We have not found the delta variant in the community so far. Says Professor Nilika Malavige in a tweet message. She states that the latest sequencing data is available to prove the point.
Hence she says the story in Australian news about the delta introduced to Melbourne by a Sri Lankan isn’t true. It was a transit passenger from elsewhere.
Meanwhile, Dr Chandima Jeewandara gives below their sequencing report as of 09.06.2021
B.1.1.7 (alpha) 80 persons identified from multiple locations
B.1.617.2 (delta): one person from a quarantine facility
B.1.411 (one): SL Lineage from Thissamaharama
B.1.1.7 (alpha) Health care workers who were fully vaccinated: fully recovered
