Pneumonia that is caused by the bacteria Streptococcus pneumoniae, also known as strep or S. pneumoniae, is dangerous among the elderly, where severe cases may result in fatalities, as reported by the United States National Institute of Allergy and Infectious Diseases. Strep pneumonia is the most prevalent type of bacterial pneumonia in adults, as stated by the American Lung Association.
S. pneumoniae is also referred to as pneumococcus. This bacterium attacks the upper respiratory passages of a person, commonly occurring in young children aged 5 and below and among older people aged 65 or above.
Old age is one of the contributing factors that weakens an individual's natural resistance to foreign invaders, including bacteria, hence, an elderly person is more prone to contract the disease. Symptoms may include retching, dizziness, fatigue, headache, fever, abdominal discomfort and other respiratory problems. Preventative measures include getting a pneumococcal vaccine.
