Kosmo! reported that 20 orang asli women contracted syphilis after having unprotected sex with foreigners for several months.
The discovery was made by doctors and medical assistants from the Orang Asli Development Department (Jakoa) Hospital in Gombak and the Jerantut Health Department.
A hospital staff said the foreigners worked at Ciku, Gua Musang and Hulu Tembeling.
The women had scabies and lice infestation on their private parts.
"We fear that there are more orang asli women who have syphilis," he said during the "Saya Mahu Sihat" medical aid programme in Jerantut.
Senator Muhammad Olian Abdullah, when told of it, was shocked and asked the Jakoa Hospital and the Jerantut Health Department to take measures to overcome the problem.
