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.

In an alarming report, Anthropic, an artificial intelligence safety and research company and developer of the Claude family of large language models, said it blocked multiple accounts that used its AI models in ways that could support the development of biological weapons.
In a report published Thursday, the San Francisco-based AI company described biological misuse as one of the “most serious risks” to increasingly capable AI models. The report covers attempts to misuse Claude between December 2025 and August 2026, including activity involving biology, weapons, cyberattacks, influence operations and surveillance.
It details five cases involving potentially concerning biological research, including chikungunya gain-of-function research, avian influenza, orthopoxviruses, venoms and toxins.
“We're publishing our most detailed threat intelligence report to date. It covers how people tried to misuse Claude—for cyberattacks, influence operations, surveillance, biology, and building weapons—and how we found and stopped them,” Anthropic said on X.
Anthropic identified about 35 potentially concerning “research efforts” over 30 days. It could not determine whether users “intended harm” or were conducting legitimate research.
Five cases involved users circumventing safeguards or regional restrictions:
“We disrupted every operation in the report, and used the lessons from them to strengthen our safeguards,” Anthropic said.
The company said it also shared information with authorities and other AI companies where appropriate.
“These cases are not typical: we’re highlighting some of the most sophisticated misuse we’ve seen,” it said.
The report comes as former Anthropic employee Jacob Coxon resigned this week, stating on X that “the people building AI earnestly believe that it could kill us all by the end of the decade.”
The 27-year-old AI researcher said it could hack critical infrastructure — or build “extinction-level bioweapons.”
“There’s a lot of ways that the AI could actuate itself in the world,” he said. “If you extrapolate into the future, the level of capabilities of these AIs … they could cause extreme havoc,” Coxon later told CNN.
In July, nearly 1,400 AI company employees signed an open letter urging the US government to regulate the technology and slow its development to ensure its safety.
OpenAI Chief Scientist Jakub Pachocki also warned this week that AI capabilities are advancing faster than researchers’ ability to reliably monitor and control them.
Dr Ashish K. Jha, physician, scientist and biosecurity expert, said the Anthropic cases show how AI could lower some barriers to biological research.
“We are sleepwalking into a potentially huge disaster. And it amazes me how little attention it is getting,” Jha said on X.
“Anthropic just published five case studies today of people using Claude in ways that could have helped develop biological weapons. They banned the accounts, traced the networks, and told other AI labs and governments what they found.”
Jha said the barriers that once made biological weapons difficult to develop included “deep expertise, advanced equipment, years of specialized training.” “Those barriers are dissolving. Rapidly,” he said.
Jha also pointed to a case in which Claude blocked a request, after which the operator built a system to route it to a more permissive model.
“In a world of lots of open access models that are getting quite good, this will keep happening,” he said.

The US is seeing a summer surge in COVID-19 infections, with 35 states reporting rising cases, according to the latest update from the Centers for Disease Control and Prevention (CDC).
The September 9 update said cases are declining in eight states and unchanged in seven. COVID-related emergency department visits remain low, while the probability of the epidemic growing is 73%, as per CDC. The cases are expected to grow in the coming weeks.
COVID activity is elevated nationally, but hospitalizations remain low, with the highest rates among infants and adults aged 65 and older.
California, Nevada and Texas have the highest wastewater levels of COVID among US states, according to CDC data.
A south Texas school district reportedly closed for two days in August due to the spread of COVID, citing the need to “protect the health and safety” of students and staff.
Experts say the summer wave is not unexpected. SARS-CoV-2 spreads year-round but has developed a seasonal pattern in the US.
“We’ve had two waves (every year). One in the middle to late summer, and the other during the winter,” Dr. William Schaffner, an infectious disease specialist at Vanderbilt University Medical Center, toldTODAY.com.
“We’re expecting transmission to peak about a week into September,” said Michael Hoerger, assistant professor at Tulane University School of Medicine was also quoted as saying.
With temperatures dropping and children returning to school, opportunities for transmission could increase.
“We need to be very cautious,” Schaffner added.
WastewaterSCAN data is detecting XFG, LF.7, NB.1.8.1 and BA.3.2. XFG.1.1 and its sublineages accounted for nearly half of US cases in July, according to CDC data. BA.3.2, or Cicada, accounts for less than 10% of cases and has not taken off in the US.
Although there is no new variant, that does not mean COVID-19 cannot cause severe disease, experts noted.
Symptoms remain similar to those caused by other Omicron strains and usually appear two to 14 days after exposure.
Common symptoms include:
Many people are reporting an intense sore throat, according to Thomas Russo, professor and chief of infectious diseases at the University at Buffalo in New York.
“Some people feel like it’s the worst sore throat ever, like razor blades in the throat. But it can be more mild in others," he was quoted as saying to Prevention.com
Nausea and diarrhoea can also occur alongside respiratory symptoms.
While for majority COVID will be a flu-like illness, for some it can cause more severe illness like pneumonia and shortness of breath.
Adults over 65, infants, people with weakened immune systems or underlying conditions, and those who have never received a COVID vaccine face a higher risk of severe illness or hospitalization, says Schaffner.
In May, the US FDA voted to recommend an updated 2026-2027 COVID vaccine targeting XFG. On August 28, the FDA approved monovalent 2026-2027 COVID vaccines from Moderna, Pfizer-BioNTech and Novavax-Sanofi.
The updated vaccines are expected to roll out at pharmacies, clinics and hospitals in September.

