What are the symptoms of H7N9 influenza A

Influenza A is a respiratory infection caused by influenza A virus with symptoms including fever, cough, sore throat, runny nose, muscle pain and fatigue. Ordinary people can take the following scientific methods to deal with influenza A:

Infection prevention: Maintain good personal hygiene, such as washing hands frequently, avoiding crowded public places, and avoiding contact with infected people as much as possible.

Fitness: Exercise properly, maintain a good physique, and enhance the body's immunity.

Pay attention to rest: ensure adequate sleep, avoid excessive fatigue, and let the body get enough rest.

Healthy diet: Eat a healthy and varied diet, pay attention to a balanced mix of nutrients, and consume foods rich in vitamins and minerals in moderation.

Seek medical attention in time: If you have fever, cough and other symptoms, you should go to the hospital in time, receive professional ** and care, and use drugs according to the doctor's instructions**.

In conclusion, the key to preventing influenza A is to strengthen personal hygiene habits and maintain good lifestyle habits, while actively responding to the disease and seeking medical attention in a timely manner** to reduce the risk of infection.

1.Clinical presentation.

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.

2.Diagnostic criteria.

1) Suspected cases: meet the above clinical symptoms and blood routine, biochemical and chest imaging characteristics, positive general primers of influenza A virus and exclude seasonal influenza, and can have epidemiological contact history.

2) Confirmed case: meet the diagnostic criteria for suspected cases, and H7N9 avian influenza virus or H7N9 avian influenza virus nucleic acid test positive are isolated from respiratory secretion specimens.

Recommendation: Minimize unnecessary contact with poultry, especially sick and dead poultry. Wash your hands frequently, keep away from poultry secretions, and clean your hands thoroughly with disinfectant and water if you have been in contact with birds or bird droppings. Reference.

Based on the patient's condition, I have summarized the following points:

1.Fever, cough and other respiratory tract infections, basic symptoms of cold2Chest tightness, symptoms of pneumonia, difficulty breathing.

Among them, the symptoms of pneumonia are the most significant.

According to the landlord, there should be no h7n9, of course, the landlord needs to wash his hands frequently, open the window for ventilation, wear a mask when he goes out, go to less dense places, and stay away from poultry. . . I wish you all good health!

Influenza A virus subtype H7N9 (denoted A(H7N9) or H7N9) is an influenza A virus that is a subtype of avian influenza virus or avian influenza virus. Director of the Centre for Infection and Infectious Diseases at HKU, Mr Ho Pak-leung, said that the H7N9 virus is fatal from human transmission, and the situation is unique, and the virus may have genetic changes, so it is necessary to strengthen surveillance. Yuen Kwok-yong, chair professor of the Department of Microbiology at the University of Hong Kong, said that H7N9 was originally a low-pathogenic virus with a low mortality rate, but this case has a high mortality rate and a serious condition, and the virus may have been genetically altered or genetically shuffled to become highly pathogenic avian influenza, but it is difficult to infer whether it is related to the discovery of more than 10,000 dead pigs in the Huangpu River in Shanghai earlier.
