Rabies is an infectious and complex virus that affects the central nervous system of mammals, leading to fatal brain inflammation in severe cases. It is caused by the rabies virus and is almost always fatal if left untreated. Many wild animals carry this, however; the disease is most commonly found in bats and carnivores, such as foxes, wolves, and raccoons. Treatment and vaccination is the key to preventing rabies from becoming fatal, which involves a series of vaccinations and exams to determine if a person is suffering from the disease.

What is Rabies
Rabies is a zoonotic disease that affects the central nervous system. The virus responsible for rabies, called the rabies virus, is mostly spread through the bite of an infected animal; however, other modes of transmission include scratches and mucous membrane contact. It is an often fatal neurological disease that is considered untreatable once symptoms start to manifest. Fortunately, this can be prevented through timely vaccinations to immunize both people and animals, which has been successful in drastically reducing the global burden of rabies.
Rabies is a fatal infectious disease that affects the central nervous system and it is transmitted from mammals to humans through saliva or through a bite. The virus responsible for rabies is known as the Lyssavirus and it replicates in the cells of the central nervous system, leading to the acute encephalitic phase that can cause the infected patient to suffer from restlessness, insomnia, agitation, hydrophobia, confusion, delirium, and even coma. After infection with the virus, it can take anywhere from a few days up to a year for full-blown symptoms to begin appearing. In most cases, once the symptoms appear, death comes shortly after as the virus has a high fatality rate.
Symptoms
Rabies is a viral disease that affects the central nervous system and is usually transmitted through the bite of an infected animal. Early symptoms of rabies may include fever, headache, and general weakness or discomfort. As the disease progresses, more specific symptoms may develop, such as:
Pain or tingling at the site of the bite
Anxiety, agitation, or restlessness
Confusion or abnormal behavior
Hallucinations
Insomnia
Difficulty swallowing
Excess salivation or frothy saliva
Partial paralysis
If left untreated, rabies can be fatal. It is important to seek medical attention as soon as possible if you have been bitten by an animal or if you have been exposed to rabies in any other way. A vaccine can be given to prevent the disease if administered soon after exposure.
Causes
Rabies is caused by a virus that is primarily transmitted through the bite or scratch of an infected animal. The virus is present in the saliva of infected animals and can be transmitted to humans or other animals through a bite or scratch that breaks the skin. In rare cases, this can also be transmitted through the inhalation of the aerosolized virus, such as when saliva from an infected animal is introduced into an open wound or mucous membrane.
The most common carriers of this are carnivorous animals such as dogs, cats, and bats, although any mammal can potentially transmit the virus. In some parts of the world, this is also found in non-mammalian species such as snakes and monkeys.
Rabies is rare in the United States, but it is still important to be aware of the risk of rabies transmission and to take precautions to prevent exposure, such as avoiding contact with wild animals and ensuring that domestic pets are up to date on their rabies vaccinations.
Treatment for Rabies
Treatment for rabies involves a series of steps that are typically initiated as soon as possible after exposure to the virus. The mainstays of this treatment are the administration of a rabies vaccine and the provision of supportive care to manage symptoms and prevent complications.
The rabies vaccine is typically given in a series of doses to stimulate the body’s immune system to produce antibodies that will protect against the virus. The vaccine is usually given in the muscle of the upper arm, and the number of doses and the interval between doses will depend on the specific vaccine and the person’s risk of developing rabies.
Supportive care for this may include medications to control fever, pain, and other symptoms, as well as intravenous fluids, to prevent dehydration. In severe cases, mechanical ventilation may be required to assist with breathing.
It is important to seek medical attention as soon as possible if you have been bitten by an animal or if you have been exposed to this in any other way. Early treatment can significantly improve the chances of survival and prevent the progression of the disease.
Conclusion
Rabies is an infectious disease caused by a virus that attacks the central nervous system of warm-blooded mammals, such as bats, foxes, raccoons, and cats. It is passed from one animal to another through contact with the saliva or neural tissue of an infected animal. The virus can enter the human body through the bite of an infected animal, by inhalation of the virus, or rarely, by contamination of broken skin or mucous membranes with saliva or neural tissue from an infected animal. If not treated, this is almost always fatal.
