What is Chikungunya Virus?

Can you tell me anything about this chikungunya virus that seems to be spreading in the U.S.? I heard it is related to dengue fever. How serious is it?

Ritu Priya, V SujathaIndian Journal of Public Health 2020 64(6):105-107 There is a lot of discussion on COVID-19 control strategies from the mainstream approaches, but it is also necessary to examine the contributions of the Ayurveda, Yoga and Naturopathy, Unani, Siddha, Sowa Riga and Homeopathy (AYUSH) sector, which is now being brought into public health interventions nationally. Although the AYUSH sector had previously joined the management of dengue and chikungunya outbreaks in some Indian states, its participation has remained contentious and there is reluctance in mainstream public health discourses to seriously exa...

Conclusions/SignificanceCHIKV remains an underdiagnosed acute febrile illness in Indonesia. Public health measures should support development of CHIKV diagnostic capacity. Improved access to point-of-care diagnostic tests and clinical training on presentations of ACI will facilitate appropriate case management such as avoiding unneccessary treatments or antibiotics, early response to control mosquito population and eventually reducing disease transmission.

Abstract Aedes (Stegomyia) aegypti is a cosmopolitan species that transmits arbovirus of medical importance as dengue, Zika, and chikungunya. The main strategy employed for the control of this mosquito is the use of larvicidal agents. However, the overuse of synthetic chemical larvicides has led to an increase in resistant insects, making management difficult. Therefore, the use of botanical insecticide-based nanosystems as an alternative to the use of synthetic agents for the control of Ae. aegypti has gained more considerable attention in the last years, mainly due to the advantages of nanostructured delivery sy...

va MM, Gomes CES Abstract The Dengue, Zika and Chikungunya viruses have been spreading in tropical regions, causing epidemics with high morbidity rates and fatal cases. The aim of this study was to assess the diversity and abundance of culicid species and the presence of arboviruses in mosquitoes, at the epicenter of an epidemic outbreak that occurred in people living near an urban Atlantic Forest park. Mosquitoes were captured with a Shannon trap between 2 and 6 pm in seven months of 2019. The Chikungunya virus was investigated according to the protocol described by Lanciotti (2007). The most abundant species wer...

Abstract Aedes aegypti is the vector of important diseases like dengue, zika, chikungunya, and yellow fever. Vector control is pivotal in combating the spread of these mosquito-borne illnesses. Photoactivable larvicide curcumin obtained from Curcuma longa Linnaeus has shown high potential for Ae. aegypti larvae control. However, the toxicity of this photosensitizer (PS) might jeopardize non-target aquatic organisms. The aim of this study was to evaluate the toxicity of this PS to Daphnia magna and Danio rerio, besides assessing its mode of action through larvae biochemical and histological studies. Three PS formul...

(University of Colorado Anschutz Medical Campus) In a new study, researchers from the Colorado School of Public Health at the University of Colorado Anschutz Medical Campus call attention to the emergence of mosquito-borne viral outbreaks in West Africa, such as dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses.

Beuret Identification and characterization of viral genomes in vectors including ticks and mosquitoes positive for pathogens of great public health concern using metagenomic next generation sequencing (mNGS) has challenges. One such challenge is the ability to efficiently recover viral RNA which is typically dependent on sample processing. We evaluated the quantitative effect of six different extraction methods in recovering viral RNA in vectors using negative tick homogenates spiked with serial dilutions of tick-borne encephalitis virus (TBEV) and surrogate Langat virus (LGTV). Evaluation was performed using qPCR and...

by Doug E. Brackney, Maria A. Correa, Duncan W. Cozens Macroautophagy is an evolutionarily conserved cellular process critical for maintaining cellular homeostasis. It can additionally function as an innate immune response to viral infection as has been demonstrated for a number of arthropod-borne (arbo-) viruses. Arboviruses are maintained in a trans mission cycle between vertebrate hosts and invertebrate vectors yet the majority of studies assessing autophagy-arbovirus interactions have been limited to the mammalian host. Therefore we evaluated the role of autophagy during arbovirus infection of the invertebrate vector ...

Conclusions/SignificanceThis study showed the ubiquitous distribution and abundance ofAe.polynesiensis on the three islands and demonstrated that local populations were able to transmit CHIKV. Combined with the presence and expansion ofAe.aegypti on the main island of Wallis, these data highlight the risk of transmission of arboviral diseases in the territory of Wallis and Futuna and provide relevant information for entomological surveillance and vector control programs.
