Which diseases are associated with pigeon droppings?

The association of pigeon droppings with diseases such as cryptococcosis and psittacosis is well-documented in public health.

Cryptococcosis is caused by the fungus Cryptococcus neoformans, which can be found in environments contaminated with pigeon droppings. This fungus is particularly concerning for individuals with weakened immune systems, as it can lead to severe respiratory infections and disseminated disease.

Psittacosis, also known as parrot fever, is caused by the bacterium Chlamydia psittaci, which can be transmitted through inhalation of dust contaminated with the droppings of infected birds, including pigeons. This can result in flu-like symptoms and, in severe cases, pneumonia.

Understanding these associations is critical for pest management professionals, particularly in urban settings where pigeons congregate and where there is a potential risk for exposure to these pathogens through their droppings.
