Legionellosis is an infection caused by the Legionella pneumophila bacterium. There are two forms of legionellosis: Pontiac fever and Legionnaires' disease, which is the more severe of the two infections. Symptoms of Pontiac fever include fever, headache, muscle aches, and chills. Symptoms of Legionnaires' disease include cough, chills, fever and sometimes muscle aches, headaches, loss of appetite, diarrhea, and severe pneumonia. While Pontiac fever resolves on its own, Legionnaires' disease must be treated with antibiotics.
Pneumonia is inflammation of one or both lungs with consolidation. Pneumonia is frequently but not always due to infection. The infection may be bacterial, viral, fungal or parasitic. Symptoms may include fever, chills, cough with sputum production, chest pain, and shortness of breath.
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
Diarrhea is a change is the frequency and looseness of bowel movements. Cramping, abdominal pain, and the sensation of rectal urgency are all symptoms of diarrhea. Absorbents and anti-motility medications are used to treat diarrhea.
Chronic cough is a cough that does not go away and is generally a symptom of another disorder such as asthma, allergic rhinitis, sinus infection, cigarette smoking, GERD, postnasal drip, bronchitis, pneumonia, medications, and less frequently tumors or other lung disease. Treatment of chronic cough is dependant upon the cause.
Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fever is part of the body's own disease-fighting arsenal: rising body temperatures apparently are capable of killing off many disease- producing organisms.
Acute respiratory distress syndrome (ARDS) is a lung condition in which trauma to the lungs leads to inflammation of the lungs, accumulation of fluid in the alveolar air sacs, low blood oxygen, and respiratory distress. Causes of ARDS include: pneumonia, aspiration, severe blow to the chest, sepsis, severe injury with shock, drug overdose, and/or inflamed pancreas. Treatment for ARDS include extra oxygen, and/or medication.
