Atypical pneumonia is a type of pneumonia that is caused by bacteria other than the more common causes of pneumonia, such as Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae. This type of pneumonia is often referred to as “walking pneumonia” because it is usually milder than other types of pneumonia and can be treated without hospitalization.
Atypical pneumonia is usually caused by the bacteria Chlamydia pneumoniae, Legionella pneumophila, or Mycoplasma pneumoniae. It is spread through contact with respiratory secretions, such as saliva, sputum, or mucus. Symptoms of atypical pneumonia can include a dry cough, fatigue, fever, headache, muscle aches, and chest pain. Treatment usually consists of antibiotics, such as erythromycin or tetracycline, and supportive care, such as rest and fluids.
Atypical pneumonia can be prevented by avoiding contact with people who have the infection, washing hands frequently, and avoiding close contact with people who have a weakened immune system or are more likely to get infections. Vaccines are available for some types of atypical pneumonia, such as those caused by Pneumococcus, Haemophilus influenzae, and Mycoplasma pneumoniae. It is important to get vaccinated and to practice good hygiene to help prevent the spread of atypical pneumonia.
