Associations between the stringency of COVID-19 containment policies and health service disruptions in 10 countries.

BACKGROUND: Disruptions in essential health services during the COVID-19 pandemic have been reported in several countries. Yet, patterns in health service disruption according to country responses remain unclear. In this paper, we investigate associations between the stringency of COVID-19 containment policies and disruptions in 31 health services in 10 low- middle- and high-income countries in 2020. METHODS: Using routine health information systems and administrative data from 10 countries (Chile, Ethiopia, Ghana, Haiti, Lao People's Democratic Republic, Mexico, Nepal, South Africa, South Korea, and Thailand) we estimated health service disruptions for the period of April to December 2020 by dividing monthly service provision at national levels by the average service provision in the 15 months pre-COVID (January 2019-March 2020). We used the Oxford COVID-19 Government Response Tracker (OxCGRT) index and multi-level linear regression analyses to assess associations between the stringency of restrictions and health service disruptions over nine months. We extended the analysis by examining associations between 11 individual containment or closure policies and health service disruptions. Models were adjusted for COVID caseload, health service category and country GDP and included robust standard errors. FINDINGS: Chronic disease care was among the most affected services. Regression analyses revealed that a 10% increase in the mean stringency index was associated with a 3.3 percentage-point (95% CI -3.9, -2.7) reduction in relative service volumes. Among individual policies, curfews, and the presence of a state of emergency, had the largest coefficients and were associated with 14.1 (95% CI -19.6, 8.7) and 10.7 (95% CI -12.7, -8.7) percentage-point lower relative service volumes, respectively. In contrast, number of COVID-19 cases in 2020 was not associated with health service disruptions in any model. CONCLUSIONS: Although containment policies were crucial in reducing COVID-19 mortality in many contexts, it is important to consider the indirect effects of these restrictions. Strategies to improve the resilience of health systems should be designed to ensure that populations can continue accessing essential health care despite the presence of containment policies during future infectious disease outbreaks.

Tracking health system performance in times of crisis using routine health data: lessons learned from a multicountry consortium.

COVID-19 has prompted the use of readily available administrative data to track health system performance in times of crisis and to monitor disruptions in essential healthcare services. In this commentary we describe our experience working with these data and lessons learned across countries. Since April 2020, the Quality Evidence for Health System Transformation (QuEST) network has used administrative data and routine health information systems (RHIS) to assess health system performance during COVID-19 in Chile, Ethiopia, Ghana, Haiti, Lao People's Democratic Republic, Mexico, Nepal, South Africa, Republic of Korea and Thailand. We compiled a large set of indicators related to common health conditions for the purpose of multicountry comparisons. The study compiled 73 indicators. A total of 43% of the indicators compiled pertained to reproductive, maternal, newborn and child health (RMNCH). Only 12% of the indicators were related to hypertension, diabetes or cancer care. We also found few indicators related to mental health services and outcomes within these data systems. Moreover, 72% of the indicators compiled were related to volume of services delivered, 18% to health outcomes and only 10% to the quality of processes of care. While several datasets were complete or near-complete censuses of all health facilities in the country, others excluded some facility types or population groups. In some countries, RHIS did not capture services delivered through non-visit or nonconventional care during COVID-19, such as telemedicine. We propose the following recommendations to improve the analysis of administrative and RHIS data to track health system performance in times of crisis: ensure the scope of health conditions covered is aligned with the burden of disease, increase the number of indicators related to quality of care and health outcomes; incorporate data on nonconventional care such as telehealth; continue improving data quality and expand reporting from private sector facilities; move towards collecting patient-level data through electronic health records to facilitate quality-of-care assessment and equity analyses; implement more resilient and standardized health information technologies; reduce delays and loosen restrictions for researchers to access the data; complement routine data with patient-reported data; and employ mixed methods to better understand the underlying causes of service disruptions.

ECD - Pregnancy outcomes of a birth cohort. Are adolescent mothers really at more risk?

