Doctors play a critical role in the early recognition and reporting of occupational diseases. Singapore, like most countries, imposes a statutory requirement for the mandatory reporting of occupational diseases where the responsibility for notification to the Ministry of Manpower (MOM) rests with the employer and the physician who makes the diagnosis of an occupational disease. The list of 31 reportable occupational diseases is prescribed in the Workplace Safety and Health Act. A robust reporting system enables Singapore to identify and monitor persons at high risk so as to prevent occupational diseases. Timely reporting will also facilitate the compensation of workers with occupational diseases under the work Injury Compensation Act.
