host. While the mechanism of this is yet to be fully understood‚ it is believed that the virus enters the host either through endocytosis or with direct fusion of particles with the plasma membrane (Zerboni et. al‚ 2014). It is predicted that viral envelope proteins interact with cell surface receptor such as manose-6-phosphate. After entry into the host cell the viron undergoes uncoating and protein 62 is produced. This protein is regarded as a transcription factor‚ therefore it must be produced and
