An experimental treatment happens to be the solution to delay Alzheimer's symptoms in some people. These people are the ones who are genetically destined to get the disease in their 40s or 50s. These new findings form ongoing research has now been caught up in Trump administration funding delas. The early results of the study has been published on Wednesday and the participants too are worried that politics could cut their access to a possible lifeline.

One of the participants had said, "It is still a study but it has given me an extension to my life that I never banked on having." The participant is named Jake Henrichs, form New York City, who is 50 years old. He is one of them to be treated in that study for more than a decade now and has remained symptom-free despite inheriting an Alzheimer's-causing gene that had killed his father and brother around the same age.

Slowing Down The Symptoms

Two drugs which can modestly slow down early-stage Alzheimer's are sold in the United States. These drugs clear the brain of one of its hallmarks, a sticky gunk-like part called the amyloid. However, there have not been any hints that removing amyloid far earlier, way many years before the first symptoms appear, may postpone the disease.

How Was The Research Conducted?

The research is led by Washington University in St Louis, which involved families that passed down rare gene mutation as participants. This meant it was almost guaranteed that they will develop symptoms at the same age their affected relatives did.

The new findings is based on a subset of 22 participants who received amyloid-removing drugs the longest, on average eight years. Long-term amyloid removal cut in half their risk of symptom onset. The study is published in the journal Lancet Neurology.

Washington University's Dr Randall Bateman, who directs the Dominantly Inherited Alzheimer's Network of studies involving families with these rare genes says, "What we want to determine over the next five years is how strong is the protection. Will they ever get the symptoms of Alzheimer’s disease if we keep treating them?”

The researchers before though did not know what exactly caused Alzheimer's which affects nearly 7 million Americans, most of them in their later life. However, it is clear that these silent changes occur in the brain at least two decades before the first symptom shows up. The big contributor. At some point amyloid buildup can trigger a protein named tau that then starts to kill neurons, which can lead to cognitive decline.

Researchers are now thus studying the Tau-fighting drugs and are looking into other factors, like inflammation, brain's immune cells and certain virus.

The National Institute of Health (NIH) has expanded its focus as researchers have found more reasons for Alzheimer's. In 2013, the NIH's National Institute on Aging funded 14 trials of possible Alzheimer's drugs over a third targeting amyloid. By last fall, there were 68 drugs and 18% of them target amyloid. However, there are scientists too who think that amyloid is not everything and their is way more in the brain tissue, immune cells, and more which can be studied.

Ebola Resurfaces In Eastern DR Congo In 17th Outbreak, Claims 65 Lives: All You Need To Know

Updated May 15, 2026 | 10:00 PM IST

SummaryWhile tests are being carried out to identify the strain of the virus, early indications suggest the strain is not the Zaire variant, which has been responsible for several previous outbreaks in the country, the health officials said.

Even as the world is still grappling with the news of a hantavirus and two separate norovirus outbreaks, the Africa Centres for Disease Control and Prevention (Africa CDC) today confirmed that the Ebola virus has resurfaced in eastern Democratic Republic of the Congo for the 17th time.

In a statement, the Africa CDC reported that there are 246 suspected cases and 65 deaths, mainly in the mining areas of Mongwalu and Rwampara, about 100 kilometers north of the provincial capital, Bunia.

While tests are being carried out to identify the strain of the virus, early indications suggest the strain is not the Zaire variant, which has been responsible for several previous outbreaks in the country, the health officials said.

The Ebola Zaire strain was prominent in Congo’s past outbreaks, including the 2018 to 2020 outbreak in the eastern region that killed more than 1,000 people.

Ebola: 17th outbreak in DR Congo

Ebola was first discovered in 1976 in the DR Congo. This is the 17th outbreak of the deadly viral disease in the country.

As per preliminary tests conducted at the Institut National de Recherche Biomédicale (INRB) in the country's capital, Kinshasa, the Ebola virus has been detected in 13 of 20 samples analysed, following consultations with DR Congo's Ministry of Health and National Public Institute.

Of the 65 deaths, four were reported among lab-confirmed cases, Africa CDC said.

Additional suspected cases have also been reported in Ituri's provincial capital, Bunia, a densely populated urban centre near the borders with Uganda and South Sudan, raising fears of regional transmission.

All affected communities and at-risk areas have been advised to follow guidelines from the national health authorities.

What Is Ebola Virus Disease?

As per the WHO, Ebola virus disease (EVD) is a rare but severe illness in humans and is often fatal.

People can get infected with the virus if they touch an infected animal when preparing food, or touch body fluids of an infected person, such as saliva, urine, feces, or semen, or things that have body fluids of an infected person, like clothes or sheets.

How Does Transmission Work?

Ebola enters the body through cuts in the skin or when one touches their eyes, nose, or mouth. Early symptoms include fever, fatigue, and headache.

It is a highly infectious and transmissible disease; in fact, there have been cases of healthcare workers who have frequently been infected while treating patients with suspected or confirmed Ebola. This occurs through close contact with patients when infection control precautions are not practiced strictly.

Cases of people conducting burial ceremonies, involving direct contact with the body of the deceased, can lead to the transmission of Ebola. Even after the long suffering and recovery, there is a possibility of sexual transmission. Pregnant women who get acute Ebola and recover may still carry the virus in their breastmilk or in pregnancy-related fluids and tissues.

Symptoms include:

  • feeling tired
  • headache
  • muscle and joint pain
  • eye pain and vision problems
  • weight gain
  • belly pain and loss of appetite
  • hair loss and skin problems
  • trouble sleeping
  • memory loss
  • hearing loss
  • depression and anxiety.

Is There Any Vaccine for Ebola?

