KHV & koi....

well, I lost several new purchased koi & the ones IN my pond to KHV 6 weeks
ago.
the shipper is replacing the fish,,(thankfully) but it is a PIA.. luckily I
did NOT have a large assortment of ones in my pond already.

(ok do NOT yell at me,, for not quarantine...... new pond,, fish IN the pond
were mostly 10 cent goldfish)(all my goldfish were unaffected)

anyway..... 3 weeks ago I put in 2 'store' koi.. they seem to be doing
happily.
but I read on koivet,, that goldfish can carry KHV........
so am I 'screwed'???? can I expect them to kick off? anyone else have any
problems?luck

(at least I read heat can 'probably' save them)
