In this study, 1,796 specimens of Aedes caspius were identified from four provinces. Based on the COI and COII sequences obtained for Ae. caspius population, 12 and 11 haplotypes were identified, respectively. The present study evidenced a high degree of intraspecific variation among these populations of Ae. caspius. PMID: 30763508 [PubMed - in process]

by Fadila Amraoui, Wiem Ben Ayed, Yoann Madec, Chafika Faraj, Oumnia Himmi, Ameur Btissam, Mhammed Sarih, Anna-Bella Failloux In 2015, the mosquitoAedes albopictus was detected in Rabat, Morocco. This invasive species can be involved in the transmission of more than 25 arboviruses. It is known that each combination of mosquito population and virus genotype leads to a specific interaction that can shape the outcome of infection. Testing the vector competence of local mosquitoes is therefore a prerequisite to assess the risks of emergence. A field-collected strain ofAe.albopictus from Morocco was experimentally infected wit...

Wang Mosquito-borne diseases constitute a large portion of infectious diseases, causing more than 700,000 deaths annually. Mosquito-transmitted viruses, such as yellow fever, dengue, West Nile, chikungunya, and Zika viruses, have re-emerged recently and remain a public health threat worldwide. Global climate change, rapid urbanization, burgeoning international travel, expansion of mosquito populations, vector competence, and host and viral genetics may all together contribute to the re-emergence of arboviruses. In this brief review, we summarize the host and viral genetic determinants that may enhance infectivity in t...

Abstract The yellow fever mosquito, Aedes aegypti, has facilitated the re-emergence of dengue virus (DENV) and emergence of chikungunya virus (CHIKV) and Zika virus (ZIKV) in the Americas and the Caribbean. The recent transmission of these arboviruses in the continental United States has been limited, to date, to South Florida and South Texas despite Ae. aegypti occurring over a much larger geographical region within the country. The main goal of our study was to provide the first long term longitudinal study of Ae. aegypti and enhance the knowledge about the indoor and outdoor relative abundance of Ae. aegypti as...

Publication date: February 2019Source: Current Opinion in Virology, Volume 34Author(s): Yan-Jang S Huang, Stephen Higgs, Dana L VanlandinghamArthropod-borne viruses (arboviruses) are ecologically distinct from many other pathogens because of the involvement of arthropod vectors and animal reservoirs. Several mosquito-borne arboviruses have emerged in various geographic regions during the past few decades. Since the beginning of the 21st century, the emergence of two mosquito-borne arboviruses, chikungunya and Zika, has taken place globally. Millions of infections have not only changed the epidemiology of previously obscure...

In this study, six CHIKV isolates circulating in midwestern Brazil (Mato Grosso state) were isolated from patient sera, and their complete genomes were sequenced using a high-throughput sequencing platform. All of these isolates shared high nucleotide sequence similarity with CHIKV isolates from northeastern Brazil and were found to belong to the ECSA lineage. These CHIKV isolates did not contain the A226V or L210Q mutations that are associated with increased transmissibility byA. albopictus, suggesting that the CHIKV isolates circulating in midwestern Brazil are predominantly transmitted byA. aegypti.

Weaver, J. Joseph Kim, Laurent Humeau, Pablo Tebas, David B. Weiner, Kar Muthumani Mayaro virus (MAYV) of the genus alphavirus is a mosquito-transmitted emerging infectious disease that causes an acute febrile illness, rash, headaches, and nausea that may turn into incapacitating, persistent arthralgias in some victims. Since its discovery in Trinidad in 1954, cases of MAYV infe ction have largely been confined there and to the north...

The objective of this study was to determine the prevalence of six arboviruses in the Kassala state of east Sudan during unknown fever outbreak. A cross sectional hospital-based study was conducted in the Kassala, Teaching Hospital. Blood samples from 119 patients suffering from unknown fever were used for screening of six arboviruses, hepatitis E virus and malarial using molecular techniques and serology.  The overall arboviruses seroprevelance was 61.3% (73/119). The highest positivity rate was 73.1% (52/73) chikungunya virus; 29 males and 20 females patients were chikungunya positive. Other arboviruses we...

Authors: Freitas ARR, Gérardin P, Kassar L, Donalisio MR Abstract Although traditionally chikungunya virus is considered non-fatal, recent studies suggest that there may be in fact underreporting of deaths in some situations. A major chikungunya epidemic hit Jamaica in 2014 but no chikungunya-associated deaths were reported. We assessed the excess of all-cause deaths during this epidemic. Excess deaths were estimated by difference between observed and expected mortality based on the average age-specific mortality rate of 2012-2013, using the 99% confidence interval. There was an excess of 2,499 deaths during...
