The SCARIEST Disease Ever??
Institute of Human Anatomy・16 minutes read
Rabies is a deadly disease caused by a neurotropic virus that targets the nervous system, transmitted primarily from animals to humans, with symptoms ranging from numbness to paralysis and death within days to weeks of onset. The virus spreads through the body, inducing foaming at the mouth and aggressive behavior in animals, and while it causes zombie-like symptoms, it is not classified as a zombie virus, highlighting the need for scientific accuracy in distinguishing between pathogens and diseases.
Insights
- Rabies, caused by the rabies virus, is a zoonotic disease transmitted primarily from animals to humans, with a high fatality rate due to its neurotropic nature targeting the nervous system.
- The rabies virus progresses from muscle tissue to nerves, spinal cord, and eventually the brain, causing symptoms like anxiety, paralysis, and death, emphasizing the critical role of scientific analysis in distinguishing between pathogens and diseases, despite occasional similarities to zombie behavior.

Recent questions
What is rabies?
Rabies is a deadly disease caused by the rabies virus, primarily transmitted from animals to humans, with a high fatality rate once symptoms appear.
How is rabies transmitted?
Rabies is primarily transmitted through the bite of an infected animal, with rare cases of human-to-human transmission.
What are the symptoms of rabies?
Symptoms of rabies include numbness, tingling, fever, headache, anxiety, insomnia, aggression, paralysis, nausea, vomiting, coma, and death.
How does rabies affect the body?
Rabies targets the nervous system, causing symptoms like numbness, tingling, fever, headache, anxiety, insomnia, aggression, paralysis, nausea, vomiting, coma, and death.
How is rabies prevented and treated?
Rabies can be prevented through vaccination of pets, avoiding contact with wild animals, and seeking medical attention immediately if bitten. Treatment includes post-exposure prophylaxis with a series of vaccinations.

Deadly Rabies Virus: Symptoms, Transmission, and Treatment
- Rabies is a disease caused by the rabies virus, a type of lyssavirus, capable of killing 50,000 to 70,000 people annually worldwide.
- It is a zoonotic disease, primarily transmitted from animals to humans, with rare cases of human-to-human transmission, notably through organ transplants.
- The rabies virus is neurotropic, targeting the nervous system, making it challenging to treat, with a high fatality rate once symptoms manifest.
- Incubation period ranges from one to three months, but cases have shown symptoms appearing within days or even years after exposure.
- The virus enters the body through muscle tissue, slowly replicating before targeting nerves, leading to numbness, tingling, fever, and headache.
- Progressing through nerves, the virus reaches the spinal cord, then ascends to the brain, with the location of the bite influencing the speed of progression.
- In the brain, the virus multiplies rapidly, causing swelling, leading to symptoms like anxiety, insomnia, aggression, or paralysis.
- The virus then spreads throughout the body, causing nausea, vomiting, coma, and death within 2-10 days of symptom onset.
- The virus aims to be transmitted to the next host through hypersecretion of saliva, inducing foaming at the mouth and aggressive behavior in animals.
- While biting is a common transmission method in animals, it is less frequent in humans due to different defense mechanisms, making it a less common symptom in human rabies cases.

Rabies: Not a Zombie Virus
- Rabies virus causes hypersalivation by affecting the salivary glands, while also inducing violent spasms in the pharynx and esophagus to prevent saliva from diluting the virus in the digestive tract, leading to hydrophobia in infected individuals.
- Despite similarities to zombie behavior, rabies does not classify as a zombie virus due to the sporadic aggression displayed by patients, emphasizing the importance of scientific thinking in accurately understanding and differentiating between pathogens and diseases.
