“…Independientemente de la categoría del municipio, la gran mayoría experimentó un crecimiento de la población, y se vio afectada por la migración del campo a la ciudad y por la urbanización no planificada, a lo cual hay que añadir la insuficiente infraestructura urbana básica, las viviendas con condiciones deficientes, y la falta de un adecuado suministro de servicios como agua, alcantarillado y recolección de basuras (29,30). Por otra parte, la proliferación masiva de productos no reciclables, como plásticos no retornables, envases y neumáticos, condujo a un deterioro del medio ambiente que favoreció el aumento de los criaderos de mosquitos (31).…”

Comportamiento de la mortalidad por dengue en Colombia entre 1985 y 2012Pablo Chaparro-Narváez, Willian León-Quevedo, Carlos Andrés Castañeda-Orjuela Introduction: Dengue in Colombia is an important public health problem due to the huge economic and social costs it has caused, especially during the disease outbreaks. Objective: To describe the behavior of dengue mortality in Colombia between 1985 and 2012. Materials and methods:We conducted a descriptive study. Information was obtained from mortality and population projection databases provided by the Departamento Administrativo Nacional de Estadística (DANE) for the 1985-2012 period. Mortality rates, rate ratios, and case fatality rates were estimated. Results: A total of 1,990 dengue deaths were registered during this period in Colombia. Dengue mortality rates presented an increasing trend with statistical significance between 1985 and 1998. Higher mortality rates were reported in men both younger than 5 years and older than 65 years. Between 1995 and 2012, category 1 to 4 municipalities reported the highest mortality rates. Case fatality rates varied during the period between 0.01% and 0.39%. Conclusion:Dengue is an avoidable disease that should disappear from mortality statistics as a cause of death. The event is avoidable if the proposed activities from the Estrategia de Gestión Integrada (EGI)-Dengue are implemented and evaluated. We recommend encouraging the development of an informational culture to contribute to decision making and prioritizing resource allocation.

“…The primary infection caused by a single DENV serotype is usually mild and self-limiting. The more severe form of dengue infection is dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) responsible for high morbidity and mortality [2]. Since the introduction of new dengue guidelines by World Health Organization (WHO) in 2009, dengue is classified into three clinical stages: dengue without warning signs; dengue with warning signs (abdominal pain, persistent vomiting, fluid accumulation, mucosal bleeding, lethargy, liver enlargement, increasing hematocrit with decreasing platelets) and severe dengue (dengue with severe plasma leakage, severe bleeding or organ failure) [3].…”

BackgroundDengue virus is the causative agent of dengue fever, a vector borne infection which causes self-limiting to life threatening disease in humans. A sero-epidemiological study was conducted to understand the current epidemiology of dengue virus in Pakistan which is now known as a dengue endemic country after its first reported outbreak in 1994.MethodsTo investigate the prevalence of dengue virus in Pakistan during 2009-2014, a total of 9,493 blood samples were screened for the detection of anti-dengue IgM antibodies using ELISA. Clinical and demographic features available with hospital records were reviewed to ascertain mortalities related to dengue hemorrhagic shock syndrome.ResultsOut of 9,493 samples tested, 37% (3,504) were found positive for anti-dengue IgM antibodies. Of the seropositive cases, 73.6% (2,578/3,504) were male and 26.4% (926/3,504) were female. The highest number (382/929; 41.1%) of sero-positive cases was observed among the individuals of age group 31-40 years. The highest number of symptomatic cases was reported in October (46%; 4,400/9,493), and the highest number of sero-positive cases among symptomatic cases was observed in November (45.7%; 806/1,764). Mean annual patient incidence (MAPI) during 2009-2014 in Pakistan remained 0.30 with the highest annual patient incidence (11.03) found in Islamabad. According to the available medical case record, 472 dengue related deaths were reported during 2009-2014.ConclusionThe data from earlier reports in Pakistan described the dengue virus incidence from limited areas of the country. Our findings are important considering the testing of clinical samples at a larger scale covering patients of vast geographical regions and warrants timely implementation of dengue vector surveillance and control programs.Trial registration numberIt is an epidemiological research study, so trial registration is not required.Electronic supplementary materialThe online version of this article (doi:10.1186/s40249-017-0258-6) contains supplementary material, which is available to authorized users.

“…Simple interventions could help; in our study, people living in houses with uncovered water tanks were 7·9 times more likely to get dengue fever. Those in houses discharging sewage directly into ponds had a 5·9 times higher risk than those in houses 13 with sanitary sewage systems. In the present study, flower vases were noted in 26% of the observed household where as a study by Kamath R et al found flower pots filled with water in 9 or around houses (15%).…”

Introduction Currently dengue is a worldwide public health problem. Almost half of world's populations are at risk of dengue. The first case was reported from Nepal in 2004, since then major outbreaks occurred in the year 2006, 2010, 2012 and 2013. As Jhapa district had outbreak in 2012 and 2013, there is a high chance of outbreak in Morang district also. There might be presence of many known risk factor for dengue transmission at Haraincha Village Development Committee (VDC).Objective To assess the known risk factor associated with dengue transmission in Haraincha Village Development Committee of Morang district of Eastern Nepal.Methodology Community based cross-sectional study was conducted from th th 15 October 2013 to 30 November 2013 in Haraincha VDC of Morang district. The data was collected from 122 households by means of interview using a semi structured questionnaires and direct observation after taking informed consent. We observed the known risk factor of possible dengue transmission. Data were entered into Microsoft excel and analyzed by using SPSS.Results The mean age of the respondent was 38 years with male predominance (61.5%). Only 7.4% were illiterate. The major occupation was agriculture (45.9%). Fifty four percent were above the poverty line. Two percent had history of dengue contracted outside the country. Common risk factors observed were poor drainage system (79%), poor natural light (75%), paddy field nearby household (51%), water filled open containers (44%), big plant near household (31%) and flower vases (26%) etc.Conclusion The known risk factors for dengue transmission were present in Haraincha Village Development Committee.Birat Journal of Health Sciences 2016 1(1): 3-7
