Three warnings about Natural Rubber Latex Allergy harm:

  1. Latex allergy results directly from repeated exposure to natural rubber latex, and generally worsens progressively with additional exposures to natural rubber latex.
  2. After one develops “Type IV” allergy, the dermatitis caused by a “Type IV” reaction can, with repeated exposure to natural rubber latex, contribute to the development of the more severe and life-threatening “Type I” latex allergy. Having both “Type IV” and “Type I” natural rubber latex allergy is both possible and worse than either type of latex allergy alone.
  3. After you are sensitized to latex, you have latex allergy, and the safest way to minimize/prevent increasingly worsening natural rubber allergic symptoms is to avoid all exposure to natural rubber latex.

It is estimated that 8-12 percent of health care workers are latex sensitive with reactions ranging from irritant contact dermatitis and allergic contact sensitivity, to immediate, possibly life-threatening, sensitivity.
