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.

Famous quotes containing the word host:
“The host is rushing ‘twixt night and day,
And where is there hope or deed as fair?
Caoilte tossing his burning hair,
And Niamh calling Away, come away.”
—William Butler Yeats (1865–1939)
