[h=3]Is Bacterial Pneumonia
Contagious?[/h]
Whether or not bacterial pneumonia is
contagious depends upon the type of bacteria causing the infection. In many cases, people contract pneumonia when bacteria they normally carry in the nose or throat are spread to the lungs. Most kinds of bacterial pneumonia are not highly contagious. However, pneumonia due to
Mycoplasma pneumoniae and tuberculosis are exceptions. Both these types of bacterial pneumonia
are highly contagious. These are spread among people by breathing in infected droplets that come from coughing or sneezing, similar to the spread of viral infections.
