The first step will be to quarantine the infected rat from the uninfected rats in the home. There is no set treatment for rats that are infected with sialodacryoadenitis and rat coronavirus infections. Treatment is given through antiviral drugs and maintenance of proper hygiene. If your rat has caused damage to its skin or eyes as a result of the irritation this infection can cause, your veterinarian will need to treat the lesions with topical antibiotics. If dehydration is present as a result of lost appetite, supportive care with fluids and electrolyte supplements can be given.
Rats typically recover over a period of two to three weeks, developing resistance to future attacks by these viruses as their immune system responds and builds natural antibodies to the virus. However, you must treat every rat for severe respiratory infections as soon as it begins to show symptoms of any type of viral infection. The preferred choice of treatment is a combination of enrofloxacin, also known as baytril, and doxycycline. Your veterinarian will prescribe the best antiviral medication depending on the primary virus that is found to be causing the infection.
You will need to isolate the infected rat, or rats, from the rest of the group. If possible, removing them to another location entirely is advised, because of the airborne nature of this virus' transmission. If this is not possible, moving them to another room in the house will have to be enough. Consult with your veterinarian on the best ways to disinfect your rat's living environment and cages, and when you can safely place the rats in the same environment with other rats again.
Because symptoms of this infection are not always readily apparent, one of the most important steps in preventing this infection is isolating new rats for at least two to three weeks before they are included with the established group of rats. As a general precaution, you must always wash your hands and change your clothing after handling any rat -- or other animal -- before handling your own rats again.
