Why latex allergy now?

Type I allergy to latex did not appear in the literature until 1979. For over 100 years people have used natural rubber latex products without apparent problems. Why are allergies appearing now? Scientists are not absolutely sure. Reasons may include an unprecedented increase in the use of latex gloves, changes in the manufacturing process by some manufacturers, and the switch to one-time-use disposable gloves. To reduce the risk of latex protein allergy, health care workers should use nonlatex gloves for activities that are not likely to involve contact with infectious materials. Appropriate barrier protection is necessary when handling infectious materials. When using latex gloves, use powder-free gloves with reduced protein content. Sensitized individuals should use only nonlatex gloves.
