What is Zoonotic Rabies?
Zoonotic rabies is a viral infection transmitted from infected animals to humans, affecting the central nervous system. It is almost always fatal once symptoms appear but can be prevented with timely medical intervention.
What Causes Zoonotic Rabies?
- Bites or Scratches from Infected Animals – Most commonly from dogs, bats, raccoons, foxes, and other wild mammals carrying the rabies virus.
- Contact with Saliva or Nervous Tissue – Through open wounds or mucous membranes.
What Are the Symptoms of Zoonotic Rabies?
Symptoms usually develop 1 to 3 months after exposure and include:
- Fever and headache
- Weakness or discomfort
- Anxiety, confusion, agitation
- Difficulty swallowing and hydrophobia (fear of water)
- Excessive salivation
- Paralysis and seizures
- Coma leading to death
How is Zoonotic Rabies Diagnosed?
- Medical History – Exposure to potentially rabid animals.
- Laboratory Tests – Detection of rabies virus RNA or antibodies in saliva, blood, cerebrospinal fluid, or skin biopsies.
- Diagnosis is often clinical due to rapid progression.
How is Zoonotic Rabies Treated?
- Post-Exposure Prophylaxis (PEP) – Immediate wound cleansing followed by a series of rabies vaccinations and, if needed, rabies immunoglobulin to prevent onset of disease.
- Supportive Care – Once symptoms appear, treatment is mainly supportive as no cure exists.
Prognosis of Zoonotic Rabies
Rabies is nearly always fatal after symptoms begin. Early post-exposure prophylaxis before symptom onset is highly effective at preventing the disease.
Can Zoonotic Rabies Be Prevented?
- Avoid Contact with Wild or Stray Animals
- Vaccinate Pets Regularly
- Seek Immediate Medical Care After Animal Bites or Scratches
- Control and Surveillance Programs – In animals to reduce rabies incidence.
