Changes

Cats previously exposed to coronavirus (and therefore with circulating antibody) may be at greater risk as they are more susceptible to taking up virus into mononuclear cells.

Cats previously exposed to coronavirus (and therefore with circulating antibody) may be at greater risk as they are more susceptible to taking up virus into mononuclear cells.

Cats making a biased [[Adaptive Immune System - WikiBlood #Cellular response: Proliferation and Differentiation|Th-1]] response are more likely to evade infection, whereas cats making a balanced response are at moderate risk and cats making a biased [[Adaptive Immune System - WikiBlood #Cellular response: Proliferation and Differentiation| Th-2]] response are at greater risk, as the virus is best tackled by cell mediation and not antibody.
