Detection and upsurge of SARS-CoV-2 Omicron variant in Islamabad Pakistan

The SARS-CoV-2 omicron variant was first detected in South Africa in November, 2021 and has rapidly spread to more than 90 countries. The emergence of Omicron variant demands for enhanced genomic surveillance to track the mutation profile and spread of virus. In the current study, we have sequenced 15 whole-genome sequences of SARS-CoV-2 Omicron variant from Islamabad region of Pakistan. Among the 15 isolates, 66% were from Islamabad whereas 33% of cases had international travel history of United Kingdom, Maldives, South Africa, and Oman. The detection of Omicron in local community and in travelers highlights the need for rigorous screening at national level and at entry points in order to contain the spread of variant.
