Because EHDV is a double-stranded RNA virus, it needs to overcome a specific set of problems, the main one being the fact that double-stranded RNA are unable to be used as template strand during mRNA translation using host cell machinery.
It needs to overcome a specific set of problems. EHDV is a double-stranded RNA virus. Problems are the main one. This main one is being the fact that double. Stranded RNA are unable to be used as template. This template is strand during mRNA translation. This template was using host cell machinery.
