Scientists Identify 6 Distinct Types of COVID-19

Scientists have claimed that there are six distinct ‘types’ of Covid-19, each distinguished by a particular cluster of symptoms in patients, findings, if validated, can help physicians better diagnose and monitor those infected with the novel coronavirus.

The yet-to-be peer reviewed study, published in the medRxiv preprint platform, used a machine learning algorithm to analyse data from a subset of around 1,600 users of the Covid Symptom Study app in the UK and US with confirmed Covid-19, who had regularly logged their symptoms between March and April.
It analysed if particular symptoms appeared together, and how this was related to the progression of the disease.
According to the scientists, led by those from King’s College London in the UK, the findings have major implications for the clinical management of Covid-19 patients.
“These findings have important implications for care and monitoring of people who are most vulnerable to severe Covid-19,” said Claire Steves, a co-author of the study from King’s College London.
They said the research can also help doctors predict who is most at risk and likely to need hospital care in a second wave of coronavirus infections.
The study noted that patient symptoms can fall under one of the six following categories: ‘flu-like’ with no fever, ‘flu-like’ with fever, gastrointestinal, severe level one with fatigue, severe level two with confusion, and severe level three accompanied by abdominal and respiratory pain.
In the first category of patients who reported ‘flu-like symptoms with no fever, the scientists said the manifestations included loss of smell, muscle pains, cough, sore throat, chest pain, but no fever.
According to their analysis, those in the second category had headache, loss of smell, cough, sore throat, hoarseness, fever, and loss of appetite, and those in the gastrointestinal symptoms cluster had a combination of headache, loss of smell, loss of appetite, diarrhea, sore throat, chest pain, but no cough.
Under the ‘severe level one with fatigue’ category, the scientists said patients reported loss of smell, cough, headache, fever, hoarseness, chest pain, and fatigue, and those with the level two of severity expressed these same symptoms with the addition of loss of appetite, sore throat, confusion, and muscle pain.
In the most severe category, the study noted that patients experienced headache, loss of smell, loss of appetite, cough, fever, hoarseness, sore throat, chest pain, fatigue, confusion, muscle pain, shortness of breath, diarrhea, and abdominal pain.
According to the research, all people reporting symptoms experienced headache and loss of smell, with varying combinations of additional symptoms at various times. It said some of the manifestations, such as confusion, abdominal pain and shortness of breath, are not widely known as Covid-19 symptoms, yet are hallmarks of the most severe forms of the disease.
The scientists also analysed if people experiencing particular symptom clusters were more likely to require breathing support in the form of ventilation or additional oxygen.
They discovered that only 1.5 per cent of people with cluster one, 4.4 per cent of those with cluster two and 3.3 per cent in cluster 3 required breathing support.
For clusters four, five, and six, the researchers said these figures were 8.6, 9.9, and 19.8 per cent respectively.
Nearly half of the patients in cluster six, according to the study, ended up in hospital, compared with just 16 per cent of those in cluster one.
People with cluster four, five or six symptoms tended to be older and frailer, and were more likely to be overweight, the scientists said, adding that these patients had pre-existing conditions such as diabetes or lung disease than those in the other types.
“If you can predict who these people are at day five, you have time to give them support and early interventions such as monitoring blood oxygen and sugar levels, and ensuring they are properly hydrated — simple care that could be given at home, preventing hospitalisations and saving lives,” Steves said.
Carole Sudre from King’s College London, one of the lead scientists part of the study, said the research illustrates the importance of monitoring symptoms over time to make predictions about individual risk and outcomes more sophisticated and accurate.
“This approach is helping us to understand the unfolding story of this disease in each patient so they can get the best care,” Sudre said.
“Being able to gather big datasets through the app and apply machine learning to them is having a profound impact on our understanding of the extent and impact of Covid-19, and human health more widely,” added Sebastien Ourselin, a senior author of the study from King’s College London.

FRC, ICPC Seal Anti-corruption Alliance

The Fiscal Responsibility Commission (FRC) and the Independent Corrupt Practices and Other Related Offences Commission (ICPC) have signed a memorandum of understanding (MoU) to enhance institutional synergy and accountability in public finance management.

The partnership is also to deepen transparency and strengthen the fight against corruption in Nigeria.
The Executive Chairman of the FRC, Mr. Victor Muruako, and the Executive Chairman of the ICPC, Dr. Musa Adamu Aliyu, expressed profound satisfaction over the partnership, describing the signing as timely and symbolic, coming on a day dedicated globally to integrity, transparency, and the fight against corruption.
Speaking at the ceremony, both chairmen reaffirmed their agency’s shared commitment to prudent management of Nigeria’s resources, fiscal discipline, and the coordinated strategies to confront corruption and financial mismanagement.
Under the MoU, both agencies will collaborate extensively in capacity building, joint investigations, information sharing, asset recovery, and enforcement operations.
The ICPC, through its Anti-Corruption Academy of Nigeria (ACAN), will provide specialised training to FRC staff in forensic investigations, financial crime detection, digital evidence recovery, and prosecution strategies. In turn, both agencies will exchange resource persons for workshops and public enlightenment programmes.
The agreement further empowers both institutions to conduct joint investigations and coordinated operations where violations cut across the mandates of both the Fiscal Responsibility Act, 2007 and the ICPC Act, 2000. It also establishes a framework for mutual assistance in tracing, freezing, confiscating, and recovering stolen public funds.
On information sharing, the MoU guarantees the confidential exchange of intelligence, financial records, and technical data, while upholding strict ethical standards and full compliance with all applicable laws.
According to the parties, the collaboration will significantly enhance Nigeria’s anti-corruption architecture by eliminating institutional silos and strengthening enforcement outcomes.
The Memorandum of Understanding, which can be terminated with a 30-day notice by either party, marks a renewed and expanded phase of cooperation between the two key integrity institutions.
The signing ceremony concluded with both chairmen reaffirming their resolve to work tirelessly to promote accountability, transparency, and sustainable national development in line with the Constitution of the Federal Republic of Nigeria and existing anti-corruption laws.
Meanwhile, the Chairman of the FRC, Victor Muruako, has commended the ICPC Chairman, Dr. Musa Adamu Aliyu, and his team for sustaining the Commission’s legacy as one of Nigeria’s frontline anti-corruption institutions. Muruako particularly highlighted the signing of the MoU between the two agencies, describing it as a major step toward strengthening inter-agency collaboration in tackling corruption at all levels of government.
According to him, both agencies have, in recent months, intensified joint efforts to enhance accountability and prevent corruption at the local government level. These efforts, he noted, focus on improved budget preparation, prudent management of public funds, and the modernisation of tax, financial and asset administration systems.
He emphasised that where acts of corruption are detected, the law must take its full course to deter future offenders.

