organization with the aim of having valid and reliable estimates of PA. The primary aim of this study is to assess the repeatability of the GPAQ instrument and the secondary aim is to validate it against International Physical Activity Questionnaire (IPAQ) and against an objective measure of PA (i.e., using pedometers) in both rural and peri-urban areas of North India. METHODS: A total of 262 subjects were recruited by random selection from Ballabgarh Block of Haryana State in India. For test retest repeatability of GPAQ and IPAQ, the instruments were administered on two occasions separated by at least 3 days. For concurrent validity, both questionnaires were administered in random order and for criterion validity step counters were used. Spearman's correlation coefficient, intra-class correlation (ICC) and Cohen's kappa was used in the analysis. RESULTS: For GPAQ validity, the spearman's Rho ranged from 0.40 to 0.59 and ICC ranged from 0.43 to 0.81 while for IPAQ validity, spearman correlation coefficient ranged from 0.42 to 0.43 and ICC ranged from 0.56 to 0.68. The observed concurrent validity coefficients suggested that both the questionnaires had reasonable agreement (Spearman Rho of >0.90; P < 0.0001; ICC: 0.76-0.91, P < 0.05). CONCLUSIONS: GPAQ is similar to IPAQ in measuring PA and can be used for measurement of PA in community settings.

RESUMO

OBJECTIVE: To assess sex-specific differentials in child survival from 1992-2011. METHODS: We analyzed data from the electronic database of Health and Demographic Surveillance System (HDSS) site in Ballabgarh in North India. RESULTS: Sex ratio at birth was adverse for girls throughout the study period (821 to 866 girls per 1,000 boys) and was lowest in the period 2004-2006 at 821 girls per 1,000 boys. Overall, under-five mortality rates during the period 1992-2011 remained stagnant due to increasing neonatal mortality rate (9.2 to 27.7 P< 0.001). Mortality rates among girls were consistently and significantly higher than boys during the post-neonatal period (160% to 200% higher) as well as in childhood(160% to 230% higher). CONCLUSIONS: Strategies to address the neonatal mortality and gender differences are required for further reductions in child mortality in India.

RESUMO

BACKGROUND: Relating Information on causes of deaths to implementation of health interventions provides vital information for program planning and evaluation. This paper from Ballabgarh Health and Demographic Surveillance System (HDSS) site in north India looks at temporal trends and gender differentials in the causes of death among under-five children. METHODS: Data on causes of death for 1972-74, 1982-84, 1992-94, 2002-04 were taken from existing HDSS publications and database. Physicians' assigned causes of death were based on narratives by lay health worker till 1994 and later by verbal autopsy. Cause Specific Mortality Fractions (CSMF) and Cause Specific Mortality Rates (CSMR) per 1000 live births were calculated for neonatal (<1 month) and childhood (1-59 months) period. Gender difference was estimated by calculating ratio of CSMR between girls and boys. Available information on coverage of childhood interventions in the HDSS was retrieved and compiled. RESULTS: The CSMF of prematurity and sepsis was 32% and 17.6% during neonatal period in 2002-04. The share of infections in all childhood deaths decreased from 55.2% in 1972-74 to 43.6% in 2002-04. All major causes of mortality (malnutrition, diarrhea and acute lower respiratory infection) except injuries showed a steep decline among children and seem to have plateued in last decade. Most of disease specific public health interventions were launched in mid eighties. . Girls reported significantly higher mortality rates for prematurity (RR 1.52; 95% CI 1.01-2.29); diarrhea (2.29; 1.59 - 3.29), and malnutrition (3.37; 2.05 - 5.53). CONCLUSIONS: The findings of the study point out to the need to move away from disease-specific to a comprehensive approach and to address gender inequity in child survival through socio-behavioural approaches.

RESUMO

Noncommunicable diseases (NCDs) are emerging as an important public health problem in developing countries. The risk factors for NCDs are initiated during childhood and adolescence. The aim of this review was to assess the effectiveness of school-based interventions for prevention of NCD risk factors (physical inactivity, diet, and tobacco consumption), and identify processes that affect the main outcome. The retrieved studies from 2001 to 2010 were analyzed for their methodological quality (using standard guidelines), settings, intervention components, and main outcomes. The literature search identified 37 studies. The proportion of studies showing a positive result was 83% (10/12) among those that involved family, 87%(7/8) that involved both community and family, and 76% (13/17) that involved school only. Overall, 80% of the studies reported at least some evidence of a positive intervention effect. The current literature search supports the effectiveness of school-based interventions for prevention of risk factors associated with NCDs.

RESUMO

BACKGROUND: Most of the standard verbal autopsy tools are long and are used in a research setting. This study aims to compare a short verbal autopsy (VA) tool developed at Ballabgarh, India to be used by health workers for routine mortality surveillance with a standard tool. METHODS: A short VA tool was developed which was used by health workers during their routine house visits while a standard International Network of Field Sites with continuous Demographic Evaluation (INDEPTH) VA tool was filled by trained research workers for all adult deaths that occurred in 2008. The cause-specific mortality fraction using two tools, validity of the Comprehensive Rural Health Services Project (CRHSP) VA tool with INDEPTH VA tool as reference and agreement between the two tools, was compared. RESULTS: The cause-specific mortality fraction was 11.6% and 12% for ischaemic heart disease (IHD), 10.6% and 11.8% for chronic pulmonary obstructive disease (COPD), and 9.4% and 7.3% for tuberculosis, using the INDEPTH and CRHSP VA tool, respectively. 16% and 21% of the deaths could not be classified using the INDEPTH and CRHSP VA tool respectively. The sensitivity of the CRHSP VA tool was 78.5% for IHD, 80% for COPD, 58.3% for tuberculosis, 92.8% for malignant neoplasm and 97.2% for intentional self harm. The kappa between two tools for IHD, COPD, tuberculosis, malignant neoplasm and intentional self harm was 0.754, 0.711, 0.628, 0.876 and 0.892 respectively. CONCLUSION: The short VA tool had a good sensitivity and fair to excellent agreement with the standard tool in different age groups across the major causes of death. It can be used within the routine healthcare delivery framework and can fill the gap in mortality surveillance.

RESUMO

BACKGROUND: The routine use of verbal autopsy in health-care delivery settings has been limited. Hence, the performance of neonatal and postneonatal verbal autopsy (VA) tools developed at the Comprehensive Rural Health Services Project (CRHSP), Ballabgarh (India), were assessed. METHODS: Short VA tools developed by CRHSP were filled by health workers during their routine house visits while standard VA tools of the International Network of Field Sites with continuous Demographic Evaluation (INDEPTH) were filled by trained research workers for all 143 under-five-children deaths that occurred in 2008. The level of agreement in the cause of death assigned by the two VA tools was assessed by kappa and by comparison of the cause-specific mortality fractions. RESULTS: Among 65 neonatal deaths, the cause specific mortality fraction (CSMF) was 43.1% and 40% for low birthweight, 15.4% and 26.2% for birth asphyxia, and 7.7% and 10.8% for pneumonia by INDEPTH and CRHSP VA tools respectively. In 78 deaths among 29-days to <5-year olds, the CSMF was 29.4% and 26.9% for diarrhoea, and 16.6% each for pneumonia using the INDEPTH and CRHSP VA tools respectively. Kappa for most causes of death was more than 0.8, except for birth asphyxia, which had a kappa of 0.678. CONCLUSIONS: Short VA tools have a satisfactory performance in field settings, which can be used routinely by health workers for filling the gaps in the cause-of-death information in places where medical certification of cause of death is deficient.

