Research has shown that there are two main patterns that
occur with FECV infection.
Most cats will become infected and recover, but will not be immune.
They are susceptible to reinfection the next time they contact the virus. A small number of cats become infected but do not recover.
They become persistent shedders of FECV in the cattery and are the source of reinfection for the other cats.
Therefore, the key to eliminating FECV (and thus the risk of FIP)
in a cattery would be the identification and removal of chronic shedders.
Currently, however, there is no easy way to determine which cats in a cattery are persistent shedders.
The traditional antibody titre for FECV cannot be used to determine which cats are chronic shedders.
The most effective and practical tool is PCR analysis of feces for the presence of FECV,
a test which is not yet widely available.
恐らくこの１文の事をおっしゃっているのかと思いますが、
FIPVを排出する、ではなく「FECV」を排出する猫の識別及び環境からの排除
を推奨しています。カッコ内は（つまりFIPへの危険性を排除する）
という意味で書かれています。
共通して述べられているのはあくまでもFECVsheddersの排除です。
ただ、どの猫がFECVsheddersであるかどうかを調べるのは困難なようですね。
FIPVに発展したFECVに関し猫同士の感染が認められるという記述はどこにもありません。
