UES: Initially pneumonia can be contagious after few days it should not be contagious any more.

Not really: Bacterial pneumonia is usually caused by aspiration ( meaning inhaling secretions) in the mouth and throat) that are colonized with bacteria. You do not typically catch "pneumonia" from someone in the same way you catch a cold, from inhaled droplets from someone else. Exceptions for some infections, like TB or legionella pneumonia exist, but most bacterial pneumonia is not contagious in this way.
