Walking pneumonia is generally treated with antibiotics. Mild infections are often not treated because they tend to clear on their own. With treatment, most people begin to feel better within a few days.
But those that linger on for longer can sometimes turn into walking pneumonia. Walking pneumonia, or atypical pneumonia, is a less serious form of the lung infection pneumonia. It's caused by Mycoplasma bacteria, which causes cold-like symptoms in addition to a low-grade fever and a hacking cough. Most kids with this form of pneumonia will not feel sick enough to stay at home â hence, the name walking pneumonia â and usually will feel well enough to go to school. But even a child who feels fine needs to stay at home for a few days until antibiotic treatment kicks in and symptoms improve.
