Hymenoptera stings among the people who are forestry workers. For them, it acts as an occupational trigger but it has not yet been well defined which is the real incidence of anaphylaxis in these workers, not even in Italy. Two Italian studies reported on the risk of HS in northern Italy and central Italy FW while no data is available on the prevalence in southern Italy ones.
A population of 341 SI FW, was investigated submitting a standardized questionnaire dealing with reactions to Hymenoptera stings, such as large local reactions and systemic reactions.
HS occurred in 203 FW and caused reactions in 77; LLR occurred in 46 and SR in 31; SR was life-threatening in 9/341 FW and was treated with epinephrine at the emergency unit as workers did not carry an epinephrine auto-injector. ASR at a subsequent HS followed an LLR in 21/46 FW.
The study concluded through its findings that the FW in SI has a generic risk of HS anaphylaxis as in the general population but a higher risk of SR and LLR with respect to forestry populations from different Italian geographical areas.
