Japan could become one of the first countries in the world to end the HIV epidemic, says the president of Gilead Sciences Japan, Kennet Brysting. The idea for now could seem a little too ambitious, but it is not entirely unrealistic, given that the availability of medicines that can prevent transmission of HIV. Drugs are not the cure, but control over the spread of virus to the point where the disease is no longer a major public health threat.
Gilead's have two key drugs, Truvada and lenacapavir. These two are playing a crucial role in prevention. Truvada is taken as a daily pill, while lenacapavir requires two injections per year. It can make the virus undetectable in infected individuals and prevent transmission to those who are not infected yet. In trials, lenacapavir showed 100% efficacy in preventing HIV infections. This is why it is describe as "almost a vaccine".
In 2024, Japan also approved Truvada for HIV prevention, but the country has yet to approve lenacapavir for the same. Until now, people in Japan had been importing generic versions of Truvada or purchasing it from clinics that source it from overseas.
Up until now, Japan reported around 25,000 HIV infections, whereas 669 new cases were reported in 2023. For seven consecutive years, the number of new infections remained under 1,000. The downward trend thus shows that the virus has been controlled, however, getting to zero new infections remains the ultimate goal.
Brysting too acknowledged that simply having effective drug is not enough. What is important is to have a proper implementation, access and healthcare support to make sure that these treatments are widely available and effective.
The biggest challenges is testing rates. There is a need to increase testing rates. At this very moment, around 86% people infective with Japan have been tested, but the goal is to increase it up to 95%, with an ideal goal of 100%. Without widespread testing, many infected people may not even know that they are infected and it could transmit the virus.
Another measure issue is the cost of preventative medication. While Japan's health insurance covers treatments for diseases, it does not cover preventative drugs. Those who purchase Truvada for prevention, pay around $470 per month. Some clinics in Tokyo offer generic alternatives too, which is cheaper, but they are not ideal.
Brysting expressed concern that individuals importing medications might not be consulting doctors regularly, which is essential for monitoring HIV status and overall health. Truvada users need to be tested for HIV initially and every three months, along with screenings for other infections and kidney function checks. Without proper medical supervision, there is a risk of misuse and inadequate protection.
Gilead is in discussions with Japanese authorities to improve access and insurance coverage for Truvada, and progress is being made. Japan has shown efficiency in approving critical medicines, as seen during the COVID-19 pandemic when Gilead’s remdesivir was approved in just three days.
Gilead at this moment is not only focused on HIV and hepatitis C, but also expanding into oncology with innovative treatments like CAR-T cell therapy, which strengthens a patient's immune system to fight cancer.
However, Japan’s strict approval processes can slow down drug availability. Phase 3 clinical trials often need to be conducted within the country, and Japan tends to approve medicines much later than other regions. For instance, Truvada was approved for prevention in Japan 12 years after the U.S. and nearly 20 years after its approval for treatment. inancial factors also play a role. The Japanese government adjusts drug prices annually, often reducing them, which can make long-term investment challenging for pharmaceutical companies.

