Infected avian influenza usually manifests as acute onset, with symptoms of respiratory infection such as high fever (38℃) and cough in the early course, such as dyspnea, severe pneumonia, increase, rapid development, acute respiratory distress syndrome and death in some cases. Once the disease occurs, the diagnosis and treatment are not timely, the prognosis is poor and the mortality rate is high.
No close contacts of H7N9 avian influenza, fever or respiratory symptoms were found. After medical observation, it was found that there was no human-to-human transmission, and there was no epidemiological correlation in case finding. According to the World Health Organization, this is the first case of human infection with H7N9 avian influenza virus, and no human-to-human transmission of the virus has been found. Highly sporadic diseases, there is no evidence to support the possibility of an outbreak.
However, we can't take it lightly. Viruses can be more suitable for human reproduction and human-to-human transmission through mutation and recombination with other influenza viruses. Therefore, it is very important to strictly observe the epidemic situation and scientifically analyze and protect it.
How to Identify and Treat H7N9 Avian Influenza
(Poultry and its secretions, excreta contact disease, history of poultry contact, history), according to the epidemiological contact history of patients, clinical manifestations and laboratory diagnostic test results of human infection with H7N9 avian influenza. It is unknown in the case of epidemiological history. According to the clinical manifestations, laboratory examination and laboratory test results, especially the H7N9 avian influenza virus isolated from the patient's respiratory secretions, the H7N9 avian influenza virus can be diagnosed if its nucleic acid test is positive.
Clinical diagnosis and confirmed patients should be treated in isolation, symptomatic treatment, oxygen inhalation, antipyretic drugs, cough relieving and expectorant, and antiviral therapy should be used as far as possible in the application of influenza antiviral drugs. According to the experience of other types of neuraminidase inhibitors in antiviral treatment of influenza, it may be effective in the early stage of the disease, but the specific treatment of H7N9 avian influenza virus remains to be observed and studied.
How to prevent H7N9 avian influenza, good living habits, standardize occupational protection and get necessary vaccination information in time.
Healthy lifestyle is the key to prevent H7N9 avian influenza and other infectious diseases.
In daily life, we should pay attention to strengthening physique and increasing nutrition, pay attention to ventilation indoors, wash our hands in time and effectively, and try to buy poultry products at regular sales points. Poultry meat should be cooked and cooked thoroughly before eating. People who are in close contact with poultry should pay attention to self-protection, wash their hands frequently and wear masks to avoid injury. In order to keep an eye on the development trend of the epidemic, once the epidemic intensity increases obviously, the protective measures should be adjusted in time. Symptoms of respiratory infection, should be promptly to the hospital.
Eat cooked food, not raw eggs. Avian influenza virus is not heat-tolerant, and it is inactivated at 100℃ 1 min.
Special attention should be paid to avoid direct contact with sick birds or poultry and livestock.
