Rabies is actually a fatal disease, with a 100% death rate once infected, so there are no treatment options available, only prevention can be strengthened. Rabies is also a very rare disease; across our country, there are approximately 40 million exposure cases each year, but only about 1,000 cases of rabies occur annually. If someone is bitten or scratched by a dog, cat, or bat, it is necessary to administer a rabies vaccine. For wounds with broken skin, rabies immunoglobulin must also be administered to ensure proper prevention.

Is rabies contagious?

Rabies is contagious; in fact, most cases of rabies result from being bitten by rabid dogs, cats showing symptoms of the disease, or bats carrying the rabies virus. There have been no reports of transmission from human to human. Rabies is a fatal disease, with a 100% mortality rate once infected. The saliva of dogs showing symptoms contains a high concentration of the virus. If one is bitten and does not receive timely prevention and intervention, there is a high likelihood of contracting the infection.

How long does rabies take to develop?

The incubation period for rabies generally ranges from one to three months, rarely exceeding one year, with the shortest onset at five days and the longest around six years. Actually, the duration of the incubation period is related to the location of the bite; the further from the head, the longer the incubation period. If the wound from the bite is superficial and contains fewer rabies viruses, then the incubation period will also be longer. Conversely, if there is a larger amount of rabies virus and the wound is deeper, the incubation period will be shorter. Rabies is a fatal disease, with a 100% mortality rate once infected.

Rabies clinical symptoms

Rabies presents with typical symptoms that usually appear two to four days before the onset, including low-grade fever, general discomfort, muscle soreness, weakness, fatigue, and loss of appetite. Some individuals may also experience irrational fear, anxiety, agitation, irritability, hyper-sensitivity, insomnia, or depression. The bitten area may also exhibit symptoms of nerve pain, numbness, itching, or a sensation similar to an ant bite. Once rabies onset occurs, it generally leads to death, and it is rare for individuals to survive more than ten days after the disease manifests.

Does rabies cause headaches and dizziness?

During the apparent symptomatic phase of rabies, symptoms like headache and dizziness may occur, although they are not the main symptoms. More typical symptoms of rabies include hydrophobia, fear of wind, photophobia, and difficulty drinking water. Exposure to bright lights and loud noises can cause whole-body spasms and pain. The disease can also cause facial muscle spasms, leading to distorted facial expressions. Subsequently, opisthotonus may occur, along with drooling, tearing, and tachycardia. Eventually, the patient may fall into a coma and die. Fever may also be present.

Rabies is transmitted by what?

Rabies is an infectious disease primarily caused by bites from rabid dogs. According to the epidemiology of rabies in our country, it is mostly contracted from dog bites when no rabies vaccine has been administered. Of course, there is also a risk of infection from scratches by cats or dogs during their infectious periods or bites from infected cats, as well as scratches from bats carrying the rabies virus. To date, there have been no reported cases of human-to-human transmission. Rabies is a fatal disease, with a 100% fatality rate upon infection, thus prevention is crucial.
