Primary influenza bleeding, petechial hemorrhages, hemorrhagic syndrome. From the first day begins with a cough, mucous and bloody sputum. Physical evidence indicates the presence of pneumonic lesions of various sizes and localization. These early detected, mainly haemorrhagic pneumonia are of an extremely severe and produce a high percentage of rapidly advancing (2-5-day sickness) deaths.
