If you get Swine Flu do you have it for ever?
No, It doesn't. you are usually quarantined for 10-15 days or so
as the body's immine system deals with the virus. The body then
retains a 'memory' of the viral coating of the particulat strain
and will be better able to deal with the virus if returns. You can
now get a vaccine shot if you are in a high risk group.
