Background: Chikungunya virus (CHIKV) entered the Caribbean for the first time in 2013 and Jamaica experienced its maiden epidemic with Chikungunya Fever in 2014. We aimed to describe the public health effects and describe the clinical features in children and adolescents in Jamaica. Methods: This study reviewed the public health effects of the illness in Jamaica by reviewing available data sources and the clinical features in 210 children and adolescents meeting the case definition at two hospitals, Bustamante Hospital for Children and University Hospital of the West Indies between August 23 and October 31, 2014 by chart review. Descriptive analyses and comparisons between groups using the Mann-Whitney U test were performed with SPSS version 22. Results: The majority of households were affected by the illness which caused widespread absenteeism from school and work, loss of productivity and economic losses estimated at 60 billion dollars. The health sector was impacted by increased numbers seen in clinics and emergency departments, increased need for bed space and pharmaceuticals. Ninety-nine per cent of the children were febrile with a median maximal temperature of 102.4 F. Ninety-three per cent had household contacts of 0-20 persons. In addition to fever, maculopapular rash and joint pains, infants six months and younger presented with irritability and groaning (p = 0.00) and those between six months and six years presented with febrile seizures (p = 0.00). Neurologic involvement was noted in 24%. Apart from anaemia, few had other laboratory derangements. Few had severe organ dysfunction and there were no deaths. Conclusion: The Chikungunya Fever epidemic had significant public health and economic impact in Jamaica. In children, there were characteristic presentations in neonates and young infants and in children six months to six years. Neurologic involvement was common but other organ dysfunction was rare. These findings underscore the need to prevent further epidemics and the quest for a vaccine.
ObjectiveIn 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.MethodsHospitalized 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.ResultsThere 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.ConclusionSevere dengue with increased attributable mortality occurred in hospitalized children after Jamaica's maiden Zika epidemic.
Introduction: Jamaica experienced its maiden Zika virus (ZIKV) epidemic in 2016, while dengue (serotypes 3 and 4) and chikungunya were also circulating. Aim: We describe initial trends in microcephaly and arthrogryposis observed by the clinicians from three urban birthing facilities during late 2016 to early 2017. Methods: Reporting of infant microcephaly was required from all birthing facilities in Jamaica. Staff were to be trained in measuring the occipito-frontal head circumference (OFC) using World Health Organization's (WHO) standards. Affected newborns were to be referred for comprehensive paediatric evaluation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
