D. Frentiu Dengue, chikungunya and Zika viruses share similar disease features, rendering them difficult to distinguish clinically. Incapacitating arthralgia/arthritis is a specific manifestation associated with chikungunya virus infection. However, the profile of arthralgia/arthritis in Zika virus (ZIKV) cases has not been well characterized. Articles were extracted from PubMed and Scopus databases reporting original data from patients with arthralgia/arthritis, according to the Cochrane Collaboration. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 137 articles reporting ZIKV...

ConclusionOur findings suggest that children exposed and/or infected with CHIKV outside of the intrapartum period experience no significant neurodevelopmental delay at two years of age, as measured by the INTER-NDA, compared to their unexposed and/or uninfected peers. These results complement those of previous studies which showed a neurodevelopmental risk only for children infected during the intrapartum period, while the mother was highly viremic. These results might be reassuring for women of childbearing age and public health officials in CHIKV-endemic regions.

Abstract We estimated the weighted mean basic reproduction number (R0) of chikungunya virus based on outbreak size. R0 was 3.4 (95% CI 2.4-4.2) and varied for 2 primary chikungunya mosquito vectors: 4.1 (95% CI 1.5-6.6) for Aedes aegypti and 2.8 (95% CI 1.8-3.8) for Ae. albopictus.

Background: The dengue virus (DENV) has been in circulation in Brazil for decades, resulting in the occurrence of several outbreaks. The emergence of Chikungunya virus (CHIKV) in 2014 and Zika virus (ZIKV) in 2015 has raised new concerns raised about the prevalence of these arboviruses. Concurrent outbreaks of DENV, CHIKV and ZIKV have taken place in Brazil since 2015, notably in major cities throughout the country's northeastern region. While the state of Bahia has been heavily affected by CHIKV and ZIKV outbreaks, the true burden of these infections remains hidden due to the predominance of asymptomatic infection.

Abstract Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus that has spread to more than 60 countries worldwide. CHIKV infection leads to a febrile illness known as Chikungunya fever (CHIKF), which is characterized by long-lasting and debilitating joint and muscle pain. CHIKV can cause large-scale epidemics with high attack rates, which substantiates the need for development of effective therapeutics suitable for outbreak containment. In this review, we highlight the different strategies used for developing CHIKV small-molecule inhibitors, ranging from high-throughput cell-based screening, in silico sc...
