FCV is related to upper respiratory tract diseases and can be identified by rhinitis, pneumonia, fever, lameness and oral ulcerations. Most marine mammals (except sea otters) don't chew their food. Such mass mortality events may become increasingly common if climate extremes disrupt historic stable relationships between co-existing pathogens and their susceptible hosts..

Feline Coronavirus is an upper respiratory infection not dissimilar to FHV, which is transmitted by various routes; faecal, oral and possibly aerosolized.
