Identification of SARS CoV‐2 Omicron BA.1 and a novel Delta lineage by rapid methods and partial spike protein sequences in Sulaymaniyah Province, Iraq
Abstract:Background: Five variants of concern (VOCs) of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) have been globally recorded including Alpha, Beta, Gamma, Delta, and Omicron. The Omicron variant has outcompeted the other variants including the Delta variant. Molecular screenings of VOCs are important for surveillance, treatment, and vaccination programs. This study aimed to identify VOCs by using rapid inexpensive methods and partial sequencing of the virus's spike gene.Methods: Mutation-specific rR… Show more
“…A cycle threshold (Ct) below 40 (< 40) was considered positive. In addition, a conventional RT-PCR was employed on all SARS-CoV-2-positive samples to amplify partial spike (S) gene (748 bp) for sequencing [11].…”