This sub-study within the JAKIDS longitudinal cohort study compares medical and psychosocial outcomes of pregnancy in younger adolescent mothers (<16 years), older adolescent mothers (16-19 years) and adult mothers (>19 years) in Jamaica. Participants were recruited from July to September 2011 and included 9521 mother-infant dyads; mean maternal age 26.0 years (SD 6.8). Adolescent mothers represented 19.1% (n = 1822) of the sample - 1704 older adolescent mothers (17.9%) and 118 younger adolescent mothers (1.2%). Participants completed interviewer-administered questionnaires regarding their sexual and reproductive health history, feelings about the current pregnancy, and presence of anxious and depressive symptoms. Data on delivery and perinatal and neonatal outcomes were extracted from hospital charts. Younger adolescent mothers were more likely to deliver preterm (p < 0.001) and low birth weight infants (p < 0.001) than older adolescent and adult mothers. Younger adolescent mothers had lower levels of antenatal anxiety regarding the pregnancy and its outcome (p < 0.001) while prevalence of elevated depressive symptoms antenatally (EPDS ≥11) was similar across age groups. Older adolescent mothers with significant depressive symptoms had increased odds of preterm delivery. These findings call for close antenatal monitoring of younger adolescent mothers and highlight the need for psychological services for all mothers.

Assessment of Interrater Reliability of the Emergency Severity Index After Implementation in Emergency Departments in Jamaica Using a Learning Collaborative Approach.

INTRODUCTION: In 2016, the Ministry of Health in Jamaica selected the Emergency Severity Index as the triage tool to be used nationally. This study evaluated the effectiveness of this approach by assessing the interrater reliability among new users trained with minimal resources by 2 experienced trainers, 1 local and 1 international. METHODS: A retrospective case series review was conducted within an online learning collaborative framework. After completion of the training, the participants from each of the 19 clinical sites were asked to submit 2 triage cases per month for blinded review by the expert trainers. The triage categories assigned by each reviewer were compared with those assigned by the newly trained Emergency Severity Index providers. A weighted kappa value was calculated to assess the degree of agreement between the sites and the expert trainers. RESULTS: A total of 166 cases were received over the study period. Participation in the learning collaborative was consistently below 50%. The interrater reliability between the expert trainers (κ = 0.48) as well as between each scorer and each accident and emergency department site (κSF = 0.33, κPT = 0.26) was low, although there was improvement over the study period. Incomplete triage documentation limited raters' ability to assign triage categories and assess interrater reliability. DISCUSSION: Despite a rigorous implementation process, the interrater reliability of the Emergency Severity Index skills of Jamaican emergency nurses and doctors when compared with that of the 2 experts was poor. Several areas were identified for strengthening. Considerations for the implementation of the Emergency Severity Index in countries outside of the US were also discussed.

Richer but fatter: the unintended consequences of microcredit financing on household health and expenditure in Jamaica.

OBJECTIVE: To determine whether there was a difference in wealth and cardiovascular disease (CVD) risk between microcredit loan beneficiaries and community-matched non-beneficiaries (controls). METHODS: Seven hundred and twenty-six households of microcredit loan beneficiaries were matched with 726 controls by age, sex and community. A standardised interviewer administered questionnaire was used to collect data on health and household expenditure. Weights, heights, waist circumference and blood pressure measurements were taken for an adult and one child (6-16 years) from each household. RESULTS: Amongst adults, there was no difference in the prevalence of pre-hypertension and hypertension. More male (68.1% vs. 47.8%) and female beneficiaries (84.5% vs. 77.9%) were overweight/obese. More male (17.2% vs. 7.1%; P < 0.05) and female beneficiaries (68.5% vs. 63.3%; P < 0.05) exhibited substantially increased risk for CVD. Children of beneficiaries displayed higher mean BMI-for-age z-scores than their control peers: males 0.56 [95% CI 0.40-0.72] vs. 0.18 [95% CI 0.02-0.35] (P < 0.001) and females 0.66 [95% CI 0.52-0.80] vs. 0.42 [95% CI 0.29-0.56] (P < 0.001). Based on BMI-for-age z-scores, children of beneficiaries had greater odds of being overweight/obese (OR = 1.46; 95% CI 1.18-1.82) Beneficiaries were economically better off; their mean total annual expenditure and house ownership were significantly higher than controls (P < 0.001). CONCLUSIONS: Microcredit financing is positively associated with wealth acquisition but worsened cardiovascular risk status.

Diabetes mellitus in Jamaica: sex differences in burden, risk factors, awareness, treatment and control in a developing country.

