Exposure of Host
Usually viral infection occurs when a virus enters the host, either:
- through a physical breach (a cut in the skin)
- direct inoculation (e.g.mosquito bite)
- direct infection of the surface itself (inhalation of the virus into trachea)
It is usually only after a virus enters a host that it can gain access to possible susceptible cells.