Debt Rises in AI Data Centre Boom

As AI fever has propelled global stocks to record highs, the data centres needed to power the technology are increasingly being financed with debt, adding to concerns about the risks.

A UBS report last month said AI data centre and project financing deals surged to $125 billion so far this year, from $15 billion in the same period in 2024, with more supply from the sector expected to be pivotal for credit markets in 2026.
“Public and private credit seems to have become a major source of funding for AI investments, and its rapid growth raised some concerns,” said Anton Dombrovskiy, fixed income portfolio specialist at T. Rowe Price.
“Although up until now an increase in supply has been met with relatively healthy demand, this is the area to watch especially taking into account large financing needs estimates,” Dombrovskiy added.
The Bank of England warned last week that the growing role of debt in the AI infrastructure boom could heighten potential financial stability risks if valuations correct.
Christopher Kramer, portfolio manager and senior trader on Investment Grade Credit team at Neuberger told Reuters that the market has seen a structural shift as the largest technology companies finance their AI infrastructure ambitions.
“They really haven’t been focal points in our market from a debt issuance standpoint, and that’s obviously shifting really dramatically … anytime you have that, it creates a lot of opportunity,” he said on November 28.
“We’re excited just from the standpoint that the market’s changing. You’re going to have a different dynamic, it creates an opportunity to take risks and create value for our investors,” Kramer added.

FG to Use Digital Economy Initiatives to Curb Corruption Among Youth

Lateef Fagbemi (SAN), the Attorney-General of the Federation and Minister of Justice, has said that Federal Government is intensifying its use of digital-economy initiatives to curb corruption among young Nigerians.

Speaking at the commemoration of the 2025 International Anti-Corruption Day held on Tuesday in Abuja, the AGF said the administration of President Bola Ahmed Tinubu has deliberately positioned technology, innovation training, and digital-skills development at the heart of its anti-corruption strategy for young people.
The event, organized by Technical Unit on Governance and Anti-Corruption Reforms (TUGAR) domiciled at the Nigeria Extractive Industries Transparency Initiative (NEITI) had the theme: “Uniting with Youth Against Corruption: Shaping Tomorrow’s Integrity”.
Fagbemi, who delivered the keynote address, said the government believes that empowered, skilled and economically engaged youths are less vulnerable to corrupt influences.
According to him, programmes such as the 3 Million Technical Talents Programme (3MTT) and the recently launched Nigerian Youth Academy (NiYA) are already equipping millions of young Nigerians with ICT and digital-innovation skills, reducing their dependence on patronage systems that fuel corrupt practices.
“A hopeful youth is harder to corrupt; an engaged youth is harder to mislead; and an empowered youth is a powerful force for national transformation,” Fagbemi said.
He explained that by investing in digital literacy, tech entrepreneurship and innovation-driven training, the Tinubu administration aims to create a generation of young Nigerians who are globally competitive and resistant to corruption.
Beyond digital skills, the AGF pointed at several government efforts to expand educational access through the Nigeria Education Loan Fund (NELFUND), and support youth entrepreneurship via the Nigeria Youth Investment Fund (NYIF) and the iDICE programme, providing funding, training and mentorship for young innovators in tech, entertainment, agriculture and design.
Fagbemi added that the inclusion of young people in governance, through appointments and expanded civic-engagement platforms, was another strategic tool to strengthen integrity and transparency in public life.
He urged stakeholders to deepen efforts to integrate anti-corruption values into school curricula, establish integrity clubs, mentor young leaders, and leverage ICT tools to promote transparency, whistleblowing and public accountability.
Earlier, the Head of TUGAR, Mrs Jane Onwumere said the gathering was especially meaningful because it reflected a shared truth: that tomorrow’s integrity rests significantly in the hands of the youth.
“The theme therefore, is not just a slogan but a call to action and a reminder that young people are not only beneficiaries of good governance, they are co-architects of it.
“Corruption has affected lives and the economy negatively in many ways. One of such is the “japa wave” which has seen young Nigerians leave the country in droves in search of greener pastures. This syndrome has drained the country of resources and human capital. It has in many situations split the family unit, a critical foundation for anti-corruption efforts”, Onwumere, added.
In his speech, the Executive Secretary, NEITI, Hon. Musa Sarkin Adar expressed the agency’s commitment to empowering young Nigerians not only as advocates for accountability but also as active partners in shaping the future of integrity in the extractive industries and beyond.
“At NEITI, we recognize that corruption undermines opportunities for growth, distorts resource governance, and deepens inequality. We also know that a united, informed, and courageous generation can dismantle these barriers.
“This is why NEITI will continue to expand civic education, strengthen our reporting mechanisms, support youth-led innovation, and create more platforms for constructive engagement with young professionals, students, and entrepreneurs”, he added.
