Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses, and fungi, can cause pneumonia. Several different types of bacteria can cause pneumonia, including streptococcus pneumoniae, legionella pneumophila, mycoplasma pneumoniae, chlamydia pneumoniae, and haemophilus influenzae.

The different viruses that can cause pneumonia include respiratory syncytial virus (RSV), some common cold and flu viruses, and SARS-CoV-2. Fungal pneumonia is more common in people who have chronic health problems or weakened immune systems. Some of the types include pneumocystis pneumonia (PCP), coccidioidomycosis, histoplasmosis, and cryptococcus.

Pneumonia can range in seriousness from mild to life-threatening. It is most serious for infants and young children, people older than age 65, and people with health problems or weakened immune systems.


The symptoms of pneumonia can range from mild to severe and include fever, chills, cough, usually with phlegm, shortness of breath, chest pain when you breathe or cough, nausea, vomiting, and diarrhea. The symptoms can vary for different groups. Newborns and infants may not show any signs of the infection. Others may vomit and have a fever and cough. They might seem sick, with no energy, or be restless. Older adults and people who have serious illnesses or weak immune systems may have fewer and milder symptoms. They may even have a lower than normal temperature. Older adults who have pneumonia sometimes have sudden changes in mental awareness.


Treatment for pneumonia involves curing the infection and preventing complications. People who have community-acquired pneumonia usually can be treated at home with medication. Although most symptoms ease in a few days or weeks, the feeling of tiredness can persist for a month or more.

Specific treatments depend on the type and severity of your pneumonia, your age and your overall health. The options include antibiotics, cough medicine, and fever reducers. Antibiotics are used to treat bacterial pneumonia. It may take time to identify the type of bacteria causing your pneumonia and to choose the best antibiotic to treat it. If your symptoms don’t improve, your doctor may recommend a different antibiotic. Cough medicine may be used to calm your cough so that you can rest. Because coughing helps loosen and move fluid from your lungs, it’s a good idea not to eliminate your cough completely. In addition, you should know that very few studies have looked at whether over-the-counter cough medicines lessen coughing caused by pneumonia. Fever reducers may be used as needed for fever and discomfort. These include drugs such as aspirin, ibuprofen (Advil, Motrin IB, others) and acetaminophen (Tylenol, others).
