The cat is infected with symptoms of rabies

       Rabies, also known as hydrophobia, is an acute viral infectious disease that invades the central nervous system. All warm blooded animals, including humans, may be infected. It’s mostly from sick animals biting people. It is generally believed that mad dogs with white bubbles at the mouth bite the infection. In fact, cats, ferrets, raccoons, skunk, foxes or bats can also be infected and infected. Sick animals often become very savage, and the virus in their saliva passes from the bite wound to the next patient.

       It is very rare for rabies to spread from one person to another. Most of the human patients with rabies will die. There was a cured case in 1971. In 2004, after the death of an undiagnosed rabies patient in the United States, three people who received the donation died of rabies.

       morbidity

       About 15-20% of the patients bitten by dogs and 50% of those bitten by sick wolves. The incidence and the length of incubation period are related to the following factors: ¢Ù the site of bite. The patients who bite the head, neck and hand are more likely to suffer from the disease with shorter incubation period, while those who bite on the lower limbs are the opposite. ¢Ú Degree of trauma. The patients with large and deep trauma and multiple injuries had more morbidity and shorter incubation period. ¢Û Local treatment. After appropriate treatment, the incidence of the disease was less and the incubation period was longer. ¢Ü The clothes are thick and thin. The patients with thick clothes at the bite site had less morbidity and longer incubation period. ¢Ý The use of adrenocortical hormone and mental over tension (such as fear of rabies), sometimes can induce this disease. Rabies virus has a strong affinity for the nervous system. After entering the human body, the virus mainly spreads and spreads along the nervous system. After entering the human body, the virus first propagates in the skeletal muscle and nerve of the wound. This is called a local small amount of breeding period. This period can be as long as 72 hours, as long as several weeks, months or even longer. After a small amount of local reproduction, the virus invades the nerve endings, pushes along the peripheral nerve at a speed of 3 mm per hour to the central nerve, and then propagates in large quantities after reaching the spinal cord, and spreads throughout the whole nervous system 24 hours later. Later, the virus spread along the peripheral nerve to the peripheral nerve, and finally reached many organs, such as salivary glands, taste buds, corneas, muscles, skin, etc. because the nerves in the head, face, neck, hand and other parts are relatively rich, the virus is easy to reproduce, and the distance from the central nervous system is relatively large, so these parts are bitten and the incubation period is shorter. The more serious the injury, the more likely it is Illness. In the central nervous system of the virus, the vagus nucleus, the glossopharyngeal nucleus and the hypoglossal nucleus are the main ones. These nerve nuclei mainly innervate the swallowing and respiratory muscles. After being invaded by rabies virus, they are in a highly excited state. When drinking water, you can hear the sound of running water. When you are stimulated by sound, wind and light, you can make the swallowing and breathing muscles spasm, causing dysphagia and breathing difficulties. If the virus mainly invades the medulla oblongata and spinal cord, it does not show spasm clinically, but shows various paralysis (paralysis type), but is relatively rare.

       Pathological changes and clinical manifestations

       Similar to general viral encephalitis, the most specific and diagnostic change is the presence of Negri’s bodies (an eosinophilic inclusion body in the cytoplasm of nerve cells in 80% rabies patients), round or oval, with a size of 3-10 ¦Ì m, neat edges and 1-2 nuclear like dots. It is most common in pyramidal cells of hippocampus and Purkinje cells of cerebellum. Negri’s small body has been confirmed to be a virus colony. Under the electron microscope, it can be seen that there are rod-shaped virus particles in the body. If such small lesions are found in human brain or animal brain cells, the diagnosis can be made.

       Clinical stage and manifestation

       The clinical manifestations of rabies can be divided into four stages.

       1. Incubation period: (average about 4-6 weeks, the shortest and longest range can be up to 10 days to 8 months). According to the individual constitution, the incubation period varies from a few days to several years. In the incubation period, the infected person has no symptoms.

       2. Prodromal stage: the infected person begins to appear the symptoms of general discomfort, fever, fatigue, restlessness, pain of bitten parts, abnormal sensation, etc.

       3. Exciting period: Human: Patients with various symptoms to the peak, appear mental tension, general spasm, hallucinations, delirium, fear of light, fear of sound, fear of water, fear of wind and other symptoms, so rabies is also known as hydrophobia, patients often because of throat spasm and suffocation death.

