Pontiac fever, which is caused by Legionella pneumophila, is characterized primarily by a febrile illness that presents with symptoms such as malaise, headache, and muscle aches. This condition is usually self-limiting and does not lead to severe respiratory symptoms or complications that are often associated with other illnesses caused by Legionella, such as Legionnaires' disease.

The symptoms of Pontiac fever typically develop 24 to 48 hours after exposure to the bacteria, which can occur through inhalation of contaminated water droplets. The absence of severe respiratory distress and pneumonia differentiates Pontiac fever from Legionnaires' disease, making the correct symptoms associated with Pontiac fever those outlined in the chosen answer.

In summary, the symptoms of febrile illness, malaise, headache, and muscle aches accurately reflect the clinical presentation of Pontiac fever, distinguishing it from the more severe and acute manifestations of Legionellosis.
