Streptococcus pneumoniae

Streptococcus pneumoniae is a type of bacteria that can cause various infections, most commonly pneumonia, which is an infection of the lungs. It can also lead to ear infections, sinusitis, and meningitis (infection of the brain's protective membranes). This bacterium spreads through respiratory droplets, like those from a cough or sneeze. While it typically affects young children and older adults, healthy individuals can also become infected. Vaccines are available to help prevent serious illness caused by S. pneumoniae, making it a significant focus in public health to reduce its impact on vulnerable populations.