       4. Coma period: if the patient can survive through the exciting period, he will enter the coma period. In this stage, the patient is in a deep coma, but the symptoms of rabies are no longer obvious. Most of the patients who enter this stage eventually die of exhaustion.

       The incubation period of the disease is 10 days to more than 1 year, and the longest is 6 years. There are two clinical types, excitatory type (typical) is the most common type, and paralytic type is occasionally seen. The excitatory type can be divided into prodromal stage, excited stage and paralytic stage. The prodromal period lasts for 1-4 days. It mainly shows local abnormal sensation. There are numbness, itching or pain near the healed wound and its neural pathway. There may be intermittent radiative tingling at the distal end of the wound, and ants walking sensation in the limbs. At the same time, systemic symptoms such as low fever, headache, fatigue, irritability, fear and uneasiness are often found, followed by the sound Light, wind and other stimuli are sensitive and throat tightness. The excitatory period lasts for 1-3 days, mainly manifested as fear of water, wind, sound, light and excitement. The most typical symptom is fear of water: drinking water, smelling the sound of running water and even talking about drinking water can induce severe pharyngeal muscle spasm. Therefore, they are often thirsty and dare not drink, and can not swallow after drinking. Breeze, sound and touch can also cause spasm of pharyngeal muscles. Severe spasm can be accompanied by respiratory muscle spasm and dyspnea, and even convulsion. The autonomic nervous system was also hyperactive, manifested as sweating, increased heart rate, increased blood pressure and increased salivary secretion. Because cannot drink water and perspiration, so often have dehydration. The body temperature often rises to 38-40 ¡æ. Most of them are clear in mind, and occasionally have mental disorder, delirium and auditory hallucination, but biting is rare. The paralysis lasted for 6-18 hours. Patients gradually quiet, spasm stopped, a variety of paralysis, in which limb paralysis is more common. There are also paralysis of eye, facial and masticatory muscles, characterized by ocular dyskinesia, mandibular ptosis, saliva flow at the mouth, as well as aphasia, hypoesthesia, disappearance of reflex, mydriasis, weak or irregular respiration, coma, and rapid death due to respiratory and circulatory failure. The average duration of the disease is 4 days, usually no more than 6 days, more than 10 days is very rare. The prodromal stage of the paralytic type also shows fever, headache, general discomfort and abnormal sensation of the bite site, followed by various kinds of paralysis, such as limb paraplegia, ascending spinal cord paralysis, etc., and finally often died of respiratory muscle paralysis. The course of this type can be longer, about 7-10 days.

       Diagnosis: if there is a history of rabies and typical symptoms (such as hydrophobia, etc.) bitten by rabies animal (if it has been attacked at the time of biting or confirmed as rabies by pathological examination of its brain), the initial diagnosis can be made if the animal has a history of biting and typical symptoms (such as hydrophobia). The diagnosis can be made by brain examination after death (Negri body positive, rabies virus antigen positive or rabies virus isolated). It should be distinguished from rabies like hysteria and encephalomyelitis after rabies vaccination.

       Rabies can be diagnosed by clinical symptoms or laboratory tests.

       1. Clinical diagnosis: mainly according to the above-mentioned clinical symptoms.

       2. Laboratory diagnosis: intracerebral basal body test; fluorescent immunoassay for antibody; secretion animal inoculation test; serological antibody test; reverse transcription PCR method for detection of viral RNA.

       Generally speaking, the symptoms of a cat are fear of light, can’t drink water, bite people randomly, and finally die of exhaustion.

       In the early stage of the disease, it will hide in the dark, do not listen to the call, and even the owner will force it to bite.

       symptom

       There was no excitatory period and hydrophobia, but high fever, headache, vomiting, pain at the bite site began, then limb weakness, abdominal distension, ataxia, muscle paralysis, fecal incontinence, etc. The course of the disease lasted for 10 days, and eventually died of respiratory muscle paralysis and bulbar palsy.

       prevention

       1. Managing sources of infection

       Vaccinate domestic animals and manage stray animals. The brain of the animal suspected to have died of rabies should be examined, burned or buried deeply, and must not be peeled or eaten.

