Mycoplasma pneumonia, often called "walking pneumonia," is a mild bacterial respiratory infection caused by Mycoplasma pneumoniae. Unlike many other bacteria, Mycoplasma pneumoniae lacks a cell wall, making it naturally resistant to antibiotics such as penicillins. The infection commonly affects children, teenagers, and young adults, although people of any age can develop it. Many individuals remain well enough to continue their daily activities despite having pneumonia, which is why it is often referred to as walking pneumonia.

What are the Symptoms of Mycoplasma Pneumonia?

Symptoms usually develop gradually over one to three weeks and may initially resemble those of a common cold before progressing to pneumonia.

Initial Symptoms

Sore throat.
Fatigue.
Headache.
Low-grade fever.

Progressive Symptoms

Persistent cough, usually dry but sometimes productive.
Chest pain, especially when coughing or taking a deep breath.
Shortness of breath.
Increasing fatigue.
Muscle aches.

Severe Symptoms

High fever.
Rapid breathing.
Wheezing.
Cyanosis (bluish discoloration of the lips or skin due to low oxygen).

What Causes Mycoplasma Pneumonia?

Mycoplasma pneumonia is caused by infection with Mycoplasma pneumoniae, which spreads from person to person through respiratory droplets.

Causes

Mycoplasma pneumoniae bacterial infection.
Spread through coughing or sneezing.
Close contact with an infected person.
Transmission in crowded settings such as schools, hostels, dormitories, and offices.

When should you see a doctor for Mycoplasma Pneumonia?

Seek medical attention if respiratory symptoms persist, worsen, or interfere with your daily activities. Early diagnosis and treatment help prevent complications.

You may be treated by a General Physician, Pulmonologist, Pediatrician, or an Infectious Disease Specialist, depending on your age and the severity of the infection.

Fever lasting longer than 3 days.
Cough lasting more than a week or worsening.
Shortness of breath or chest pain.
Severe weakness or persistent fatigue.
Symptoms in children, older adults, or people with chronic medical conditions.
