Bird Diseases and Risk of Bird Droppings
Birds and their droppings can carry a variety of diseases that pose health risks to humans, especially those who work closely with animals or in environments with heavy bird activity. Exposure to droppings may lead to infections such as histoplasmosis, psittacosis, and avian influenza (including H5N1). These illnesses can spread through inhalation of contaminated dust or direct contact with droppings. Practicing good hygiene, using protective gear, and ensuring proper cleanup and ventilation in affected areas can greatly reduce the risk of infection.
