Bacterial Pneumonia
Urgent
Bacterial pneumonia is an infection of the lungs caused by bacteria. It can cause inflammation and fluid or pus in the air sacs, making breathing more difficult. Common symptoms include cough, fever, chills, chest discomfort, shortness of breath, fatigue, and sometimes mucus production. Severity varies from mild illness to a potentially serious infection requiring hospitalization.

When to Seek Medical Attention
Bacterial pneumonia requires prompt medical assessment and may require antibiotic treatment. Seek care for persistent fever, worsening cough, chest pain, dehydration, or increasing shortness of breath. Emergency assessment is needed for severe breathing difficulty, bluish lips or skin, confusion, fainting, severe chest pain, coughing up significant blood, or rapidly worsening illness.

Causes 1
Bacterial pneumonia can be caused by several types of bacteria, including Streptococcus pneumoniae and other respiratory pathogens. Bacteria may reach the lungs after inhalation of infected respiratory particles or aspiration of material from the mouth or stomach. Pneumonia can also develop after another respiratory infection or when the immune system is unable to control bacterial growth effectively.
Infection
Risk Factors
Risk is higher in older adults, young children, and people with weakened immune systems or chronic heart, lung, kidney, or metabolic conditions. Smoking, recent respiratory infection, hospitalization, aspiration risk, and close exposure to infected individuals may also increase risk. People living in healthcare or long-term-care settings can have additional exposure to certain bacterial pathogens.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on symptoms, physical examination, and assessment of breathing and vital signs. Chest imaging, usually a chest X-ray, can help identify lung infection. Blood tests and sputum testing may be used in selected cases to identify bacterial infection or assess severity. Additional testing may be needed for people who are severely ill, hospitalized, or at increased risk of complications.
Prevention
Key Prevention Tips
Good hand hygiene, avoiding tobacco smoke, maintaining recommended vaccinations, managing chronic medical conditions, and reducing exposure to respiratory infections can lower pneumonia risk
Staying up to date with recommended pneumococcal and influenza vaccination is particularly important for eligible people
People who are ill should follow appropriate respiratory hygiene and seek care when symptoms become severe
Prevention Guidance
Good hand hygiene, avoiding tobacco smoke, maintaining recommended vaccinations, managing chronic medical conditions, and reducing exposure to respiratory infections can lower pneumonia risk. Staying up to date with recommended pneumococcal and influenza vaccination is particularly important for eligible people. People who are ill should follow appropriate respiratory hygiene and seek care when symptoms become severe.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
