Two of three mosques that were closed for cleaning yesterday after being visited by Covid-19 positive patients will reopen today.

Temenggong Daeng Ibrahim Mosque in Telok Blangah and En-Naeem Mosque in Hougang will reopen for noon prayers and thereafter.

Meanwhile, Ahmad Mosque in Pasir Panjang will reopen for prayers tomorrow.

The Islamic Religious Council of Singapore (Muis) said yesterday that it was informed by the Ministry of Health (MOH) that individuals who had tested positive for Covid-19 had been to the three mosques recently.

Bookings for congregational prayer at the mosques yesterday were voided due to the closures.

Muis noted that MOH is actively conducting contact tracing and all congregants who have been identified as close contacts of the individuals who tested positive will be reached for "necessary follow-up action".

"This is also a timely reminder of the importance of using TraceTogether when visiting the mosques, so that anyone who has had possible exposure to an infected person can be identified and reached quickly," said Muis.

Since Nov 13, 10 mosques have been allowing 150 worshippers at each Friday prayer session in a pilot programme, 50 more than the previous limit. Other mosques, including the three that were closed, may have 100.

Muis said last month that it aims to eventually lift the limit for the 10 mosques to 250 people at each session by the end of the year.

This is in line with the Government's move for a pilot programme allowing worship sessions of up to 250 participants for religious organisations that have safely conducted services for 100 people.

The three mosques were closed following announcements by MOH on Tuesday that there were five unlinked cases of Covid-19 in the past week.

The most recent, also announced on Tuesday, was a 66-year-old cleaner who works in the transit area of Changi Airport Terminal 3.

On Monday, MOH announced that a 35-year-old Nepalese man had tested positive in a pre-departure screening on Nov 28 before a trip to the United States.

Two other cases were picked up during community surveillance testing in which 876 stallholders and workers in and near Tekka Centre were tested on Nov 26.

One was a 60-year-old woman who sells mutton at the market.

The other was a 41-year-old work permit holder who is employed as a warehouse assistant.

The last of the five unlinked cases in the past week was a 32-year-old service engineer.

Prior to that, the last infected person in the community was announced on Nov 10.