OBJECTIVE: The objective of this study was to provide valid estimates of the burden of and risk factors for diabetes mellitus by sex in Jamaica, a predominantly Black, middle-income and developing country. METHODS: The Jamaica Health and Lifestyle Survey 2008 examined a nationally representative sample of 2848 Jamaicans aged 15-74. Parameter estimates and 95% confidence intervals [CI] were weighted for non-response as well as age and sex of the source population. Sex differences in risk factors and diabetes prevalence, awareness, treatment and control were estimated in multivariable models. Population-attributable fractions (PAFs) of obesity on diabetes mellitus were estimated in both sexes. RESULTS: The prevalence of diabetes mellitus was 7.9% (95% CI: 6.7-9.1%), significantly higher in women than men 9.3% vs. 6.4% (P = 0.02) and increasing with age. Seventy-six percentage of persons with diabetes mellitus were aware of their status; urban women and rural men were less likely to be aware. Diabetes control (43% overall) was less common in higher-income men, but more common in higher-income women. Persons without health insurance were less likely to control their diabetes. The prevalence of diabetes risk factors was higher in women than men. Increased waist circumference (≥94 cm [men]/≥80 cm [women]), overweight/obesity (body mass index ≥ 25 kg/m(2)) and low physical activity/inactivity were associated with PAFs for diabetes mellitus of 27%, 37% and 15%, respectively, in men and 77%, 54% and 24%, respectively, in women. CONCLUSIONS: Prevalence of diabetes mellitus and its risk factors is high in Jamaica, especially among women, and national programmes to stem the diabetes mellitus epidemic should take these sex differences into consideration.

Severity and Outcomes of Dengue in Hospitalized Jamaican Children in 2018-2019 During an Epidemic Surge in the Americas.

Objective: In 2019, dengue was among the "top-ten threats to global health," with 3.1 million cases reported from the Americas, the highest ever. Simultaneously, Jamaica reported its largest dengue outbreak in 40 years, following Chikungunya and Zika virus epidemics, in 2014 and 2016-2017, respectively. We describe dengue in children admitted to five hospitals in Jamaica during August 2018 through September 2019. Methods: Hospitalized children and adolescents aged 0 to 15 years with dengue were managed using PAHO/WHO criteria. Data were extracted from questionnaires, entered into a dataset on Microsoft Excel version 2016, exported to SPSS version 20 and analyzed. Groups were compared using Student's t-test for normally distributed parametric data. Chi-square analysis, or Fisher's exact test was used for categorical variables. A p-value < 0.05 was considered statistically significant. Results: There were 339 children, 245 (72.3%) aged 1-10 years, males:females 1:1. Classification was "dengue without warning signs" 53 (15.3%), "dengue with warning signs" 218 (64.3%) and "severe dengue" 68 (20%). Co-morbidities were reported in 88 (26%). Hemoglobin SC disease was associated with severe dengue with hemorrhage (p = 0.005). Organ-system involvement occurred in 334 (98.5%) including gastrointestinal 317 (93.5%), hematologic 311 (91.7%) and musculoskeletal 180 (53.1%). Thirty-nine (11.5%) had 5-7 organ-systems involved. Metabolomics emphasized increased hepatic transaminases 245 (72.3%), lactate dehydrogenase 164 (48.4%) and creatine phosphokinase 84 (24.8%) approaching the high thousands (121,560 u/L), both were markers for severe disease (p < 0.002). Thirteen (3.8%) received intensive care. Dengue was laboratory-confirmed in 220 (78.9%): NS1 antigen-positive (218); RT-PCR-positive (23), with an overlap of NS1 antigen and RT-PCR positive (21); DENV-3 serotype (20). Seventeen (5%) died, 16 (94.1%) had severe dengue and 11 (64.7%) succumbed within 24 to 48 h of admission despite resuscitation and transfusion of blood products. Conclusion: Severe dengue with increased attributable mortality occurred in hospitalized children after Jamaica's maiden Zika epidemic.

COVID-19 and resilience of healthcare systems in ten countries.

Declines in health service use during the Coronavirus Disease 2019 (COVID-19) pandemic could have important effects on population health. In this study, we used an interrupted time series design to assess the immediate effect of the pandemic on 31 health services in two low-income (Ethiopia and Haiti), six middle-income (Ghana, Lao People's Democratic Republic, Mexico, Nepal, South Africa and Thailand) and high-income (Chile and South Korea) countries. Despite efforts to maintain health services, disruptions of varying magnitude and duration were found in every country, with no clear patterns by country income group or pandemic intensity. Disruptions in health services often preceded COVID-19 waves. Cancer screenings, TB screening and detection and HIV testing were most affected (26-96% declines). Total outpatient visits declined by 9-40% at national levels and remained lower than predicted by the end of 2020. Maternal health services were disrupted in approximately half of the countries, with declines ranging from 5% to 33%. Child vaccinations were disrupted for shorter periods, but we estimate that catch-up campaigns might not have reached all children missed. By contrast, provision of antiretrovirals for HIV was not affected. By the end of 2020, substantial disruptions remained in half of the countries. Preliminary data for 2021 indicate that disruptions likely persisted. Although a portion of the declines observed might result from decreased needs during lockdowns (from fewer infectious illnesses or injuries), a larger share likely reflects a shortfall of health system resilience. Countries must plan to compensate for missed healthcare during the current pandemic and invest in strategies for better health system resilience for future emergencies.

Household food insecurity and childhood overweight in Jamaica and Québec: a gender-based analysis.

BACKGROUND: Childhood overweight is not restricted to developed countries: a number of lower- and middle-income countries are struggling with the double burden of underweight and overweight. Another public health problem that concerns both developing and, to a lesser extent, developed countries is food insecurity. This study presents a comparative gender-based analysis of the association between household food insecurity and overweight among 10-to-11-year-old children living in the Canadian province of Québec and in the country of Jamaica. METHODS: Analyses were performed using data from the 2008 round of the Québec Longitudinal Study of Child Development and the Jamaica Youth Risk and Resiliency Behaviour Survey of 2007. Cross-sectional data were obtained from 1190 10-year old children in Québec and 1674 10-11-year-old children in Jamaica. Body mass index was derived using anthropometric measurements and overweight was defined using Cole's age- and sex-specific criteria. Questionnaires were used to collect data on food insecurity. The associations were examined using chi-square tests and multivariate regression models were used to estimate odds ratios (OR) and 95% confidence intervals. RESULTS: The prevalence of overweight was 26% and 11% (p < 0.001) in the Québec and Jamaican samples, respectively. In Québec, the adjusted odds ratio for being overweight was 3.03 (95% CI: 1.8-5.0) among children living in food-insecure households, in comparison to children living in food-secure households. Furthermore, girls who lived in food-insecure households had odds of 4.99 (95% CI: 2.4-10.5) for being overweight in comparison to girls who lived in food-secure households; no such differences were observed among boys. In Jamaica, children who lived in food-insecure households had significantly lower odds (OR 0.65, 95% CI: 0.4-0.9) for being overweight in comparison to children living in food-secure households. No gender differences were observed in the relationship between food-insecurity and overweight/obesity among Jamaican children. CONCLUSIONS: Public health interventions which aim to stem the epidemic of overweight/obesity should consider gender differences and other family factors associated with overweight/obesity in both developed and developing countries.

Adolescent health screening practices by physicians in Jamaica.

OBJECTIVE: To review Jamaican physicians' adolescent health screening practices by determining their frequency in areas of biomedical, psychological, social, and educational health; the factors that influence these practices; and physicians' perceived level of self-efficacy and their awareness of screening tools and guidelines. METHODS: A questionnaire was mailed to general practitioners, family medicine specialists, and pediatricians in Jamaica. The primary outcome variable was the frequency of physician screening for a range of biomedical, psychosocial, and educational developmental issues in the majority (≥ 50%) of adolescent patients. Bivariate analyses were performed to determine differences between professional groups. RESULTS: The response rate was 32.3% (n = 213), with 209 responders being suitable for further analysis. The sample comprised 48.8% general practitioners, 33.0% family medicine specialists, and 18.2% pediatricians. Physicians more often screened for biomedical risks than for psychosocial risks, with very low frequencies of screening for psychosocial issues such as mood, suicidal ideation, sexual orientation, and safety concerns. Physicians reported high levels of confidence in discussing most psychosocial issues with adolescent patients. Time limitation and an insufficient knowledge base were the main factors identified as influencing screening practices. CONCLUSIONS: The data suggest unsatisfactory frequency of adolescent health screening by Jamaican physicians, in particular for psychosocial factors. The primary factors identified by physicians as influencing their screening practices have potential for improvement through continued medical education.

Sickle Cell Disease and Pain: Is it all Vaso-occlusive Crises?

