Overview
Pathophysiology
- Virus attaches to sialic acid receptor though GP protein and is endocytosed by clathrins in the host cell.
- Endosome acidification induces fusion of virus membrane with the vesicle membrane
- Encapsidated RNA segments migrate to the nucleus.
- Transcription of genomic segments by the viral polymerase produces mRNAs that are capped and polyadenylated by the viral polymerase.
- Replication of genomic segments.
- High level of M1 protein induces genomes segments export from nucleus by NEP protein.
- Virus assembly and budding occurs at the plasma membrane.
