according to a training course i had to take:
44% of people working with lab animals develop allergies to one or more species. this usually happens within the first three years, although the general range is considered to be a little as a month, up to nine years.
80% of these symptoms in allergic individuals are upper respiratory (sneezing, running/itchy nose and eyes), and 20-30% of these are lower respiratory (broncho-constriction/asthma)
the likeliness of developing one of these allergies stems (partially) from atopy which is the tendency to develop some forms of allergies, which is more prevalent in males than females (47% vs 37%)
