CYBERJAYA, July 4 — The Ministry of Health (MOH) will conduct further examinations to identify the actual cause of Myokymia suffered by student, Irfan Wafiy Idham Wazir, after he was believed to have been exposed to the toxic pollutions of Sungai Kim Kim, Pasir Gudang, in March.

Deputy Minister of Health Dr Lee Boon Chye said that the ministry must determine whether the ailment which caused several parts of the body to tremble was related to the toxic pollution in question.

‘‘There are many possibilities to Myokymia, sometimes it is due to brain tumour or other diseases. So, we must identify what is the cause of the ailment before we make any conclusion.

‘‘We will conduct further investigation and examination whether it is related to the pollution or not,’’ he said when met by reporters after delivering a keynote address at the 2019 Sustainable Development Target Conference here today.
