Health director-general Datuk Dr Noor Hisham Abdullah said among the reasons why the 3,000 people had not been screened were that those who had gone abroad had not returned since attending the gathering.
"Maybe, some have still not returned, some may have gone abroad, for example to Sulawesi and India. They left for 40 days and have not returned.
"We are still monitoring and we have the records. It is hoped that when they return they will be screened and quarantined for 14 days," he told a COVID-19 daily media conference here today.
Dr Noor Hisham said 19,032 participants of the gathering at the Sri Petaling Jamek Mosque had been screened thus far with 15,970 samples taken.
‘’There are 1,465 positive cases among the Sri Petaling Jamek Mosque worshippers. There are 10,213 negative cases and 4,292 pending cases. About 3,000 people have yet to be screened,’’ he said.
Dr Noor Hisham said Selangor recorded a high number of cases and the sources were the tahfiz and madrasah (Islamic schools) some whom had attended the tabligh gathering at the Sri Petaling Jamek Mosque.
He said one of the reasons why Selangor had the highest positive cases was because 50 per cent of the cases were linked to the worshippers who had gathered at the Sri Petaling Jamek Mosque, and now it had spread to the Islamic schools.
‘’So, now we see Hulu Langat has 300 positive cases to date. There are about 600 cases in Selangor and half of the cases came from Hulu Langat,’’ he said.
The number of cases in Hulu Langat had gone up to 300 cases from 287 cases previously. There are 90 cases in Kampung Sungai Lui including 25 cases which are linked to the worshippers at the Sri Petaling Jamek Mosque and close contacts (65 cases).
As of today, Dr Noor Hisham said 18 positive COVID-19 cases were detected at the One City Plaza Tower.
As such, he recommended a community enforcement in every housing area to ensure localised cleanliness to check the spread of COVID-19.
"We can enhance it further and on the other hand we are looking closely at hotspot areas. If there is an increase of 10, 20 or even 40 cases within a day, that is a sign for us to come in and enhance the Movement Control Order (MCO) in that area,’’ he said.
