According to Dr. Panda, viral pneumonia is more contagious and can spread through droplets released during sneezing and coughing. If an infected person coughs or sneezes, the infection may be passed to a healthy person. The chances are higher in viral pneumonia as compared to bacterial pneumonia. Viral pneumonia can have severe consequences like breathlessness that may require hospitalisation.
Viral pneumonia and bacterial pneumonia are different in terms of clinical presentation. For example, a patient might experience influenza, concomitant gastrointestinal symptoms, moderate to high fever, viral infection in the respiratory tract, etc. if they have viral pneumonia. These symptoms would gradually worsen.
Bacterial pneumonia, on the other hand, is faster in causing severe symptoms. The symptoms would be rapid in this case and you may experience severe complications within a couple of days of the bacterial infection. Therefore, it is important to seek treatment for all types of pneumonia as soon as you begin to experience its symptoms.

Couse of antibiotics is defined for bacterial pneumonias.
