Helicopters may be partly to blame for disturbing pigeon feces at a Queen Elizabeth University Hospital in Glasgow, Scotland, where two patients died of a fungal infection linked to bird excrement, according to an article on The Times website.
Glasgow’s health board said that helicopters landing on the roof of the hospital had “whisked up” the droppings.
Droppings were later found in the ventilation system connected to wards.
A spokeswoman for the health trust said: “There are a number of hypotheses including the plant room and the helipad. We also contacted other health boards to discuss associated matters.”
