Walking pneumonia, also known as atypical pneumonia, is a mild form of pneumonia that is caused by bacteria, viruses, or molds. It is called "walking" pneumonia because the symptoms are usually mild enough that people can continue their daily activities without realizing they have pneumonia. The symptoms of walking pneumonia can resemble those of a cold or flu, and may include a cough, sore throat, headache, mild chills, and a low-grade fever. Other symptoms may include chest pain, labored breathing, and wheezing sounds. Walking pneumonia is contagious and can spread through airborne droplets from close contact, such as coughing, sneezing, or speaking. It is most common in children, especially those ages 5 to 15 years old, and can be brought home by young children who get it at school and then infect family members. Treatment for walking pneumonia usually involves antibiotics and over-the-counter medicines, and most people start to feel better within three to five days. However, a cough from pneumonia can last weeks or months after treatment, and recovery time will vary from person to person. If you have pneumonia symptoms, even if they are mild, you should discuss with your healthcare provider as soon as possible.
