Psittacosis/Ornithosis is primarily spread by which type of animal?

Psittacosis, also known as Ornithosis, is primarily associated with birds, particularly those in the parrot family, including pigeons. This disease is caused by the bacterium Chlamydia psittaci, which is commonly found in the droppings, feathers, and respiratory secretions of infected birds. People can become infected through inhalation of dust contaminated with these materials or by direct handling of the birds.

Pigeons and other birds act as natural reservoirs for this pathogen, making them the primary source of transmission to humans. Awareness of the risk factors associated with handling birds or exposure to their droppings emphasizes the need for precautions such as using protective equipment.

Other animals like bats, shellfish, and rodents have different zoonotic diseases associated with them and do not primarily transmit Psittacosis. This highlights the importance of identifying specific animal sources in understanding disease transmission and implementing effective public health measures.
