An anaphylactic reaction to latex would primarily be caused by what route?

An anaphylactic reaction to latex is primarily caused by the contact route. In this scenario, individuals with latex allergies can have an immediate and severe allergic response when their skin comes into direct contact with latex products, such as gloves or catheters. These products can release proteins that trigger the immune system in susceptible individuals, leading to anaphylaxis.

While inhalation of latex particles from powder contained in gloves or ingestion of latex-containing food products can also cause allergies, these routes are less common in terms of triggering anaphylactic reactions compared to direct skin contact, especially in healthcare settings where latex gloves are frequently used. Therefore, contact is recognized as the primary route for causing anaphylaxis in individuals allergic to latex.
