Psittacosis
Psittacosis is a bacterial disease carried by birds and transmitted to humans when they inhale dried secretions from infected birds. Although all birds are susceptible, pet birds (parrots, parakeets, macaws and cockatiels) and poultry (turkeys and ducks) are most frequently involved in transmission to humans. In people, the disease causes fever, chills, headache, muscle aches and a dry cough, and often pneumonia. Complications and even death can occur.
