Researchers show how encapsulated viruses hijack biosynthetic pathways in cells

Researchers from the Universities of Melbourne, York, Warwick and Oxford have shed light on how encapsulated viruses like hepatitis B, dengue and SARS-CoV-2 hijack the protein manufacturing and distribution pathways in the cell - they have also identified a potential broad spectrum anti-viral drug target to stop them in their tracks.

Scientists use genomics to track the outbreak of Yellow fever virus in São Paulo

Yellow fever virus is normally confined to the Amazon region, but the virus circulated in the Southeast of Brazil between 2016 and 2018, causing the worst epidemic and epizootic outbreaks there for decades. The Ministry of Health confirmed 2,251 cases of yellow fever in humans and 1,567 cases in monkeys in Brazil between December 2016 and June 2019.
