The rabies virus is a deadly virus that primarily affects mammals, including humans. It is usually transmitted through the bite of an infected animal, such as a dog or bat. Once inside the body, the virus travels along the nerves to the brain, where it can cause severe inflammation and neurological symptoms. Symptoms of rabies can include fever, confusion, and paralysis, often leading to death if not treated promptly. Vaccination is available for both humans and animals, making it crucial to seek medical attention after potential exposure to the virus. Early intervention can prevent the onset of symptoms and save lives.
