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.

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.

Symptoms of the incubation period of rabies

Rabies has no obvious symptoms during the incubation period. Some people might feel as if ants are biting at the wound site, while others may display symptoms of fatigue and lack of energy; however, the vast majority of people do not show any clear characteristic symptoms. The incubation period for rabies can range from one to three months, and it is rare for it to extend beyond one year. The duration of the incubation period is highly dependent on the location of the bite; the farther from the head, the longer the incubation period. Conversely, the closer to the head and face, the shorter the incubation period.

Symptoms of rabies

Rabies is an extremely dangerous and fatal disease. Once infected, it leads to a 100% fatality rate. When rabies presents its more typical symptoms, particularly during the furious phase, it manifests significant neurological symptoms such as hallucinations, convulsive seizures, bizarre behavior, hyperactivity, and rigid neck muscles. Symptoms show as extreme fear, with a pronounced fear of water, light, and wind, and include uncontrollable spasms of the throat muscles making swallowing difficult. It progresses to opisthotonus and ultimately results in coma and death.

How long is the incubation period for rabies?

The incubation period for rabies is generally about one to three months, and it is rare to exceed one year. Therefore, if more than three months have passed since being bitten by a dog without showing symptoms, it is largely possible to rule out rabies. Rabies is a fatal disease, with a 100% death rate once infected, mainly because the infection occurs after being bitten by rabid dogs, cats, or bats and not receiving the rabies vaccine. Rabies can only be prevented, so if there is exposure to the rabies virus, it is necessary to get vaccinated against rabies.

How long can rabies antibodies last?

Antibodies for rabies generally last for a relatively long time. According to the 2016 rabies prevention guidelines, if the rabies vaccine is administered systematically and sufficient levels of rabies antibodies are produced, then three to five years later, the vast majority of people can still detect effective levels of rabies antibodies. Nowadays, the detection of rabies antibodies is also quite convenient, so if one has been vaccinated against rabies before and is exposed again, it is possible to first test for rabies antibodies to determine whether there is a need to vaccinate again.
