Leigh Vinocur, MD, Emergency Medicine, answeredThe most dangerous and lethal super infections are secondary pneumonias that typically develop after the flu. In fact, this is what leads to the 500,000 deaths worldwide from influenza. Like bacterial sinusitis, secondary pneumonia develops as you recover from the flu. Suddenly, you get very sick with high fever, chills, shortness of breath, wheezing and trouble breathing. If this happens to you or a family member, you must see your doctor or go to the emergency department right away. If you have any signs of respiratory distress, such as severe trouble breathing with a bluish tinge to your lips or nail beds, call 911 immediately.
