Exams and Tests
People 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)

In many cases, it is not necessary to make the specific diagnosis before starting treatment.
Treatment
To feel better, you can take these self-care measures at home:
- Control your fever with aspirin, NSAIDs (such as ibuprofen or naproxen), or acetaminophen. DO NOT give aspirin to children because it may cause a dangerous illness called Reye syndrome.

- 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 might be used for 2 weeks or more, although usually fewer days are needed.
- 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 older adults and in those with a weakened immune system.

When to Contact a Medical Professional
Contact your provider if you develop a fever, cough, or shortness of breath. There are many causes for these symptoms. The provider will need to rule out pneumonia.
Also, call if you have been diagnosed with this type of pneumonia and your symptoms become worse after improving first.
Prevention
Wash your hands often, and have other people around you do the same.
Avoid contact with other sick people.
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 provider if you need a pneumonia vaccine.

The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.

Erythema multiforme lesions are circular and may appear in concentric rings (often called target lesions). Target lesions may also be associated with other medical conditions such as herpes infection, streptococcal infection, tuberculosis (TB), or as a reaction to chemicals or medications.

Erythema multiforme lesions are often referred to as target lesions because of the concentric rings the lesions produce. The target appearance is well demonstrated in this photograph.

The red spots on this person's back appear where blisters (bullae) caused by Erythema multiforme have ruptured and the overlying skin removed (denuded). The resulting lesions are yellow-crusted ulcers (erosions). Erythema multiforme may be associated with herpes simplex infection, mycoplasma pneumonia, or other medical conditions such as streptococcal infection, tuberculosis (TB), or may result from exposure to chemicals or medications.
