Expert throws more light on COVID-19 variants

Published

on

Dr. Patrick Obinna, a virologist based in Abuja, says viruses constantly change through mutation, advising Nigerians to continue taking preventive measures against the Corona virus (COVID-19).

Obinna told our correspondent, on Tuesday in Abuja, that it was important for Nigerians to continue observing protocols such as wearing face masks, observing social and physical distances, and washing of their hands regularly.

He explained that when a virus had one or more new mutations it is called a variant of the original virus.

According to him, several variants of the virus (SARS-CoV-2) that cause coronavirus disease, are creating global concerns.

“These variants include: Alpha. (B.1.1.7), Beta (B.1.351), Gamma (P.1), Epsilon (B.1.427), Epsilon (B.1.429) and Delta (B.1.617.2).

“These COVID-19 variants appear to spread more easily, and might have an increased risk of hospitalisation and even death.

“Some of them reduce the effectiveness of some monoclonal antibody medications, and the antibodies generated by a previous COVID-19 infection or a COVID-19 vaccine.”

Speaking of the Delta variant, he said that the call for caution was coming at a time when research in Australia indicated how easily the variant could potentially spread.

“It is clear that the Delta variant has a substantial transmission advantage, but scientists have not yet established why and they have also suggested three possible reasons:

“That the people it infects have a higher viral load, meaning they would emit more particles; that people will need to be exposed to less of the virus to become infected; or that a relatively short exposure time to an infected person is enough to spread the disease.

“It is possible that a person could be infected by being close to a carrier for a few seconds, if the carrier was to exhale a load of virus particles, and the person just happened to breathe in at exactly the wrong moment.

“It does not necessarily mean is that it is transmitting that way all the time for everybody. It may well just be one of those really unlucky moments.”

Obinna said that available COVID-19 vaccines were developed based on the COVID-19 virus before it had the mutations identified in these variants.

He added that while some research suggested that the vaccines have lower efficacy against the variants, the vaccines still appear to provide protection against severe COVID-19.

The expert stressed that further research was still needed, noting that vaccine manufacturers were also creating booster shots to improve protection against variants.

While urging Nigerians to take the COVID-19 vaccines, he said that the hope was that, acquired immunity from the vaccines would indeed produce long-lasting protection against SARS-CoV-2 and bring an end to the pandemic.

“These new findings point encouragingly in that direction.

“They also serve as an important reminder to roll up your sleeves for the vaccine if you have not already done so, whether or not you have had COVID-19.

“Our best hope of winning this contest with the virus is to get as many people immunised now as possible. That will save lives, and reduce the likelihood of even more variants appearing that might evade protection from the current vaccines,” Obinna admonished.

Meanwhile, he called on the Presidential Steering Committee (PSC), to expand its vaccination campaign to include all 15 to 17 year-olds to avoid a jump in infections among schoolchildren across the country.

According to him, the number of cases in the country is relatively low by global standards.

He acknowledged that COVID-19 would most likely be in the country for a longer period of time; adding that it was therefore, advisable to establish sustainable response and mitigation while working against global vaccine inequity.

He advised Nigerian authorities to reassess COVID-19 regulations and enforce the wearing of face masks everywhere to curtail the Delta variant when it eventually gets into the country.

“By so doing the country would avoid a multiple lockdowns.

“The entrance of the Delta variant across the globe has changed the transmission dynamics, so there is need for the PSC to re-strategise,” Obinna added.

Meanwhile, the Nigeria Center for Disease Control (NCDC), has said that after 40 sequences, the country was yet to detect the Delta variant.

Milestone; Kwara LG Declared Open Defecation Free by FG

Published

on

Stephen Olufemi Oni, Ilorin

The Federal Ministry of Water Resources and Sanitation has officially declared Oke-Ero Local Government Area (LGA) in Kwara State as Open Defecation Free (ODF), following a comprehensive validation exercise conducted by the National Task Group on Sanitation (NTGS).

The validation exercise was carried out between 21st and 25th July, 2025 by the NTGS, during which Oke-Ero LGA was assessed in accordance with the revised national ODF protocol. Based on the findings, the LGA was found to have met all required indicators and was therefore approved for ODF status on 27th August, 2025.

The official communication of this development was conveyed to Mr. Olorunfemi Adewumi Oladipo, the General Manager of the Kwara State Rural Water Supply and Sanitation Agency (RUWASSA), through a formal letter authored by the Director of Water Quality Control and Sanitation at the Federal Ministry; Mrs. Elizabeth Ugoh. The letter was issued on behalf of the Minister of Water Resources and Sanitation.

Mrs Elisabeth Ugoh, who congratulated the Kwara State Government and the people of Oke-Ero on achieving this national milestone, noted that sanitation is a continuous activity.

The correspondence described the achievement as a significant step forward in the national effort to eradicate open defecation and commended the sustained efforts of the local government, community leaders, stakeholders, and sanitation partners.

