“…Once again, the Cuban government mobilized a major vector control campaign, and every house in Havana was inspected 10 times. Starting with an HI of 0.49% at the beginning of the epidemic, within three months the house index had been reduced to 0.01% (50). In 2006, another outbreak of DF/DHF was reported from 4 of 14 provinces (105); however, few details about this epidemic are publicly known.…”

“…Both DENV3 III subtypes A and B were present in Sri Lanka in 1989, but only one subtype (B) persisted after 1989 and was involved in all subsequent cases of DHF/DSS on the island. Additionally, DENV3 III subtype B has since spread to the Americas, where it has also been associated with epidemics of DHF/DSS (27, 50,87). Other genotypes of DENV3 may also be associated with increased severity of disease; genotype I viruses reintroduced into islands of the Western Pacific have been associated with DHF/DSS, in contrast to past epidemics of DF associated with genotype IV (80).…”

Dengue is a spectrum of disease caused by four serotypes of the most prevalent arthropod-borne virus affecting humans today, and its incidence has increased dramatically in the past 50 years. Due in part to population growth and uncontrolled urbanization in tropical and subtropical countries, breeding sites for the mosquitoes that transmit dengue virus have proliferated, and successful vector control has proven problematic. Dengue viruses have evolved rapidly as they have spread worldwide, and genotypes associated with increased virulence have expanded from South and Southeast Asia into the Pacific and the Americas. This review explores the human, mosquito, and viral factors that contribute to the global spread and persistence of dengue, as well as the interaction between the three spheres, in the context of ecological and climate changes. What is known, as well as gaps in knowledge, is emphasized in light of future prospects for control and prevention of this pandemic disease.

“…The HI has oscillated between 0.06 and 0.8% throughout 2003–2007. Still, Guantanamo was affected by dengue outbreaks in 1981 [ 15 ], 2001 [ 17 ] and 2006 [ 18 ]. There has been no evidence of the presence of Ae .…”

No Effect of Insecticide Treated Curtain Deployment on Aedes Infestation in a Cluster Randomized Trial in a Setting of Low Dengue Transmission in Guantanamo, Cuba

et al. 2015

Objective & MethodologyThe current study evaluated the effectiveness and cost-effectiveness of Insecticide Treated Curtain (ITC) deployment for reducing dengue vector infestation levels in the Cuban context with intensive routine control activities. A cluster randomized controlled trial took place in Guantanamo city, east Cuba. Twelve neighborhoods (about 500 households each) were selected among the ones with the highest Aedes infestation levels in the previous two years, and were randomly allocated to the intervention and control arms. Long lasting ITC (PermaNet) were distributed in the intervention clusters in March 2009. Routine control activities were continued in the whole study area. In both study arms, we monitored monthly pre- and post-intervention House Index (HI, number of houses with at least 1 container with Aedes immature stages/100 houses inspected), during 12 and 18 months respectively. We evaluated the effect of ITC deployment on HI by fitting a generalized linear regression model with a negative binomial link function to these data.Principal FindingsAt distribution, the ITC coverage (% of households using ≥1 ITC) reached 98.4%, with a median of 3 ITC distributed/household. After 18 months, the coverage remained 97.4%. The local Aedes species was susceptible to deltamethrin (mosquito mortality rate of 99.7%) and the residual deltamethrin activity in the ITC was within acceptable levels (mosquito mortality rate of 73.1%) after one year of curtain use. Over the 18 month observation period after ITC distribution, the adjusted HI rate ratio, intervention versus control clusters, was 1.15 (95% CI 0.57 to 2.34). The annualized cost per household of ITC implementation was 3.8 USD, against 16.8 USD for all routine ACP activities.ConclusionDeployment of ITC in a setting with already intensive routine Aedes control actions does not lead to reductions in Aedes infestation levels.

“…History has shown that vector control measures can be effective in reducing arthropod-borne virus diseases [120, 183–186]. However, many developing countries do not have the necessary resources and infrastructure for successful eradication measures to be implemented and sustainable in the manner that has been achieved in Singapore and Cuba [187].…”

Traditionally, the four dengue virus serotypes have been associated with fever, rash, and the more severe forms, haemorrhagic fever and shock syndrome. As our knowledge as well as understanding of these viruses increases, we now recognise not only that they are causing increasing numbers of human infections but also that they may cause neurological and other clinical complications, with sequelae or fatal consequences. In this review we attempt to highlight some of these features in the context of dengue virus pathogenesis. We also examine some of the efforts currently underway to control this “scourge” of the tropical and subtropical world.
