What are the symptoms of H 7n 9 20

What are the clinical signs of avian influenza?

1) Acute onset, the early manifestations are similar to common influenza, mainly fever, runny nose, nasal congestion, cough, sore throat, headache, and general malaise. Some patients may see ocular conjunctivitis.

2) The body temperature lasts mostly above 39, and the fever duration is 1 7 days, generally 2 3 days.

3) Some patients may have gastrointestinal symptoms such as nausea, abdominal pain, diarrhea, and watery stools.

4) Half of the patients had signs of lung consolidation. Blood white blood cell count (2?0～18?

3）×10?9 l, lymphocytes are mostly reduced, platelets are normal. Bone marrow aspirate shows active cell proliferation and reactive histiocytosis with hemorrhagic phagocytosis.

Some patients have elevated ALT and negative bacterial culture in throat swabs.

5) Half of the patients showed unilateral or bilateral pneumonia on chest X-ray, and a few had pleural effusion.

Symptoms: fever, usually above 38 degrees, fatigue, cough, but no or little sputum.

Laboratory tests: blood routine white blood cells are not high or low, blood lymphocytes are low, and there are patches on chest x-ray.

H7N9 nucleic acid test positive.

Patients typically present with flu-like symptoms such as fever, cough, and little sputum, which may be accompanied by headache, muscle aches, and malaise. Severe patients have rapid progression of the disease, manifested as severe pneumonia, most of the body temperature persists above 39, dyspnea, and may be accompanied by hemoptysis. Acute respiratory distress syndrome, pneumomediastinum, sepsis, shock, impaired consciousness, and acute kidney injury may progress rapidly (official explanation).

According to experts, the currently confirmed cases of human infection with H7N9 avian influenza are mainly manifested as typical viral pneumonia, with acute onset, high fever of more than 38, cough and other respiratory infection symptoms in the early stage of the disease. Dyspnea occurs 5 to 7 days after the onset of illness, severe pneumonia with progressive exacerbation, and some cases can rapidly progress to acute respiratory distress syndrome and death.

Experts believe that good hygiene habits and a healthy lifestyle can also effectively prevent respiratory infections such as influenza. These include maintaining good indoor ventilation, paying attention to personal hygiene, washing hands frequently, covering coughs and sneezes, and washing hands promptly after cleaning your mouth and nose. Minimize unnecessary contact with poultry and do not purchase live poultry without sanitary quarantine.

Contact and consumption of sick and dead livestock should be avoided. Poultry products bought at home should be washed and cooked before eating. Strengthen physical exercise, pay attention to nutritional supplementation, and ensure adequate sleep and rest to enhance immunity.

Experts stressed that once the public has symptoms of acute respiratory infection such as fever and cough, especially those with high fever and difficulty breathing, they should go to the hospital as soon as possible, and be sure to tell the doctor whether they have contact with sick poultry before the onset of the disease, and use drugs under the guidance of the doctor.

Like the symptoms of ordinary flu, some of them will develop into severe pneumonia, and some of the mild symptoms are only transient, and they cannot be distinguished without virus identification.

Cold symptoms, runny nose, nasal congestion, headache, body aches and weaknesses, sore throat, cough, fever more than 38 degrees, shortness of breath, chest tightness and shortness of breath,

H7N9 is a subtype of avian influenza. The outer membrane of the influenza virus particle is covered by two types of surface glycoproteins, a H7N9 avian influenza news.

The type is hemagglutinin (i.e., H), the first type is neuraminidase (i.e., N), and H is divided into 15 isoforms, and N is divided into 9 isoforms. All human influenza viruses can cause avian influenza, but not all avian influenza viruses can cause human influenza, among avian influenza viruses, H3, H5, H7, and H9 can be transmitted to humans, of which H5 is highly pathogenic. H3 is common in humans and dogs, and can be divided into 135 subtypes of Hxnx according to the characteristics of influenza viruses, and the H7N9 subtype avian influenza virus is one of them.

The biological characteristics, pathogenicity, and transmissibility of this virus have not been analyzed and judged.

It is avian influenza, which is caused by animals.

Avian influenza is called and is caused by live birds and birds.

H7N9 is the code name for avian influenza, which is a variant of H1N1

Patients infected with the H9N2 subtype usually have only mild symptoms of upper respiratory tract infection, and some patients do not have any symptoms at all; Patients infected with the H7N7 subtype predominantly present with conjunctivitis; Severe patients are generally infected with the H5N1 subtype virus. The patient has an acute onset and early manifestations resemble common influenza. It is mainly fever, most of which lasts above 39, and the fever lasts for 1-7 days, generally 3-4 days, and can be accompanied by runny nose, nasal congestion, cough, sore throat, headache, muscle aches and general malaise.