OBJECTIVES: Acute pain is the main complication of sickle cell disease. Chronic pain (CP) and neuropathic pain (NP) may also be experienced, but have not been formally described in Jamaican patients. A cross-sectional study was conducted to determine their prevalence and characteristics, and to determine the common pain locations and modalities of management. MATERIALS AND METHODS: All well individuals with sickle cell disease patients 14 years and older, not pregnant and without a history of clinical stroke were consecutively recruited. Anthropometric measurements, hematology studies, an analgesia checklist, and the Adult Sickle Cell Quality of Life Measurement Information System questionnaire were completed. The painDETECT questionnaire was completed to describe NP and pain patterns-from which CP was defined. RESULTS: There were 257 patients in total, with 55.6% being females; the mean age of the patients was 31.7±12 years, and 75% had the SS genotype. Almost all patients (92.6%) had had an acute pain crisis in their lifetime and 72.4% in the last year. The mean severity at last attack was 6.8±3.1 on a scale of 0 to 10. The prevalences of CP and NP were 21.5% and 17.9%, respectively. Female sex, the presence of current leg ulcers, and the use of a strong opioid in the last 4 weeks produced higher odds of NP, whereas older age, milder genotypes, and daily analgesic use had the highest odds of CP. Opioids were used by 40.1% of the patients in the previous 4 weeks, whereas nonpharmacological treatments such as physiotherapy was less used, but reported to be very effective. DISCUSSION: CP and NP should be assessed during routine care of sickle cell pain so that targeted therapies can be applied.

Sexual Abuse and Sexually-Transmitted HIV/AIDS in Jamaican Children and Adolescents Aged 6-19 Years.

INTRODUCTION: Risk factors and outcomes of sexually-acquired human immunodeficiency virus infection were characterized in Jamaican children and adolescents. METHODOLOGY: Management was carried out by multidisciplinary teams in Infectious Diseases clinics during August 2003 through February 2019 using modified World Health Organization HIV criteria. RESULTS: There were 78 clients, aged 6 to 19 years, with females:males = 4:1 (p < 0.05). Sexual-initiation occurred in 60%, 47 before < 16 years (median 13 years, with four < 10 years; females:males = 7:1). Sexual-initiation preceded HIV diagnosis in all cases (median 2 years). Secondary education 93% (69/77) and living with non-parental relatives 17% (13/78) were associated with early sexual-initiation (p < 0.042); as was later imprisonment in 6% (3/52). Other sexually transmitted infections 36% (19/53) were associated with sexual-initiation ≥ 16 years (p < 0.01). Risks for ongoing HIV-transmission included infrequent condom use 74% (39/53), body-piercings 50% (24/48), illicit drug use 37% (28/76), tattoos 36% (19/52), transactional sex 14% (7/53) and pregnancy 56% of girls. 77% (59/77) had Centres for Diseases Control's Category A HIV infection; 82% (61/75) initiated anti-retroviral therapy; 75% (56/75) had first-line drugs, with helper T lymphocyte counts ≥ 500 cells/µL in 61% (48/78) and HIV viral load of < 1,000 copies/µL in 63% (40/64). Complications included dermatological 39% (20/52), respiratory 25% (13/52) and neurological 15% (8/52). Early sexual initiation was associated with depression 43% (33/76; p < 0.004) and suicidal attempt or ideation 23% (18/77; p < 0.096). Four (5%) died. CONCLUSIONS: Sexually transmitted HIV/AIDS in children and adolescents should preempt prompt medical, legal and psychosocial interventions.

How Free Is Free Health Care? An Assessment of Universal Health Coverage Among Jamaicans with Sickle Cell Disease.

Purpose: In an effort to transition toward universal health coverage (UHC), Jamaica abolished user fees at all public health facilities in 2008. We aimed to determine the extent of out-of-pocket payments (OPPs) and the other cost barriers to UHC among patients with sickle cell disease (SCD). Methods: Patients presenting to the Sickle Cell Unit in Kingston, Jamaica, for routine care between October 2019 and August 2020 were consecutively recruited and interviewed about their latest hospitalization within the previous 4 weeks. Parents or guardians completed the questionnaire on behalf of pediatric patients. The questionnaire included the Patient Satisfaction Questionnaire Short Form (PSQ)-18 and the health module of the Jamaica Survey of Living Conditions. Results: There were 103 patients with ages ranging from 7 months to 56 years (51.5% female, 60.2% public hospitalizations, and 54.4% pediatric). The modal income (J$6200-$11,999 per week) was similar to the minimum wage and 48.5% lived in overcrowded households. Government drug-subsidy cards were owned by 39.8%. OPPs were made by 19.4% of persons for items and tests that were unavailable at public facilities. There were no costs reported by 69.6%, who visited public pharmacies. Similarly, the cost of admission to public hospitals was free for 95.4% of subjects. Using public transportation, private hospitalization, and having more disease complications were predictive of a perception that health care is unaffordable. Conclusion: Most SCD subjects reported no expense with public hospitalizations; however, approximately one in five reported OPPs. Efforts are needed to increase the availability of subsidized items, and the use of drug-subsidy cards, to improve UHC.

