Rabies diagnosis





Reporting Rabies (animal and human cases and suspects).
Impression smears prepared from a composite sample of brain tissue are treated with antirabies serum or globulin labelled with fluorescein isothiocyanate (fitc).
After having contact with a rabid animal, the rabies virus may remain alive on your pets skin for up to two hours.
The direct fluorescent antibody test is the most accurate test for diagnosis -but because it requires brain tissue, it can only be performed after the death of the animal.Vaccinating your pet not only protects him from getting rabies, it protects him if he bites someone.Theyre exposed to wild animals and have a greater chance of fighting with infected stray dogs or cats.Alternatively, particularly where fluorescence microscopy is not available, a direct rapid immunohistochemistry test (dRIT) was developed with a similar sensitivity and specificity as the FAT.It can also be transmitted through a scratch or when infected saliva makes contact with mucous membranes or an open, fresh wound.Because rabies exposure to suspect animals is a medical urgency, but not an emergency, testing within this period is more than adequate for determining if a person was exposed to a rabid animal, and requires rabies postexposure vaccinations.Skin biopsy specimens are examined for rabies antigen in the cutaneous nerves at the base of hair follicles.



Dogs who have bitten humans are required to be confined for at least 10 days to see if rabies develops, and if the animals vaccination records are not current, a lengthy quarantine or even euthanasia may be mandated.
For more information see the rabies surveillance blueprint and the OIE Manual of Diagnostic Tests and Vaccines for Terrestrial Animals.
Please do not attempt to capture any wild animals.
The laboratory results may save a patient from unnecessary physical and psychological trauma, and financial burdens, if the animal is not rabid.
Though preventable, there is good reason that the word rabies evokes fear in people.They may eat unusual things and hide in dark places.Physicians and veterinarians may obtain information on rabies, including human exposure, prophylaxis, and bite management by calling.Within a few hours, a diagnostic laboratory can determine whether or not an animal is rabid and inform the responsible medical personnel.Youll also need to contact local animal control officers if the animal who bit your pet is still at large; they will be best able to safely apprehend and remove the animal from the environment.
