The novel influenza is essentially a name designated by the government to distinguish it from the seasonal strain of influenza. In other words, when people with flu-like symptoms are identified as having contracted A-type influenza but not the H1 or H3 subtype, they are regarded as suspected cases of novel influenza and shall be given antiviral drugs and preventive therapies. They need to undergo an examination to determine whether or not they have indeed contracted novel influenza, and if found positive, they shall be classified as H5 or H7 cases and will be treated accordingly. Symptoms in early period of the novel influenza are similar to those of human influenza, including headaches, muscle aches, runny nose, coughs, sore throat, and conjunctivitis (according to the H7N7-infected patient in Netherlands). Moreover, the H5N1-infected cases in Vietnam also show the symptom of diarrhea. In the later period, the patients may suffer from high fever, pneumonia, multiple organ failure, and even die.
