What causes pneumonia?

Pneumonia can be caused by bacteria (most common: Streptococcus pneumoniae), viruses (influenza, RSV, COVID-19), or fungi. Community-acquired pneumonia is caught outside healthcare settings, while hospital-acquired pneumonia develops 48+ hours after hospital admission and tends to be more serious due to antibiotic-resistant bacteria.

How do I know if I have pneumonia vs. a cold or flu?

Pneumonia symptoms are more severe and persistent than a cold. Key differences: high fever with shaking chills, sharp chest pain that worsens with deep breathing or coughing, shortness of breath even at rest, cough producing thick mucus (green, yellow, or bloody), and extreme fatigue. If symptoms worsen after initial improvement, see a doctor immediately.

Is pneumonia contagious?

Yes, most types of bacterial and viral pneumonia are contagious through respiratory droplets. However, not everyone exposed will develop pneumonia—it depends on the specific pathogen and the person's immune system. Walking pneumonia (caused by Mycoplasma) is less severe but highly contagious.

Who should get the pneumonia vaccine?

CDC recommends pneumococcal vaccines for: all adults 65+, children under 5, people 6-64 with certain chronic conditions (diabetes, heart/lung disease, weakened immune systems), and smokers. There are two types: PCV (Prevnar) and PPSV23 (Pneumovax). Many adults need both vaccines for complete protection.

How is pneumonia treated?

Treatment depends on the cause. Bacterial pneumonia requires antibiotics, viral pneumonia may need antiviral medications, and fungal pneumonia requires antifungal medications. Mild cases can be treated at home with rest, fluids, and fever reducers. Severe cases require hospitalization with IV antibiotics, oxygen therapy, or breathing support.

When is pneumonia a medical emergency?

Seek emergency care for: difficulty breathing or shortness of breath, chest pain, bluish lips or fingernails, confusion or altered mental state, high fever (over 102°F) not responding to medication, coughing up blood, rapid heartbeat, or symptoms in high-risk individuals (infants, elderly, immunocompromised).

¿Qué es Pneumonia?

Pneumonia kills more children worldwide than any other infectious disease. It can be caused by bacteria, viruses, or fungi. While anyone can get pneumonia, it's particularly dangerous for certain groups. Vaccines can prevent some of the most common and dangerous types of pneumonia, making prevention key.

Síntomas

High fever, sweating, and shaking chills
Cough producing phlegm (green, yellow, or bloody)
Sharp or stabbing chest pain (worse with breathing or coughing)
Shortness of breath and rapid breathing
Extreme fatigue and low energy
Nausea, vomiting, or diarrhea
Confusion or changes in mental awareness (especially in elderly)
Lower than normal body temperature (in elderly or immunocompromised)

Transmisión

Pneumonia-causing germs spread through respiratory droplets from coughing or sneezing, touching contaminated surfaces, or aspiration (inhaling food, drink, or saliva into the lungs). Can develop after viral infections like flu or COVID-19.

Período de Contagio: Varies by cause; bacterial pneumonia is contagious while antibiotics haven't taken effect (24-48 hours after starting treatment); viral pneumonia can be contagious for several days to weeks

Prevención

Pneumococcal vaccines (PCV13/PCV15/PCV20 and PPSV23)
Annual flu vaccine (prevents flu-related pneumonia)
COVID-19 vaccination
Hand hygiene (wash frequently with soap and water)
Don't smoke and avoid secondhand smoke
Practice good health habits (adequate sleep, healthy diet, exercise)
Avoid close contact with people who are sick
Clean and disinfect frequently touched surfaces
Manage chronic conditions (diabetes, asthma, heart disease)
