Mycoplasma pneumonia

Print-Friendly  

Mycoplasma pneumonia is an infection of the lungs by the bacteria Mycoplasma pneumoniae (M. pneumoniae).

This type of pneumonia is also called atypical pneumonia because the symptoms are different from those of pneumonia due to other common bacteria.

Mycoplasma pneumonia usually affects people younger than 40.

People who live or work in crowded areas such as schools and homeless shelters have a high chance of getting this condition. But many people who get sick with it have no known risk factors.

I Would Like to Learn About:

  • Causes

    Mycoplasma pneumonia usually affects people younger than 40.

    People who live or work in crowded areas such as schools and homeless shelters have a high chance of getting this condition. But many people who get sick with it have no known risk factors.

  • Symptoms

    Symptoms are often mild and appear over 1 to 3 weeks. They may become more severe in some people.

    Common symptoms include any of the following:

    • Chest pain
    • Chills
    • Cough, usually dry and not bloody
    • Excessive sweating
    • Fever (may be high)
    • Headache
    • Sore throat

    Less common symptoms include:

    • Ear pain
    • Eye pain or soreness
    • Muscle aches and joint stiffness
    • Neck lump
    • Rapid breathing
    • Skin lesions or rash
  • Exams and Tests

    Persons with suspected pneumonia should have a complete medical evaluation. It may be hard for your health care provider to tell whether you have pneumonia, bronchitis, or another respiratory infection, so you may need a chest x-ray.

    Depending on how severe your symptoms are, other tests may be done, including:

    • Complete blood count (CBC)
    • Blood cultures
    • Blood tests
    • Bronchoscopy
    • CT scan of the chest
    • Open lung biopsy (only done in very serious illnesses when the diagnosis cannot be made from other sources)
    • Sputum culture to check for mycoplasma bacteria
  • Treatment

    To feel better, you can take these self-care measures at home:

    • Control your fever with aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs, such as ibuprofen or naproxen), or acetaminophen. DO NOT give aspirin to children.
    • Do not take cough medicines without first talking to your doctor. Cough medicines may make it harder for your body to cough up the extra sputum.
    • Drink plenty of fluids to help loosen secretions and bring up phlegm.
    • Get a lot of rest. Have someone else do household chores.

    Antibiotics are used to treat atypical pneumonia:

    • You may be able to take antibiotics by mouth at home.
    • If your condition is severe, you will likely be admitted to a hospital. There, you will be given antibiotics through a vein (intravenously), as well as oxygen.
    • Antibiotics are used for 2 weeks or more.
    • Finish all the antibiotics you've been prescribed, even if you feel better. If you stop the medicine too soon, the pneumonia can return and may be harder to treat.
  • Outlook (Prognosis)

    Most people recover completely without antibiotics, although antibiotics may speed recovery. In untreated adults, cough and weakness can last for up to a month. The disease can be more serious in the elderly and in those with a weakened immune system.

  • Possible Complications

    • Ear infections
    • Hemolytic anemia
    • Severe pneumonia
    • Skin rashes
  • When to Contact a Medical Professional

    Call for an appointment with your doctor if you develop a fever, cough, or shortness of breath. Although there are numerous causes for these symptoms, you will need to be checked for pneumonia.

    Also, call if you have been diagnosed with this type of pneumonia and your symptoms become worse.

  • Prevention

    Wash your hands often, and have other people around you do the same.

    If your immune system is weak, stay away from crowds. Ask visitors who have a cold to wear a mask.

    Do not smoke. If you do, get help to quit.

    Get a flu shot every year. Ask your doctor if you need a pneumonia vaccine.
