Latin name: Hevea brasiliensis
Source material: Natural rubber from Hevea brasiliensis, without ammonia treatment
The prevalence of latex allergy among health care personnel ranges from 2-25%.
Numerous items, such as latex gloves, catheters, condoms, balloons, sports equipment etc.
Pathways for allergen exposure:
- inhalation of the powder from latex gloves
- direct skin or mucosa (membrane) contact
Latex sensitive patients may react also to some fruits, such as banana, kiwi, avocado, papaya (1-2).
Medical and odontology clinics: Health care personnel, and individuals with a history of repeated surgery (e.g. spina bifida children) are considered a high risk group (3-5).
Latex products for everyday use can be found in almost any environment (6-7).
Confirmed and suspected involvement of cross-reacting allergens in reactions to fruits, vegetables and other plants have been described (1-2).
Cases of anaphylaxis have been reported (9).
