-tick attaches themselves to bodySlide14
Signs and Symptoms

Do not squeeze the bodySlide16
Allergic reaction to a sting
Can happen almost immediately
Can result in a blockage of airway-> anaphylactic shockSlide17
Signs and Symptoms
Rash, itching
Swollen eyelids, face, or neck tissuesAltered voiceWheezingRespiratory distress
Altered state of consciousSlide18
Management
Follow DRSABCD
Apply pressure immobilisation bandageAsk casualty if they are carrying an EpiPen
-determine whether they can administer EpiPen themselves
4. Ensure casualty keeps still
5. Conscious-> position patient that assists breathingSlide19
Animal Bites
Carry bacteria and other organisms in their mouths
Bites may puncture the skin
