Is Walking Pneumonia Contagious? The Science-based Fact

Imagine feeling a persistent cough, a mild fever, and fatigue, but still managing to continue your day as usual. This is a reality of several individuals living with walking pneumonia- a type of mild pneumonia (also known as Mycoplasma pneumoniae infection) that affects the lungs. Though it seems like a mild infection, it can increase the concern regarding its contagiousness. So, if you or someone around you is struggling with illness, there might arise a question, “Is walking pneumonia contagious?”

This article will answer your question and help know how and for how long this infection is contagious. Additionally, we’ll discuss what you can do to prevent its transmission. Read on!

Is Walking Pneumonia Contagious? 

Yes, according to the American Lung Association, walking pneumonia or mycoplasma pneumoniae infection is contagious, spreading from one individual to another.

Around 2 million people in the United States are affected by this infection every year. The cases among children were high in 2024. However, it does not easily spread compared to other types of pneumonia. This mild infection is typically caused by bacteria- “Mycoplasma pneumoniae” and is spread via respiratory droplets when sneezing, coughing, or talking.

Moreover, it can also be transmitted by bacteria present on the surface contaminated with the infection. The bacteria pass to another person by touching that surface and then your nose, eyes, or mouth. This type of illness commonly spreads in close settings such as workplaces, houses, or schools. 

How Long Is Walking Pneumonia Contagious?

A person can spread the walking pneumonia to others for nearly 10-14 days. This period starts a few days before any potential symptoms develop and lasts till those symptoms may not resolve. Moreover, people can spread this infection even though they do not develop any symptoms or have mild symptoms. This means individuals can still spread walking pneumonia before they get sick. 

How You Get Affected With Walking Pneumonia?

This is how you get infected with walking pneumonia:

• Bacterial infection: The bacteria called Mycoplasma pneumoniae can cause it.

• Close contact: Spread via respiratory droplets when the person with the infection sneezes or coughs.

• Crowded places: Close-setting places like workplaces, houses, or schools can increase the risk of transmission.

• Increased risk of weak immune system: Individuals with weak immune systems are extremely prone to this infection.

• Direct contact: Touching the surfaces contaminated with bacteria like mycoplasma pneumoniae or viruses and then your face can also raise the transmission risk. 

Who is Most Affected by Walking Pneumonia?

Anyone can get affected with walking pneumonia. However, the risk is higher if you:

• are above 2 years

• are around 65 or older

• have asthma

• have emphysema (chronic lung disease)

• are living with chronic obstructive pulmonary disease.

• have a weak immune system or take immunosuppressant drugs

• work or live in crowded settings, including schools, nursing homes, offices, dormitories, or military barracks

• use tobacco products

• use inhaled corticosteroids regularly

Tips To Prevent Walking Pneumonia

Unfortunately, no vaccines are available to prevent the risk of walking pneumonia. However, you can consider these steps to reduce any possibility:

• Cover your mouth and nose: Always use a tissue to cover your nose or mouth or an elbow while sneezing or coughing.

• Regularly wash your hands: Clean your hands using soap and water or alcohol-based hand sanitizer to reduce the risk of spread of respiratory droplets to others via contact.

• Disinfect surfaces: Always disinfect commonly used or touched surfaces or tools such as phones, doorknobs, or light switches.

• Stay home: If you’re diagnosed with this infection, stay home until you completely feel better.

• Avoid smoking: Don’t smoke as it can worsen the symptoms and cause further complications.

• Shortness of breath

• Persistent high fever above 102°F for several days

• Continuous and sharp chest pain.

• Severe fatigue while performing daily activities

By examining the developed symptoms and how long a person had them, healthcare professionals can determine the treatment. 

What Happens if Walking Pneumonia is Left Untreated?

If you leave walking pneumonia untreated, it can lead to a more severe form of pneumonia. This can result in:

• Worsening of symptoms like cough or fatigue

• Spread of infection to lungs or other body parts

• Feeling of exhaustion and weakness for a longer period

• Respiratory complications such as lung damage or difficulty breathing

• Prolonged infection, causing more discomfort

• Possible hospitalization in severe cases
