Streptococcus pneumoniae, also known as pneumococcus, is a type of bacteria that can cause a variety of infections in humans, including pneumonia, meningitis, and sepsis.

The bacteria are commonly found in the upper respiratory tract of healthy individuals and can be spread through respiratory droplets.

Pneumococcal infections are more common in young children, older adults, and individuals with weakened immune systems.

Symptoms of pneumococcal infections can include fever, cough, difficulty breathing, and chest pain.

Pneumonia caused by pneumococcus can range from mild to severe, with severe cases potentially leading to hospitalization and death.

Pneumococcal meningitis is a serious infection of the lining of the brain and spinal cord that can lead to permanent brain damage or death.

Pneumococcal sepsis, also known as blood poisoning, is a serious systemic infection that can lead to organ failure and death.

Pneumococcus is responsible for a significant amount of morbidity and mortality worldwide, especially in developing countries.

Vaccines are available to prevent pneumococcal infections, including the pneumococcal conjugate vaccine (PCV) and the pneumococcal polysaccharide vaccine (PPSV).

Antibiotics are used to treat pneumococcal infections, but the bacteria can develop resistance to some antibiotics, making treatment more difficult.

Pneumococcal resistance to antibiotics has become a major public health concern in recent years.
