Psittacosis is an infection caused by Chlamydophila psittaci, a type of bacteria found in the droppings of birds. Birds spread the infection to humans. Pet birds (parakeets, parrots and love birds) are the most common birds infected, but other birds such as poultry, pigeons, canaries and sea birds may also be infected. Birds infected may appear healthy or sick. Humans become infected when they inhale bacteria found in dried bird droppings, feather dust or other secretions of infected birds. Symptoms appear one to four weeks after exposure and include fever, chills, headache, cough and muscle aches. Infection is treated with antibiotics.
