Viruses,especially the common viruses such as SARS-CoV-2,influenza A virus,human immunodefi-ciency virus,dengue virus and hepatitis B virus,seriously affect human life and health.Meanwhile,many new outbreaks of viral infectious diseases continue to pose a potential threat to human society as the space for human activities continues to expand.This paper provides a systematic review of the progress of research on processes of viral invasion and invasion pathways into cells,which provides important references for the future research on the mechanisms of viral invasion,broad-spectrum antiviral drugs targeting the invasion pathways into cells and novel viral vectors.
