Latex allergy occurs when the body's natural defences against an allergen come into force.
Antibodies are produced by the initial reaction to latex which sensitise the cells in all tissues. The severity of subsequent reactions depends on the means of entry of the antigen. Exposure to latex occurs when products containing rubber come in contact with a person's skin or mucous membranes such as the mouth, eyes, genitals, bladder or rectum. Serious reactions can also occur when latex enters the bloodstream. In addition, the powder from balloons or gloves can absorb particles and become airborne causing reactions when breathed by a latex sensitive person.
