Emmanuel Addai, a Ghanaian Ph.D. researcher specializing in Mathematical and Data-driven Modeling of infectious disease and cyber forensics at the University of Arkansas at Little Rock, has co-authored a pioneering study that reveals how the rapid growth of online food delivery services is fueling the spread of food-borne illnesses.
In the peer-reviewed article, Addai and his collaborators developed a mathematical model that incorporates both human and insect populations (particularly flies) to simulate how food safety is compromised during doorstep food deliveries.
The model uniquely uses fractional calculus (Caputo operator) to reflect real-world memory effects such as poor hygiene practices and delayed policy responses.
The study shows that:
• Asymptomatic carriers, delivery personnel, and flies are critical transmission vectors.
• Government interventions such as food safety training for restaurant staff and stricter hygiene enforcement can significantly reduce outbreaks without disrupting food delivery services.
• The model was proven stable and accurate under rigorous mathematical conditions and tested using numerical simulations in MATLAB.
By integrating public health, data science, and mathematical modeling, Addai’s work provides a policy-ready framework for managing infectious outbreaks in urban food systems.
This research aligns with global food safety goals and supports the UN Sustainable Development Goals (SDG 3, 11, and 12).
For Ghana and beyond, this research underscores the urgent need for better regulation, monitoring, and public health oversight of digital food platforms, particularly in rapidly urbanizing and densely populated cities.
As the online food delivery industry continues to grow, especially in emerging economies such as Ghana, Nigeria, Kenya, and India, the lack of standardized food safety protocols and oversight for delivery chains has emerged as a major public health risk.
Emmanuel Addai’s research provides an evidence-based mathematical framework for policymakers to anticipate and manage these risks through optimal interventions.
This work is particularly impactful for developing nations, where informal food vendors and under-regulated delivery systems often operate outside the scope of national health standards.
His model can be adapted to simulate various real-world conditions urban slums, peri-urban hubs, and even cross-border trade routes, allowing government agencies and health departments to simulate outbreak scenarios, prioritize inspection strategies, and develop early-warning systems.
Furthermore, Addai’s contribution supports Ghana’s national priorities under the Ghana Food Safety Policy and aligns with UN Sustainable Development Goals (SDGs), especially:
• SDG 3: Good health and well-being,
• SDG 11: Sustainable cities and communities,
• SDG 12: Responsible consumption and production.
Ultimately, Emmanuel Addai’s contribution stands as a critical bridge between theoretical science and practical policy application, enabling stakeholders to make data-driven decisions in regulating the fast-growing online food delivery ecosystem.
This makes his research not only nationally important to Ghana’s public health strategy but also internationally recognized as a novel methodology applicable in both low- and high-income settings.

The New Patriotic Party (NPP) has strongly criticised the decision of the Court of Appeal to acquit and discharge former Chief Executive Officer of the Microfinance and Small Loans Centre (MASLOC), Sedinam Christine Tamakloe Attionu.
In a statement issued on July 30, 2026, the party described the ruling as a “travesty of justice” and claimed it was politically motivated.
The Court of Appeal on Thursday overturned her conviction and 10-year prison sentence, which had been imposed by the High Court in April 2024 on charges including stealing, causing financial loss to the state, money laundering and breaches of the Public Procurement Act.
According to the NPP, the former MASLOC boss was tried for five years and convicted after the High Court examined evidence relating to alleged financial irregularities during her tenure between 2013 and 2016.
The party noted that she left Ghana while the trial was ongoing and was later extradited from the United States, arriving in Ghana on June 9, 2026.
The NPP argued that the trial court had found that her actions caused a loss of nearly GH¢90 million to the state and that the evidence against her was substantial.
It questioned why the conviction was overturned barely seven weeks after her return to Ghana.
The party further accused the Attorney-General of using state institutions to protect people connected to the governing party.
It claimed that several cases involving persons affiliated with the government had been discontinued since January 2025 and that the acquittal of Madam Tamakloe Attionu was part of that pattern.
The NPP linked the decision to the ongoing case involving its Ashanti Regional Chairman, Bernard Antwi Boasiako, popularly known as Chairman Wontumi.
It called for his immediate acquittal and discharge, arguing that his conviction was also politically motivated.
The party demanded that the Attorney-General publish details of all cases involving persons linked to the governing party that have been withdrawn, discontinued or otherwise terminated since January 2025, including the reasons for those decisions.
It called on the Judicial Council and the leadership of the Judiciary to take steps to restore public confidence in the justice system.
The NPP said it would pursue all lawful avenues, including a possible review at the Supreme Court where applicable, to ensure accountability in cases involving public funds.
The party maintained that the fight against corruption must not be selective and that public resources belong to all Ghanaians.

Former Attorney-General Godfred Yeboah Dame has disagreed with the Court of Appeal’s decision to acquit former MASLOC Chief Executive Officer Sedina Tamakloe Attionu, insisting that the prosecution proved its case beyond reasonable doubt.
Mr Dame made the remarks after the Court of Appeal unanimously overturned her conviction and 10-year prison sentence.
He maintained that the evidence presented by the prosecution during the trial was credible and sufficient to support the conviction.
According to him, Ms Tamakloe absconded after she had been confronted with evidence led by the prosecution.
Mr Dame questioned the basis for the acquittal and suggested that the current Attorney-General should explain what led to the Court of Appeal’s decision.
He wondered whether the appeal had been strongly opposed by the state.
When asked whether he would advise the Attorney-General to challenge the ruling, Mr Dame answered in the affirmative.
“Oh, definitely,” he stated.
The former Attorney-General spoke about the ongoing criminal case involving former Finance Minister Ken Ofori-Atta.
He indicated that an application for stay of proceedings filed at the High Court had been dismissed, and that a fresh application had been filed at the Court of Appeal.
Mr Dame argued that the charge sheet in the case was defective and that the appellate court should determine the issue before the trial proceeds.
He further criticised the decision to hear the case during the legal vacation, describing it as an “unjustified haste” and saying such trials had not been conducted during vacation periods in the past.
Mr Dame said his legal team would formally protest the directive allowing the case to proceed during the vacation.
The Court of Appeal’s ruling in favour of Ms Tamakloe has become a major legal and political issue, with the Attorney-General’s Department already announcing plans to appeal the decision at the Supreme Court.
