NCDC Allays Fears Over COVID-19 XEC Variant

The Nigeria Centre for Disease Control and Prevention (NCDC) yesterday allayed fears over the newly detected COVID-19 XEC variant reportedly in circulation in Australia.
The NCDC, in a statement, yesterday, noted that the National COVID-19 Technical Working Group continues to monitor and conduct analyses of surveillance data both internationally and across the country to guide public health response activities.
It also said in line with the emergency preparedness and response strategy, it has continuously upgraded and updated the strategies and capabilities for a quick and effective response; and a dynamic risk assessment/readiness assessment is being organised to guide in developing a plan of action.
The Federal Government, had through the Federal Ministry of Health and Social Welfare, urged health authorities to activate heightened alert systems in response to the newly detected XEC COVID-19 variant that is rapidly spreading across the globe.
XEC is the latest in a long list of past and current COVID variants being monitored as the COVID-19 virus naturally evolves.
This directive comes after the strain, first identified in Australia, has now been confirmed in 29 countries.
This was contained in a letter dated December 5, addressed to the Committee of Chief Medical Directors and Medical Directors, by the ministry’s Permanent Secretary, Head of the Teaching Hospital Division, Dr. O.N. Anuma.
The letter read, “I am directed to inform you of a newly detected XEC COVID-19 variant which has been reported in Australia and has already spread to 29 countries globally.
“You may wish to know that this variant has shown a growth advantage over other circulating strains, raising concerns about its potential impact on public health.”
Anuma emphasised the need for vigilance and immediate action.
“Alert systems should be immediately activated throughout our hospitals for high index of suspicion in patients with COVID-like symptoms,” he stated.
The directive also highlighted the importance of collaboration and timely information-sharing among health institutions and the Federal Ministry of Health and Social Welfare to ensure an effective response.
Medical professionals are also urged to enhance monitoring protocols and share critical data on the XEC variant.
“We request your committee to collaborate with all relevant stakeholders to share critical data regarding this strain and implement enhanced monitoring protocols.
“Timely information sharing among relevant stakeholders including the Federal Ministry of Health will be vital for effective response strategies,” he warned.
However, NCDS said there is no need for unnecessary anxiety or panic over the disease variant.
The Agency, in a statement yesterday, said, “The Nigeria Centre for Disease Control and Prevention considers it necessary to make this statement to allay the fears created in the public space about the Covid-19 variant reportedly in circulation in Australia. The recent detection of the SARS-CoV-2 XEC sub-variant—a descendant of the Omicron lineage—has highlighted the ongoing evolution of the COVID-19 virus.
“For the information of our people, there are many variants of SARS-COVID-2 being monitored globally. Currently, the JN.1, classified as the Variant of Interest, is now reported in 132 countries, including the United States, India, Australia, the United Kingdom, China, New Zealand, Thailand, Canada, and Singapore, and Nigeria. A VOI is not yet deemed to pose serious risk.
“The XEC is a subvariant of JN.1 and has been designated as the Variant Under Monitoring i.e. being watched for potential concerns and not considered to pose a significant risk, and not yet meet the criteria for designation as VOI.
“There has been a reported rise in COVID-19 cases linked to the XEC variant, which has been detected
so far in 43 countries across different continents, Europe, Asia, North America, and recently in Botswana, Africa. Though the JN.1 has been reported in Nigeria since January 2024, the XEC variants, which are descendants of the Omicron lineage JN.1 are yet to be detected in Nigeria.”
NCDC noted that the JN.1 sub-variants are dominant globally and are the fastest growing among currently circulating variants of SARS-CoV-2.
It added that while the XEC subvariant has exhibited higher transmissibility as compared to other variants, it has not shown evidence of increased severity.
“The National COVID-19 Technical Working Group continues to monitor and conduct analyses of surveillance data both internationally and across the country to guide public health response activities.
“In line with our emergency preparedness and response strategy, we have continuously upgraded and updating our strategies and capabilities (surveillance, detection, stockpiling, training inclusive) for a quick and effective response. Along this line, a dynamic risk assessment / readiness assessment is being organised to guide us in developing a plan of action.
“Meanwhile, we urge all health facilities, both public and private, to increase the testing for COVID-19 on suspected patients. All positive samples are encouraged to be sent to the NCDC laboratory and other public health accredited laboratories for sequencing,” it said.
It noted that “COVID-19 remains a significant risk, particularly for the elderly, individuals with underlying chronic illnesses, those undergoing cancer treatment, organ transplant recipients, and individuals with suppressed immune systems,” it added.
The agency advised the public to continue to adhere to the basic public health safety measures and simple precautions such as maintaining good personal hygiene; covering of mouth and nose with a tissue when coughing or sneezing or into a bent elbow, using an alcohol-based hand sanitiser containing at least 60 per cent alcohol if soap and water are not available; wearing masks; physical distancing; staying vigilant; getting tested; and getting vaccinated.
It encouraged healthcare workers to test patients presenting with respiratory or febrile symptoms; practice hand hygiene, use personal protective equipment, and follow hospital-based infection prevention and control measures to limit disease spread.
It also urged state governments and policy makers to promote public health campaigns to educate communities about preventive measures and the importance of seeking medical attention early.