Health-related quality of life and neuropathic pain in sickle cell disease in Jamaica.

BACKGROUND: Health related quality of Life (HRQOL) is an important consideration when managing chronic diseases, like sickle cell disease (SCD). Assessment of neuropathic pain (NP) and its association with HRQOL in SCD are rarely reported. OBJECTIVES: To examine the prevalence of NP and its association with HRQOL in adult Jamaicans with SCD. METHODS: Adult SCD patients were recruited consecutively and data were collected on socio-demographics, NP using Douleur Neuropathique 4 (DN4), and HRQOL using the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me). Means, medians, t-tests, ANOVA tests, Wilcoxon Rank-sum tests, Kruskal-Wallis tests, Pearson's correlation and multivariate linear regression analyses were performed using STATA 14.2. RESULTS: There were 236 respondents, with 56.8% female, mean age 33.2 years (SD: 11.6; range: 18-67 years), and 75% had homozygous SS genotype. NP was likely present in 26.7% of the population. The standardized ASCQ-Me (mean ± SD; ordered from lowest to best HRQOL domain scores) were: emotional impact 53.3 ± 10.1; sleep impact 56.1 ± 9.7; social function 57.7 ± 10.6; pain impact 58.6 ± 7.8; and stiffness impact 61.0 ± 7.3. On multivariate analyses, NP significantly reduced emotional and social functioning and worsened sleep and stiffness. Higher acute pain scores significantly worsened all HRQOL domains, while higher disease severity worsened all except stiffness. Obesity was associated with worse sleep and greater stiffness. Females with leg ulcers reported lower social functioning and unemployed females had greater pain impact. CONCLUSIONS: NP is increasingly prevalent in SCD and worsens HRQOL. Gender specific studies are needed to understand the significantly poorer HRQOL in women.

Challenges in the control of neglected insect vector diseases of human importance in the Anglo-Caribbean.

INTRODUCTION: Neglected tropical diseases (NTDs) in developing countries like the Caribbean, negatively affect multiple income-generating sectors, including the tourism industry upon which island states are highly dependent. Insect-transmitted NTDs include, but are not limited to, malaria, dengue and lymphatic filariasis. Control measures for these disease, are often ignored because of the associated cost. Many of the developing country members are thus retained in a financially crippling cycle, balancing the cost of prophylactic measures with that of controlling an outbreak.The purpose of the paper is to bring awareness to NTDs transmitted by insects of importance to humans, and to assess factors affecting such control, in the English-speaking Caribbean. METHOD: Comprehensive literature review on reports pertaining to NTDs transmitted by insects in the Caribbean and Latin America was conducted. Data search was carried out on PubMed, and WHO and PAHO websites. RESULTS AND CONCLUSION: Potential risk factors for NTDs transmitted by arthropods in the English-speaking Caribbean are summarised. The mosquito appears to be the main insect-vector of human importance within the region of concern. Arthropod-vectors of diseases of veterinary importance are also relevant because they affect the livelihood of farmers, in highly agriculture based economies. Other NTDs may also be in circulation gauged by the presence of antibodies in Caribbean individuals. However, routine diagnostic tests for specific diseases are expensive and tests may not be conducted when diseases are not prevalent in the population. It appears that only a few English-speaking Caribbean countries have examined secondary reservoirs of pathogens or assessed the effectivity of their insect control methods. As such, disease risk assessment appears incomplete. Although continuous control is financially demanding, an integrated and multisectoral approach might help to deflect the cost. Such interventions are now being promoted by health agencies within the region and various countries are creating and exploring the use of novel tools to be incorporated in their insect-vector control programmes.
