Common lung infection symptoms include shortness of breath, persistent cough, pain and increased or unusual mucus production, according to WebMD. Symptoms vary depending on the underlying condition; pneumonia and bronchitis are two of the more common lung infections.
Pneumonia may result from bacteria, fungal or viral infections, explains Ohio State University's Wexler Medical Center. Typical symptoms include cough, fever, chills and trouble breathing, according to the American Lung Association. Some patients may also experience loss of appetite, confusion, headache, clammy skin and sharp chest pains. The symptoms of bronchitis are similar to the those of pneumonia, but typically accompanied by a milder fever, if any, states WebMD. Patients are advised to drink plenty of fluids to help loosen secretions and bring up phlegm and get plenty of rest to help restore lost energy.
Tuberculosis is another serious lung disorder and may be latent -non-contagious- or active -easily spread to others. Symptoms of active tuberculosis include unintentional weight loss, night sweats, chills, fatigue and coughing up blood, according to Mayo Clinic. Tuberculosis may also occur in other parts of the body, causing symptoms relative to the organ involved; its presence in the spine may result in back pain, while tuberculosis in the liver may cause blood in the urine.
Persons at an increased risk for tuberculosis include HIV and AIDS patients, IV drug users, those in contact with infected patients and healthcare workers responsible for treating high-risk individuals, explains Mayo Clinic.
