Sudan reports outbreak of mosquito-borne Chikungunya disease in eastern state

More than 11,000 people in Sudan's eastern state of Kassala have been infected over the past month by Chikungunya, a debilitating mosquito-borne viral disease, but no deaths have been reported, a Sudanese official said on Tuesday.

a GP Abstract Chikungunya virus (CHIKV) is an arbovirus that emerged in the Americas in 2013. Infection with CHIKV is symptomatic in most of the cases and patients can develop chronic arthralgia that lasts from months to years in over 40% of the cases. The East-Central-South Africa (ECSA) genotype was introduced in Brazil in 2014, in Bahia State. Here we report the circulation of the CHIKV ECSA genotype in Piaui State, Northeast Brazil, during the years 2016-2017. The phylogenetic analysis revealed a single introduction of this lineage probably in 2015 and its maintenance at least until 2017. This analysis has als...

Conclusions/significanceOur study shows that exposure to bites ofAe.albopictus orAe.aegypti evokes in mice species-specific IgG responses to al34k2 or ae34k2, respectively. Deeper understanding of duration of antibody response and validation in natural conditions of human exposure toAedes mosquitoes are certainly needed. However, our findings point to the al34k2 salivary protein as a promising potential candidate for the development of immunoassays to evaluate human exposure toAe.albopictus. This would be a step forward in the establishment of a serological toolbox for the simultaneous assessment of human exposure toAedes ...

by Elliott F. Miot, Fabien Aubry, St éphanie Dabo, Ian H. Mendenhall, Sébastien Marcombe, Cheong H. Tan, Lee C. Ng, Anna-Bella Failloux, Julien Pompon, Paul T. 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...

CONCLUSIONS: Rapid transmission and high mortality rate are serious problems, especially in regions with co-circulating arboviruses.

Authors: Kumar R, Rajvanshi P, Khosla H, Arora S Abstract Chikungunya is an arboviral infection caused by Chikungunya virus, an RNA virus from Togaviridae family.1 The disease manifests as fever, rash and characteristically, with arthralgia.1 Chikungunya is strongly believed to have neurotropism but has not been well studied like other neurotropic arboviruses.2 Encephalitis appears to represent the most common clinical manifestation6 and occurs either simultaneously or within few days of onset of systemic symptoms, during the period of viremia. A delay of more than two weeks has been reported with other complicatio...

ver The unprecedented outbreak of Zika virus (ZIKV) infection in the Americas from 2015 to 2017 prompted the publication of a large body of vector competence data in a relatively short period of time. Although differences in vector competence as a result of disparities in mosquito populations and viral strains are to be expected, the limited competence of many populations of the urban mosquito vector, Aedes aegypti, from the Americas (when its susceptibility is viewed relative to other circulating/reemerging mosquito-borne viruses such as dengue (DENV), yellow fever (YFV), and chikungunya viruses (CHIKV)) has proven a ...

[The Conversation Africa] Ethiopia's second largest city, Dire Dawa, is dealing with a chikungunya fever outbreak. Around 20,000 cases of the mosquito-borne viral infection have been reported since the outbreak started in March 2019. This is the second recorded outbreak of the disease in the country; the first was in 2016. Eunice Anyango Owino spoke to The Conversation Africa about the disease and the burden it places on public health.

Hurricane Dorian’s 185 mph winds and punishingly slow pace smashed entire neighborhoods in the Bahamas, killing at least 50 people. But now, Bahamians are facing a different kind of threat. The lack of access to toilets, clean water and medications puts tens of thousands at risk for disease, public health experts warn. Bahamians in the hardest-hit areas are already suffering from cuts and gashes caused by widespread debris and wreckage. But now aid groups are saying survivors are beginning to show signs of gastrointestinal issues from contaminated water. Those with chronic illnesses are struggling without access to t...