       2. Treat the wound properly

       After being bitten or scratched by an animal, the wound should be washed repeatedly with 20% soapy water immediately. If the wound is deeper, a catheter should be inserted into the wound, and continuous perfusion with soapy water should be used to remove dog saliva and squeeze out dirty blood. When the wound is sutured deeply, it is not necessary to use anti-bacterial drugs.

       3. Vaccination against rabies

       Vaccination has positive value in preventing disease, including active immunity and passive immunity. Once a person is bitten, vaccination is very important. In severe cases, rabies serum should be injected.

       It can be divided into violent type and paralytic type

       Prodromal period

       The prodromal period is usually 1-2 days,

       Sick dog

       Mental disorders, like hiding in the dark, some sick dogs show restlessness, abnormal behavior, sometimes irritable voice, with the front paw ground, sit restless, pupil dilation. The excitation period is generally 2-4 days, the sick dog reflex excitability significantly increased, especially after being stimulated, such as by light, sound and touch stimulation can appear high panic. Dogs like to eat

       Hindquarters

       The period of paralysis is about 1-2 days. The dog’s jaw is sagging, the tongue is out of the mouth, salivation is obvious, emaciated, hind body is paralyzed, walking is swaying and lying on the ground is unable to rise

       Respiratory center

       To die of paralysis or exhaustion

       course of disease

       More often in 6-9 days

       Mental disorders, like hiding in the dark, irritable, restless, pupil dilation.

       After rabies virus enters the human body, it first infects muscle cells, proliferates in muscle cells near the wound, and then invades the peripheral nerve nearby. Then the virus spread centripetally along the axons of the peripheral nerves to the central nervous system, but did not spread into the blood. It mainly invaded the brain and cerebellum.

       Viral replication in the gray matter, along the nerve down to salivary glands, cornea, nasal mucosa, lung, skin and other parts.

       Extended data:

       In case of being bitten or scratched by a dog or cat, three steps should be taken immediately:

       Step 1: rinse the wound. Immediately wash the wound with flowing water, wash away the virus as much as possible, and squeeze the blood out. If possible, it is best to rinse with 20% soapy water for 20-30 minutes. Then disinfect the wound with iodine, then wash out the iodine with alcohol, and repeat for 3 times.

       Step 2: go to the local epidemic prevention department for vaccination immediately. Never wait a few days to get the injection. The incubation period of rabies is fast about 10 days, and the slow one may be several years.

       Step 3: if the wound is bitten seriously, be sure to inject antiviral serum and use it together with the vaccine. But the antiviral serum may be allergic, so the injection must be tested under the guidance of a doctor.

       Teach you a relatively simple method to identify whether there is a disease, you pick off the eye fundus of your pet, if the color of the eye fundus is pink or white, then don’t worry. If it is covered with blood, red is very abnormal, and the corners of the mouth have mucus constantly flowing down, then ten have a disease. Generally, domestic pets will not get rabies. When taking them out, try not to pick them up with wild dogs, because some wild dogs look normal, but in fact they carry germs. As for the crazy running around, most of the dogs are like this. They are a kind of self entertainment. Sometimes when they are torn and beaten together, they will make sounds like wild animals. This is not necessary to worry about. It is normal. The two key parts are the fundus of the eye and saliva. The earliest symptoms are like this. Although it is not easy to detect, it can be seen from a targeted look.

In 2004, a patient in the United States who was not diagnosed with canine disease died after donating viscera. Three people who received the donation died of rabies.

       Clinical stage and manifestation

       The clinical manifestations of rabies can be divided into four stages.

       1. Incubation period: (average about 4-6 weeks, the shortest and longest range can be up to 10 days to 8 months). According to the human nature, the incubation period varies from several days to several years. In the incubation period, the infected person has no symptoms.

       2. Prodromal stage: the infected person begins to appear the symptoms of general discomfort, fever, fatigue, restlessness, pain of bitten parts, abnormal sensation, etc.

       3. Exciting period: Human: Patients with various symptoms to the peak, appear mental tension, general spasm, hallucinations, delirium, fear of light, fear of sound, fear of water, fear of wind and other symptoms, so rabies is also known as hydrophobia, patients often because of throat spasm and suffocation death.

