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.

Does rabies transmit through saliva?

Rabies virus is primarily found in the saliva of dogs during the symptomatic phase, the saliva of cats during the symptomatic phase, and in the bodies of bats. There is a high concentration of rabies virus in the saliva of dogs during the symptomatic phase. Therefore, if one is bitten by a rabid dog, there is a significant risk of infection. It is necessary to promptly block and clean the wound, vaccinate against rabies, and administer rabies immunoglobulin injections locally at the wound site.

Does rabies spread through saliva?

Rabies is primarily transmitted through saliva. The rabies virus is likely to be present in the saliva of dogs or cats during the symptomatic phase. Dogs or cats carrying the rabies virus have a high concentration of the virus in their saliva during this phase. If bitten by an animal in this stage, there is a significant risk of infection. Prevention measures should be based on the actual situation, including vaccination against rabies and local administration of rabies immunoglobulin at the wound site. Rabies is a fatal disease with no treatment available, but it is preventable.

Does rabies cause coughing?

Rabies generally does not cause severe coughing, but in the late stages of the disease, coughing can occur. Eventually, due to spasms and paralysis of the respiratory muscles, some sputum cannot be expelled, which stimulates the respiratory tract to produce more secretions, possibly leading to frequent coughing. The main symptoms of rabies are a distinct fear and restlessness towards water, light, and wind. Rabies ultimately leads to death due to respiratory muscle failure and paralysis of the respiratory system.

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.

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.
