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. Read more: Legionnaires' Disease Article

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.
Fever in Adults and Children
Although a fever technically is any body temperature above the normal of 98.6 F (37 C), in practice, a person is usually not considered to have a significant fever until the temperature is above 100.4 F (38 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.
Pneumonia (Symptoms, Causes, Types, Treatment, and Recovery)
Pneumonia is inflammation of the lungs caused by fungi, bacteria, or viruses. Symptoms and signs include cough, fever, shortness of breath, and chills. Antibiotics treat pneumonia, and the choice of the antibiotic depends upon the cause of the infection.

ARDS (Acute Respiratory Distress Syndrome)
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. ARDS can be life-threatening. Signs and symptoms of are shortness of breath and low levels of oxygen in the blood, which can cause your organs to fail. Causes of ARDS include: Pneumonia Aspiration into the lungs Severe blow to the chest Sepsis Severe injury with shock Drug overdose Inflamed pancreas Other lung conditions and infections Burns Sepsis Near drowning Fractures There have been genetic factors linked to ARDS. Treatment for includes supplemental oxygen, and/or medication. According to some studies, survival rates for ARDS depend upon the cause associated with it, but can vary from 48% to 68%.REFERENCES: Harman, EM, MD.

Sick Building Syndrome
Multiple chemical sensitivity (MCS) or also referred to as sick building syndrome or environmental illness is the name given by some to a condition in which various symptoms reportedly appear after a person has been exposed to any of a wide range of chemicals. The exposure may occur as a major event, such as a chemical spill, or from long-term contact with low-levels of chemicals, such as in an office with poor ventilation. As a result of exposure, people with MCS (Si ck Building Syndrome) develop sensitivity and have reactions to the chemicals even at levels most people can tolerate.
