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.
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.
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).
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.
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.

A fast-spreading new flu variant driving a sharp rise in infections across the state is bringing with it symptoms that differ from what many people usually associate with influenza.
With flu activity now classified as “very high” in Illinois, health experts say a mutated and highly contagious strain known as subclade K is changing how the illness shows up, particularly when it comes to fever patterns. One of the biggest differences doctors are seeing is how intense and long-lasting fevers have become, especially among children.
“There’s more fever with the flu this year than people are used to,” said Dr. Mark Loafman, chair of Family and Community Medicine at Cook County Health, speaking to NBC Chicago. “The fever can last five to seven days, and that’s concerning. You feel sick, you don’t feel like you’re improving, and that can be worrying.”
Adding to the concern, Dr. Juanita Mora, national spokesperson for the American Lung Association, as per NBC News, said some patients are finding that common fever-reducing medicines such as Tylenol or Motrin are not working as effectively. “This strain is causing very high fevers,” Mora said. “There’s also a severe cough that just doesn’t go away, a lot of phlegm, vomiting, diarrhoea, and significant joint and muscle pain.”
Vomiting has never been among the most typical flu symptoms, though it does occur more often in children. What doctors are now noticing with this strain is an increase in gastrointestinal symptoms among adults as well.
“Kids with the flu often experience nausea or vomiting,” Loafman explained. “Adults usually don’t as much, but we are hearing more reports of GI symptoms in adults who have this subclade K strain.” Because of this, he said flu should not be ruled out just because stomach symptoms are present.
“If you have GI issues along with body aches, fever, and respiratory symptoms, flu is still very much a possibility,” he said, adding that at-home flu tests can be useful if someone suspects they are infected.
Warnings have already been issued by the Illinois Department of Public Health and several county health departments as flu-related hospital admissions and positive test results continue to climb.
According to the latest state update released Monday, flu activity has reached “very high” levels, the most severe category used by the CDC to track respiratory illness trends.
Health officials say most emergency room visits and hospital admissions related to respiratory illness are currently being driven by flu cases.
Flu symptoms typically appear one to four days after exposure, according to the Cleveland Clinic.
The CDC lists the following common symptoms:
Not everyone with the flu will develop a fever. However, health officials note that gastrointestinal symptoms are being reported more often in adults with the new strain.
Because this variant is linked to higher and longer-lasting fevers, Mora said it is crucial to recognise when medical care is needed.
“High fevers that don’t come down are one warning sign,” she said. “Another is trouble breathing, including wheezing, chest muscle use, or a cough that won’t stop. And dehydration is a major concern, especially if someone is barely eating or drinking.”
The CDC outlines different warning signs for children and adults.
In children:
In adults:
According to the CDC, people can spread the flu starting about one day before symptoms appear and up to seven days afterward. Most people are most contagious around three days into the illness. Young children and those with weakened immune systems may remain contagious longer.
“It’s usually about five to seven days from when symptoms start before people stop shedding high levels of the virus,” Loafman said. “Ten days is very cautious, but not always necessary.”
He advised masking around vulnerable people during the first week, practicing good hand hygiene, and staying home whenever possible. “If you can stay in, stay home,” he said, as per NBC News.

Environmental and public health scientists have begun warning against the dangers of having free living amoeba in water systems that are capable of triggering severe diseases in humans.
In a recent perspective article published in Biocontaminant, the researchers noted that climate change, deteriorating water infrastructure and limited systems for monitoring and detection are the key factors that have allowed these pathogens to spread and persist.
Corresponding author Longfei Shu of Sun Yat sen University explained: "What makes these organisms particularly dangerous is their ability to survive conditions that kill many other microbes.
"They can tolerate high temperatures, strong disinfectants like chlorine and even live inside water distribution systems that people assume are safe."
The scientists also emphasized that not only can amoebae spread illnesses on its own, it can also act as hidden carriers for other harmful microbes.
By sheltering bacteria and viruses inside their cells, amoeba these unicelled organisms protect these pathogens from disinfection and help them persist and spread in drinking water systems. This so-called Trojan horse effect may also contribute to the spread of antibiotic resistance among humans.
Amoeba are single-celled organisms that naturally live in soil and water. Most species do not cause harm yet some can prove to be fatal.
Some of the diseases caused by this kind of bacteria include Amebiasis (Amoebic Dysentery), an intestinal infection by Entamoeba histolytica, causing diarrhea, cramps and potential liver abscesses as well as Primary Amoebic Meningoencephalitis (PAM) from Naegleria fowleri, a rare but nearly always fatal brain infection from contaminated water entering the nose.
Effects of amoeba-caused infections range from intestinal issues (liver abscesses, anemia, peritonitis) to severe neurological damage (coma, seizures, death) from brain-eating types, with Acanthamoeba causing eye infections (keratitis).
Experts recommend thoroughly washing your hands after toilet use and before handling food, drinking clean water especially in unsanitary conditions and avoiding getting water up your nose in warm freshwater to prevent such infections.
This comes days after the recent Indore sewage water controversy which has claimed the lives 10 people and left over 1,400 people hospitalized, according to Indore Mayor Pushyamitra Bhargava.
However, locals claim that the outbreak has instead caused the death of 17 residents, including a six-month-child. The situation has also left Parvati Bai, 67, with kidney failure, a brain stroke and symptoms of Guillain-Barré Syndrome, or GBS.
GBS is a rare condition where your immune system attacks the nervous system and can cause paralysis as well as death, in certain cases.
The outbreak occurred due to lapses in civic infrastructure. Investigation revealed that a toilet constructed directly above a main drinking pipeline near a police outpost, without a mandatory safety tank resulted in the sewage mixing with drinking water.

The US Food and Drug Administration has approved the use of a blood test which can help diagnose Alzheimer’s disease in adults aged 55 and above.
The blood test, known as Lumipulse, can detect amyloid plaques associated with Alzheimer’s disease and has proven to be a “less invasive option” that “reduces reliance on PET scans and increases diagnosis accessibility.”
FDA Commissioner Martin A. Makary said of the landmark decision, "Alzheimer’s disease impacts too many people, more than breast cancer and prostate cancer combined.
"Knowing that 10% of people aged 65 and older have Alzheimer's, and that by 2050 that number is expected to double, I am hopeful that new medical products such as this one will help patients."
It remains unclear when this test will be available for commercial use across the world.
About 8.8 million Indians aged 60 and above are estimated to being living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.
Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.
Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.
Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.
While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.
Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.
There is no cure to this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.
As explained by Dr Abhay Moghekar, an associate professor of neurology at Johns Hopkins University School of Medicine, who helped study and evaluate the test for FDA approval, "If this test is positive, there’s a greater than 90% chance that you have amyloid plaque in your brain.
"Getting a blood test is gonna be far easier, quicker and cheaper,” he said. “It’s going to allow early access to therapy, so it is going to revolutionize care of patients with dementia."
However, the federal agency also noted certain limitations associated with the test such as it can only be used for patients 55 and older who are already experiencing memory problems.
The FDA also cautions that the test is not intended as a standalone diagnostic tool for Alzheimer’s and results should be interpreted based on the patient’s medical history and other assessments, such as cognitive testing.
