1.     Introduction
Streptococcus pneumoniae (S. pneumoniae) bacterium are the primary cause of Pneumococcal Disease and is also identified as pneumococcus. Contagions can consequence in pneumonia, contagion of the blood (bacteremia/sepsis), middle-ear infection (otitis media), or bacterial meningitis. According to the World Health Organization (WHO) pneumococcal disease is the vaccine-preventable cause of death among infants and children below 5 years of age. Primarily there are two types of pneumococcal diseases.
1.1.                     Non-invasive pneumococcal diseases
This is less severe than invasive pneumococcal disease and occurs mostly outside of the major organs or the blood. S. pneumoniae can spread from the nasopharynx (nose and throat) to the upper and lower respiratory tract and can exhibit Otitis media - central ear infection. Irritation of the central ear, characteristically with accretion of liquid in the central ear, swelling of the membrane, earache. If the membrane is punctured drainage of pus into the ear canal. Non-bacteremia pneumonia - contagion of the lower respiratory tract without detectable range of organisms to the blood crick
1.2.                     Invasive pneumococcal diseases (IPD)
This type of disease is serious one and occurs inside the major organ or in the blood Such as.
Bacteremia (sepsis) - bacterial contagion of the blood meaning the presence of live bacteria in the blood. , sepsis refers to  blood infection that is related to capillary leak, shock and increased risk of mortality. Meningitis - swelling of the meninges. Meninges are the three membranes which cover the brain and the spinal cord. Bacteremia pneumonia - swelling of one or both lungs.
2.     Pneumococcal Disease Problem
According to WHO around 1.6 million people die each year globally as a result of pneumococcal diseases among them half are children younger than 5 years of age particularly in developing countries. So WHO has classed pneumococcal disease as a major cause of mortality and morbidity?
Pneumococcal pneumonia has a tendency to affect humans when they are very young or very old. Vaccination is the only available tool to prevent pneumococcal disease as per WHO. WHO enhances that “the recent development of widespread microbial resistance to crucial antibiotics emphasizes the crucial need for more effective pneumococcal vaccines?”
3.            Who is at Danger of Pneumococcal Disease?
Anyone can get pneumococcal sickness. Be that as it may, a few gatherings are at an altogether higher hazard for pneumococcal infection or its difficulties.
3.1.         People at higher hazard include:
3.1.1.     Infants and kids more youthful than two years old.
3.1.2.     Children who have a basic medicinal condition which inclines them to obtrusive pneumococcal sickness.
3.1.3.     People more than 65 years old.
3.1.4.     Children in poor zones of creating nations.
3.1.5.     People with debilitated invulnerable frameworks, for example, those with immunosuppression (e.g. high-measurements steroids, chemotherapy), HIV, or AIDS.
3.1.6.     Patients with perpetual illnesses, for example,
Diabetes, Lung sickness, Heart illness, Cancer, Kidney ailment, Sickle cell infection and Alcoholism
3.1.7.     Residents of perpetual (long haul) mind offices.
3.1.8.     Patients who have a past filled with spleen brokenness or spleen illness.
3.1.9.     Tobacco smokers.
3.1.10.   People who have a cochlear embed (a sort of amplifier).
3.1.11.   Patients with cerebrospinal liquid break (e.g. because of broke base of skull)
4. Signs and Symptoms of Pneumococcal Disease
Signs and manifestations of pneumococcal contamination rely on upon the kind of disease the patient has.
A manifestation is something the patient feels, while a sign is something other individuals, for example, the specialist or relatives see. A case of a side effect might be a migraine, and a case of a sign may be a rash.
The signs and side effects of pneumococcal ailment might be non-particular.
4.1.         The most normal signs and indications include:
4.1.1An hoisted body temperature (fever), Chills, Sweat. A throbbing painfulness, Headache and Malaise (for the most part feeling unwell)
4.2. Pneumococcal bacteremia - signs and side effects of may include:
4.2.1.     An hoisted body temperature (fever), Headache, Muscular a throbbing painfulness, Rapid heart rate and Rapid relaxing
4.3. Pneumococcal meningitis - signs and side effects of may include:
4.3.1.     An hoisted body temperature (fever), Headache, Nausea, Vomiting, Sleepiness, Irritability, Stiff neck, Seizures and Sometimes trance like state
4.4. Pneumococcal pneumonia - signs and side effects of may include:
4.4.1.     Cough, A hoisted body temperature (fever), Breathing issues, for example, shortness of breath (quick breathing), Chest torment,
5. Different side effects may include:
5.1Nausea, Vomiting, Headache, Fatigue (tiredness) and Muscle hurts
6. Pneumococcal intense otitis media - signs and side effects of may include:

6.1 Earache, A lifted body temperature (fever), Vomiting, Diarrhea, Temporary hearing misfortune and Ear release
