Brazil Zika outbreak: ‘May be coming to an end’

Friday, November 17, 2017 -- In 2016, news about the Zika virus in Brazil made the headlines in Europe for the first time. With approximately 65 million people affected, it is one of the largest epidemics in the last few years. The Olympics additionally fuelled fears that the virus could spread globally. When the first cases of newborns with microcephaly, […] The post Brazil Zika outbreak: ‘May be coming to an end’ appeared first on Outbreak News Today.

Drones Distribute Swarms of Sterile Mosquitoes to Stop Zika and Other Diseases

Study Suggests Naturally-Acquired Immunity Against Zika Virus May Already Occur

Friday, November 17, 2017 -- The results of a new study suggest that naturally-acquired immunity against the Zika virus may already occur in women in endemic regions of the world.

Congress Pushes for Predictive Models for Zika and Other Infectious Disease Outbreaks: Public Health Watch

Drug used to prevent and treat malaria may also be effective for Zika virus

Friday, November 17, 2017 -- A new collaborative study led by researchers at Sanford Burnham Prebys Medical Discovery Institute and UC San Diego School of Medicine has found that a medication used to prevent and treat malaria may also be effective for Zika virus.

Cheap, Safe Anti-Malaria Drug Reduces Zika Virus in Mice

A single mutation in the prM protein of Zika virus contributes to fetal microcephaly

Thursday, November 16, 2017 -- Zika virus (ZIKV) has evolved into a global health threat because of its unexpected causal link to microcephaly. Phylogenetic analysis reveals that contemporary epidemic strains have accumulated multiple substitutions from their Asian ancestor. Here we show that a single serine-to-asparagine substitution [Ser139->Asn139 (S139N)] in the viral polyprotein substantially increased ZIKV infectivity in both human and mouse neural progenitor cells (NPCs) and led to more severe microcephaly in the mouse fetus, as well as higher mortality rates in neonatal mice. Evolutionary analysis indicates that the S139N substitution arose before the 2013 outbreak in French Polynesia and has been stably maintained during subsequent spread to the Americas. This functional adaption makes ZIKV more virulent to human NPCs, thus contributing to the