It would be recalled that the NTGS validation team conducted detailed assessments across households, institutions, and public spaces in Oke-Ero LGA, confirming the absence of open defecation and the presence of functional sanitation facilities, hygiene awareness, and sustained behavioural change, all of which are prerequisites under the national ODF criteria.

As part of the formal process, the Minister, Prof. Engr. Joseph Terlumun Utsev, is expected to communicate this achievement in writing to Governor AbdulRahman AbdulRazaqn, as, in line with established national protocol, the Governor is expected to host an official event to commemorate the ODF declaration of Oke-Ero LGA.

Reacting to the development, the Commissioner for Water Resources, Hon. Yinusa Lade, lauded the milestone as a testament to the state’s unwavering commitment to improving sanitation and public health. He commended the people of Oke-Ero for their resilience, cooperation, and ownership of the sanitation initiatives, which he described as critical to the sustainability of this achievement.

Hon. Lade, who reiterated the State government’s commitment to scaling up similar interventions across other LGAs, noted that with Oke-Ero setting the pace, the Ministry will intensify efforts to ensure that the entire State is declared Open Defecation Free well ahead of the national 2030 target.

Responding to the announcement, Mr. Oladipo expressed appreciation for the recognition, describing it as a reflection of collaborative effort across multiple levels of governance and community participation. Mr Olorunfemi Oladipo reaffirmed RUWASSA’s continued commitment to supporting other LGAs in the State to achieve similar results.

Mr Oladipo also urged local authorities and stakeholders in Oke-Ero to ensure the sustainability of this status, by adhering to the recommendations outlined in the validation report, which has been enclosed with the official communication.

This development positions Kwara State as one of the leaders in sanitation progress and contributes meaningfully to Nigeria’s broader objective of eliminating open defecation nationwide by 2030, in alignment with the Sustainable Development Goals (SDGs).

Nigeria Records 43,000 Snakebite Annually, Experts Urge Local Anti venom Production

Published

By Hassan Taiye

The Toxinological Society of Nigeria (TSN) has called on the federal and state governments to invest in local anti venom production and strengthen healthcare facilities to curb the rising burden of snakebite envenoming across the country.

This was contained in a communique issued by the Society’s Secretary-General, Dr. Mustapha Shehu Muhammad, at the end of its 2nd Annual General Meeting held between September 14 and 17 at Gombe State University.

The four-day conference, with the theme “Exploring Indigenous Anti-Venom Development and Therapy in Nigeria: Policies, Challenges and Opportunities,” attracted over 1,000 participants, including policymakers, clinicians, researchers, traditional leaders, and students.

Experts at the meeting disclosed that Nigeria records about 43,000 snakebite cases every year, leading to nearly 1,900 deaths, with children accounting for 30 percent of victims.

They identified delayed treatment, the high cost of anti venom, and inadequate facilities especially in rural areas as key factors worsening outcomes.

In his keynote address, Prof. Abdulrazak Habib stressed the urgent need for government and private sector collaboration in developing indigenous anti venom, warning that failure to act would worsen mortality rates and economic losses.

Delegates also visited the Snakebite Treatment and Research Hospital in Kaltungo, describing it as overstretched and in dire need of expansion.

The Society recommended establishing a National Centre of Excellence for Venom, Anti venom, and Natural Toxins Research in Gombe, and upgrading the Kaltungo hospital into a fully equipped National Snakebite Hospital with modern equipment, surveillance systems, and training capacity.

It further urged the Gombe State Government to dedicate at least one percent of its internal revenue to snakebite response, including free anti venom distribution, and to integrate snakebite research and training into the curriculum of Gombe State University.

FG Strengthens Border Checks as Fresh Ebola Outbreak Spreads in DRC

Published

By: Fabian Apechihin

The Federal Government has stepped up health surveillance at all entry points into Nigeria following the confirmation of new Ebola Virus Disease (EVD) cases in the Democratic Republic of Congo (DRC).

Director of Port Health Services, Federal Ministry of Health and Social Welfare, Dr. Akpan Nse, announced on Friday that airports, seaports, and land borders are now under reinforced monitoring. Additional personnel, backed by the World Health Organisation (WHO), have been deployed nationwide, while thermal scanners at airports are being serviced in partnership with private firms to ensure continuous operation.

Health authorities in the DRC on September 5 confirmed an outbreak of the Ebola Zaire strain in Kasai Province, with 28 suspected cases and 16 deaths, including four health workers. The country, which has recorded 15 outbreaks since 1976, last battled the virus in 2022.

Dr. Nse warned that Nigeria remains at risk due to heavy travel links with the DRC. He said all passengers arriving from Congo or transiting through the country must undergo mandatory screening and complete health declaration forms.

“We have intensified surveillance at every point of entry,” he said. “All arrivals from Congo are screened—by air, land, or sea. We are on full alert to prevent importation of the virus into Nigeria.”

Ebola is a highly fatal disease transmitted through direct contact with the blood or bodily fluids of infected persons or animals, particularly fruit bats, which are considered natural carriers.
