The Nigeria Centre for Disease Control (NCDC) has confirmed the index case of the delta variant of the coronavirus in Nigeria.

The NCDC disclosed this in a statement on Thursday.

According to the NCDC, the variant was detected during routine tests for in-bound travellers in Abuja.

“The Nigeria Centre for Disease Control (NCDC) has detected a confirmed case with the SARS-CoV-2 Delta variant, also known as lineage B.1.617.2. The variant was detected in a traveler to Nigeria, following the routine travel test required of all international travelers and genomic sequencing at the NCDC National Reference Laboratory, Abuja,” the statement reads.

“The Delta variant is recognised by the World Health Organisation (WHO) as a variant of concern, given its increased transmissibility. The variant has been detected in over 90 countries and is expected to spread to more countries.

“The variant has also been linked to a surge in cases in countries where it is the dominant strain in circulation. There are ongoing studies to understand the impact of the variant on existing vaccines and therapeutics.”

The development comes days after the World Health Organisation (WHO) expressed concern over the “speedy” spread in infection rates in Africa as countries battle a third wave of COVID-19.

In a statement issued on July 1, the WHO had raised concern over variants of concern, especially the delta variant, adding that infection rates are doubling every week, and the virus is spreading faster than previous records.

However, according to the NCDC, the federal government is stepping up efforts through collaboration with the “Nigerian Institute of Medical Research (NIMR), African Centre for Genomics of Infectious Diseases (ACEGID), and other laboratories within the national network, to carry out genomic sequencing”, in order “to enable the detection of variants of concern, and initiate response activities”.

“Given the high transmissibility of the Delta variant and following its detection in Nigeria, NCDC urges all Nigerians to ensure strict adherence to public health and social measures in place. Proven public health and social measures such as physical distancing, frequent handwashing, and proper use of face masks, prevent infections and save lives. The COVID-19 vaccine is safe and effective and offers protection against the disease,” the agency said.

“Additionally, states are urged to ensure sample collection and testing for COVID-19 is accessible to the public. Public settings such as schools with accommodation facilities, workplaces and camps should utilise the approved Antigen-based Rapid Diagnostic Test (RDT) for rapid testing of their population.

“The recommended control measures to limit the spread of the Delta variant continue to be testing, following the existing public health guidance and abiding by the current travel and public restrictions.”