Obstructive sleep apnea (OSA) affects nearly 1 billion adults worldwide and is linked to cardiovascular disease, stroke and increased mortality.
Eli Lilly’s GLP-1 drugs Mounjaro and Zepbound, which contain tirzepatide, have shown promise in treating sleep apnea in a new review.
While continuous positive airway pressure (CPAP), which uses air pressure to keep the airway open during sleep, remains the standard treatment, some people struggle to use it long term. Adherence rates of 30% to 60% limit its effectiveness at the population level. The review showed that GLP-1 medications may be a potential complementary therapy alongside CPAP.
Researchers from the University of Pittsburgh Medical Center, Pennsylvania, reviewed existing evidence on GLP-1 receptor agonists (GLP-1 RAs) for OSA.
Six meta-analyses found consistent reductions in the apnea-hypopnea index (AHI), ranging from 5.7 to 21.9 fewer events per hour.
The Phase 3 SURMOUNT-OSA trials found that tirzepatide reduced AHI by 20 to 24 events per hour compared with placebo. Between 42% and 50% of patients achieved disease remission.
Weight loss is the main established mechanism. GLP-1 RAs may reduce tongue fat and parapharyngel fat, which contribute to airway collapse.
Researchers also identified potential weight-independent effects involving chemosensitivity, leptin pathways and NLRP3 inflammasome suppression, although these mechanisms remain under investigation.
GLP-1 RAs did not match CPAP efficacy, with approximately 22 versus 31 fewer AHI events per hour. Cardiovascular benefits remain unproven, and weight regain commonly occurs after treatment stops.
The researchers said GLP-1 drugs are best positioned as complementary therapy alongside CPAP and other treatments.
The drugs may be appropriate for people with a BMI above 30 who are unable to tolerate CPAP or have obesity-related comorbidities. They are less likely to benefit people without obesity or those with primarily anatomical airway obstruction.
“This review suggests that GLP-1 RAs offer otolaryngologists a disease-modifying adjunct for obesity-related OSA that is best positioned as complementary therapy alongside CPAP, preoperative optimization before upper airway surgery, or potentially to expand hypoglossal nerve stimulator candidacy,” said the researchers in the paper published in JAMA Otolaryngology–Head & Neck Surgery.
OSA occurs when the airway becomes blocked during sleep, causing breathing to repeatedly stop and restart. These interruptions can occur five to 100 times an hour and can lower oxygen levels and disrupt sleep.
In OSA, the airways become partially or completely blocked when the muscles in the head relax during sleep. This can cause soft tissue to obstruct the windpipe, making it difficult for air to pass through.
While asleep, the chest muscles may work harder than usual to reopen the airway. This can cause jerks, deep gasps and repeated disruptions to sleep.
Common symptoms include:
People may not notice these symptoms themselves, but a partner or family member may observe them.
Measures that may help prevent or manage sleep apnea include:
