Entomological indicators of Plasmodium species transmission in Goma Tsé-Tsé and Madibou districts, in the Republic of Congo.

BACKGROUND: Malaria remains a major public health problem in the Republic of Congo, with Plasmodium falciparum being the deadliest species of Plasmodium in humans. Vector transmission of malaria is poorly studied in the country and no previous report compared rural and urban data. This study aimed to determine the Anopheles fauna and the entomological indices of malaria transmission in the rural and urban areas in the south of Brazzaville, and beyond. METHODS: Indoor household mosquitoes capture using electric aspirator was performed in rural and urban areas during raining and dry seasons in 2021. The identification of Anopheles species was done using binocular magnifier and nested-PCR. TaqMan and nested-PCR were used to detect the Plasmodium species in the head/thorax and abdomens of Anopheles. Some entomological indices including the sporozoite infection rate, the entomological inoculation rate and the man biting rate were estimated. RESULTS: A total of 699 Anopheles mosquitoes were collected: Anopheles gambiae sensu lato (s.l.) (90.7%), Anopheles funestus s.l. (6.9%), and Anopheles moucheti (2.4%). Three species of An. gambiae s.l. were identified including Anopheles gambiae sensu stricto (78.9%), Anopheles coluzzii (15.4%) and Anopheles arabiensis (5.7%). The overall sporozoite infection rate was 22.3% with a predominance of Plasmodium falciparum, followed by Plasmodium malariae and Plasmodium ovale. Anopheles aggressiveness rate was higher in households from rural area (1.1 bites/night) compared to that from urban area (0.8 ib/p/n). The overall entomological inoculation rate was 0.13 ib/p/n. This index was 0.17 ib/p/n and 0.092 ib/p/n in rural and in urban area, respectively, and was similar during the dry (0.18 ib/p/n) and rainy (0.14 ib/p/n) seasons. CONCLUSION: These findings highlight that malaria transmission remains high in rural and urban area in the south of Republic of Congo despite the ongoing control efforts, thereby indicating the need for more robust interventions.

Plasmodium falciparum msp-1 and msp-2 genetic diversity and multiplicity of infection in isolates from Congolese patients in the Republic of Congo.

With limited up to date data from the Republic of Congo, the aim of this study was to investigate allelic polymorphism of merozoite surface protein-1 (msp-1) and merozoite surface protein-2 (msp-2). This will help assess the genetic diversity and multiplicity of Plasmodium falciparum infection (MOI), from uncomplicated malaria individuals living in Brazzaville. Between March and October 2021, a cross-sectional study was carried out at a health center in Madibou District located in the south of Brazzaville. Plasmodium infection was diagnosed in human blood by microscopy and the block 2 of P. falciparum msp-1 and block 3 of msp-2 genes were genotyped by nested PCR. Overall, 57 genotypes with fragment sizes ranging from 110 to 410 bp were recorded for msp-1, among which 25, 21, and 11 genotypes identified for K1, MAD20, and RO33 allelic families respectively. RO33 (34.3%) and MAD20 (34.3%) allelic families were more frequent compared to K1 (31.4%) although the difference was not statistically significant. Also, 47 msp-2 genotypes were identified, including 26 FC27 genotypes type, and 21 genotypes belonging to the 3D7 allelic family. FC27 was more frequent (52.3%) compared to 3D7 (47.7%). The prevalence of the polyclonal infection was 90.0% while the MOI was 2.90 ± 1.0. The MOI and polyclonal infection were not significantly associated with the parasitaemia and anaemia. This study reveals a high genetic diversity and the trend of increasing MOI of P. falciparum isolates from the south of Brazzaville, compared to the reports from the same setting before the COVID-19 pandemic.

Early Circulation of SARS-CoV-2, Congo, 2020.

To determine when severe acute respiratory syndrome coronavirus 2 arrived in Congo, we retrospectively antibody tested 937 blood samples collected during September 2019-February 2020. Seropositivity significantly increased from 1% in December 2019 to 5.3% in February 2020, before the first officially reported case in March 2020, suggesting unexpected early virus circulation.

Plasmodium falciparum multiplicity of infection and pregnancy outcomes in Congolese women from southern Brazzaville, Republic of Congo.

BACKGROUND: Investigating whether the multiplicity of Plasmodium falciparum infection (MOI) is related to pregnancy outcomes, is of interest in sub-Saharan area where malaria is highly endemic. The present study aimed to characterize the genetic diversity of P. falciparum in women at delivery from Southern Brazzaville, and investigate whether the MOI is associated with maternal anaemia, preterm delivery, or low birth weight. METHODS: This was a cross sectional study carried out with samples collected between March 2014 and April 2015 from 371 women recruited at delivery at a Health Centre in southern Brazzaville, Republic of Congo. Matched peripheral, placental, and cord blood collected from each of the women at delivery were used for the detection of P. falciparum microscopic and submicroscopic parasitaemia, and parasite DNA genotyping by nested PCR. RESULTS: From 371 recruited women, 27 were positive to microscopic malaria parasitaemia while 223 women harboured submicroscopic parasitaemia. All msp-1 block 2 family allelic types (K1, MAD20 and RO33) were observed in all the three compartments of blood, with K1 being most abundant. K1 (with 12, 10, and 08 alleles in the peripheral, placental, and cord blood respectively) and MAD20 (with 10, 09, and 06 alleles in the respective blood compartments) were more diverse compared to RO33 (with 06, 06, and 05 alleles in the respective blood compartments). From the 250 women with microscopic and/or submicroscopic parasitaemia, 38.5%, 30.5%, and 18.4% of peripheral, placental and cord blood sample, respectively, harboured more than one parasite clone, and polyclonal infection was more prevalent in the peripheral blood of women with microscopic parasitaemia (54.5%) compared to those with submicroscopic parasitaemia (36.7%) (p = 0.02). The mean multiplicity of genotypes per microscopic and submicroscopic infection in peripheral blood was higher in anemic women (2.00 ± 0.23 and 1.66 ± 0.11, respectively) than in non-anaemic women (1.36 ± 0.15 and 1.45 ± 0.06, respectively) (p = 0.03 and 0.06). In logistic regression, women infected with four or more clones of the parasite were 9.4 times more likely to be anaemic than women harbouring one clone. This association, however, was only observed with the peripheral blood infection. No significant association was found between the MOI and low birth weight or preterm delivery. CONCLUSIONS: These results indicate that the genetic diversity of P. falciparum is high in pregnant women from southern Brazzaville in the Republic of Congo, and the multiplicity of the infection might represent a risk for maternal anaemia.

Child Mouthing of Feces and Fomites and Animal Contact are Associated with Diarrhea and Impaired Growth Among Young Children in the Democratic Republic of the Congo: A Prospective Cohort Study (REDUCE Program).

OBJECTIVE: To identify exposure pathways to fecal pathogens that are significant contributors to diarrheal diseases and impaired growth in young children, and to evaluate scalable interventions to reduce fecal contamination from these pathways. STUDY DESIGN: Reducing Enteropathy, Undernutrition, and Contamination in the Environment (REDUCE) was a prospective cohort study of 370 children <5 years of age was conducted in Walungu Territory, South Kivu, Democratic Republic of the Congo. Child mouthing behaviors were assessed through caregiver reports and 5-hour structured observations. Caregiver reports of child contact with animals and child diarrhea were also obtained. Anthropometric measurements were collected at baseline and at a 6-month follow-up. RESULTS: Children observed putting soil in their mouth during structured observation at baseline had a significantly higher odds of diarrhea at the 6-month follow-up (OR, 1.79; 95% CI, 1.04 to 3.07). Children observed mouthing feces during structured observation had a significant reduction in height-for-age z-score (HAZ) from baseline to the 6-month follow-up (ΔHAZ, -0.69; 95% CI, -1.34 to -0.04). A significant reduction in HAZ was also observed for children with caregiver reports of touching guinea pigs (-0.33; 95% CI, -0.58 to -0.08) and rabbits (-0.34; 95% CI, -0.64 to -0.04) and children with feces in their sleeping space during unannounced spot checks (-0.41; 95% CI, -0.74 to -0.09). CONCLUSIONS: These findings emphasize the urgent need for infant water, sanitation, and hygiene interventions targeting child mouthing behaviors, fecal contamination in child living spaces, and child contact with domestic animals to reduce exposure to fecal pathogens among susceptible populations.

Epidemiological profile of multidrug-resistant and extensively drug-resistant Mycobacterium Tubrculosis among Congolese patients.

BACKGROUND: There is paucity of data on the prevalence and distribution of multidrug- Resistant-Tuberculosis (MDR-TB) in the Republic of Congo. Among the challenges resides the implementation of a robust TB resistance diagnostic program using molecular tools. In resource limited settings there is a need to gather data to enable prioritization of actions. The objective of this study was is to implement molecular tools as a best of diagnosing MDR and XDR-TB among presumptive tuberculosis patients referred to reference hospital of Makelekele in Brazzaville, Republic of the Congo. METHODS: We have conducted a cross-sectional study, including a total of 92 presumptive pulmonary tuberculosis patients and who had never received treatment recruited at the reference hospital of Makelekele from October 2018 to October 2019. The socio-demographic and clinical data were collected as well as sputum samples. Rifampicin resistance was investigated using Xpert (Cepheid) and second-line TB drugs Susceptibility testing were performed by the Brucker HAIN Line Probe Assay (GenoType MTBDRsl VER 2.0 assay) method. RESULTS: From the 92 recruited patients, 57 (62%) were found positive for the Mycobacterium tuberculosis complex. The prevalence of rifampicin-resistant tuberculosis (RR-TB) was 9.8% (9/92) and importantly 2.2% were pre-XDR/XDR. CONCLUSION: This study showed a high rate of rifampicin resistance and the presence of extensively drug-resistant tuberculosis in the study area in new patients. This study highlights the need for further studies of TB drug resistance in the country.

Improvement of SCD morbimortality in children: experience in a remote area of an African country.

BACKGROUND: Sickle cell disease (SCD) is a public health problem in the Democratic Republic of Congo. While reference sickle cell centers have been implemented in capital cities of African countries and have proven to be beneficial for SCD patients. In the Democratic Republic of Congo, they have never been set up in remote areas for families with low or very low sources of income. METHOD: A cohort of 143 children with SCD aged 10 years old (IQR (interquartile range): 6-15 years) (sex ratio male/female = 1.3) were clinically followed for 12 months without any specific intervention aside from the management of acute events, and then for 12 months with a monthly medical visit, biological follow-up, and chemoprophylaxis (folic acid/penicillin), adequate fluids and malaria prevention. RESULTS: The median age of patients at the diagnosis of SCD was 2 years (IQR: 1-5). The implementation of standardized and regular follow-ups in a new sickle cell reference center in a remote city showed an increase in the annual mean hemoglobin level from 50 to 70 g/L (p = 0.001), and a decrease in the lymphocyte count and spleen size (p < 0.001). A significant decrease (p < 0.001) in the average annual number of hospitalizations and episodes of vaso-occlusive crises, blood transfusions, infections, and acute chest syndromes were also observed. CONCLUSIONS: The creation of a sickle cell reference center and the regular follow-up of children with sickle cell disease are possible and applicable in the context of a remote city of an African country and represent simple and accessible measures that can reduce the morbimortality of children with sickle cell disease.

Variation of prevalence of malaria, parasite density and the multiplicity of Plasmodium falciparum infection throughout the year at three different health centers in Brazzaville, Republic of Congo.

BACKGROUND: In the Republic of Congo, hot temperature and seasons distortions observed may impact the development of malaria parasites. We investigate the variation of malaria cases, parasite density and the multiplicity of Plasmodium falciparum infection throughout the year in Brazzaville. METHODS: From May 2015 to May 2016, suspected patients with uncomplicated malaria were enrolled at the Hôpital de Mfilou, CSI « Maman Mboualé¼, and the Laboratoire National de Santé Publique. For each patient, thick blood was examined and parasite density was calculated. After DNA isolation, MSP1 and MSP2 genes were genotyped. RESULTS: A total of 416, 259 and 131 patients with suspected malaria were enrolled at the CSI «Maman Mboualé¼, Hôpital de Mfilou and the Laboratoire National de Santé Publique respectively. Proportion of malaria cases and geometric mean parasite density were higher at the CSI «Maman Mboualé¼ compared to over sites (P-value <0.001). However the multiplicity of infection was higher at the Hôpital de Mfilou (P-value <0.001). At the Laboratoire National de Santé Publique, malaria cases and multiplicity of infection were not influenced by different seasons. However, variation of the mean parasite density was statistically significant (P-value <0.01). Higher proportions of malaria cases were found at the end of main rainy season either the beginning of the main dry season at the Hôpital de Mfilou and the CSI «Maman Mboualé¼; while, lowest proportions were observed in September and January and in September and March respectively. Higher mean parasite densities were found at the end of rainy seasons with persistence at the beginning of dry seasons. The lowest mean parasite densities were found during dry seasons, with persistence at the beginning of rainy seasons. Fluctuation of the multiplicity of infection throughout the year was observed without significance between seasons. CONCLUSION: The current study suggests that malaria transmission is still variable between the north and south parts of Brazzaville. Seasonal fluctuations of malaria cases and mean parasite densities were observed with some extension to different seasons. Thus, both meteorological and entomological studies are needed to update the season's periods as well as malaria transmission intensity in Brazzaville.

Current burden of serious fungal infections in Republic of Congo.

BACKGROUND: The Republic of Congo (RoC) is characterised by a high prevalence of tuberculosis and HIV/AIDS, which largely drive the epidemiology of serious fungal infections. OBJECTIVE: We aimed to estimate the current burden of serious fungal infections in RoC. MATERIAL AND METHODS: Using local, regional or global data and estimates of population and at-risk population groups, deterministic modelling was employed to estimate national incidence or prevalence of the most serious fungal infections. RESULTS: Our study revealed that about 5.4% of the Congolese population (283 450) suffer from serious fungal infections yearly. The incidence of cryptococcal meningitis, Pneumocystis jirovecii pneumonia and disseminated histoplasmosis in AIDS patients was estimated at 560, 830 and 120 cases per year. Oral and oesophageal candidiasis collectively affects 12 320 HIV-infected patients. Chronic pulmonary aspergillosis, 67% post-tuberculosis, probably has a prevalence of 3420. Fungal asthma (allergic bronchopulmonary aspergillosis and severe asthma with fungal sensitisation) probably has a prevalence of 3640 and 4800, although some overlap due to disease definition is likely. The estimated prevalence of recurrent vulvovaginal candidiasis and tinea capitis is 85 440 and 178 400 respectively. Mostly related to agricultural activity, fungal keratitis affects an estimated 700 Congolese yearly. CONCLUSION: These data underline the urgent need for an intensified awareness towards Congolese physicians to fungal infections and for increased efforts to improve diagnosis and management of fungal infections in the RoC.

"In Africa, There Was No Family Planning. Every Year You Just Give Birth": Family Planning Knowledge, Attitudes, and Practices Among Somali and Congolese Refugee Women After Resettlement to the United States.

It is crucial for refugee service providers to understand the family planning knowledge, attitudes, and practices of refugee women following third country resettlement. Using an ethnographic approach rooted in Reproductive Justice, we conducted six focus groups that included 66 resettled Somali and Congolese women in a western United States (US) metropolitan area. We analyzed data using modified grounded theory. Three themes emerged within the family planning domain: (a) concepts of family, (b) fertility management, and (c) unintended pregnancy. We contextualized these themes within existing frameworks for refugee cultural transition under the analytic paradigms of "pronatalism and stable versus evolving family structure" and "active versus passive engagement with family planning." Provision of just and equitable family planning care to resettled refugee women requires understanding cultural relativism, social determinants of health, and how lived experiences influence family planning conceptualization. We suggest a counseling approach and provider practice recommendations based on our study findings.

Epidemiologic and Ecologic Investigations of Monkeypox, Likouala Department, Republic of the Congo, 2017.

Monkeypox, caused by a zoonotic orthopoxvirus, is endemic in Central and West Africa. Monkeypox has been sporadically reported in the Republic of the Congo. During March 22-April 5, 2017, we investigated 43 suspected human monkeypox cases. We interviewed suspected case-patients and collected dried blood strips and vesicular and crust specimens (active lesions), which we tested for orthopoxvirus antibodies by ELISA and monkeypox virus and varicella zoster virus DNA by PCR. An ecologic investigation was conducted around Manfouété, and specimens from 105 small mammals were tested for anti-orthopoxvirus antibodies or DNA. Among the suspected human cases, 22 met the confirmed, probable, and possible case definitions. Only 18 patients had available dried blood strips; 100% were IgG positive, and 88.9% (16/18) were IgM positive. Among animals, only specimens from Cricetomys giant pouched rats showed presence of orthopoxvirus antibodies, adding evidence to this species' involvement in the transmission and maintenance of monkeypox virus in nature.