RESUMO

BACKGROUND: The International Network of field sites with continuous Demographic Evaluation of Populations and Their Health (INDEPTH) has 34 Health and Demographic Surveillance System (HDSS) in 17 different low and middle-income countries. Of these, 23 sites are in Africa, 10 sites are in Asia, and one in Oceania. The INDEPTH HDSS sites in Asia identified chronic non-communicable diseases (NCDs) as a neglected area of attention. As a first step, they conducted NCD risk factor surveys within nine sites in five countries. These sites are now looking to broaden the agenda of research on NCDs using the baseline data to inform policy and practice. METHODS: A conceptual framework for translating research into action for NCDs at INDEPTH sites was developed. This had five steps - assess the problem, understand the nature of the problem, evaluate different interventions in research mode, implement evidence-based interventions in programme mode, and finally, share knowledge and provide leadership to communities and countries. Ballabgarh HDSS site in India has successfully adopted these steps and is used as a case study to demonstrate how this progress was achieved and what factors were responsible for a successful outcome. RESULTS: Most of the HDSS sites are in the second step of the process of translating research to action (understand the problem). The conduct of NCD risk factor surveys has enabled an assessment of the burden of NCD risk together with determinants in order to understand the burden at the population level. The experience from Ballabgarh HDSS exemplifies that the following steps - pilot testing the interventions, implementing activities in programme mode, and finally, share knowledge and provide leadership - are also possible in rural settings in low-income countries. The critical success factors identified were involvement of a premier medical institution, pre-existing links to policy makers and programme managers, strong commitment of the HDSS team and adequate human resource capacity. CONCLUSION: All INDEPTH HDSS sites now need to strengthen their links to health systems at different levels and enhance their capacity to engage different stakeholders in their respective country settings so as to translate the current knowledge into actions that can benefit the health of the population they serve and beyond.

RESUMO

BACKGROUND: Acute respiratory infection (ARI) is a major killer of children in developing countries. Although the frequency of ARI is similar in both developed and developing countries, mortality due to ARI is 10-50 times higher in developing countries. Viruses are common causes of ARI among such children, yet the disease burden of these infections in rural communities is unknown. METHODOLOGY/PRINCIPAL FINDINGS: A prospective longitudinal study was carried out in children enrolled from two rural Indian villages at birth and followed weekly for the development of ARI, classified as upper respiratory infection, acute lower respiratory infection (ALRI), or severe ALRI. Respiratory syncytial virus (RSV), influenza, parainfluenza viruses and adenoviruses in nasopharyngeal aspirates were detected by direct fluorescent antibody testing (DFA) and, in addition, centrifugation enhanced culture for RSV was done. 281 infants enrolled in 39 months and followed until 42 months. During 440 child years of follow-up there were 1307 ARIs, including 236 ALRIs and 19 severe ALRIs. Virus specific incidence rates per 1000 child years for RSV were total ARI 234, ALRI 39, and severe ALRI 9; for influenza A total ARI 141, ALRI 39; for INF B total ARI 37; for PIV1 total ARI 23, for PIV2 total ARI 28, ALRI 5; for parainfluenza virus 3 total ARI 229, ALRI 48, and severe ALRI 5 and for adenovirus total ARI 18, ALRI 5. Repeat infections with RSV were seen in 18 children. CONCLUSIONS/SIGNIFICANCE: RSV, influenza A and parainfluenza virus 3 were important causes of ARI among children in rural communities in India. These data will be useful for vaccine design, development and implementation purposes.

RESUMO

Respiratory syncytial virus (RSV) is the most commonly identified viral agent of acute respiratory tract infection (ARI) of young children and causes repeat infections throughout life. Limited data are available on the molecular epidemiology of RSV from developing countries, including India. This study reports on the genetic variability in the glycoprotein G gene among RSV isolates from India. Reverse transcription-PCR for a region of the RSV G protein gene was done with nasopharyngeal aspirates (NPAs) collected in a prospective longitudinal study in two rural villages near Delhi and from children with ARI seen in an urban hospital. Nucleotide sequence comparisons among 48 samples demonstrated a higher prevalence of group A (77%) than group B (23%) RSV isolates. The level of genetic variability was higher among the group A viruses (up to 14%) than among the group B viruses (up to 2%). Phylogenetic analysis revealed that both the GA2 and GA5 group A RSV genotypes were prevalent during the 2002-2003 season and that genotype GA5 was predominant in the 2003-2004 season, whereas during the 2004-2005 season both genotype GA5 and genotype BA, a newly identified group B genotype, cocirculated in almost equal proportions. Comparison of the nonsynonymous mutation-to-synonymous mutation ratios (dN/dS) revealed greater evidence for selective pressure between the GA2 and GA5 genotypes (dN/dS, 1.78) than within the genotypes (dN/dS, 0.69). These are among the first molecular analyses of RSV strains from the second most populous country in the world and will be useful for comparisons to candidate vaccine strains.

