Tick anaphylaxis and allergies

With tick-related conditions on the rise in Australia, knowledge of prevention and treatment strategies is vital

In Australia, tick-induced allergies occur along the entire eastern seaboard and up to 20-30km inland, mirroring the distribution of the Australian paralysis tick, Ixodes holocyclus.

Tick-induced allergies comprise large local reactions to ticks, tick anaphylaxis, and mammalian meat/mammalian meat product allergy and anaphylaxis. While tick anaphylaxis occurs virtually only in Australia, mammalian meat allergy following tick bites has been reported in many tick-endemic countries.1,2

The association between mammalian meat anaphylaxis and prior tick bites was first described in Australia in 2007, which has the highest prevalence of the condition worldwide.2-4

In tick hyper-endemic regions, more adults carry an adrenaline auto-injector for tick-induced mammalian meat allergy (0.12%) than for peanut allergy (0.1%), which is the commonest reason for adults carrying
