Disease Surveillance Using Online News: Dengue and Zika in Tropical Countries

ConclusionsThe paper describes a strategy that applies newspaper as proxies to monitor outbreaks of infectious diseases and to study the epidemiology. It has potential applicability in some developing countries and regions with relatively poor medical infrastructures and records. Clearly, large national newspapers in India provide a better source of information on diseases than international outlets. This approach has potential with selected diseases in a few selected countries. Article numbers internationally appear to vary in proportion to the perceived health impact.Graphical abstract

Abstract Sporadic human Zika virus (ZIKV) infections have been recorded in Africa and Asia since the 1950s. Major epidemics occurred only after ZIKV emerged in the Pacific islands and spread to the Americas. Specific biological determinants of the explosive epidemic nature of ZIKV have not been identified. Phylogenetic studies revealed incongruence in ZIKV placement in relation to Aedes-borne dengue viruses (DENV) and Culex-borne flaviviruses. We hypothesized that this incongruence reflects interspecies recombination resulting in ZIKV evasion of cross-protective T-cell immunity. We investigated ZIKV phylogenetic i...

Brey, Louis Lambrechts The case-fatality rate of yellow fever virus (YFV) is one of the highest among arthropod-borne viruses (arboviruses). Although historically, the Asia-Pacific region has remained free of YFV, the risk of introduction has never been higher due to the increasing influx of people from endemic regions and the recent outbreaks in Africa and South America. Singapore is a global hub for trade and tourism and therefore at high risk for Y...

lmair Flaviviruses are the most medically relevant group of arboviruses causing a wide range of diseases in humans and are associated with high mortality and morbidity, as such posing a major health concern. Viruses belonging to this family can be endemic (e.g., dengue virus), but can also cause fulminant outbreaks (e.g., West Nile virus, Japanese encephalitis virus and Zika virus). Intense research efforts in the past decades uncovered shared fundamental strategies used by flaviviruses to successfully replicate in their respective hosts. However, the distinct features contributing to the specific host and tissue tropi...

In recent years, public health threats due to Zika virus (ZIKV) and Ebola virus have increased awareness among the ophthalmic community regarding the visual effect of ocular sequelae identified in association with these emerging infectious diseases. Yellow fever virus (YFV), deemed the “original viral hemorrhagic fever,” resides in the Flavivirus family, which includes other mosquito-borne illnesses, including Dengue (DENV), West Nile (WNV), and ZIKV. Forty-seven countries in Africa (34 [72.3%]) and Central and South America (13 [27.7%]) are endemic for, or have regions endemi c for, YFV, underscoring its globa...

MarquesAbstractDengue (DENV) and Zika (ZIKV) viruses are antigenically and evolutionarily related; immunological cross-reactions between them have been associated to both cross-protection and infection-enhanced mechanisms. Here, DENV-1-4 and ZIKV were investigated through Bayesian coalescent-based approaches and selection-driven Darwinian evolution methods using robust datasets. Our findings show that both DENV and ZIKV,...

Climate change is the greatest health challenge of the 21st century, and threatens all aspects of society, says the WHO in its COP24 Special Report. What could digital health technologies do to support the fight against the climate crisis? How could healthcare processes, facilities, medical devices become more sustainable? As it is humanity’s priority to mitigate the worsening as well as the impact of rising temperatures and extreme weather events, we tried to figure out what role digital health could assume here. We found many options – and even more possibilities for future development. The climate crisis...

Publication date: May 2019Source: Advances in Chronic Kidney Disease, Volume 26, Issue 3Author(s): Emmanuel A. BurdmannThe genus Flavivirus comprises approximately 73 viruses, which share several common aspects, such as dimension, structure, nucleic acid properties, and shape in electronic microscopy. Global incidence of flavivirus infection increased dramatically over the last decades, causing large outbreaks in several areas of the world. These viruses are expanding from endemic tropical and subtropical areas to previously nonendemic areas, affecting and causing diseases in millions of individuals worldwide and posing a ...

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...

Halsey, Uriel Kitron, Amy C. Morrison, Thomas W. Scott During the last 50 years, the geographic range of the mosquitoAedes aegypti has increased dramatically, in parallel with a sharp increase in the disease burden from the viruses it transmits, including Zika, chikungunya, and dengue. There is a growing consensus that vector control is essential to preventAedes-borne diseases, even as effective vaccines become available. What remains uncl...
