Scientists have discovered a new pathway the dengue virus takes to suppress the human immune system, expressing hope for the development for more effective drugs to tackle the deadly disease.

They said that when a virus enters the body and infects cells, it induces the production and release of interferons, which are proteins that raise the bodies' anti-viral defence mechanisms.

The dengue virus enters the cell and produces large quantities of a non-coding, highly-structured viral RNA termed "sfRNA" part of the genetic material of the dengue virus.
