The Deadly Virus That Haunts Humanity: Rabies

🦠Rabies is caused by the lyssavirus, which has only five genes but can solve complex problems to infect and replicate in a host.

🧠The lyssavirus targets nerve cells and uses the cell's own transportation system, microtubules, to spread throughout the body.

🚫Rabies evades the immune system's defenses by blocking the production of interferons, which are key in fighting viral infections.

💀Once the lyssavirus reaches the brain, it causes encephalitis, leading to organ failure and death.

💉Vaccination is the most effective way to prevent rabies infection, as it prepares the immune system to fight the virus.

How does rabies spread to humans?

—Rabies is typically transmitted through the bite of an infected animal, such as a dog or bat, that carries the lyssavirus in its saliva.

What are the symptoms of rabies infection?

—Symptoms of rabies include fever, headache, anxiety, confusion, paralysis, and difficulty swallowing.

Can rabies be cured if symptoms appear?

—Unfortunately, there is no known cure for rabies once symptoms appear. Treatment focuses on relieving symptoms and providing supportive care.

Is rabies common in humans?

—Rabies cases in humans are relatively rare, but the virus is still a significant public health concern, especially in regions where vaccination rates are low.

How can rabies be prevented?

—The best way to prevent rabies is to vaccinate pets, avoid contact with wild animals, and seek medical attention immediately if bitten by any animal.
