Question

On the first day, I had a bit of a cough and fever. By the third day, it seems like I have a higher fever, and the cough is about the same as the first day. My body also feels a bit sore. I want to know if I’ve changed to H7N9.

Answer

H7N9 avian influenza is a novel strain of avian influenza, characterized by symptoms such as fever and cough. Severe cases may quickly escalate to severe pneumonia, accompanied by symptoms like respiratory difficulty and hemoptysis.
