Psittacosis is zoonotic and commonly linked to parrots and other birds, and can present with pneumonia and high fever in humans. This disease is known as:

• A. Parrot fever
• B. Bird flu
• C. Ringworm
• D. Leptospirosis

Answer: (A)

Parrot fever is the classic name for psittacosis, a zoonotic infection transmitted from birds (especially parrots and other pet birds) to humans. It often presents like pneumonia with high fever, which matches the description given. The other terms refer to different diseases: bird flu is avian influenza, a viral respiratory illness; ringworm is a fungal skin infection; leptospirosis is a bacterial disease from animal urine-contaminated water. So parrot fever best fits psittacosis because it directly reflects the bird-associated zoonotic illness described.
