Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. Like other viruses, the dengue virus is a microscopic structure that can only replicate ...

Researchers found that Zika virus induces cells to create connections, called tunneling nanotubes, that may enable the virus to replicate and spread from mother to fetus. UNIVERSITY PARK, Pa. — In ...

Human norovirus, a positive-strand RNA virus that is the leading cause of viral gastroenteritis accounting for an estimated 685 million cases and approximately 212,000 deaths globally per year, has no ...

A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells ...

It starts quietly, a bite or a scratch, and by the time symptoms surface, it’s often too late. Rabies isn’t just a distant threat—it’s alive and present here in Alabama. Prevention remains critical, ...

Viral outbreaks need a first line of antiviral strategies to tackle emerging viruses since the on-demand development of vaccines or antibody treatment is not always feasible. To address this problem, ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have emerged more times than previously thought. Corroborating the virus-first ...

Prevention remains critical; but once symptoms appear, treatment options are extremely limited. Because rabies hides behind a complex molecular shield, it is nearly impossible to fight. “For more than ...
