After mpox outbreak, Africa is under the threat of yet another virus outbreak, this is the Marburg virus outbreak in Rwanda. So far, six people have died from the outbreak, confirmed the health minister. Most victims were the healthcare workers in the hospital's intensive care unit. As per reports, 20 cases have been identified since the outbreak was confirmed on Friday.

What Is Marbug Virus?

With the fatality rate of 8% it is the same virus family as Ebola. The main carrier is from fruit bats which spreads to humans then through the contact of bodily fluids of infected individuals, it spreads to others.

Common Signs And Symptoms

The common signs and symptoms of the Marburg virus include fever, pain, diarrhoea, vomiting and in the case of extreme blood loss, death too can happen.

So far, there is no specific treatment or vaccine for the virus. However, treatments like drugs and immune therapy are being developed as per the World Health Organisation (WHO).

Call Of Action

Rwanda says that it has intensified its contact tracing, surveillance and testing to contain the spread. It has also tracked about 300 people who had come into contact with individuals affected by the Marburg virus.

The health minister has urged people to stay vigilant and avoid any physical contact and to wash their hands with clean water, soap or sanitiser and report any suspected case.

As of now, most of the cases have spread to the capital in Kigali. In light of this, the US Embassy in the city has advised its employees to work remotely for the next week.

This is the first time Rwanda has confirmed for Marburg cases, before this, in 2023, Tanzania confirmed the outbreak, whereas three people had died of this in Uganda in 2017.

History Of Marburg

As per WHO, this virus kills half of the people it infects. In the previous outbreaks, it has killed between 24% to 88% of the patients.

The virus was first detected in 1976 after 31 people were infected, out of which 7 died in simultaneous outbreak in Marburg and Frankfurt in Germany, and Belgrade in Serbia.

The source was traced to African green monkeys who were imported from Uganda. However, other animals too are linked to the virus spread, including bats.

In the past, the virus outbreaks have happened in countries like Equatorial Guinea, Ghana, the Democratic Republic of the Congo, Kenya, South Africa, Uganda, and Zimbabwe. In 2005, this virus killed 300 people in Angola.

However, for the rest of the world, only two people have died from the virus in the rest of the world, with one of them being in Europe, and the other in the US. These both have been on expeditions to caves in Uganda.

In a serious caution to the public, Dr Uma Kumar, Head of Rheumatology at AIIMS New Delhi, has warned against using AI chatbots such as ChatGPT for medical self-diagnosis. As reported by Hindustan Times, she issued the warning while speaking to the media after a recent case at the institute exposed the risks of acting on automated health advice.

The concern followed an incident in which a patient developed severe internal bleeding after treating back pain based on suggestions generated by an AI chatbot. The patient consumed non-steroidal anti-inflammatory drugs without consulting a doctor or undergoing basic medical tests.

When AI Advice Turns Dangerous

According to doctors at AIIMS, the patient relied on an AI tool to manage persistent back pain instead of seeking clinical care. The chatbot recommended commonly used painkillers, which the patient purchased and took independently.

As Hindustan Times noted, the AI system had no access to the patient’s medical history or their risk of stomach and intestinal complications. What appeared to be a routine solution resulted in a life-threatening episode of internal bleeding.

Doctors say this reflects a growing pattern, where quick online answers are replacing medical evaluation, even for drugs that are widely available over the counter.

Why Medical Diagnosis Is Not Data Matching

Dr Kumar explained that medical diagnosis follows a structured process known as diagnosis by exclusion. Doctors rule out possible causes through examinations, laboratory tests, imaging, and patient history before deciding on treatment.

An AI model, however, works by identifying patterns in data. It cannot examine a patient, detect physical warning signs, or judge whether a symptom points to a deeper problem. In this case, proper investigations would likely have revealed a high risk of bleeding, a step that was entirely bypassed.

The Risk of Confident but Incorrect Guidance

Medical experts are increasingly concerned about what are often called AI hallucinations, where chatbots present information with confidence despite gaps or inaccuracies.

While platforms such as ChatGPT include disclaimers, their tone can appear authoritative, particularly to someone in pain. As highlighted by Hindustan Times, the recommendation to use NSAIDs was not unusual in general practice, but for this patient, it proved dangerous.

Without a doctor to check for contraindications or underlying conditions, even a common suggestion can lead to serious harm.

