Another question about the high heat factor in "stopping" the virus. Would it be possible to unwittingly create carriers or immune koi after a summer like we're all having, where pond temps are approaching 90 across the country? This is something that has concerned me over the past few summers... could someone have a short window of temps in the 70s and lose a few fish to "spring startup" and quickly be into the temps where the virus would go dormant without realizing what is going on, or is there too great a mortality rate? Thanks! MJ
