Why is there no cure for rabies?

Rabies is a viral infection of the central nervous system, and while there is no specific cure, there is a highly effective vaccine that can prevent the disease if given before symptoms develop. Once symptoms appear, the infection is almost always fatal.

The rabies virus is transmitted through the saliva of infected animals, usually through a bite. The virus travels along the nerves to the brain, where it causes inflammation and damage. The initial symptoms of rabies are similar to those of many other viral infections, including fever, headache, and muscle weakness. As the disease progresses, however, more severe symptoms develop, such as agitation, hallucinations, and hydrophobia (fear of water).

The rabies vaccine is made from a weakened form of the rabies virus. When the vaccine is given, the body's immune system produces antibodies that protect against the virus. If someone is exposed to the rabies virus after being vaccinated, the antibodies can help to prevent the infection from developing.

The rabies vaccine is very effective, but it must be given before symptoms develop. If someone is exposed to the rabies virus, they should seek medical attention immediately to receive the vaccine.
