There's a question in UWorld.... a woman experienced hives after using barrrier contraceptive and now after undergoing cholecystectomy, immediately developed hives, rash and hypotension. The answer was Latex allergy.The explanation said she was experiencing anaphylactic shock- hives,rash and hypotension(so this is Type I hypersensitivity right.)Healthcare workers and patients with history of atopy are at increased risk of experiencing latex allergy from condoms or surgical gloves.

wikepedia says latex allergy is both Type I & IV Hypersensitivity.Type I natural rubber latex allergy is caused from IgE (immune) mediated reactions to proteins found in the Hevea brasiliensis tree, a type of rubber tree.Type IV reactions are caused by the chemicals used to process the (synthetic) rubber. Type IV allergies caused by synthetic rubber products are an increasing problem for healthcare workers.
