SINGAPORE: Seven new cases, including household contacts and family members of previous cases, were on Tuesday (May 11) linked to a cluster of COVID-19 infections at Changi Airport.
A Victoria Junior College student who tested positive last week was also linked on Tuesday to the cluster at the airport, taking the total number of cases in the cluster to 18.
Of the seven new cases, four have tested preliminarily positive for the B1617 variant, which was first detected in India.
The first new case reported on Tuesday is a 63-year-old Singaporean man, known as Case 63059, employed by Ramky Cleantech Services as a cleaner at Changi Airport Terminal 3.

The first infection in the cluster at Changi Airport was detected on May 5, when an 88-year-old man who works as a cleaner at Terminal 3 tested positive.
The Civil Aviation Authority of Singapore (CAAS) and Changi Airport Group (CAG) said on Sunday that all workers in Changi Airport’s operating terminals will be tested for COVID-19 in a special testing operation.
About 9,000 workers from Terminal 1, Terminal 3 and Jewel Changi Airport will undergo these tests. Terminal 2 is not open.
All vaccinated frontline airport workers will also be tested every 14 days as part of rostered routine testing, up from the 28 days previously.
The main cleaning contractor for Changi Airport Terminal 3 has been placed on a “safety time-out” for 14 days since Monday, while the airport’s main security service provider will step up its safe management measures, they said.
Basement 2 of Changi Airport Terminal 3 has been closed temporarily since Monday after several COVID-19 cases visited outlets there, the authorities said.
As of Tuesday, Singapore has reported a total of 61,403 COVID-19 cases and 31 fatalities.
