Which of the following is a common symptom of pneumonia?

A common symptom of pneumonia is the production of green mucous. When pneumonia occurs, the lung tissue becomes inflamed and produces excess mucus as a response to the infection. This mucus can be indicative of a bacterial infection, where the body's immune response leads to the accumulation of pus and dead cells, resulting in discolored sputum, often appearing green or yellow.

The presence of green mucous can assist healthcare providers in determining the potential etiology of the pneumonia and may influence treatment decisions, such as considering the likelihood of a bacterial rather than a viral infection. Other symptoms typically associated with pneumonia include cough, fever, difficulty breathing, and chest pain, but the green mucous specifically points to the mucosal response characteristic of this respiratory condition.
