- Community-acquired—from the community, such as a school, gym, or at work
- Nosocomial—in a hospital or healthcare setting
- Aspiration—happens when foreign matter is inhaled into the lungs, such as food, liquid, saliva, or vomit
- Infection from specific types of:
- Other specific germs
- Chemical exposure and irritation
|Copyright © Nucleus Medical Media, Inc.|
- Living in crowded living conditions, such as dormitories or nursing homes
- Alcohol use disorder or drug abuse
- Trouble swallowing or coughing
- Having certain lung conditions, such as chronic obstructive pulmonary disease (COPD) or cystic fibrosis
- Allergies or asthma
- Sleep apnea
- Being on a ventilator
- Heart disease
- Weakened immune system
- Exposures to respiratory inhalants at work, such as:
- Vegetable dusts
- Chest pain
- Increased mucus production
- Fever and chills
- Trouble breathing
- Blood tests and/or cultures
- Sputum culture
- Urine tests
- A chest x-ray
- A lung ultrasound
- What caused the pneumonia
- Severity of symptoms
- Other factors, like your overall health
- Antibiotics—for pneumonia caused by bacteria
- Antifungal medications—for pneumonia caused by fungi
- Antiviral medications—for pneumonia caused viruses, such as influenza
- Over-the-counter medications to reduce fever and discomfort
- Vitamin C may be advised if you don't get enough in your diet
- Oxygen therapy may be needed in more severe cases
- Flu vaccine—pneumonia may be a complication of the flu for people at high risk of infection, especially aged 50 years and older
- Pneumococcal vaccine:
- All adults who are aged 65 years or older
- Adults of any age who are at high risk of infection or have a suppressed immune system
- If you smoke, talk to your doctor about how you can successfully quit. Smoke weakens the lungs' resistance to infection and increases recovery time.
- Avoid close contact with people who have the cold or flu.
- Wash your hands often, especially after coming into contact with someone who is sick..
- Protect yourself on jobs that include chemicals or other lung irritants.
- Maintain good control of any chronic disease, such as asthma and diabetes.
