Pneumonia

Pneumonia is a lung infection that causes cough, fever and trouble breathing. It can be serious for some people, but most recover with the right care. Learn about symptoms, causes, treatment and prevention.

Pneumonia is an infection that inflames the air sacs (alveoli) in one or both lungs. These air sacs may fill with fluid or pus, leading to cough, fever, chills and difficulty breathing. Pneumonia can range from mild to severe. While anyone can develop pneumonia, it is most concerning for infants, older adults and people with weakened immune systems.

Common Symptoms

  • Cough, sometimes with phlegm
  • Fever and chills
  • Shortness of breath, during activity or at rest
  • Chest pain that worsens with deep breaths or coughing
  • Fatigue
  • Sweating and clammy skin
  • Loss of appetite
  • Confusion (especially in older adults)

Causes
Pneumonia may be caused by bacteria, viruses, fungi or aspiration (breathing in food, liquid or stomach contents). Examples include:

  • Bacteria: Streptococcus pneumoniae
  • Viruses: influenza, SARS-CoV-2
  • Fungi: mainly in people with weakened immune systems

Risk Factors

  • Age (children under 2 and adults over 65)
  • Weakened immune system (e.g., chemotherapy, immunosuppressive medications)
  • Chronic lung diseases (COPD, asthma)
  • Smoking
  • Recent viral respiratory infection
  • Hospitalization or living in long-term care
  • Difficulty swallowing
  • Chronic conditions such as heart disease or diabetes

How Pneumonia is Diagnosed
Diagnosis includes a review of medical history and a physical exam. Tests may include:

  • Chest X-ray to detect lung inflammation
  • Oxygen level checks using a finger sensor or blood tests
  • Blood work, sputum testing, or PCR tests to identify the infection

Treatment Overview
Treatment depends on the cause and severity:

  • Bacterial pneumonia: antibiotics
  • Viral pneumonia: antiviral medications (if appropriate) and supportive care
  • Fungal pneumonia: antifungal medications
    Supportive care includes rest, fluids, fever management, cough relief and oxygen if needed. Mild pneumonia can often be managed at home, while severe cases may require hospitalization.

Prevention

  • Stay up to date on vaccines (pneumococcal, flu)
  • Practice good hand hygiene
  • Avoid smoking
  • Manage chronic health conditions promptly

If you have symptoms such as trouble breathing, fever with cough, chest pain or confusion, contact TidalHealth promptly. Early evaluation can improve outcomes.

Is pneumonia contagious?
Some types of pneumonia, especially those caused by bacteria or viruses, can spread from person to person through respiratory droplets. Other types, such as fungal or aspiration pneumonia, are not contagious. Practicing good hand hygiene, wearing a mask when you are sick, and staying home while contagious can help reduce the risk of spreading infection.

How can I tell if I have pneumonia or just a cold or bronchitis?
Pneumonia often causes higher fevers, more severe shortness of breath, and chest pain that worsens with breathing. A chest X-ray and a physical exam are usually needed to distinguish pneumonia from a cold, bronchitis, or other respiratory illnesses.

When should I see a doctor or go to the emergency room?
Seek immediate care if you have:

  • Trouble breathing
  • Persistent high fever
  • Chest pain
  • Coughing up blood
  • Severe weakness or confusion
  • Signs of low oxygen (e.g., bluish lips or face)

Contact your healthcare provider promptly if you have a high fever, worsening symptoms, or are in a high-risk group, including young children, older adults, or people with weakened immune systems.

How is pneumonia treated and how long does treatment take?

  • Bacterial pneumonia: Treated with antibiotics; improvement often starts within 48–72 hours, but the full course should be completed.
  • Viral pneumonia: Managed with antiviral medications when available and supportive care.
    Full recovery may take 1–3 weeks or longer depending on age, overall health, and severity of infection.

Do I need antibiotics for pneumonia?
Antibiotics are necessary only for bacterial pneumonia. They do not treat viral pneumonia. Your provider will decide based on symptoms, exam findings, and test results.

Can pneumonia lead to complications?
Yes. Complications may include:

  • Fluid around the lungs (pleural effusion)
  • Lung abscess
  • Sepsis
  • Respiratory failure
    Prompt treatment lowers the risk of complications.

How can I prevent pneumonia?

  • Stay up to date on vaccines (pneumococcal, flu)
  • Practice good hand hygiene
  • Avoid smoking
  • Manage respiratory infections promptly

High-risk individuals may require additional preventive measures, as advised by their healthcare provider.

Will I need follow-up after pneumonia?
Many people benefit from a follow-up visit to ensure symptoms are improving. Repeat chest X-rays may be recommended for older adults, smokers, or when symptoms persist.

Can pneumonia be treated at home?
Mild pneumonia in otherwise healthy individuals can often be managed at home with prescribed treatment, rest, fluids, and regular monitoring. Clear instructions should be given for when to seek further care and follow-up.

Are there special considerations for children or older adults?
Young children and older adults may become sicker more quickly and have higher risk for severe illness. They may require closer observation, faster evaluation, and earlier hospital care. Always consult a pediatrician or geriatric specialist if pneumonia is suspected in these groups.
