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.

“Thrust, my daughter or son, to escape, there is none, none, none,
Nor when all ponderous heaven’s host of waters breaks.”
