What are the symptoms of avian influenza in chickens, and what are the symptoms of avian flu

Common symptoms of chicken infection are: depression, reduced feed consumption, and emaciation; The nesting capacity of the hens is enhanced, and the egg production is reduced; The symptoms of avian influenza in humans are different from those of avian influenza in birds. According to Guo Yuanji, a researcher at the National Influenza Center of the Chinese Center for Disease Control and Prevention, the symptoms of human infection with avian influenza are very similar to those of the first infection, and it is quite difficult to identify them clinically. The incubation period of patients is generally within 7 days, and the main manifestations in the early stage are fever, runny nose, nasal congestion, cough, sore throat, headache, general malaise, some patients have gastrointestinal symptoms such as nausea, abdominal pain, watery stools, etc., and some patients will be complicated by ocular conjunctivitis, and the patient's body temperature mostly lasts above 39 degrees Celsius.

As the disease progresses, some patients develop unilateral or bilateral pneumonia, and a few have pleural effusions. A small number of patients may deteriorate and die from progressive pneumonia, acute respiratory distress syndrome, pulmonary hemorrhage, pleural effusion, renal failure, septic shock, and other complications. Guo Yuanji said that because cases of human infection with avian influenza have already appeared and shown a high mortality rate, in recent years, the international community has regarded avian influenza as a new acute infectious disease for human beings, and listed it as one of the contents of the international anti-bioterrorism.

To date, the H5N1H7N7H9N2 subtype virus has been confirmed to cause cases of avian influenza in humans. Guo Yuanji believes that while being highly vigilant against the H5N1 virus, we should also pay attention to the threat from the H9N2 subtype avian influenza virus strain, which has receptor specificity similar to the first-inducible virus, and has a certain range of infection in the population, but it is mostly inconspicuous in poultry and is not easy to be detected.

Sick chickens are depressed, feed consumption is reduced, and they are emaciated; The nesting capacity of the hens is enhanced, and the egg production is reduced; mild to severe respiratory symptoms, including coughing, sneezing, and profuse tearing; Edema of the head and face, nervous disorders and diarrhea. Any of these symptoms may occur alone or in different combinations. It is recommended to use triavian peptide for ** and prophylaxis.

Avian influenza is a common disease in people due to avian influenza virus infection, and after people suffer from this disease, their bodies will also show different symptoms, and the following article will introduce the symptoms of avian influenza.

1.Symptom 1: In the early stage of the disease, people with avian influenza will have flu-like symptoms, including fever, cough, headache, muscle aches and general malaise, but also runny nose, nasal congestion, sore throat, etc., some people have severe lung lesions or rapid disease development, chest tightness and dyspnea and other symptoms.

2.Symptom 2: Avian influenza after the onset of the disease, its respiratory symptoms appear earlier, generally within 1 week after the onset of the disease, the duration is longer, some people still have a more serious cough and sputum after 1 month, in the early stage of the disease, that is, there is chest tightness, shortness of breath and dyspnea, often indicating that the lung lesions progress rapidly, will rapidly develop into a severe hypoxia state and respiratory failure, the severe disease develops rapidly, more than 5 7 days of severe pneumonia, the body temperature mostly lasts above 39, dyspnea, It may be accompanied by hemoptysis sputum, and can rapidly progress to acute respiratory distress syndrome, sepsis, infectious Hugh nuclear jacket, and some may have mediastinal emphysema, pleural effusion, etc.

3.Symptom 3: A considerable proportion of patients with severe disease are combined with damage or failure of multiple other systems or organs at the same time, such as heart failure caused by myocardial injury, individual patients also show digestive symptoms such as gastrointestinal bleeding and emergency ulcers, and some severe patients have coma and consciousness impairment with blindness.

Precautions. In order to avoid the appearance of avian influenza, we should also pay attention to personal hygiene, maintain frequent hand washing, frequent indoor ventilation and pay attention to nutrition, especially after contact with livestock.

Today is July 22, according to the latest news reports, a boy in Hebei was unfortunately infected with H3N8 avian influenza, when the boy showed symptoms, his parents immediately took him to seek medical treatment, the boy's condition has been effectively alleviated, this virus is not terrible, and the ordinary flu is almost the same, and the current medical level is also very developed, so people do not need to worry too much, about this disease, what are the main symptoms of the disease?

