How Nigeria is tackling COVID-19 variants

Abuja – As COVID-19 continues to unfold, the better the possibilities of more variants emerging. Since the onset of the pandemic, four variants of explain had been identified, with the Delta—first detected in India—being the most transmissible at demonstrate and dominant in quite rather a lot of nations. In Nigeria, Dr Chikwe Ihekweazu, the Director-Frequent of the Nigeria Centre for Illness Assist a watch on, explains how the nation is responding to the pandemic within the wake of the more infectious variants.

How be pleased COVID-19 variants affected the pandemic response in Nigeria?

The Delta variant is now the dominant stress in our nation and has been demonstrate in over 90% of samples tested. When the Delta variant changed into before all the pieces detected globally, Nigeria acted mercurial to introduce compulsory isolation of travellers from nations with high incidence of instances connected with the variant as an initial mitigation measure. We also revised our genomic surveillance strategy to sequence samples among travellers testing obvious on arrival in Nigeria as a method to employ variants mercurial.

As the Delta variant began to unfold within the nation, the major step changed into getting the discover obtainable mercurial to warn the final public. We scaled up our risk communications the employ of out of the ordinary and social media. One other priority changed into increasing capability to establish instances even sooner to cease the chain of transmission. We within the intervening time are working with different establishments in Nigeria to introduce the utilization of Snappily Diagnostic Assessments in public settings equivalent to faculties, formative years carrier camps, govt locations of work among others. Obviously, we now be pleased got also sustained different measures to present protection to these at elevated risk, along side supporting infection prevention and abet watch over in health products and providers and providing training to health team.

Nigeria is further strengthening genomic surveillance capability to establish and mercurial characterise emerging variants. The records from this also guides our insurance policies equivalent to compulsory testing for global travellers. We are also accomplishing stories on vaccine effectiveness and contributing to global scientific evidence. We can proceed to retain a obtain risk communications ability to fabricate sure Nigerians are responsive to the hazards offered by variants and proceed adhering to public health measures.

How is Nigeria scaling up genomic sequencing?

Nigeria has contributed sequences within the worldwide SARS-COV-2 genome repository maintained by World Initiative on Sharing All Influenza Knowledge. Extra samples are despatched for sequencing than ever earlier than, with 100% weekly fabricate bigger within the preference of samples sequenced. Here’s at demonstrate carried out by a community of five laboratories coordinated by the Nigeria Centre for Illness Assist a watch on’s Nationwide Reference Laboratory. We are also without warning scaling up capability for elevated testing to meet this want.

The Nigeria Centre for Illness Assist a watch on is now having a explore to replicate our successful efforts in building Nigeria’s capability for molecular testing of COVID-19 with capability building for genomic sequencing. We are in conversations with our companions equivalent to the UK’s Properly being Security Company given their strengths in pathogen genomics. We are also receiving abet from Africa Centre for Illness Assist a watch on and Prevention, which is coordinating continental efforts to scale up genomic sequencing.   

These efforts are now not handiest important for sequencing of SARS-CoV-2 samples, but for diverse pathogens that are endemic in Nigeria equivalent to the Lassa fever and yellow fever viruses.

Assorted boosting genomic surveillance, how can Nigeria make stronger outbreak readiness?

Within the final five years, the Nigeria Centre for Illness Assist a watch on has worked very hard to crimson meat up Nigeria’s capability to cease, detect and acknowledge to infectious illness outbreaks. Now we be pleased got constructed systems for coordination of outbreak preparedness and response thru Emergency Operations Centres at nationwide and subnational ranges, established a community of public health laboratories coordinated by Nigeria Centre for Illness Assist a watch on’s Nationwide Reference Laboratory, digitalized our infectious illness surveillance method, established unique programmes for infection prevention abet watch over, risk communications, antimicrobial resistance and several other different activities.

However, there’s serene a form of labor to be carried out. It’ll require obtain dedication by the government, enough, obtain and sustainable financing for health security and accountability to abet these.

Improved outbreak readiness might well presumably even require obtain collaboration — each with African nations and nations in different regions. This has been effectively illustrated by our response to the COVID-19 pandemic. We are grateful for collaboration platforms created by the World Properly being Group, Africa Centre for Illness Assist a watch on and Prevention and different companions to enable disagreeable-nation studying.

Why is genomic sequencing restricted in quite rather a lot of African nations?

There’s apparent inequality in sequencing capability globally, and the want to scale up this capability in African nations is awfully particular. For several a long time, there has been restricted focus and unhappy funding in genomic sequencing capability – each from African governments and companions.

However, the shuffle forward is to reduction and enable more nations on the continent to accumulate this capability. There’s proof from several fashions along side the utilization of govt, non-public and tutorial laboratories with coordination by nationwide public health institutes.

Now we be pleased got begun to fabricate progress with establishments in nations admire South Africa, The Gambia and several other others showing very perfect progress. The Africa Centre for Illness Assist a watch on and Prevention has also secured funding for pathogen genomics compare and pattern thru the Africa Pathogen Genomics Initiative which will abet nations. The pandemic has brought to fore the inequality that exists and the hazards we face if we create now not accumulate genomic sequencing capability in African nations.
