Zika, Dengue and Chikungunya Toolkit: Adaptation for Latin America and the Caribbean

International Federation of Red Cross and Red Crescent Societies. 04/18/2017 These tools for Zika, Dengue and Chikungunya Prevention include three toolkits, teaching modules, and a Seasonal Calendar for Vector Control that were developed to initiate a long-term engagement with the communities at risk through awareness and health promotion materials. These materials will help healthcare practitioners and volunteers foster dialogue with communities and ensure that prevention is seen as the primary way of combating vector-borne diseases. (Text)

bel Arthropod-borne viruses (arboviruses) of vertebrates including dengue, zika, chikungunya, Rift Valley fever, and blue tongue viruses cause extensive morbidity and mortality in humans, agricultural animals, and wildlife across the globe. As obligate intercellular pathogens, arboviruses must be well adapted to the cellular and molecular environment of both their arthropod (invertebrate) and vertebrate hosts, which are vastly different due to hundreds of millions of years of separate evolution. Here we discuss the comparative pressures on arbovirus RNA genomes as a result of a dual host life cycle, focusing on pressur...

Authors: Kim YH, Kim TY, Park JS, Park JS, Lee J, Moon J, Chong CK, Junior IN, Ferry FR, Ahn HJ, Bhatt L, Nam HW Abstract A rapid diagnostic test (RDT) kit was developed to detect non-structural protein 1 (NS1) of yellow fever virus (YFV) using monoclonal antibody. NS1 protein was purified from the cultured YFV and used to immunize mice. Monoclonal antibody to NS1 was selected and conjugated with colloidal gold to produce the YFV NS1 RDT kit. The YFV RDTs were evaluated for sensitivity and specificity using positive and negative samples of monkeys from Brazil and negative human blood samples from Korea. Among monoc...

Publication date: Available online 29 May 2019Source: International Journal of Pediatrics and Adolescent MedicineAuthor(s): Tracy Evans-GilbertAbstractChikungunya (CHIKV), Zika (ZIKV), and Dengue viruses (DENV) exhibit similar epidemiological and clinical patterns but have different pathophysiological mechanisms of disease manifestations. Differences occur in the severity of clinical presentations with the highest mortality in the general population attributed to DENV and neurological morbidity due to ZIKV. ZIKV and DENV infections can cause fetal loss with ZIKV exhibiting teratogenesis. CHIKV is associated with severe com...

e;o G Abstract Guillain-Barre syndrome (GBS) is one of the main neurologic manifestations of arboviruses, especially Zika virus infection. As known, the prevalence of these diseases is high, so the risk of having an increase on GBS is relevant. The study purposes making a comparative survey between the involvement of dengue, Zika and chikungunya infections in the development of the GBS in Brazil, as well as search in literature resemblances and distinctions between beforehand reported cases. It was performed an electronic search in online databases, with articles published between the years of 2004 to 2018. A tota...

by Spencer J. Fox, Steven E. Bellan, T. Alex Perkins, Michael A. Johansson, Lauren Ancel Meyers As emerging and re-emerging infectious arboviruses like dengue, chikungunya, and Zika threaten new populations worldwide, officials scramble to assess local severity and transmissibility, with little to no epidemiological history to draw upon. Indirect estimates of risk from vector habitat suitabi lity maps are prone to great uncertainty, while direct estimates from epidemiological data are only possible after cases accumulate and, given environmental constraints on arbovirus transmission, cannot be widely generalized beyond th...

Failloux Although the role of exogenous small interfering RNA (siRNA) and P-element induced wimpy testis (PIWI)-interacting RNA (piRNA) pathways in mosquito antiviral immunity is increasingly better understood, there is still little knowledge regarding the role of mosquito cellular microRNA (miRNA). Identifying direct interactions between the mosquito miRNAs and the RNA genome of arboviruses and choosing the relevant miRNA candidates to explore resulting antiviral mechanisms are critical. Here, we carried out genomic analyses to identify Aedes aegypti miRNAs that potentially interact with various lineages and genotyp...

rio N, ARBOALVO Network Abstract Aedes spp. are considered the main vectors of dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses in the world. Arbovirus detection in Aedes mosquitoes can alert authorities to possible outbreaks, reducing the impact of these diseases. The purpose of this study was to perform an operational strategy for virological surveillance of DENV, ZIKV and CHIKV in adult Aedes aegypti and Aedes albopictus mosquitoes captured at different key-sites in an endemic urban area of the Northeast Region of Brazil, with the prospect of discussing its role as part of an alert system for outbreak...
