Scientists unveil how Zika virus replicates

The World Health Organization (WHO) declared the Zika virus infection a global threat during the peak of its outbreak in 2016. Since then, scientists and health experts raced to understand the virus better to develop novel and effective vaccines and treatments for the disease. Now, a team of researchers in China revealed how a protein in the virus reshapes its host to boost viral replication.

Research shows how the hepatitis D virus copies itself

A team of researchers has discovered how one crucial step occurs in the lifecycle of the hepatitis D virus (HDV), which causes the widespread and hard to treat liver inflammation called hepatitis D. The study, which was published recently in the Journal of Virology, could help develop antiviral therapy to control this disease.

Connection between herpes virus and Alzheimer’s refuted

A new study has shown that unlike previous claims, there is no association between getting herpes infections and developing Alzheimer’s disease. The study from the researchers at the Baylor College of Medicine was titled, “Are HHV-6A and HHV-7 really more abundant in Alzheimer’s disease?” and was published in the journal Neuron.
