Pontiac fever is a mild form of Legionellosis, an infection caused by the Legionella bacteria. Unlike Legionnaires' disease, another form of Legionellosis, Pontiac fever does not cause pneumonia.

Symptoms

The symptoms of Pontiac fever include fever, chills, headache, and muscle aches. These symptoms usually begin within a few hours to two days after exposure to the bacteria and last for two to five days.

Cause

Pontiac fever is caused by the Legionella bacteria, which are found naturally in the environment, usually in water. The bacteria grow best in warm water, like the kind found in hot tubs, cooling towers, hot water tanks, large plumbing systems, or parts of the air-conditioning systems of large buildings.

Diagnosis

Pontiac fever is diagnosed based on the patient's symptoms and their exposure to a possible source of Legionella bacteria. Because the symptoms of Pontiac fever are similar to those of other respiratory illnesses, it can be difficult to diagnose.

Treatment

Pontiac fever usually clears up on its own without treatment. However, if symptoms persist, a doctor may prescribe antibiotics.

Prevention

Prevention of Pontiac fever involves controlling the growth of Legionella bacteria in water systems.
