Dengue, chikungunya and Zika virus surveillance in blood donors in Brazil, 2019–2021

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Arbovirus infections are a major public health concern in Brazil and an ongoing blood safety concern. Periodic outbreaks of such infections are common in the general population. This study aimed to establish the rates of dengue, chikungunya and Zika virus (DENV, CHIKV, ZIKV) RNAemia among blood donors at six public ...

Mapping of Aedes albopictus abundance at a local scale in Italy [PDF]

, 2017
Given the growing risk of arbovirus outbreaks in Europe, there is a clear need to better describe the distribution of invasive mosquito species such as Aedes albopictus. Current challenges consist in simulating Ae. albopictus abundance, rather than its

Silvestrol Inhibits Chikungunya Virus Replication [PDF]

Viruses, 2018
Silvestrol, a natural compound that is isolated from plants of the genus Aglaia, is a specific inhibitor of the RNA helicase eIF4A, which unwinds RNA secondary structures in 5′-untranslated regions (UTRs) of mRNAs and allows translation. Silvestrol has a broad antiviral activity against multiple RNA virus families.
