“…The southward expansion of the spatial weighted mean centre tendency observed in our research has been confirmed by recent DF outbreaks registered in Bolivia, the northern provinces of Argentina and in the Buenos Aires metropolitan area (Guzman and Istúriz, 2010). While DF has a pronounced circulation in most Caribbean countries, no viral activity was detected in Cuba from 1982 to 1996 (González et al, 2005), perhaps due to its political and economical isolation.…”

Abstract. El Niño South Oscillation (ENSO) is one climatic phenomenon related to the inter-annual variability of global meteorological patterns influencing sea surface temperature and rainfall variability. It influences human health indirectly through extreme temperature and moisture conditions that may accelerate the spread of some vector-borne viral diseases, like dengue fever (DF). This work examines the spatial distribution of association between ENSO and DF in the countries of the Americas during 1995-2004, which includes the 1997-1998 El Niño, one of the most important climatic events of 20 th century. Data regarding the South Oscillation index (SOI), indicating El Niño-La Niña activity, were obtained from Australian Bureau of Meteorology. The annual DF incidence (AI y ) by country was computed using Pan-American Health Association data. SOI and AI y values were standardised as deviations from the mean and plotted in bars-line graphics. The regression coefficient values between SOI and AI y (r SOI,AI ) were calculated and spatially interpolated by an inverse distance weighted algorithm. The results indicate that among the five years registering high number of cases (1998, 2002, 2001, 2003 and 1997), four had El Niño activity. In the southern hemisphere, the annual spatial weighted mean centre of epidemics moved southward, from 6°31' S in 1995 to 21°12' S in 1999 and the r SOI,AI values were negative in Cuba, Belize, Guyana and Costa Rica, indicating a synchrony between higher DF incidence rates and a higher El Niño activity. The r SOI,AI map allows visualisation of a graded surface with higher values of ENSO-DF associations for Mexico, Central America, northern Caribbean islands and the extreme north-northwest of South America.

“…106(3): 346-352, May 2011 Dengue fever represents one of the major public health concerns, with millions of cases and thousands of deaths every year in urban, suburban and rural tropical areas (Guzman & Istúriz 2010). In the Americas, the disease has an endemoepidemic pattern and includes the circulation of all four serotypes.…”

In French Guiana, pyrethroids and organophosphates have been used for many years against Aedes aegypti. We aimed to establish both the resistance level of Ae. aegypti and the ultra low volume spray efficacy to provide mosquito control services with practical information to implement vector control and resistance management. Resistance to deltamethrin and fenitrothion was observed. In addition, the profound loss of efficacy of AquaK'othrine® and the moderate loss of efficacy of Paluthion® 500 were recorded. Fenitrothion remained the most effective candidate for spatial application in French Guiana until its removal in December 2010. Further investigation of the mechanism of resistance to deltamethrin demonstrated the involvement of mixed-function oxidases and, to a lesser extent, of carboxylesterases. However, these observations alone cannot explain the level of insecticide resistance we observed during tube and cage tests

“…In the past few years, cases of dengue have popped up in Texas, Florida, France, and Croatia. Of the 500,000 cases of severe dengue requiring hospitalization and the roughly 24,000 deaths they cause each year [11], most are in children, according to the WHO [5]. A recent study estimated that there were more people at risk of dengue infection calculating that up to 3.97 billion people are at risk in 128 countries [12] (See Fig 1).…”

Abstract-This paper highlights best practices of technological influenced e-government using ICT, emerging mobile and web 2-0 technology for the effective health Care & disease management system. Modern technology has given a whole new dimension to the concept of good governance, thus embarking a strong and effective influence on citizens and cultural trends. Authors have investigated successful case studies, which are taken from existing practice of egovernment health care projects within Pakistan.Pakistan was hit by the epidemic of dengue, affecting over 350,000 people in 2010. Due to the unprecedented scale of epidemic, the basic health infrastructure was not ready to address the issue. However by 2012 a monitoring mechanism was devised as an e-Govt health care activity, to log all field activities related to prevention/eradication of the disease. The project focused mobile reporting using android phones, EDGE services, and Google maps. 650 smart phones users reported 43,000 activities. The information received was extrapolated to bring all stakeholders of anti-dengue campaign on a single platform and DIMS (Dengue Information Management System) was conceived. Features of DIMS include:A central dashboard to view and dispose of complaints on real-time coming in from the Helpline and Hospitals e-CRS (Electronic Complaint Routing System). 2 Vector Surveillance System for tracking and reporting all indoor / outdoor larvaciding activities. 3 A Disease Reporting System to manage the clinical and lab diagnosis records of dengue affected patients.Utilization of this system has resulted in 0 % deaths reported due to dengue in the past 1.5 years. Careful investigation of step by step usage, reporting to DMIS with Android phone and working behavior of ICT infrastructure are elaborated in this research.