RESUMO

Respiratory syncytial virus (RSV) causes repeat infections throughout life. Antigenic variability in the RSV G protein may play a significant role in reinfections. A variable region of the RSV G gene was analyzed for 14 viruses from seven children who experienced initial and repeat infections. Eleven group A strains were in clades GA2 and GA5 and the three group B viruses were in the newly identified BA clade. In five children reinfections were caused by a heterologous group or genotype of RSV. Two children experienced infection and reinfection by viruses of the same clade, these virus pairs differed by only two to three amino acids in the region compared. This is the first report of RSV nucleotide sequence analysis from India and one of the few molecular characterizations of paired RSV from reinfections. Determining the molecular basis of reinfections may have important implications for RSV vaccine development.

RESUMO

OBJECTIVE: To estimate the cost of ambulatory (out-patient) and in-patient pediatric health services for the year 1999 provided by All India Institute of Medical Sciences (AIIMS) at all the three levels-primary, secondary and tertiary level. METHODS: The costing module developed by Children's Vaccines Initiative (CVI) was used. This rapid assessment tool focuses on collection of data at macro level by using key informants like doctors, nursing staff, accountant, store keeper, engineer etc. Cost per beneficiary was estimated separately for in-patients and out-patients and was calculated by dividing the total cost of the services by the number of beneficiaries for the year 1999. For the out-patient, the beneficiaries were the total out-patient attendees and for the in-patient, it was the total pediatric admissions multiplied by mean duration of stay in days. RESULTS: The cost per out-patient visit was INR.20.2 (US0.44 dollars@1US dollars=INR.46) at primary level, higher than INR14.5 (US0.31 dollars) at the secondary level, while at tertiary level it was INR 33.8 (US 0.73 dollars). At the primary and secondary level, non-physician cost was more than the physician cost, and for tertiary level, physician cost was much higher than the other costs. There were no in-patient services at primary level. The cost of in-patient services at secondary level was estimated as INR 419.30 (US 9.1 dollars) per patient per day with a bed occupancy rate of 60%. Two-fifths of the cost was due to nursing and other supportive staff and one fifth due to the doctor costs and overhead costs. The unit cost of INR 928 (US 20.2 dollars) per patient per day incurred at AIIMS with a bed occupancy rate of 100% was almost twice that of secondary level. In contrast to the secondary level, almost half the total costs at tertiary level was due to the doctors costs. CONCLUSIONS: Effective use of resources at lower level of care especially ambulatory care at primary level and inpatient care at secondary level can result in much higher savings for the system and also, the society. These would need to be appropriately strengthened.

RESUMO

The aim of the study was to evaluate the knowledge of mothers and grandmothers regarding breastfeeding and health-seeking behavior for neonatal sickness in a rural community. A cross-sectional survey, using a triangulation of qualitative (focus group discussion) and quantitative (structured questionnaire) methods was carried out. Although most of the grandmothers and mothers believed in early feeding within 2 h of delivery, they often administered prelacteal feeds such as ghutti and honey. Colostrum was considered beneficial. Most respondents believed that ghutti, water, or both should be given along with breastmilk. Diluted buffalo milk was the preferred choice if supplementation was required. It was thought that weaning should be introduced after 6 months of life. Mothers preferred to give dalia and khichri as the initial weaning food compared to roti and dal water by grandmothers. Both grandmothers and mothers felt that a baby who was playful and not crying excessively was usually healthy. Most of the respondents described the normal pattern of breathing, feeding, urination, and defecation adequately. Most of the grandmothers and mother's felt that by touching forehead and limbs of baby could reliably assess temperature. Refusal to feed was considered as a marker of a sickness by most grandmothers and mothers. However, they also believed that health-seeking for poor feeding could be delayed for 1 day. Respiratory distress was described by the presence of fast respiration, chest retractions, or noisy breathing. Most respondents did not know how to assess cyanosis or seizures. Jaundice was descried as yellowish discoloration of skin, eyes, and urine. Failure to pass urine for 4-6 h bothered most of the respondents. The first response to illness was home remedies. The choice of healthcare was unqualified village practitioners followed by government hospital. Knowledge regarding desirable breastfeeding practices was inadequate and quite a few inappropriate beliefs were widely prevalent. Although knowledge regarding sickness was present, health-seeking from qualified providers was considerably delayed with most respondents preferring village practitioners to government hospitals.
