Rwanda has reported a Marburg virus outbreak with several confirmed cases and deaths, making it a country of concern for public health.
About the Marburg Virus
The Marburg virus is a highly dangerous virus that causes Marburg Virus Disease (MVD), also known as Marburg Hemorrhagic Fever.
It belongs to the same family of viruses as Ebola (the filovirus family).
MVD has a case fatality rate that can range from 24% to 88%, depending on the virus strain and how cases are managed.
The virus was first identified in 1967 during simultaneous outbreaks in Marburg and Frankfurt in Germany.
How does it spread?
The Marburg virus initially spreads from animals to humans, primarily through exposure to Rousettus bats, particularly the Egyptian fruit bat, found in caves or mines.
Once a person is infected, it can spread from human to human through:
Direct contact with the blood, and bodily fluids (urine, saliva, sweat, vomit, feces, breast milk, and semen) of an infected person.
Indirect contact with surfaces or objects like bedding or clothing that have been contaminated with these fluids.
Medical workers are often at risk, especially during outbreaks, due to contact with patients when proper infection control practices are not followed.
The virus does NOT spread through the air like the common cold or flu.
Symptoms and Treatment
Symptoms typically begin between 2 to 21 days after exposure to the virus.
Early symptoms are: High fever, severe headache, Muscle aches, Chills, Severe watery diarrhoea, abdominal pain and cramping, nausea and vomiting.
As the disease progresses, more severe symptoms may develop, including: Bleeding (both internal and external) ex—blood in vomit and faeces.
Patients often die 8 to 9 days after the onset of symptoms, primarily from severe blood loss and multiple organ failure.
Currently, there are no approved vaccines or specific antiviral treatments for MVD. However, supportive care can improve the chances of survival.
Supportive treatment includes:
Rehydration with oral or intravenous fluids to maintain fluid and electrolyte balance.
Treatment of specific symptoms like fever, pain, and diarrhoea.
Blood transfusions and oxygen therapy may be required for severe cases.

Mentor’s Comment: After the U.K. committed to phasing out coal by 2025, it had already reduced coal usage to just 20% of its energy needs. The country focused on a comprehensive transition that supported the workforce and the communities reliant on coal.
In contrast, India has set a longer timeline of 45 years (until 2070) to reach net zero emissions and has made significant strides in increasing renewable energy capacity. However, coal usage has also risen, necessitating the establishment of clear timelines for shutting down coal plants and implementing regional redevelopment programs.
This is crucial as many coal-dependent areas in India are among the poorest. In today’s editorial, we need to ensure an inclusive and fair transition. India needs a well-planned, transparent approach that addresses the unique challenges faced by these communities.

Let’s learn!
Why in the News?
The closure of the UK’s last coal-fired power plant marks a significant milestone in the global transition to clean energy, reflecting a broader paradigm shift away from coal reliance.
However, this transition has faced challenges and requires tailored strategies for developing nations, as the UK’s experience illustrates a complex history influenced by environmental legislation and geopolitical factors over several decades.
Key Highlights of India’s Performance at Glasgow COP26 Summit:
•Net Zero Commitment: India announced its first-ever net zero emissions target for 2070, which was seen as a significant but late commitment compared to other countries aiming for 205013. •Five Key Targets: Prime Minister Narendra Modi outlined five commitments (Panchamrit) for India, including: 1. Achieving 500 GW of non-fossil electricity capacity by 2030. 2. Meeting 50% of energy needs from renewable sources by 2030. 3. Reducing total projected carbon emissions by one billion tonnes by 2030. 4. Reducing emissions intensity of GDP by 45% from 2005 levels by 2030. •Focus on Developed Nations: India’s stance emphasized the responsibility of developed countries to provide climate finance and technology transfer, reflecting a call for equity and climate justice in global efforts45. •Criticism: While some activists criticized the 2070 target as insufficiently ambitious, it was viewed positively within India, highlighting the country’s recognition of its role in global climate action amidst its developmental needs13.
Present Dilemma: India and the U.K. are on different paths toward achieving net zero emissions, with India advocating for “phasing down” coal rather than an outright phase-out, as seen at the 2021 Glasgow COP where it pledged to reach net zero by 2070 and meet half its energy needs from renewables by 2050.
Present Status of Cumulative Emissions:
An analysis by Carbon Brief indicated that the U.K. has emitted 10.4 billion tonnes historically, ranking it fourth globally due to its colonial carbon footprint.
India’s per capita emissions were 2 tonnes in 2023, which is less than half the global average (4.6 tonnes) and about a third of the U.K.’s per capita emissions (5.5 tonnes) despite having a population over 20 times larger.
India relies heavily on coal for energy, with about 70% of its energy output coming from coal-fired plants, and it has more than 350 operational mines.
The coal sector employs around 340,000 miners directly, with additional jobs in thermal power plants, highlighting the economic implications of transitioning away from coal.
India’s coal production and consumption are expected to peak between 2030 and 2035, while the country aims to increase its renewable energy capacity significantly.
Despite rising coal use, India is also rapidly expanding its renewable energy capacity, aiming for a balanced approach to meet growing energy demands while addressing climate goals.
India’s Coal Story:
In 1774: India’s first coal mine, the Raniganj coalfield was by the British East India Company, leading to extensive coal extraction across eastern and central states.
In 1920: The Hussain Sagar Thermal Power Station, India’s first coal-fired power plant (1920), began operations, followed by the Trombay power station in 1956, which solidified thermal power as a primary energy source.
In 2022: Britain’s per capita energy consumption was nearly three times that of India, highlighting disparities in energy usage.
At Present, approximately 70% of India’s energy output comes from coal, with around 218 GW of installed capacity and over 350 operational mines, alongside plans for 120 new mines.
What lessons can India learn from the UK’s coal phase-out?

Scientists at the Institute of Nano Science and Technology (INST), Mohali, in collaboration with other researchers have developed the Combination Therapeutic Clotting Implant.
What is the Combination Therapeutic Clotting Implant?
It is a hybrid implant made of metal-based nano-medicine combined with patient-derived blood clotting components.
It is designed to reduce localized tumor recurrence after surgery.
It uses nanotechnology and autologous fibrin (derived from the patient’s own blood) to enhance post-surgical cancer treatment by providing localized therapy and promoting healing in the tumor bed.
How does It Work?
The implant is created using Nano-Micro-Sera (NMS), which consists of drug and metal-based nanomedicine stabilized by the patient’s own serum protein corona.
The hybrid implant is reinforced into autologous fibrin, which quickly bonds with damaged tissue in the tumor bed after surgery.
Once the surgical site is closed, the implant delivers localized chemo-phototherapy, triggering immunogenic cell death (ICD).
This process activates dendritic cells and T-cells, which boosts the body’s immune response and prevents the recurrence of tumors.
Significance of the Implant
The implant offers an affordable and effective solution for localized post-surgical cancer management, especially for marginalized patients.
By using the patient’s own serum proteins and fibrin, the implant ensures personalized treatment, reducing the risk of systemic toxicity.
The implant’s design is resource-efficient, making it accessible for bedside fabrication with simple equipment, ensuring wider availability.
It has demonstrated superior outcomes in suppressing recurrent breast tumors, and its use could prevent tumor recurrence and reducing the chances of metastasis.
