Feline infectious upper respiratory tract disease - an update

DESPITE the widespread availability of 9cat flu9 vaccines, feline upper respiratory tract disease remains a problem, especially in multicat environments. Although rarely fatal, infectious respiratory disease can leave cats with chronic signs. Cats can remain infectious to other cats for much longer than the period of acute infection - in some cases, for life. This, coupled with the inability of the current virus vaccines to protect against infection (as opposed to disease), poses problems for disease control.
