Although allergic contact dermatitis caused by dust mask straps has been reported, component analysis of the straps is rare. We encountered an outbreak of dermatitis cases due to rubber straps of a DS2 mask (Mask A) at our hospital.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To investigate the cause of dermatitis associated with Mask A rubber strap, identify the allergens responsible for allergic contact dermatitis and propose suitable alternative masks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients\/Methods<\/jats:title>\n                    <jats:p>Twelve healthcare workers who developed contact dermatitis after wearing Mask A were enrolled.