According to the WHO, there are two vaccines against the Ebola virus. But both the Merck-developed Ervebo vaccine, administered in one dose, and Johnson & Johnson-developed Zabdeno and Mvabea vaccine, administered in a two-dose regimen, target Zaire ebolavirus.

The Ervebo vaccine is recommended for use in outbreak settings and is currently the only vaccine available in the global stockpile.

More Americans Exposed To Hantavirus; 41 Under Monitoring, Says CDC

Updated May 15, 2026 | 06:06 PM IST

SummaryThe CDC said its monitoring 16 people who were not on the MV Hondius cruise ship but were passengers on an April 25 flight to Johannesburg and were exposed to someone known to have been infected

The hantavirus outbreak may no longer be confined to the luxury Dutch cruise ship MV Hondius, with health officials now assessing the possibility of wider exposure. Officials at the US Centers for Disease Control and Prevention (CDC) said that although no cases have been reported in the US so far, the agency is monitoring 41 people for possible exposure.

The 41 includes the 18 people evacuated from the hantavirus-hit ship from Spain’s Canary Islands.

Notably, of the 18 passengers evacuated, two were carried in the plane's biocontainment units out of an abundance of caution — one who tested positive and another considered a suspected case. They were quarantined at a special facility in Nebraska. The remaining 16 are being quarantined in Omaha and Atlanta.

Speaking to CNN from a biocontainment unit at the University of Nebraska Medical Center in Omaha, Dr. Stephen Kornfeld of Oregon said he “feels wonderful” and is not experiencing symptoms.

Spanish officials confirmed that after initially testing positive for hantavirus, Dr. Kornfeld has since tested negative twice for the disease, meaning no Americans currently have the illness, Forbes reported.

CDC Monitoring More People

However, an additional 16 people are being monitored by the CDC.

The new individuals were not on the cruise ship but were passengers on an April 25 flight to Johannesburg and were exposed to someone known to have been infected, said Dr. David Fitter, who is leading the CDC response to the outbreak, according to The New York Times.

Seven other passengers from the cruise ship had disembarked on April 24 in St. Helena, an island in the Atlantic Ocean, returned to the US on commercial flights, and are being monitored by state health departments.

As of May 14, there were no confirmed hantavirus cases in the United States, Dr. Fitter said.

“Our job is to ensure that we are monitoring and in contact with anybody that might have been on the flight this person had taken,” Dr. Fitter told reporters. The agency is “monitoring all Americans that potentially would have been exposed, whether in the US or abroad, and we have been in contact with them,” he said.

Hantavirus Outbreak: 11 Cases And 3 Deaths Reported

According to the World Health Organization (WHO), 11 people have been affected by the rat-borne virus so far, of whom three have died.

A Dutch couple is believed to have first been exposed to the virus while visiting a birdwatching site in Argentina.

The WHO has confirmed that the Andes strain of hantavirus — the only strain known to spread from person to person — is behind the outbreak.

While all passengers onboard the cruise have been taken care of by health authorities, the virus’ long incubation period remains a serious concern. This means that even asymptomatic individuals could potentially become infectious 6-8 weeks later.

WHO Guidelines On Hantavirus Exposure

The WHO recommends that people exposed to hantavirus should be:

  • Monitored actively at a specified quarantine facility
  • Monitored at home for 42 days from the last exposure
Anyone who becomes symptomatic should be isolated and treated immediately.

While stressing that the risk to the wider public remains low, the UKHSA confirmed that one case has been identified as Meningitis B (MenB), while further testing is ongoing.

The latest infections come after a small number of meningitis B cases were reported in the Weymouth region in April, followed by a major outbreak in Kent in March that affected more than 30 people and led to the deaths of a sixth-form pupil and a university student.

What’s The Meningitis Situation In Reading?

The young person who died attended The Henley College, according to a local GP surgery.

Authorities are reportedly sharing information about the infection with students and parents at affected schools. The other two cases are believed to be linked to schools in the Reading area. But the officials are yet to disclose the exact link.

Health officials said close contacts of the infected individuals are being offered antibiotics as a precaution.

GP surgery, the Hart Surgery, based in Henley-on-Thames, stated that it was in contact with the UKHSA due to the college’s location, adding that the agency was “actively contacting those who may be at risk due to a close association with the student involved.”

However, it said anyone whom the UKHSA has not contacted does not require treatment, and students and staff can continue attending the sixth-form college as usual.

“The number of confirmed cases is very low, so there are currently no plans for a local emergency meningitis vaccination programme,” it added.

What Is Meningitis?

Meningitis is a serious medical condition that affects the protective membranes covering the brain and spinal cord, known as the meninges. Fever is often considered one of the classic symptoms, although it may not always be present.

Understanding the symptoms, causes, and treatment options is important for early diagnosis and timely medical care.

“Anyone can get meningitis, and around 300 to 400 cases of meningococcal disease are diagnosed in England every year. It is most common in babies, young children, teenagers, and young adults," said Dr Rachel Mearkle, a consultant in health protection at the UKHSA.

“It needs to be treated quickly, so it is important to know the signs and symptoms. They can appear in any order and may not all be present, so seek rapid medical attention if there is ever any concern," she added.

The expert noted that "meningococcal meningitis requires very close contact to spread, and large outbreaks such as the one recently seen in Kent are thankfully rare."

“Meningococcal disease does not spread easily, and the risk to the wider public remains low.”

Symptoms Of Meningitis

Health officials urged the public to remain alert to the warning signs of meningococcal meningitis. Common symptoms include:

  • Rash
  • Headache
  • Neck stiffness
  • Fever
  • Drowsiness
  • Nausea or vomiting
  • Increased sensitivity to light

“If the disease is suspected, immediate medical attention should be sought, as it can progress rapidly,” the officials said. While antibiotics provide the quickest short-term protection, vaccines offer longer-term protection.
