Diffuse Hyperpigmentation Can Distinguish Chikungunya From Other Arbovirus Infections Diffuse Hyperpigmentation Can Distinguish Chikungunya From Other Arbovirus Infections

With outbreaks of chikungunya fever (CF) having been reported in previously untouched regions from southern Europe to the Americas, clinicians need to be aware of even such relatively rare signs of the infection as acquired diffuse hyperpigmentation, researchers say.Reuters Health Information

martt A Chikungunya virus (CHIKV) outbreak in Italy in 2007 spread to include the islands of the Caribbean and most of the Americas and still circulates in Europe and Africa. Florida being close in distance to the Caribbean islands experienced a CHIKV outbreak in 2014 and continues to have a few travel-related cases each year. It is known that different environmental conditions in different regions can result in genetic variation that favor changes in competence to arbovirus. We evaluated the vector competence of Florida Aedes aegypti for CHIKV and determined if there is a geographic component that influences genes inv...

This study was performed to evaluate the clinical course of the infection in 168 patients with autoimmune inflammatory disease using biological disease-modifying antirheumatic drugs (bDMARDs), comparing this group with 56 household controls. Anti-CHIKV IgG serology was positive in 42 (25%) of the patients in the bDMARD group and in 15 (27%) of the controls (p=0.79). Of those with positive serology, 32 (76%) and 14 (93%) were symptomatic among subjects in the bDMARD and control groups, respectively (p=0.87). Persistence of musculoskeletal symptoms for more than three months occurred in 64% of the patients in the control gro...

by Marisa A. P. Donnelly, Susanne Kluh, Robert E. Snyder, Christopher M. Barker The spread ofAedes aegypti in California and other regions of the U.S. has increased the need to understand the potential for local chains ofAe.aegypti-borne virus transmission, particularly in arid regions of the state where the ecology of these mosquitoes is less understood. For public health and vector control programs, it is helpful to know whether variation in risk of local transmission can be attributed to socio-demographic factors that could help to target surveillance and control programs. Socio-demographic factors have been shown to i...

We report a considerable exposure to RVFV and CHIKV among Wami-Dakawa residents during the dry season and an absence of exposure of the viruses among hum ans in Magugu site. In both sites, no DENV exposure nor infection was detected.

In conclusion, our data provides evidence that CHIKV infection activates the TLR pathways in primary monocytes and MDMs, which play a crucial role in CHIKV pathogenesis and/or host defense, differentially. However, additional studies are required to determine the functional role of TLRs in monocytes and MDMs. PMID: 32634389 [PubMed - as supplied by publisher]

After the outbreak in French Polynesia, Zika virus (ZIKV) explosive pandemic occurred in 2015, reports that ZIKV was linked to other diseases, especially neurological complications such as Guillain-Barré Syndrome (GBS), also burst in almost every continent, thereby turning into an international concern. In South America, the highest incidence occurred in Venezuela with approximately 680 cases of GBS after ZIKV infection. Currently, the main roots of this association remain unknown. In this regard, it is thought that the immune system plays a central role in such association through the host protection or even improv...

gari Alphaviruses are globally distributed and predominately transmitted by mosquitoes. Aedes species are common vectors for the clinically important alphaviruses—Chikungunya, Sindbis, and Ross River (RRV) viruses—with Aedes aegypti also being a vector for the flaviviruses dengue, Yellow Fever, and Zika viruses. Ae. aegypti was putatively implicated in the large 1979–1980 South Pacific Islands outbreak of RRV—the leading cause of arboviral disease in Australia today. The RNA interference (RNAi) defense response in mosquitoes involves a number of small RNAs, with their kinetics in...

Chikungunya virus (CHIKV) is an arthropod-borne virus (arbovirus) of epidemic concern, transmitted by Aedes ssp. mosquitoes, and is the etiologic agent of a febrile and incapacitating arthritogenic illness responsible for millions of human cases worldwide. After major outbreaks starting in 2004, CHIKV spread to subtropical areas and western hemisphere coming from sub-Saharan Africa, South East Asia, and the Indian subcontinent. Even though CHIKV disease is self-limiting and non-lethal, more than 30% of the infected individuals will develop chronic disease with persistent severe joint pain, tenosynovitis, and incapacitating...
