Walking Pneumonia

Unlike people with typical pneumonia, who may become severely ill, people with walking pneumonia can avoid hospitalization but may have to modify their daily routines and are likely to have some fairly uncomfortable symptoms.
Overview
What Is Walking Pneumonia?
Walking pneumonia, like all forms of pneumonia, is an infection of tiny air sacs in the lungs called alveoli.
When microbes like bacteria invade the lungs, they can infect the alveoli, causing inflammation and swelling in the airways and alveoli.
Signs and Symptoms of Walking Pneumonia
- Sore throat
- Extreme tiredness
- Low-grade fever (less than 101 degrees F)
- Mild chills
- Cough
- Sneezing
- Headache
- Chest pain or discomfort
- Diarrhea
- Wheezing
- Vomiting

Causes of Walking Pneumonia
While walking pneumonia can be caused by bacteria, viruses, or in some instances, mold, most cases are due to a type of bacteria called Mycoplasma pneumoniae (M. pneumoniae).
Viral infections, such influenza, COVID-19, and RSV, can also lead to walking pneumonia.
How Is Walking Pneumonia Different From Regular Pneumonia?
Walking pneumonia and typical pneumonia have different causes. While walking pneumonia is usually linked to Mycoplasma pneumoniae bacteria, typical pneumonia is usually associated with Streptococcus pneumoniae bacteria, Staphylococcus aureus bacteria, and certain viruses (such as those that cause COVID-19 and influenza).
While people with walking pneumonia may experience uncomfortable, cold-like symptoms, those with regular pneumonia might struggle to breathe, have intense coughing fits, see their heart rate shoot up, and spike a fever.
Is Walking Pneumonia Contagious?
Walking pneumonia is very contagious, passing from one person to the next through tiny droplets that enter the air when coughing, sneezing, talking, or breathing.
How Is Walking Pneumonia Diagnosed?
Treatment and Medication Options for Walking Pneumonia
Walking pneumonia often goes away on its own. Patients are advised to get lots of rest, drink plenty of fluids, and take fever-reducing medicine if needed.
Some patients may benefit from a second-line antibiotic regimen (when other treatments aren’t working), such as fluoroquinolones or tetracyclines.
Prevention of Walking Pneumonia
- Wash your hands often, especially after coughing or blowing your nose, going to the bathroom, and diapering, and before eating or preparing foods.
- Cover your mouth with a tissue when you cough or sneeze.
- Don’t smoke or drink alcohol. Smoking and alcohol can inhibit the body’s ability to fight off infection.
- Maintain overall health. Stick with a healthy diet, rest, and get regular exercise.
Are There Vaccines for Walking Pneumonia?
How Long Does Walking Pneumonia Last?
Complications of Walking Pneumonia
Walking pneumonia can occasionally lead to severe and even life-threatening complications, such as:
- Brain and nervous system infections, such as meningitis, myelitis (inflammation of spinal cord), and encephalitis (inflammation of the brain)
- Severe lung damage
- Hemolytic anemia, a condition in which there are not enough red blood cells in the blood because the body is destroying them
- Respiratory failure requiring breathing machine support (ventilator)
When Should You Call Your Doctor?
- A very high fever
- New symptoms, such as an earache, rash, or sore throat
- Coughing that keeps you from resting or causes severe fatigue and chest pain
Questions to Ask Your Doctor
- How can you be sure this is walking pneumonia?
- If it’s not walking pneumonia what else could it be?
- Are antibiotics needed?
- Is it okay to take cough medicine?
- Is it necessary to miss school or work while recuperating?
- What’s the plan if symptoms get worse?
- Is it safe to be around someone with walking pneumonia?
- How can someone not spread walking pneumonia?
- Should I schedule a follow-up appointment?
The Takeaway
- Walking pneumonia most often affects children and teenagers.
- Symptoms are generally mild and usually get better on their own.
- Because walking pneumonia is often a bacterial infection, antibiotics may help.

Michael S. Niederman, MD, is the lead academic and patient quality officer in the division of pulmonary and critical care medicine at Weill Cornell Medical Center in New York City; a professor of clinical medicine at Weill Cornell Medical College; and Lauder Family Professor in Pulmonary and Critical Care Medicine. He was previously the clinical director and associate chief in the division of pulmonary and critical care medicine at Weill Cornell Medical Center.
His focus is on respiratory infections, especially in critically ill patients, with a particular interest in disease pathogenisis, therapy, and ways to improve patient outcomes. His work related to respiratory tract infections includes mechanisms of airway colonization, the management of community- and hospital-acquired pneumonia, the role of guidelines for pneumonia, and the impact of antibiotic resistance on the management and outcomes of respiratory tract infections.
He obtained his medical degree from Boston University School of Medicine, then completed his training in internal medicine at Northwestern University School of Medicine, before undertaking a pulmonary and critical care fellowship at Yale University School of Medicine. Prior to joining Weill Cornell Medicine, he was a professor in the department of medicine at the State University of New York in Stony Brook and the chair of the department of medicine at Winthrop-University Hospital in Mineola, New York, for 16 years.
Dr. Niederman served as co-chair of the committees that created the American Thoracic Society's 1993 and 2001 guidelines for the treatment of community-acquired pneumonia and the 1996 and 2005 committees that wrote guidelines for the treatment of nosocomial pneumonia. He was a member of the American Thoracic Society/Infectious Diseases Society of America committee that published guidelines for community-acquired pneumonia in 2007. He was also the co-lead author of the 2017 guidelines on nosocomial pneumonia, written on behalf of the European Respiratory Society and the European Society of Intensive Care Medicine.
He has published over 400 peer-reviewed or review articles, and has lectured widely, both nationally and internationally. He was editor-in-chief of Clinical Pulmonary Medicine, is an associate editor of Critical Care and the European Respiratory Review, and serves on the editorial boards of Critical Care Medicine and Intensive Care Medicine. He has previously served on the editorial boards of the American Journal of Respiratory and Critical Care Medicine and Chest. For six years, he was a member of the Board of Regents of the American College of Chest Physicians, and in 2013, he was elected as a master of the American College of Physicians.