Some patients may have gastrointestinal symptoms such as nausea, abdominal pain, diarrhea, and watery stools. Severe patients may develop a variety of complications such as pneumonia, acute chronic respiratory distress syndrome, pulmonary hemorrhage, pleural effusion, pancytopenia, renal failure, sepsis, shock and Reye syndrome.

Symptoms such as fever, cough, sore throat, and general malaise.

What are the symptoms of 7N9 avian influenza.

1.What are the manifestations of human infection with HPAI?

After humans are infected with highly pathogenic avian influenza, the onset is very acute, and the early manifestations are similar to that of common influenza. The main manifestations are fever, most of the body temperature is above 39, lasting 1 7 days, generally 3 4 days, can be accompanied by runny nose, nasal congestion, cough, sore throat, headache, general malaise, some patients may have nausea, abdominal pain, diarrhea, watery stools and other digestive symptoms. In addition to the above manifestations, severe human infection with highly pathogenic avian influenza can also develop symptoms such as pneumonia, respiratory distress, and even death.

2.What is the key to preventing and controlling human infection with highly pathogenic avian influenza?

The key to preventing and treating human infection with highly pathogenic avian influenza is to achieve "four earlys", which refers to early detection, early reporting, early isolation, and early detection of diseases

Early detection: When you or others around you have symptoms such as fever, cough, shortness of breath, and body aches, you should go to the hospital immediately.

Early reporting: If a human case of highly pathogenic avian influenza or similar cases is detected, it should be reported to local medical institutions and disease prevention and control agencies in a timely manner.

Early isolation: Cases and suspected cases of human infection with highly pathogenic avian influenza should be isolated in a timely manner, and close contacts should be isolated or under medical observation according to the situation to prevent the spread of the epidemic.

Early**: Patients who are confirmed to be infected with highly pathogenic avian influenza should be actively treated, especially for people with other chronic diseases, as early as possible, and the vast majority of patients can be discharged from the hospital after antiviral drugs and the use of support and symptoms.

3.How can we prevent HPAI infection in our daily lives?

1. A healthy lifestyle is very important to prevent the disease. You should strengthen physical exercise, rest more, avoid overwork, do not smoke, and wash your hands frequently; Pay attention to personal hygiene and cover your mouth and nose when you sneeze or cough.

2. Keep the room clean, use washable floor mats, avoid using carpets that are difficult to clean, keep the floor, ceiling, furniture and walls clean, and ensure that the drainage channel is unobstructed; Maintain indoor ventilation by opening windows twice a day for at least 10 minutes each time, or using an exhaust fan to maintain air circulation; Try to avoid going to places with poor air circulation.

3. Pay attention to food hygiene, cook poultry meat and eggs thoroughly, and pay attention to the separation of raw and cooked food when processing and preserving food; Develop good hygiene habits, do a good job of kitchen hygiene, do not eat raw poultry meat and offal, and wash hands thoroughly after dissecting live (dead) poultry, livestock and their products.

4. When an epidemic is found, contact with poultry should be avoided as much as possible; The public, especially children, should avoid close contact with poultry and wild fowl.

5. Pay attention to the disinfection of living utensils. The avian influenza virus is not heat-tolerant and can be inactivated in 1 minute after 100 sessions. It is sensitive to dryness, ultraviolet radiation, mercury, chlorine and other commonly used disinfectants.

6. If you have fever and respiratory symptoms, you should wear a mask, see a doctor as soon as possible, and remember to tell the doctor whether there is a history of travel or contact with poultry before the onset of the disease.

7. Once you get sick, you should take medication under the guidance of a doctor, rest more, drink more water, and pay attention to personal hygiene.

b Test question analysis: A, H 7N9 virus can cause disease to humans and birds, belongs to animal viruses, A is correct; b. Humans or animals with avian influenza are the source of infection, b. Error; c. Viruses do not have a cellular structure, they are made up of protein shells and internal genetic material, c. Correct; d. Viruses must live and multiply in the living cells of other organisms, d. Therefore, b

Guidance on Careful Advice:

Hello: Consider that the situation of your lobbying is generally manifested by flu-like symptoms such as fever, cough, and low phlegm, which may be accompanied by headache, muscle aches, and general malaise. The condition of severe patients progresses rapidly, manifesting as severe pneumonia, most of the body temperature persists above 39, and dyspnea appears, which may be accompanied by hemoptysis.

Acute respiratory distress syndrome, mediastinal emphysema, sepsis, shock, impaired consciousness, and acute kidney injury can progress rapidly.