Doctors Call for Caution and Clearer Oversight

The incident has renewed debate over how AI platforms should handle health-related queries. AIIMS doctors are urging the public to treat online tools as sources of general information rather than personal treatment guides.

Experts believe AI can assist healthcare in limited roles, such as research support or administrative tasks, but should never replace professional diagnosis or supervision.

There are also calls for stronger public awareness and clearer regulation to prevent similar incidents. Doctors continue to stress that medical judgment, built on examination and evidence, cannot be replaced by algorithms.

The Delhi High Court has turned down a Japanese company’s attempt to secure a patent for a cancer detection technique that relies on nematodes, or roundworms, ruling that it falls under diagnostic processes that cannot be patented under Indian law, regardless of how novel or non-invasive it may be.

Hirotsu Bio Science approached the High Court after India’s Controller of Designs and Patents rejected its patent application in August 2023, stating that the invention did not meet the criteria laid out in the Patents Act, 1970. In a detailed 25-page judgment delivered on Saturday, Justice Tejas Karia reaffirmed Section 3(i) of the Act, which clearly bars the patenting of diagnostic methods.

What Is the Nematode-Based Cancer Detection Method?

The nematode-based cancer detection method is a research-stage technique that uses microscopic roundworms, known as nematodes, to detect the presence of cancer. These organisms possess a highly developed sense of smell, allowing them to pick up on specific chemical cues released by cancer cells in bodily samples such as urine, breath, or tissue, as per Science Direct.

Laboratory experiments have shown that certain nematodes tend to move towards samples taken from individuals with cancer while avoiding those from healthy people. The underlying idea is that cancer changes the body’s chemical profile, creating odour patterns that these worms can detect, sometimes even at an early stage.

Scientists have looked at this approach as a potentially affordable and non-invasive screening option. However, it remains a concept under study and has not yet been accepted as a reliable medical test or used in routine clinical care.

Delhi HC Upholds Patent Rejection of Nematode-Based Cancer Detection Method

At the centre of the case was a patent application titled “Cancer detection method using the sense of smell of nematode.” Nematodes, often referred to as roundworms, are among the most widespread life forms on the planet and can be found in environments ranging from soil to living organisms.

The Japanese company aimed to patent a technology based on the biological response of Caenorhabditis elegans, a species of nematode recognised for its advanced olfactory abilities.

The firm explained that its invention relies on the chemotaxis of these worms, meaning their tendency to move towards or away from certain scents, which would serve as a biological signal for the presence of cancer.

According to the company, the nematodes showed avoidance behaviour when exposed to urine from healthy individuals, while being drawn towards urine samples from cancer patients. It claimed the method demonstrated complete accuracy during testing and could detect several cancers, including gastric, colorectal, and pancreatic cancers, even at very early stages.

Is This Process Patentable in India?

The main legal question was whether the method qualified as a non-patentable “diagnostic process” under Section 3(i) of the Patents Act, 1970. This provision excludes from patent protection any process related to medicinal, surgical, curative, preventive, diagnostic, or therapeutic treatment of humans.

Hirotsu Bio Science Inc challenged the rejection by the Controller of Designs and Patents in the High Court, arguing that their invention should be seen as a “detection” method rather than a “diagnostic” one. The company maintained that the process was carried out entirely in a laboratory setting, using samples such as urine or tissue, and did not involve any direct medical procedure or clinical decision-making on the human body.

What Is Salmonella?

Apart from this, other symptoms include:

• Fever
• Nausea
• Vomiting
• Chills
• Headache
• Blood in the stool

Most people develop symptoms within 8 to 72 hours after exposure while most healthy people recover within a few days to a week without specific treatment. However, in some cases, diarrhea can cause severe dehydration and requires prompt medical attention.

While anyone can contract salmonella, children younger than five, elderly and people with weakened immune systems are more likely to develop severe infections.

Is Salmonella Life-Threatening?

Life-threatening complications may develop if the infection spreads beyond the intestines to other organs. The risk of getting salmonella infection is higher with travel to countries without clean drinking water and proper sewage disposal.

While most people do not require medical attention for salmonella infection, those at high risk may need a health care provider if the infection lasts more than a few days, is associated with high fever or bloody stools and appears to be causing dehydration, with signs such as such as urinating less than usual, dark-colored urine as well as having a dry mouth and tongue.
