USJ Department of Immunology found Omicron variant from a Nigerian Passenger

The report of whole genomic sequencing of the SARS-CoV-2 variants in 91´«Ã½ 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 91´«Ã½. The study was carried out by USJ researchers including Ìý²¹²Ô»åÌý

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.
