welcome to the Epidemic Intelligence weekly Report, your essential resource for staying updated on critical health developments across Africa. This comprehensive report focuses on three core areas: the current epidemiological situation, risk evaluations, and the public health strategies being deployed by affected countries, partners, and the Africa CDC. Each week, we highlight events classified as moderate to very high risk, ensuring you remain informed about emerging threats.
Geographic Scope: Our coverage extends to individual nations or multiple countries, depending on the scale and impact of the event.
Selection Criteria: While the Africa CDC monitors all public health incidents, this report focuses on those posing moderate to very high risks, with fresh updates provided weekly.
Health Threats: From infectious diseases to natural disasters, we cover a wide range of health challenges. Our approach is holistic, addressing interconnected sectors—animal, environmental, and human health—to provide a comprehensive view.
Consider this Event-Based Surveillance Weekly Report your guide to understanding Africa’s public health dynamics. We equip you with the latest data and insights, empowering you to make informed decisions and take effective action toward a healthier, thriving continent.
Stay informed.Stay vigilant. Stay safe.

Understanding the Difference Between Weight and Mass
Weight and mass are often used interchangeably, but they represent distinct concepts in physics. mass refers to the amount of matter in an object, a fundamental property that remains constant regardless of location. Weight, on the other hand, is the force exerted on an object due to gravity. It varies depending on the gravitational pull of the planet or celestial body where the object is located.
For example,an object with a mass of 10 kilograms will have the same mass on Earth and the Moon. Though, its weight will differ as the Moon’s gravitational force is about one-sixth that of Earth’s. this distinction is crucial in fields like space exploration, engineering, and even everyday applications where precise measurements are required.
Understanding these differences not only clarifies scientific principles but also enhances our ability to solve real-world problems. Whether you’re designing a spacecraft or simply weighing ingredients for a recipe, knowing the distinction between weight and mass ensures accuracy and success.
Understanding the Relationship Between Newtons and Kilograms
When it comes to physics,the connection between Newtons (N) and kilograms (kg) is rooted in the fundamental principles of force and mass. At its core, this relationship is governed by Newton’s Second Law of Motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In mathematical terms, this is expressed as F = m × a.
In the International System of Units (SI), one Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (1 N = 1 kg·m/s²). This definition bridges the gap between force and mass, providing a clear framework for understanding how these units interact.
On Earth, gravity plays a significant role in this relationship.The acceleration due to gravity (g) is approximately 9.8 m/s² at the planet’s surface. This means that the weight of an object—essentially the force exerted by gravity—can be calculated using the formula G = m × g, where G represents the gravitational force, m is the mass, and g is the acceleration due to gravity. For example, a 1 kg object on Earth weighs about 9.8 N.
To summarize:
- 1 N = 1 kg·m/s²
- 1 kg on Earth’s surface weighs approximately 9.8 N
This explanation not only clarifies the conversion between Newtons and kilograms but also highlights the practical implications of these units in everyday physics. Whether you’re studying mechanics or simply curious about how forces work, understanding this relationship is essential.
How does the lack of access to preventive vaccines and timely diagnostics impact Africa’s ability to respond to health threats?
Interview with Dr. Amina Nkosi,Epidemiologist and Public Health Expert
Conducted by archyde News Editor,Sarah thompson
Sarah Thompson (ST): Welcome,Dr. Nkosi,and thank you for joining us today. as a leading epidemiologist and public health expert, your insights are invaluable, especially given the critical health developments across Africa. Let’s dive right in. The Africa CDC’s Epidemic Intelligence Weekly Report highlights the importance of monitoring moderate to very high-risk health events.Can you tell us about the current epidemiological situation in Africa as of January 2025?
Dr. Amina Nkosi (AN): Thank you, sarah. It’s a pleasure to be here. The epidemiological situation in Africa remains dynamic and challenging. As of January 2025, we are seeing a resurgence of infectious diseases in certain regions, exacerbated by factors such as climate change, population displacement, and gaps in healthcare infrastructure. The Africa CDC’s weekly reports are crucial in tracking these developments, particularly in areas with low surveillance and diagnostic capacities.
ST: You mentioned gaps in healthcare infrastructure. Could you elaborate on how these gaps impact the continent’s ability to respond to health threats?
AN: Absolutely. One of the most pressing issues is the lack of access to preventive vaccines and timely diagnostics.For example, in regions where healthcare systems are weak, outbreaks can escalate quickly before they are even detected. This was evident in the event of international concern on August 14, 2024, where delayed containment efforts led to widespread transmission. Strengthening surveillance and diagnostic capacities is critical to preventing such scenarios in the future.
ST: The Africa CDC has been working on a continent-wide response to these challenges. How effective have these efforts been so far?
AN: The Africa CDC has made significant strides in coordinating responses across the continent. Their focus on a holistic approach—integrating animal, environmental, and human health—has been particularly effective. As an example, their recent initiatives to improve cross-border collaboration and data sharing have enhanced our ability to detect and respond to outbreaks early. However,sustained investment and political will are essential to ensure these efforts are scalable and enduring.
ST: Looking ahead, what do you see as the biggest health threats facing Africa in 2025 and beyond?
AN: The biggest threats are multifaceted. Infectious diseases like malaria, cholera, and emerging zoonotic diseases remain persistent challenges. additionally, the impact of climate change is exacerbating these threats, with increased flooding and droughts creating ideal conditions for disease spread. We also cannot overlook the growing burden of non-communicable diseases, which are placing additional strain on already fragile healthcare systems.
ST: what message would you like to share with our readers about staying informed and vigilant in the face of these challenges?
AN: My message is simple: knowledge is power. Stay informed through reliable sources like the Africa CDC’s weekly reports.Support initiatives that strengthen healthcare systems and promote equitable access to vaccines and diagnostics.And most importantly, remember that public health is a collective responsibility—everyone has a role to play in building a healthier, more resilient Africa.
ST: Thank you,Dr. nkosi, for your time and expertise. Your insights are a reminder of the importance of vigilance and collaboration in addressing Africa’s public health challenges.
AN: Thank you,Sarah. It’s been a pleasure.
