The signs and symptoms of pneumonia vary from mild to severe. Many factors affect how serious pneumonia is, including the type of germ causing the infection and your age and overall health.

Newborns and infants may not show any signs of the infection.
The three clinical forms of influenza pneumonia are primary influenza pneumonia, secondary bacterial pneumonia, and mixed viral and bacterial pneumonia. Primary influenza pneumonia manifests with persistent symptoms of cough, sore throat, headache, myalgia, and malaise for more than 3-5 days.he common constitutional symptoms of viral pneumonias are fever, chills, nonproductive cough, rhinitis, myalgias, headaches, and fatigue. Symptoms of viral pneumonia are similar to that of bacterial pneumonia, although studies have shown a lower probability of having chest pain and rigors in viral pneumonias.
