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.

Why is rabies afraid of water?

The reason why rabies fears water is because the rabies virus proliferates extensively in the brain, causing massive damage to brain tissues and cells. When it affects certain swallowing nerves and glossopharyngeal nerves, and causes extensive necrosis of brain and liver cells, these symptoms will appear. In addition to fearing water, there is also a fear of bright light, wind sounds, and noise. There will be evident fear-induced spasms, and eventually, it leads to death due to coma, and it is also prone to fever.

Can rabies be transmitted?

Rabies is primarily caused by not getting vaccinated after being bitten by a rabid dog; this has been found in epidemiological studies in our country. In addition to bites from rabid dogs, there are also instances of people being bitten or scratched by cats, or bitten by bats, though these are relatively less common. So far, there have been no cases found of transmission from human to human. Rabies is a fatal disease; once infected, the mortality rate is 100%. Therefore, after being bitten by a dog, it is crucial to take preventive measures, treat the wound, and administer rabies vaccine and rabies immunoglobulin to generally prevent infection.

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.

Can rabies be contagious?

Rabies is contagious and is primarily transmitted through bites from infected dogs, cats, or bats. During the onset of the disease, the saliva of rabid dogs contains a high concentration of the rabies virus. Similarly, the saliva of cats in the onset phase also contains a large amount of the rabies virus. If these rabies viruses enter the human body, there is a significant risk of infection. Currently, transmission of rabies from one person to another is extremely rare; it is mainly transmitted to humans through bites from infected animals during their symptomatic phase.
