Symptoms of h7n9 infection?

In the early stage of onset, the patient presented with influenza like symptoms, including fever, cough, headache, muscle soreness and general discomfort, as well as runny nose, stuffy nose and sore throat. Some patients with severe lung disease or rapid development of disease, chest tightness and dyspnea and other symptoms.

matters needing attention

We should do a good job in monitoring the influenza of animals and people. Timely detection of animal infection or disease epidemic situation, as well as the state of virus circulation in the environment, as soon as possible to take animal immunization, culling, closed market and other measures to eliminate the source of infection, block the spread of the virus between birds. Early detection and diagnosis of avian influenza patients, timely, effective and reasonable implementation of case isolation and diagnosis and treatment. We should do a good job in the epidemiological investigation and virological monitoring of the disease, constantly enhance the scientific understanding of avian influenza, timely discover the clustering cases and virus mutation, and then take corresponding intervention and response measures.
