80-90% of pneumonia derives from infections caused by either viruses or bacteria. The cause of bacteria pneumonia is Streptococcus pneumoniae, also known in a shorter term as pneumococcus. The bacteria are responsible for pneumonia illness, also capable of producing the invasive pneumococcal infections (a.k.a. invasive pneumococcal disease - IPD).

The signs and symptoms determine the cause of pneumonia, which determines what kind of treatments should be performed. How serious pneumonia is depends on the clinical characteristics which are either acute or chronic. Infected people often give physical signs, which include a clammy skin, hard time breathing, or face turning pale. The appropriate treatment depends on risk factor of age which begets severe in younger ages, the types of pneumonia, and the person's underlying health, respectively.

Primary symptoms may include fever (sometimes as high as 104 degrees Fahrenheit), cough with sputum production, shaking chills, and difficulty in breathing. Close caption on chest movement and breathing can help diagnose the signs of pneumonia.

The resolution can be completed according to the causative actions or through antibiotics means. However, the pneumococcus has become more resistance against antibiotics. Most cases of pneumonia can be treated without hospitalization since the nature of human body can nullify the illness. Treatment of pneumonia should never be overlooked due to the weakness it causes to the body's immune system and the multiplication of microorganisms causing pneumonia.

The cause of a single type of bacteria; pneumococci bacteria alone can cause various symptoms with pneumonia being the most common of all. Bacteremia in clinical presentation includes: the sinusitis, the otitis, or blood infection causing damage to the brain; meningitis. Typical sepsis and sinusitis is also known as IPD.

IPD is an abbreviation for "Invasive Pheumococcal Disease". The infection can cause a sepsis or having bacterium infection through blood stream and produce toxin compound. Infection in blood stream eventually leads to damage of internal organs. Especially in young child, the sepsis can cause a sudden shock, renal or liver dysfunctional, or stop breathing. A child with meningitis problem may show symptoms such as a shock, tensing, damage to the brain causing liver or heart dysfunctional.

The risk of taking infections occurs in all age groups, and is a leading cause of death among the elderly and young ages out of the weakened immune system factor. Children age under four requires immediate treatment once infected.

Maintain good hygiene in the house and washing your hands often and thoroughly can help reduce your risk since your hands are in most constant contact with germs that can cause pneumonia. Wearing a face mask and always coughing into tissue helps too. Try to keep others from infection by having the one with pneumonia kept separated from anyone with a compromised immune system. Getting vaccinated is also a recommendation.  Pneumonia vaccine is given to prevent one specific type of pneumonia, which is caused by the Pneumococcus. Fortunately, with the discovery of many potent antibiotics, most cases of pneumonia can be successfully treated. In fact, pneumonia can usually be treated with oral antibiotics without the need for hospitalization.
