The group of the newly recognized group of viruses, the coronaviruses, include avian virus, the mouse hepatitis virus, and a number of virus strains of man. A naturally occurring virus, it is isolated to the lungs of rats and is rampant in colony of wild rats, resulting in fatal pneumonia in baby rats. Infection of rat coronavirus is serious and self-limiting, but there is no eradication or control of the virus, and rats are immune to reinfection. The rat coronavirus (RCV), shows signs of the coronavirus group: respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
