How long is the incubation period of rabies vaccine

If a person is bitten by a small animal, he or she is likely to develop rabies, which is very serious. People need to be vaccinated against rabies because, depending on their physical constitution, rabies cannot be cured once it occurs. Rabies is a very serious disease. People should pay attention to timely treatment. Animals are poisonous and bacteria can also occur. Therefore, rabies vaccination is the best treatment method, but rabies vaccine has a certain incubation period. How long is the incubation period of rabies vaccine?

Length and Shortness Factors

There are many factors that affect whether a person will develop symptoms after being bitten by a rabid dog:

1. It depends on the amount of rabies virus that enters the human body. If the mad dog bites a person in the early stage of the disease, the rabies virus in its saliva will be less than that in the late stage of the disease;

2. The severity of the bite also affects whether the bitten person will become ill. Large, deep bites are more likely to cause disease than small, superficial bites.

3. Multiple bites are more likely to cause disease than single bites, and the incubation period is shorter.

4. Correct and timely treatment of wounds after being bitten is the first line of defense against rabies. If the wound is treated correctly and promptly, and anti-rabies post-exposure treatment is given, the risk of the disease can be greatly reduced.

5. Infection through mucous membranes is more difficult to cause than infection through skin bites, and most cases are depressive rabies.

6. The morbidity and mortality rates of people bitten by mad animals on the head, face, neck and other parts close to the central nervous system or parts rich in peripheral nerves are higher than those bitten on the limbs.

7. People with low immunity are more likely to get sick than those with strong immunity.

After a person is bitten by an animal infected with rabies virus, there are no symptoms during the incubation period, which progresses slowly and gradually. Clinical symptoms rarely occur within 20 days, and most cases develop after 30 days or even 2 to 3 months. More than one year is extremely rare.

In the early stages of rabies, patients often have symptoms such as low fever, headache, general laziness, nausea, irritability, fear and anxiety. Then, the patient becomes extremely sensitive to stimuli such as sound, light or wind, and immediately feels a tightness in the throat when slightly stimulated. There are also abnormal sensations of numbness, itching and pain around the wounds caused by bites from sick animals, and it feels like ants are crawling on the hands, feet and limbs.

After two or three days, the condition enters the excitement phase. The patient is in a highly agitated state. The prominent symptoms are extreme fear, fear of water and wind. When encountering sounds, light, wind, etc., the muscles in the throat will experience severe spasms. Although the patient is very thirsty, he dare not drink water, and he cannot swallow the water after drinking it. Even if he hears the sound of running water or others talk about water, he will experience throat spasm. In severe cases, patients may also experience painful convulsions throughout the body, leading to difficulty breathing. Most rabies patients are conscious; however, some patients become mentally ill and talk nonsense.

After about two or three days of excitement, the patient becomes quiet, but then becomes paralyzed all over, his respiratory and circulatory systems fail, and he quickly falls into a coma, and dies after a dozen hours. The course of rabies usually does not exceed 6 days.

Hydrophobia is one of the unique symptoms of most furious rabies. Hydrophobia has not been seen in other diseases, so it is very pathogenic.

If a person is bitten by a rabid dog, will he still develop rabies decades later?

If a person does not take preventive measures in time after being bitten by a rabid dog, some people will develop the disease a few years later, but there is no scientific evidence to support the theory that the disease will develop after ten or even several decades.

What is the incubation period of rabies?

The period from when a person is infected by a pathogen to when he or she shows symptoms of the disease is called the incubation period of the disease. The incubation period of rabies is generally half a month to three months. In most cases, the incubation period is concentrated between 30-90 days. Less than 1% exceed one year, and in some cases it can reach six years. Cases shorter than 15 days and longer than 1 year are rare, and cases with an incubation period of less than one year account for more than 99% of the total cases.

Is the rabies virus resistant?

The rabies virus is not very resistant to external environmental conditions. General disinfectants, heating and sunlight can make it inactive. The rabies virus is sensitive to fat solvents such as soapy water, acids, alkalis, 45%-70% alcohol, formalin, iodine preparations, and chlorhexidine, but it is not easily inactivated by Lysol. Sulfonamides and antibiotics are ineffective against rabies virus. The virus in the brain tissue of dogs that died of the disease in the wild in winter can be stored for several months at 4°C, and has a certain resistance to dryness and repeated freezing and thawing.
