USJ Department of Immunology found Omicron variant from a Nigerian Passenger

The report of whole genomic sequencing of the SARS-CoV-2 variants in Sri Lanka was issued on 03.12.2021 by the Allergy, Immunology and Cell Biology Unit of the Department of Immunology Molecular and Molecular Medicine of the University of Sri Jayewardenepura. The study was carried out by USJ researchers including Prof. Neelika Malavige and Dr. Chandima Jeewandara.

94 samples of PCR positive passengers who arrived during the last 2 weeks, and samples from Colombo, Gampaha, Ratnapura, Kalutara, Karapitiya, Trincomalee and Vaviniya districts were sequenced this week. Out of the 94 samples that were sequenced, Omicron was detected from a Nigerian passenger. All other samples were of the delta variant.

Detection of different delta sub lineages and locations:

AY.28 (Sri Lanka delta sub-lineage): 31/93. Detected from Colombo, Gampaha, Nuwaraeliya,
Balangoda, Bentota, Kuruwita, Potuwil
AY.104 (Sri Lanka delta sub-lineage): 43/93: Colombo, Bandaragama, Getahena, Gampaha
various places, Palindanuwara, Vavuniya, Waga, Welgama,
AY.122: Kosgama
AY.33: Kalutara
AY.4: Negombo
AY.61: Thalangama
AY.66: Puwakpitiya
B.1.617.2: Colombo, Gampaha, Trincomalee, Puwakpitiya
