Which disease is transmitted through birds and bird droppings?

Psittacosis, also known as parrot fever, is a disease caused by the bacterium Chlamydia psittaci, which is commonly found in birds, particularly parrots, pigeons, and other pet birds. Humans can become infected through inhalation of dust from dried bird droppings or respiratory secretions, which can result in a range of symptoms including fever, chills, and respiratory issues.

This disease is specifically associated with birds, making it distinct from the other conditions listed. For example, dengue fever is primarily transmitted by mosquitoes, and tularemia is caused by bacteria found in various animal species, including rodents, rather than birds. Hantavirus is linked to rodents and their droppings, while murine typhus is spread by fleas associated with rats, not birds. Understanding the transmission pathways for each disease highlights why psittacosis is the correct answer in the context of bird-related transmission.