High prevalence of norovirus and rotavirus co-infection in children with acute gastroenteritis hospitalised in Brazzaville, Republic of Congo.

OBJECTIVE: To evaluate the clinical severity of diarrhoea associated to viral co-infection in children with acute gastroenteritis. METHODS: About 461 children under five years hospitalised with acute diarrhoea (266 males and 187 females) were enrolled in the study. Using stool samples, rotavirus and adenovirus infections were investigated by ELISA, and norovirus infections by nested duplex RT-PCR. We assessed social, demographic, clinical and behavioural conditions that might influence the occurrence of rotavirus, adenovirus and norovirus infections. RESULTS: Mono-viral infection was detected in 49% and mixed viral infection in 12% of patients. The prevalence of mixed infection was neither dependent on age nor sex. Three samples were infected with all three viruses. A significant association was found between fever (axillary temperature> 37.5 °C) and rotavirus-norovirus dual infection (aOR (CI 95%) = 2.1 (1.14-3.84), P = 0.016; aOR (CI 95%) = 0.37 (0.19-0.73), P = 0.004). Mixed infection was the most common during the dry season from June to October (71.4% versus 54.7%, P = 0.023). CONCLUSION: Co-infection with both rotavirus and norovirus is common in under-five hospitalised children but does not contribute to the severity of the disease.

OBJECTIF: Evaluer la sévérité clinique de la diarrhée associée à la coinfection virale chez les enfants atteints de gastroentérite aiguë. MÉTHODES: 461 enfants de moins de cinq ans hospitalisés pour une diarrhée aiguë (266 garçons et 187 filles) ont été inclus dans l'étude. Sur des échantillons de selles, les infections à rotavirus et à adénovirus ont été investiguées par ELISA et les infections à norovirus par RT-PCR duplex imbriqué. Nous avons évalué les conditions sociales, démographiques, cliniques et comportementales susceptibles d'influencer la survenue d'infections à rotavirus, adénovirus et norovirus. RÉSULTATS: Une infection mono virale a été détectée chez 49% des patients et une infection virale mixte chez 12% des patients. La prévalence des infections mixtes ne dépendait ni de l'âge ni du sexe. Trois échantillons étaient infectés par tous les trois virus. Une association significative a été observée entre la fièvre (température axillaire > 37,5 °C) et la double infection rotavirus-norovirus (aOR (IC95%) = 2,1 (1,14-3,84), P = 0,016; aOR (IC95%) = 0,37 (0,19-0,73), P = 0,004). Les infections mixtes étaient les plus courantes pendant la saison sèche de juin à octobre (71,4% contre 54,7%, P = 0,023). CONCLUSION: La coinfection à la fois par le rotavirus et par le norovirus est fréquente chez les enfants de moins de cinq ans hospitalisés, mais ne contribue pas à la sévérité de la maladie.

Testosterone, fathers as providers and caregivers, and child health: Evidence from fisher-farmers in the Republic of the Congo.

Males in vertebrate species with biparental care commonly face a life history trade-off between investing in mating versus parenting effort. Among these males, testosterone is frequently elevated during mating and competition and reduced when males help raise offspring. These physiological patterns may be adaptive, increasing males' fitness through investments in young. However, for some species, including humans, indirect parenting often benefits young but can also involve male competition and risk-taking behavior and may be facilitated by elevated testosterone. Despite potential adaptive functions of biological responses to invested fatherhood, few if any mammalian studies have linked fathers' testosterone to offspring outcomes; no studies in humans have. Using data from a small-scale society of fisher-farmers from the Republic of the Congo, we find that fathers who were rated as better providers by their peers had higher testosterone, compared to other fathers in their community. However, children whose fathers had middle-range T compared to fathers with higher or lower levels had better energetic status (higher BMI; greater triceps skinfold thickness). Fathers' indirect and direct care helped to account for these associations between paternal T and children's energetic profiles. Given that human paternal direct and, especially, indirect care are thought to have been important evolutionarily and remain so in many contemporary societies, these findings help to shed light on the facultative nature of human biological responses to fatherhood and the relevance of these factors to children's well-being.

A Mixed-Method Design Evaluation of the SAFE Obstetric Anaesthesia Course at 4 and 12-18 Months After Training in the Republic of Congo and Madagascar.

