The Director General, NCDC, Dr. Ifedayo Adetifa has revealed that Omicron COVID-19 variant first identified from testing done on Nov. 9, 2021 in Botswana on travellers from West Africa.
Adetifa spoke as Ontario Province in Canada reported Sunday that it found two cases of the variant on two persons with travel history to Nigeria.
Adetifa however said the Omicron variant has not been detected in tests conducted in Nigeria.
However, he said the centre is monitoring emerging evidence on the variant and its implication, to inform Nigeria’s response to the COVID-19 pandemic.
Botswana first identified the Omicron variant from testing done on Nov. 9, 2021 on travellers from West Africa.
It was reported to the World Health Organisation (WHO) on identification of cases among a cluster of young unvaccinated people in South Africa on Nov. 24, 2021.
While this variant has so far NOT been detected in Nigeria, a number of cases have now been reported in the UK, Israel, Botswana, Hong-Kong, Germany, Belgium, Italy and many more countries.
However, no deaths have been attributed to this new variant yet.
A total of 126 genomes of this variant have been detected globally and published on GISAID, a global mechanism for sharing sequencing data.
The SARS-CoV-2 variant has now been designated a variant of concern (VOC) and named Omicron by the WHO, as advised by the independent Technical Advisory Group on SARS-CoV-2 Virus Evolution (TAG-VE).
WHO has also urged countries to enhance their surveillance and virus sequencing efforts to increase their understanding of the circulating variants.
Adetifa said that the Federal Ministry of Health (FMOH) and NCDC are aware of reports of a new COVID-19 variant – the B.1.1.529 lineage.
“The FMOH and NCDC are monitoring emerging evidence on this new variant and its implication, to inform Nigeria’s response to the COVID-19 pandemic.
“Given the high number of mutations present in the Omicron variant and the exponential rise in COVID-19 cases observed in South Africa, this virus is considered highly transmissible and may also present an increased risk of reinfection compared to other VOCs,” he added.
He, however, said the fears about the variant’s ability to evade protective immune responses and/or its being vaccine resistant were only theoretical so far.
“This virus can still be detected with existing Polymerase Chain Reaction (PCR) tests.
“The WHO and researchers across the world are working at speed to gain understanding of the likely impact of this variant on the severity of COVID-19 and on the potency of existing vaccines and therapeutics,” he added.
The NCDC boss added that the agency would continue to ensure daily review of surveillance data and use this to inform public health decision making.
Therefore, he urged all States to ensure that sample collection and testing are accessible, so that travellers, people with symptoms or who have been exposed to COVID-19 cases get tested promptly.
He disclosed that the NCDC, through the National Reference Laboratory (NRL), would continue to coordinate genomic surveillance and other activities required for the detection of variants.
He assumed global spread of this variant had occurred and it is prioritising sequencing of recently-accrued samples from SARS-COV-2 positive travellers from all countries, especially those from countries that have reported the Omicron variant already.
“In collaboration with Port Health Services of the FMOH, enhanced surveillance is ongoing at the airports and points of entry, and to ensure compliance with current travel guidance, especially for the day 2 COVID-19 PCR testing.
“Should there be any changes to travel guidance, this will be communicated in due course.
“Considering the highly likely increased transmissibility of the Omicron variant and its emergence that is linked to unmitigated community transmission of the virus, the NCDC urges Nigerians to ensure strict adherence to the proven public health and social measures in place, which are enforceable by the Presidential Steering Committee on COVID-19 (PSC-COVID-19), through the COVID-19 Health Protection Regulations 2021.
“We are collectively responsible for our own health security, including playing our part to reduce the risk of the importation or spread of the Omicron variant in Nigeria,” he advised.
Adetifa implored Nigerians to do the following: ”Make every use of the currently available opportunities to get vaccinated against COVID-19.
“Adhere to public health and social measures that have been proven to help prevent SARS-CoV-2 infection regardless of the circulating variant. These include:
