What is a common symptom of pneumonia besides cough?

A common symptom of pneumonia, in addition to a cough, is indeed shortness of breath, chest pain, and fever, which are collectively experienced by many individuals with this respiratory condition.

Shortness of breath occurs because pneumonia impairs the lungs' ability to efficiently exchange oxygen and carbon dioxide, leading to feelings of breathlessness and increased work of breathing. Chest pain may arise due to inflammation of the pleura (the lining around the lungs) or as a result of deep breathing caused by irritation from coughing. Fever is a typical response to infection. When the body identifies the presence of pathogens, such as bacteria or viruses responsible for pneumonia, it mounts an immune response, which can include elevating body temperature.

The choice indicating all of the above is correct as it encompasses the range of symptoms that are commonly associated with pneumonia, illustrating that the condition can manifest in various ways beyond just a cough alone.
