Differential response to plant- and human-derived odorants in field surveillance of the dengue vector, Aedes aegypti.

Differential response to plant- and human-derived odorants in field surveillance of the dengue vector, Aedes aegypti. Acta Trop. 2019 Sep 05;:105163 Authors: Omondi WP, Owino EA, Odongo D, Mwangangi JM, Torto B, Tchouassi DP Abstract Linalool oxide (LO) and hexanoic acid (HA) represent plant- and human-derived odorants, respectively, previously found as attractants for the dengue vector Aedes aegypti. Here, we investigated if a blend of both compounds can improve captures of this mosquito species in field trials in two dengue endemic sites, Kilifi and Busia Counties in Kenya. Ae. aegypti captures were significantly higher in Kilifi than Busia (χ21,142=170.63, P

CONCLUSION: The study showed that acute febrile thrombocytopenia is an important seasonal syndrome. The common causes are dengue fever and malaria. Early identification of these diseases and prompt treatment decreases complications and reduces mortality. PMID: 31593535 [PubMed - as supplied by publisher]

Publication date: Available online 20 August 2019Source: Anaesthesia &Intensive Care MedicineAuthor(s): Victoria Howell, Tom BashfordAbstractThe range of infectious diseases encountered while working overseas in resource limited settings varies enormously depending on where in the world one is working, although the majority of low and middle income countries lie within the tropics. Human immunodeficiency virus (HIV), tuberculosis (TB) and malaria are commonly encountered when working in tropical countries and may have an impact upon anaesthesia, either as a direct result of the condition or due to interaction with the ...

o RCP Abstract Several arboviruses have emerged and/or re-emerged in North, Central and South-American countries. Viruses from some regions of Africa and Asia, such as the Zika and Chikungunya virus have been introduced in new continents causing major public health problems. The aim of this study was to investigate the presence of RNA from Zika, Dengue and Chikungunya viruses in symptomatic patients from Rondonia, where the epidemiological profile is still little known, by one-step real-time RT-PCR. The main clinical signs and symtoms were fever (51.2%), headache (78%), chills (6.1%), pruritus (12.2%), exanthema (...

Discussion Dengue is an important arboviral infection that affects about 40% of the world population. It is found mainly in topical and subtropical areas of the world mainly in developing countries but it range is spreading including the United States. A review of common arboviruses can be found here. It is a flaviavirus with 4 distinct serotypes named DENV-1 through DENV-4 and is spread by A. aegypti a day biting mosquito. Infection with one serotype confers immunity to that serotype but not the others. It does offer some protection for cross-infection but this only lasts a few months. Incubation period is 3-14 days with ...

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...

The Oropouche virus (OROV) is an arbovirus member of the Peribunyaviridae family and the Orthobunyavirus genus (Briese et al., 2016), responsible for a febrile syndrome that has affected people since its first discovery in 1955 in Trinidad and Tobago (Anderson et al., 1961). The etiological diagnosis of OROV infection is challenging due to the clinical similarities with other arboviral diseases including dengue, chikungunya, zika, and mayaro viruses, in addition to other pathogens such as Malaria (da Costa et al., 2017; Alvarez-Falconi and R íos, 2010; Travassos da Rosa et al., 2017), and the lack of molecular diffe...

Abstract Of the 3,500 species of mosquitoes worldwide, only a small portion carry and transmit the mosquito-borne diseases (MBDs) that cause approximately half a million deaths annually worldwide. The most common exotic MBDs, such as malaria and dengue, are not currently established in Canada, in part because of our relatively harsh climate; however, this situation could evolve with climate change. Mosquitoes native to Canada may become infected with new pathogens and move into new regions within Canada. In addition, new mosquito species may move into Canada from other countries, and these exotic species may bring...

Abstract Global climate change, driven by anthropogenic greenhouse gas emissions, is being particularly felt in Canada, with warming generally greater than in the rest of the world. Continued warming will be accompanied by changes in precipitation, which will vary across the country and seasons, and by increasing climate variability and extreme weather events. Climate change will likely drive the emergence of infectious diseases in Canada by northward spread from the United States and introduction from elsewhere in the world via air and sea transport. Diseases endemic to Canada are also likely to re-emerge. This s...

Abstract Mosquitoes (Diptera: Culicidae) are the most significant arthropods of medical importance because of the burden of diseases, such as malaria, encephalitis and filariasis, which are caused by pathogens and parasites they transmit to humans. In 2007, the most recently published checklist of Iranian mosquitoes included 64 species representing seven genera. Public databases were searched to the end of August 2018 for publications concerning the diseases in Iran caused by mosquito-borne pathogens. Pertinent information was extracted and analyzed, and the checklist of Iranian mosquitoes was updated. Six arbovir...

In this study, we were able to demonstrate that our measure for mosquito-borne viral suitability is informative in the context of Myanmar, despite the lack of ento-epidemiological datasets with high spatio-temporal resolution. By estimating suitability through climate variables and known ento-epidemiological parameters, we were able to project mosquito-born virus (MBV) suitability at the district level, a resolution for which epidemiological data and mosquito abundance measures are not generally available. Here, we discuss the national and subnational public health and control implications for MBVs in the context of our pr...