Fever is one of the symptoms of avian influenza, in the early stage after the patient is infected with the avian influenza virus, there will be symptoms of fever, generally a sudden fever, the patient's body temperature is about 38 degrees Celsius or more, the patient will also have a dry mouth, the face ** redness, if this happens, you can take fever medicine at home,Physical cooling is done by wiping the body with alcohol, and if the fever is too severe and accompanied by other symptoms, then you should seek medical attention as soon as possible, seek professional help, patients are generally children with relatively low immunity.

These conditions are similar to the ordinary flu, many people will treat it as an ordinary cold, and the first result of blind examination is getting worse and worse, more and more serious, this is because there is no right medicine, the cough of general patients is common, and there will be the phenomenon of coughing up phlegm, if the cough is aggravated in the later stage, then it is likely to cause dyspneaThere will also be a lack of oxygen, which can lead to headaches, accompanied by chest tightness and shortness of breath, and muscle soreness in the body, seek professional help to avoid getting worse and infecting others.

That's all for me, I hope it can help you.

Symptoms of avian influenza in chickens: sick chickens, lack of energy, poor activity, reduced feed consumption, emaciation; The nesting capacity of the hens is enhanced, and the egg production is reduced; coughing, runny nose, sneezing and profuse tearing; Edema of the head and face, nervous disorders and diarrhea, dyspnea, sometimes disease outbreaks are rapid, and chickens are found dead in the absence of obvious symptoms. Avian influenza can be divided into three categories: acute septicaemia, acute respiratory and atypical according to different clinical symptoms and pathological changes.

1.The main symptoms of acute septicaemic avian influenza (typical avian influenza) in sick birds are high depression, lethargy, gasping for breath, tearing and runny nose (pus-like fluid from the eyes and nose can sometimes be seen in waterfowl), cyanosis, bleeding, head and neck enlargement, and acute death. In some cases, neurological symptoms such as ataxia, tremor, eccentia, and neck twisting are present.

Pathological changes are characterized by corneal opacity, conjunctival hemorrhage, ulceration; There are red-black plaque-like hemorrhages on the surface of wings and sacs; Tibial hemorrhage (reddish-brown hemorrhagic plaques on the shin scales) and edema are also common; subcutaneous edema (especially of the head, neck, and chest) or gel-like infiltrates; hemorrhagic edema in the lungs, grayish-white speckled necrosis in the spleen, brown speckled hemorrhage, degeneration, necrosis in the pancreas; bursal hemorrhage; From the oral cavity to the cloaca, the entire mucosa of the digestive tract has bleeding, ulcers, or gray-white spots, streak-like membranous (necrotizing pseudomembrane), and other tissues and organs may also have bleeding, and obvious fibrinous peritonitis, air sac inflammation, etc. are often seen. Some sick chickens have grayish-white necrotic streaks on the heart muscle. 2.

Acute respiratory avian influenza (typical avian influenza) is characterized by tearing, shortness of breath, coughing, sneezing, sinus swelling, dysentery, and some deaths (mortality is higher when co-infected with Newcastle disease virus or other avian paramyxovirus strains I). The main pathological changes are laryngeal tracheal hemorrhage, accumulation of secretions in the sinuses, edema and bleeding of the conjunctiva, and sometimes pathological changes similar to acute septicaemic avian influenza. 3.

Atypical avian influenza disease birds generally present with tearing, coughing, wheezing, diarrhea, a significant decrease in egg laying rates (50 to 80 decreases), and sporadic deaths. The general pathological changes are that there are some exudative inflammation of the sinuses, trachea, air sac, and intestine, sometimes there is fibrinous exudation of the air sac, thickening of the cyst wall, yolk peritonitis occurs in female birds, and there is inflammatory exudate in the fallopian tube.

Chickens get avian influenza**: Avian influenza special effect product - three poultry peptides, which contain refined homologous serum antibodies. Main**Chicken epidemic**Risk**Epidemic**T

Fortified triavian peptide, used alone. There is no need to take any medications.

Symptoms of chicken influenza: depressed in sick birds, reduced feed consumption, emaciation; The nesting ability of female birds was enhanced, and the egg production decreased. mild to severe respiratory symptoms, including coughing, sneezing, and profuse tearing; Edema of the head and face, nervous disorders and diarrhea. Prevention and control measures:

1. For highly pathogenic chicken influenza, comprehensive prevention and control measures should be adopted, which is "culling first, supplemented by immunization". 2. The use of three poultry peptides, which has special effects on the emergency prevention and development of chicken influenza.
