Key facts

  • Community-acquired pneumonia (CAP) is a lung infection picked up in everyday settings rather than in a healthcare facility, ranging from a mild illness managed at home to a serious condition requiring hospital care.
  • Streptococcus pneumoniae is the most commonly identified bacterial cause, though viruses and other bacteria also cause CAP.
  • When a bacterial cause is confirmed or strongly suspected, antibiotics are the cornerstone of treatment; oral agents such as cefdinir are used for mild-to-moderate CAP that can be managed outside hospital.
  • Seek medical attention promptly if breathing becomes laboured, lips or fingertips turn bluish, or symptoms worsen after 48 hours of treatment.

Recognising CAP

Typical signs include a productive cough, fever, chills, and chest pain that worsens on breathing. Shortness of breath and fatigue follow quickly in more severe cases, particularly in older adults or people with other health conditions. A doctor will usually confirm the diagnosis with a chest X-ray and, where needed, a sputum culture to identify the organism involved.

How CAP is treated

When a bacterial pathogen is confirmed or strongly suspected, antibiotics are the cornerstone of treatment. Oral agents such as cefdinir are used for mild-to-moderate CAP in adults and children who can be managed outside hospital. The specific choice and duration of antibiotic depend on local resistance patterns and individual patient factors, including age, other illnesses, and how severe the infection is. More severe cases, or those with risk factors for a poor outcome, are usually treated in hospital, sometimes with intravenous antibiotics initially.

When to see a doctor

Seek medical attention promptly if breathing becomes laboured, lips or fingertips turn bluish, or symptoms worsen after 48 hours of treatment. Anyone with a persistent high fever, confusion, or an existing lung or heart condition should be assessed without delay.
