Mycoplasma pneumoniae
Mycoplasma pneumoniae is a common type of lung infection, often called "walking pneumonia" because it tends to be milder than other forms of pneumonia. Children with this infection might not feel sick enough to stay in bed, but they can still have a persistent cough and other respiratory symptoms. It can affect the upper and lower respiratory tracts.
Common symptoms
- Persistent dry cough (can last for weeks or months)
- Sore throat
- Headache
- Low-grade fever
- Fatigue
- Chest pain (less common)
- Wheezing (especially in younger children)
- Earaches (less common)
Cause
This illness is caused by a type of bacteria called Mycoplasma pneumoniae.
How common is it?
Mycoplasma pneumoniae causes up to 20% of community-acquired pneumonia cases in children, particularly those ages 5-14. Also known as "walking pneumonia," it typically causes milder illness but can still lead to missed school days. Outbreaks often occur in schools and dormitories.
Treatment
Mycoplasma pneumoniae is treated with specific antibiotics prescribed by a doctor. It's important for your child to complete the entire course of antibiotics, even if they start feeling better, to ensure the infection is fully cleared. Rest and plenty of fluids also help with recovery.
Prevention
To prevent the spread of Mycoplasma pneumoniae, encourage frequent handwashing with soap and water, especially after coughing or sneezing. Teach your child to cover their mouth and nose with a tissue or their elbow when they cough or sneeze. Avoid close contact with people who are sick, and keep your child home from school or daycare when they are ill to prevent infecting others.
