Spontaneous Rabies in a Stray Bitch after Parturition Induced Immunosuppression —Investigating an Impending Outbreak of Rabies with One Health Approach
Background: Rabies is endemic in India and every half an hour a person dies of this dreaded disease. Stray roaming dogs, mostly unvaccinated, are most dangerous host in spread of rabies in India and in our state of Himachal Pradesh. Timely prophylaxis is the only method to save animal bite victims, including that of rabid dog bite patients.
