Influenza A H7 viruses are a group of influenza viruses that normally circulate among birds. The avian influenza A(H7N9) virus is one subgroup among the larger group of H7 viruses. Patients with this infection have had severe pneumonia.

Symptoms include fever, cough and shortness of breath. However, information is still limited about the full spectrum of disease that infection with avian influenza A(H7N9) virus might cause.

People mainly become infected with avian influenza through close contact with infected birds and poultry (live or dead) or their droppings. Human-to-human transmission is inefficient.