       4. Coma period: if the patient can survive through the exciting period, he will enter the coma period. In this stage, the patient is in a deep coma, but the symptoms of rabies are no longer obvious. Most of the patients who enter this stage eventually die of exhaustion.

       The incubation period of the disease is 10 days to more than 1 year, and the longest is 6 years. There are two clinical types, excitatory type (typical) is the most common type, and paralytic type is occasionally seen. The excitatory type can be divided into prodromal stage, excited stage and paralytic stage. The prodromal period lasts for 1-4 days. It mainly shows local abnormal sensation. There are numbness, itching or pain near the healed wound and its neural pathway. There may be intermittent radiative tingling at the distal end of the wound, and ants walking sensation in the limbs. At the same time, systemic symptoms such as low fever, headache, fatigue, irritability, fear and uneasiness are often found, followed by the sound Light, wind and other stimuli are sensitive and throat tightness. The excitatory period lasts for 1-3 days, mainly manifested as fear of water, wind, sound, light and excitement. The most typical symptom is fear of water: drinking water, smelling the sound of running water and even talking about drinking water can induce severe pharyngeal muscle spasm. Therefore, they are often thirsty and dare not drink, and can not swallow after drinking. Breeze, sound and touch can also cause spasm of pharyngeal muscles. Severe spasm can be accompanied by respiratory muscle spasm and dyspnea, and even convulsion. The autonomic nervous system was also hyperactive, manifested as sweating, increased heart rate, increased blood pressure and increased salivary secretion. Because cannot drink water and perspiration, so often have dehydration. The body temperature often rises to 38-40 ¡æ. Most of them are clear in mind, and occasionally have mental disorder, delirium and auditory hallucination, but biting is rare. The paralysis lasted for 6-18 hours. The patient became more and more quiet, spasm stopped, and various kinds of paralysis appeared, among which limb paralysis was more common. There are also paralysis of eye, facial and masticatory muscles, characterized by ocular dyskinesia, mandibular ptosis, saliva flow at the mouth, as well as aphasia, hypoesthesia, disappearance of reflex, mydriasis, weak or irregular respiration, coma, and rapid death due to respiratory and circulatory failure. The average duration of the disease is 4 days, usually no more than 6 days, more than 10 days is very rare. The prodromal stage of the paralytic type also shows fever, headache, general discomfort and abnormal sensation of the bite site, followed by various kinds of paralysis, such as limb paraplegia, ascending spinal cord paralysis, etc., and finally often died of respiratory muscle paralysis. The course of this type can be longer, about 7-10 days.

       Diagnosis: if there is a history of rabies and typical symptoms (such as hydrophobia, etc.) bitten by rabies animal (if it has been attacked at the time of biting or confirmed as rabies by pathological examination of its brain), the initial diagnosis can be made if the animal has a history of biting and typical symptoms (such as hydrophobia). The diagnosis can be made by brain examination after death (Negri body positive, rabies virus antigen positive or rabies virus isolated). It should be distinguished from rabies like hysteria and the brain and spinal cord after rabies vaccination.

       Rabies can be diagnosed by clinical symptoms or laboratory tests.

       1. Clinical diagnosis: mainly according to the above-mentioned clinical symptoms.

       2. Laboratory diagnosis: intracerebral basal body test; fluorescent immunoassay for antibody; secretion animal inoculation test; serological antibody test; reverse transcription PCR method for detection of viral RNA.

       Generally speaking, the symptoms of a cat are fear of light, can’t drink water, bite people randomly, and finally die of exhaustion.

       If the cat is still healthy ten days after the cat bites you, the prevention can be terminated. Of course, it should be prevented first. However, if the cat is still OK after 10 * *, you don’t have to worry about it

       If it’s gone in less than 10 days, it’s recommended to deal with rabies vaccine injection. If necessary, it needs to be injected with human rabies immunoglobulin or anti rabies serum (due to the slow excretion from the body, human rabies immunoglobulin is more popular). The earlier the wound is treated and the vaccine is injected, the better. However, the vaccination before the onset of the disease is OK, as long as the antibody level reaches the standard in time

       The main early manifestations of mad animals are marked changes in mood, such as worry or fear, and nervousness. Some sick animals are extremely friendly to their owners and beg for mercy, but they will bite people under slight stimulation and take the initiative to attack strangers; some are aloof and alone and do not stay with other animals, so they have no feelings for their owners; some have strange eating habits, such as eating soil, biting grass, biting wood, etc. It is difficult to find these abnormal manifestations without careful observation. Crazy animals in the early stage of disease, saliva contains a large number of rabies virus, at this time if they are close to, play with or be bitten (scratched) injury, they are easy to be infected and get sick.

