What are the symptoms of avian influenza in a person10

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. White blood cell count (2 0 18 3) 10 9 L, lymphocytes mostly low, platelets 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.

After humans suffer from avian influenza, the incubation period is generally less than 7 days, and the early symptoms are very similar to other influenzas, mainly manifested as fever, runny nose, nasal congestion, cough, sore throat, headache, general malaise and other symptoms. Most patients have a good future, short course of disease, fast recovery, and no sequelae, but a small number of patients, especially older and late patients, will rapidly develop into progressive pneumonia, acute respiratory distress syndrome, pulmonary hemorrhage, pleural effusion and other complications that are life-threatening.

If you are infected with QLG by contact with a hen, the symptoms are to keep flapping your arms, and if you are infected with QLG by a rooster, the symptoms are to stretch your neck until you die.

Avian influenza is mainly an infectious disease caused by influenza A virus, which rarely infects humans due to species barriers. However, due to the continuous emergence of its variants, some of them have the ability to infect humans, and even caused a series of regional human infection events, posing a threat to people's lives. Among the many avian influenza subtypes that can directly infect humans discovered so far, a series of clinical symptoms and hazards caused by the highly pathogenic H5N1 and H7N9 subtypes are of particular concern.

Human infection with avian influenza virus has more severe respiratory symptoms than that of common influenza virus, and the disease progresses rapidly, with severe symptoms and even death.

After being infected with the avian influenza virus, most people will have fever symptoms, and the body temperature will continue to be above 39 degrees.

Avian influenza virus infection initially presents with similar cold symptoms to the common influenza virus, with symptoms such as cough, nasal congestion, sore throat, headache, muscle aches and general malaise, and the symptoms are severe and develop rapidly.

Some infected patients may have digestive symptoms, such as nausea, vomiting, diarrhea, and some patients may even have gastrointestinal bleeding and stress ulcers.

Almost all patients infected with avian influenza will have obvious symptoms of pneumonia, such as chest tightness and shortness of breath, cough and sputum production, dyspnea or hemoptysis, which can rapidly develop into acute lung injury, pulmonary hemorrhage and pleural effusion, acute respiratory distress syndrome, etc.

In addition to severe respiratory disease, severe patients with avian influenza can also be combined with damage or failure of other systems and organs, such as heart failure, and can be secondary to severe bacterial infection, such as sepsis, septic shock, etc., and some severe patients can have coma and consciousness disorder.

Because the early symptoms of human infection with avian influenza are difficult to distinguish from those of the common cold, and it develops rapidly and causes great harm to the body, if there are cold symptoms such as fever in the high-incidence season or high-risk areas, sufficient attention should be paid to and countermeasures should be taken as soon as possible.

Clinical presentation.

According to the incubation period of influenza and the results of the investigation of existing cases of H7N9 avian influenza virus infection, the incubation period is generally less than 7 days.

a) General performance.

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, mediastinal emphysema, sepsis, shock, impaired consciousness, and acute kidney injury can progress rapidly.

Health and Family Planning Commission).

Generally speaking, it is close contact with birds, and it has not been found that people can transmit it to people, so it should not be contagious.

The incubation period for avian influenza varies from a few hours to 3 to 5 days. The clinical manifestations of avian influenza also vary widely, ranging from asymptomatic infection to respiratory illness and decreased egg production, to acute sepsis with a mortality rate of 100%.

Infection with highly pathogenic avian influenza of the H5N1 subtype is mostly acute, often with sudden onset and death without any symptoms. The course of the disease lasts 1 to 2 days, the body temperature rises to, refusal to eat, high mental depression, head swelling, blackening and edema of the cockscomb and flesh, inflammation of the conjunctiva of the eye, and increased discharge. Difficulty breathing, often making a "strange scream" sound, and gray-red exudate, severe cases can cause suffocation and death of sick chickens.

Some sick chickens have diarrhea and nervous symptoms, and the laying hens have decreased or even stopped production, with a fatality rate of 50% 100%.

Infected with low pathogenic avian influenza (LAIAI) shows depressed spirits, decreased appetite, dyspnea, visible mucosal cyanosis, swollen head, tearing, runny nose, diarrhea and may have a brief period of fever. Egg production has dropped sharply, egg production may drop to 5% to 10%, or even be discontinued, egg quality will decline, broken eggs, sand shell eggs, soft skin eggs and malformed eggs will increase, and the mortality rate will be 10% to 40%.
