What is Viral entry?
{{wikify|date=March 2022}} '''Viral entry''' is when a [[virus]] goes into the [[cell]] that it has [[Infection|infected]]. It is the first part of the virus’s life. <ref>{{Cite web|title=Virus entry into host cell ~ ViralZone|url=https://viralzone.expasy.org/936|access-date=2022-03-29|website=viralzone.expasy.org}}</ref> Most viruses share some basics steps. First, the virus has to stick or attach to the outside of the cell. Then some [[Protein|proteins]] react to each other. After that, there are a few different ways that viral entry can happen. The first way is called '''membrane fusion'''. The outside layer of the cell has a hole poked in it for the virus to go in. The second way is called '''endocytosis'''. The cell thinks the virus is [[food]] and eats it. The third way is '''Viral penetration.''' This is where the virus [[Injection|injects]] itself into the cell. == References == {{reflist}} [[Category:Viruses]]
