The bacterium *Streptococcus pneumoniae* was independently discovered in 1881 by Louis Pasteur and George Sternberg. It was quickly identified as a major cause of pneumonia and other serious diseases, prompting significant research into its pathology and leading to the development of effective vaccines in the 20th century.
Pneumococcal infection spreads from person to person primarily through respiratory droplets. This occurs when an infected individual coughs or sneezes, releasing bacteria into the air that can then be inhaled by others. The bacteria can also be carried in the nose and throat of healthy individuals without causing illness, who can then transmit it to vulnerable people.