BACKGROUND: Maternal mortality in low- and middle-income countries (LMICs) is higher than in high-income countries (HICs), and poor anesthesia care is a contributing factor. Many anesthesia complications are considered preventable with adequate training. The Safer Anaesthesia From Education Obstetric Anaesthesia (SAFE-OB) course was designed as a refresher course to upgrade the skills of anesthesia providers in low-income countries, but little is known about the long-term impact of the course on changes in practice. We report changes in practice at 4 and 12-18 months after SAFE-OB courses in Madagascar and the Republic of Congo. METHODS: We used a concurrent embedded mixed-methods design based on the Kirkpatrick model for evaluating educational training courses. The primary outcome was qualitative determination of personal and organizational change at 4 months and 12-18 months. Secondary outcomes were quantitative evaluations of knowledge and skill retention over time. From 2014 to 2016, 213 participants participated in 5 SAFE-OB courses in 2 countries. Semistructured interviews were conducted at 4 and 12-18 months using purposive sampling and analyzed using thematic content analysis. Participants underwent baseline knowledge and skill assessment, with 1 cohort reevaluated using repeat knowledge and skills tests at 4 months and another at 12-18 months. RESULTS: At 4 months, 2 themes of practice change (Kirkpatrick level 3) emerged that were not present at 12-18 months: neonatal resuscitation and airway management. At 12-18 months, 4 themes emerged: management of obstetric hemorrhage, management of eclampsia, using a structured approach to assessing a pregnant woman, and management of spinal anesthesia. With respect to organizational culture change (Kirkpatrick level 4), the same 3 themes emerged at both 4 and 12-18 months: improved teamwork, communication, and preparation. Resistance from peers, lack of senior support, and lack of resources were cited as barriers to change at 4 months, but at 12-18 months, very few interviewees mentioned lack of resources. Identified catalysts for change were self-motivation, credibility, peer support, and senior support. Knowledge and skills tests both showed an immediate improvement after the course that was sustained. This supports the qualitative responses suggesting personal and organizational change. CONCLUSIONS: Participation at a SAFE-OB course in the Republic of Congo and in Madagascar was associated with personal and organizational changes in practice and sustained improvements in knowledge and skill at 12-18 months.

A new look at population health through the lenses of cognitive, functional and social disability clustering in eastern DR Congo: a community-based cross-sectional study.

BACKGROUND: The importance of viewing health from a broader perspective than the mere presence or absence of disease is critical at primary healthcare level. However, there is scanty evidence-based stratification of population health using other criteria than morbidity-related indicators in developing countries. We propose a novel stratification of population health based on cognitive, functional and social disability and its covariates at primary healthcare level in DR Congo. METHOD: We conducted a community-based cross-sectional study in adults with diabetes or hypertension, mother-infant pairs with child malnutrition, their informal caregivers and randomly selected neighbours in rural and sub-urban health zones in South-Kivu Province, DR Congo. We used the WHO Disability Assessment Schedule 2.0 (WHODAS) to measure functional, cognitive and social disability. The study outcome was health status clustering derived from a principal component analysis with hierarchical clustering around the WHODAS domains scores. We calculated adjusted odds ratios (AOR) using mixed-effects ordinal logistic regression. RESULTS: Of the 1609 respondents, 1266 had WHODAS data and an average age of 48.3 (SD: 18.7) years. Three hierarchical clusters were identified: 9.2% of the respondents were in cluster 3 of high dependency, 21.1% in cluster 2 of moderate dependency and 69.7% in cluster 1 of minor dependency. Associated factors with higher disability clustering were being a patient compared to being a neighbour (AOR: 3.44; 95% CI: 1.93-6.15), residency in rural Walungu health zone compared to semi-urban Bagira health zone (4.67; 2.07-10.58), female (2.1; 1.25-2.94), older (1.05; 1.04-1.07), poorest (2.60; 1.22-5.56), having had an acute illness 30 days prior to the interview (2.11; 1.24-3.58), and presenting with either diabetes or hypertension (2.73; 1.64-4.53) or both (6.37; 2.67-15.17). Factors associated with lower disability clustering were being informally employed (0.36; 0.17-0.78) or a petty trader/farmer (0.44; 0.22-0.85). CONCLUSION: Health clustering derived from WHODAS domains has the potential to suitably classify individuals based on the level of health needs and dependency. It may be a powerful lever for targeting appropriate healthcare service provision and setting priorities based on vulnerability rather than solely presence of disease.