       After the early onset of the disease, crazy animals enter the excited period, which is characterized by restlessness, running around, biting and barking impermanently. At this time, they can no longer identify strangers and acquaintances, and attack people crazily. Many people are bitten at this time. After entering the late stage, the sick animals quickly developed dyspnea and died of systemic failure.

       It should be noted that a small number of crazy animals are “quiet type”, that is, there is no obvious excited performance, but it may lead to rabies after hurting people.

       Hello! The symptoms of rabies in cats are the same as those in dogs. At the beginning of the disease, cats usually hide in the dark and don’t listen to people’s calls. Even their owners force them to bite people. After two days, they run around, often biting people and animals violently, holding their tails and drooling a lot. After three or four days, they are paralyzed and stop eating, Tongue extension, dyspnea, foaming at the mouth, ankylosis of limbs, and death due to multiple organ failure. You have been scratched by a wild cat’s tooth and may be infected with rabies virus. It is suggested that you should wash the wound with clean water or alkaline soapy water in time, disinfect the wound again in the hospital within 24 hours after injury, and inject rabies vaccine. This is the correct prevention and control measures. If you use observation, you will miss the best time for rabies vaccination. I wish you good health!

       Teach you a relatively simple method to identify whether there is a disease, you pick off the eye fundus of your pet, if the color of the eye fundus is pink or white, then don’t worry.

The earliest symptoms are like this. Although it is not easy to detect, it can be seen from a targeted look.

       Cat rabies and dog rabies are similar.

       In the early stage, they are depressed, afraid of light and dark, slow reaction, do not listen to the master’s call, do not want to contact people, abnormal appetite, like to eat foreign bodies, difficulty in swallowing and neck extension, fear of wind and water, increased saliva, hind drive weakness, pupil dilation

       Generally, 1-2 days later, they enter into the exciting period, manifesting as violent and restless, actively attacking people and other animals;

       Then it enters the paralytic apparatus, and the respiratory system declines and dies.

       You said your cat’s situation is more dangerous, be careful not to be hurt by it. But it’s also possible that the cat is poisoned!

       If your cat is OK in the end, I suggest you should give it rabies vaccine to prevent it!

       Rabies is characterized by restlessness, disorder of consciousness, excessive response to environmental stimuli, attacks on other animals, and finally paralysis and death.

       Transmission: the main source of infection of the disease is diseased and infected animals. The virus was mainly found in the saliva of the diseased animals. The virus was carried 15 days before the onset of clinical symptoms and 10 days after the symptoms disappeared. Healthy cats were mainly infected by wounds (skin scratch, bite, mucosal damage). It can infect people.

       Symptoms: the incubation period varies according to the wound site and virus content. In the early stage, the sick cat hides in the dark place, barks, resists excessively, and reacts actively to sound and light; afterwards, he is manic and restless, aggressive, or bites himself; his eyes are fierce and straight, and he does not listen to the master’s command and salivates; his spirit gradually becomes depressed and unsteady, and his hind limbs are paralyzed and falls to the ground and dies due to systemic exhaustion. The course of disease ranged from 2 to 4 days.

       Initial stage: the cat may have abnormal behavior, such as fatigue or hyperactivity, which may show sudden changes in temper or lifestyle.

       Medium term: the cat wanders around, unconscious movement, indifferent to its owner, and has a slight breath sound similar to “Herr” (mainly caused by salivary gland secretion and facial / pharyngeal muscle spasm) looking at the air, biting and barking.

       End stage: cats are afraid of water, sound, light, smell, random muscle spasm and salivation. Most cats are aggressive.

       Death period: the spirit turns to depression. Most of the limbs are stiff and difficult to breathe. Foaming occurs at the mouth. Multiple organ failure of the whole body causes death / also death due to respiratory depression.

       Rabies (rabies) is an acute infectious disease caused by rabies virus. It is common to both humans and animals. It i
