How contagious is walking pneumonia in adults?

Walking pneumonia is a highly contagious disease that is spread through the droplet route, according to WebMD. This means that it is spread through patients coughing or sneezing into the atmosphere. Anyone within a short distance around the patient is at risk for developing the disease.

Walking pneumonia is a common disease that affects both adults and children, states WebMD. It is a nonmedical term that is often used by the general public to describe a case of mild pneumonia. Patients with walking pneumonia are seldom hospitalized and may go to work or school with the disease. These patients are at risk of spreading the disease to their coworkers and close companions.
