Viewpoint: filovirus haemorrhagic fever outbreaks: much ado about nothing?

The recent outbreak of Marburg haemorrhagic fever in the Democratic Republic of Congo has put the filovirus threat back on the international health agenda. This paper gives an overview of Marburg and Ebola outbreaks so far observed and puts them in a public health perspective. Damage on the local level has been devastating at times, but was marginal on the international level despite the considerable media attention these outbreaks received. The potential hazard of outbreaks, however, after export of filovirus from its natural environment into metropolitan areas, is argued to be considerable. Some avenues for future research and intervention are explored. Beyond the obvious need to find the reservoir and study the natural history, public health strategies for a more timely and efficient response are urgently needed

Evaluation of the Effectiveness of Insecticide Treated Materials for Household Level Dengue Vector Control

An estimated 40% of the world's population lives at risk of contracting dengue, and it inflicts a significant health, economic and social burden on the populations of endemic areas. In the absence of a vaccine, vector control is the only available strategy to prevent transmission. Some control methods against Aedes aegypti (the main dengue vector) have been successful in reducing vector infestation levels, but rarely sustained the reductions for a prolonged period. We report here on the first effectiveness trial of insecticide treated curtains and jar covers against A. aegypti implemented under ‘real-life’ conditions. The coverage of tools was high at distribution, but declined quickly over the 18 months of follow up. The vector infestation levels showed a sustained 55% decrease in the intervention clusters, while no discernable pattern was observed at the municipal level. At least 50% curtain coverage was needed to reduce A. aegypti infestation levels by 50%. We concluded that deployment of insecticide treated window curtains in households can result in significant reductions in dengue vector levels, which are related to dengue transmission risk. The magnitude of the effect depends on the curtain coverage attained, which itself can decline rapidly over time

Community involvement in dengue vector control: cluster randomised trial

Objective To assess the effectiveness of an integrated community based environmental management strategy to control Aedes aegypti, the vector of dengue, compared with a routine strategy

Current evidence on the proposals of local intervention for diagnosis and management of social determinants of health of the Cuban population

De Vos, Pol - ORCID 0000-0002-1672-6469 https://orcid.org/0000-0002-1672-6469Los determinantes sociales de la salud son las condiciones sociales en las cuales las personas que conforman una población determinada nacen, viven y trabajan. El presente artículo tiene el objetivo de documentar las evidencias actuales sobre las propuestas de intervención local para el estudio y manejo de los determinantes sociales de la salud de la población cubana. Desde una perspectiva estructural las variables de servicios de salud muestran diferencias entre territorios, asociadas básicamente a la existencia de un sistema de salud único con cobertura y acceso universal para toda la población. Se observan mayores diferenciales en el comportamiento de los llamados “determinantes no médicos”, como densidad poblacional, producción y circulación económica, mostrando estas diferencias un patrón geográfico. También se observan diferenciales en el comportamiento de la mortalidad materna y la hipertensión arterial entre territorios y en el tiempo. La productividad económica y las condiciones de vida están poco relacionadas con otros indicadores de resultados. Ante lo anteriormente expuesto se presenta una propuesta metodológica para el estudio y manejo de los determinantes sociales de la salud. Se requieren espacios de estudio de los determinantes sociales a nivel local, mediante técnicas multivariadas cuyos resultados aporten insumos para el diseño de intervenciones integrales basadas en los enfoques de planificación estratégica, acción intersectorial y participación social. Se impone insertar en la práctica del sistema de salud cubano un enfoque dirigido a trabajar más con los determinantes sociales de la salud, para lo cual se propone un modelo para el estudio e intervención local.Social determinants of health are the social conditions where members of a particular population are born, live and work. This article was aimed at documenting the current evidence on the proposed local intervention for the study and management of social determinants of health of the Cuban population. From a structural perspective, the health service variables show differences among the regions, mainly associated to the existence of a single health system with universal coverage and access for the entire population. Greatest differences are observed in the behavior of "non-medical determinants" such as population density, economic production and circulation, these differences showing a geographical pattern. Differentials are also observed in the behavior of maternal mortality and hypertension among regions and in the course of time. Economic productivity and living conditions are poorly related to other result indicators. Given the above-mentioned, a methodological proposal for the study and management of social determinants of health was presented. Some study spaces of local social determinants are required at local level through multivariate techniques whose results provide inputs for the design of integrated interventions, based on strategic planning approaches, intersectoral action and social involvement. Therefore, an approach to work more with the social determinants of health is required to be integrated into the Cuban health system. A model for local study and intervention were suggested in this paper in order to attain this goal.http://ref.scielo.org/43qnw352pubpub

Indian community health insurance schemes provide partial protection against catastrophic health expenditure

BACKGROUND: More than 72% of health expenditure in India is financed by individual households at the time of illness through out-of-pocket payments. This is a highly regressive way of financing health care and sometimes leads to impoverishment. Health insurance is recommended as a measure to protect households from such catastrophic health expenditure (CHE). We studied two Indian community health insurance (CHI) schemes, ACCORD and SEWA, to determine whether insured households are protected from CHE. METHODS: ACCORD provides health insurance cover for the indigenous population, living in Gudalur, Tamil Nadu. SEWA provides insurance cover for self employed women in the state of Gujarat. Both cover hospitalisation expenses, but only upto a maximum limit of US$23 and US$45, respectively. We reviewed the insurance claims registers in both schemes and identified patients who were hospitalised during the period 01/04/2003 to 31/03/2004. Details of their diagnoses, places and costs of treatment and self-reported annual incomes were obtained. There is no single definition of CHE and none of these have been validated. For this research, we used the following definition; "annual hospital expenditure greater than 10% of annual income," to identify those who experienced CHE. RESULTS: There were a total of 683 and 3152 hospital admissions at ACCORD and SEWA, respectively. In the absence of the CHI scheme, all of the patients at ACCORD and SEWA would have had to pay OOP for their hospitalisation. With the CHI scheme, 67% and 34% of patients did not have to make any out-of-pocket (OOP) payment for their hospital expenses at ACCORD and SEWA, respectively. Both CHI schemes halved the number of households that would have experienced CHE by covering hospital costs. However, despite this, 4% and 23% of households with admissions still experienced CHE at ACCORD and SEWA, respectively. This was related to the following conditions: low annual income, benefit packages with low maximum limits, exclusion of some conditions from the benefit package, and use of the private sector for admissions. CONCLUSION: CHI appears to be effective at halving the incidence of CHE among hospitalised patients. This protection could be further enhanced by improving the design of the CHI schemes, especially by increasing the upper limits of benefit packages, minimising exclusions and controlling costs
