Some patients have chest tightness and dyspnea when their lung lesions are serious or their condition develops rapidly. Respiratory symptoms appear earlier, usually within 1 week after onset and last longer. Some patients still have severe cough and expectoration after treatment for 1 month. Chest tightness, shortness of breath and dyspnea in the early stage of the disease often indicate that lung lesions progress rapidly and will rapidly develop into severe hypoxia and respiratory failure.
Severe patients developed rapidly, and severe pneumonia appeared in 5 ~ 7 days. Most of them have a body temperature above 39℃, and have difficulty breathing, which may be accompanied by hemoptysis and phlegm. It can rapidly develop into acute respiratory distress syndrome, sepsis and septic shock, and some patients may have mediastinal emphysema and pleural effusion.
A considerable proportion of critically ill patients are also complicated with injuries or failures of other systems or organs, such as heart failure caused by myocardial injury. Some patients also have digestive symptoms such as gastrointestinal bleeding and stress ulcer, and some severe patients have coma and disturbance of consciousness.
Methods to prevent human infection with avian influenza
Combined with the characteristics of avian influenza virus and existing research findings, it is considered that birds carrying the virus are the main source of infection for human beings. It is particularly important to reduce and control the spread of avian influenza virus among birds, especially among birds. With the improvement of China's social and economic development level, it is urgent to speed up the transformation and upgrading of traditional poultry breeding and circulation to modern production mode, from free-range breeding mode to centralized large-scale breeding, slaughter treatment and scientific transportation, so as to improve the biosafety level of livestock breeding and circulation, thereby reducing the exposure opportunities of live or sick birds.
At the same time, continue to carry out health education, advocate and cultivate personal respiratory hygiene and preventive habits, wash hands frequently, keep the environment clean, and process and cook food reasonably. It is necessary to strengthen health education and health protection for high-risk groups and medical personnel infected with avian influenza.
At the same time, it is necessary to monitor the influenza in animals and people. Timely discover the epidemic situation of animal infection or disease, as well as the spread state of the virus in the environment, and take measures such as animal immunization, culling and closing as soon as possible to eliminate the source of infection and block the spread of the virus in poultry. Early detection and diagnosis of avian influenza patients, timely, effective and reasonable implementation of case isolation and diagnosis and treatment. Do a good job in epidemiological investigation and virological monitoring of the disease, continuously improve the scientific understanding of avian influenza, find clustered diseases and virus variation in time, and then take corresponding intervention and response measures.