A new study has found out what researchers call the strongest evidence yet that long COVID may directly injure the brain's dopamine system, offering an explanation for symptoms like fatigue, brain fog, poor memory, slowed movement, and lack of motivation that persist long after the initial infection.
While it has been a long time since the end of the COVID pandemic, its effects continue to linger even today. Several patients who contracted COVID continue to suffer. This is known as long COVID.
Dopamine is a neurotransmitter that plays a key role in movement, motivation, learning, reward, and memory.
The study, conducted by researchers at the Centre for Addiction and Mental Health (CAMH) in Toronto and published in the journal eBioMedicine, used advanced positron emission tomography (PET) scans to examine the brains of people living with long COVID.
They found significantly lower levels of a marker that reflects the health of dopamine-producing systems across key regions of the brain compared with healthy participants.
The researchers discovered that reductions in dopamine markers were closely tied to patients' symptoms. Lower dopamine activity in one region of the brain, known as the ventral striatum, was associated with a greater loss of motivation.
Reduced dopamine markers in the dorsal putamen were linked to slower movement, while declines in the caudate putamen correlated with memory problems.
"Our findings provide compelling evidence that long COVID involves the loss of dopamine-releasing neurons," said senior author Dr. Jeffrey Meyer. "We know that inflammation can injure dopamine neurons. While our earlier research showed high levels of inflammation in those regions, this study provides direct evidence that the dopamine neuron marker is reduced in the same regions, and that this loss correlates with patients' symptoms."
Long COVID affects an estimated five percent of the global population and continues to leave millions struggling with persistent symptoms for months or even years after recovering from the initial infection.
Despite its widespread impact, there are currently no evidence-based treatments specifically approved for the condition because its underlying biological mechanisms remain poorly understood.
According to Dr. Meyer, the findings could mark a turning point in long COVID research. "These results indicate that long COVID is, at least in part, a disorder of the brain's dopamine system," he said. "This suggests that repurposing medications that augment the function of dopamine-releasing neurons, including dopamine precursors and inhibitors of dopamine metabolism, could be a promising approach."
The research also provides validation for many patients who have struggled to have their symptoms recognized.
"For five years I have been seeking answers on what happened to me after I contracted COVID in 2021," said Susan Deuville, a lived-experience research advisor involved in the project. "It was a crushing loss of the life I had and the person I was before. The research of Dr. Meyer brings hope. It also validates what long COVID sufferers have always known, long COVID is real and the effects are devastating."
The team plans to launch a clinical trial in the coming months to test whether existing medications that enhance dopamine function can improve memory, fatigue, and motivation in people with long COVID.

One of New York City's most iconic cultural landmarks has unexpectedly become part of an ongoing disease investigation.
Amid the current Legionnaires' disease outbreak on Manhattan's Upper East Side, the officials flagged Solomon R. Guggenheim Museum after Legionella bacteria was detected in its rooftop cooling tower.
While the discovery has raised concerns, authorities stress that the museum has not been identified as the source of the outbreak.
The investigation began after a cluster of Legionnaires' disease cases were reported in the Upper East Side neighborhoods of Carnegie Hill and Yorkville.
Since then, the New York City Department of Health has expanded testing across the area, identifying 31 buildings with cooling towers that tested positive for Legionella bacteria. The world-famous museum is among those properties.
Despite the positive test, officials emphasize that detecting Legionella in a cooling tower does not mean the building caused the outbreak.
Further laboratory testing is required to determine whether the bacteria found in a particular cooling tower genetically match the strain infecting patients, a process that can take several weeks.

The museum acted quickly after receiving the test results, disinfecting and cleaning its cooling tower in accordance with city regulations.
Health officials said the building does not pose an ongoing risk to visitors, and the museum has remained open to the public.
A Guggenheim spokesperson said, “The city has confirmed that there is no additional action needed at this time, and this poses no risk to anyone inside the building,” adding that the museum conducts monthly cooling tower testing and treatment.
The spokesperson added, “The safety of our staff and the public are the utmost priority, and we are continuing to follow all city guidelines.”
As per NY Post, at least 46 people have been diagnosed with Legionnaires, including 22 who remain hospitalized. New York City Health Commissioner Alister Martin said the bacteria were detected in 31 towers and 19 had already been disinfected.
Martin said, “What we have in front of us is 160 cooling towers across this region that we are looking at, and we are not waiting.”
Cooling towers have been recognised as one of the most common sources of large Legionnaires' disease outbreaks as they contain warm water that can allow Legionella bacteria to thrive.
Fans in these systems can release fine mists into the surrounding air, exposing people nearby if the water becomes contaminated. This is why New York City requires routine inspection, testing and disinfection of cooling towers, regulations that were strengthened following previous outbreaks in the Bronx and Harlem.

Besides Guggenheim Museum, here are the other prominent buildings that are currently compromised due to Legionnaires' Disease:
Symptoms typically develop two to 14 days after exposure and include fever, cough, muscle aches, chills, shortness of breath and, in severe cases, pneumonia.
Health officials continue to investigate the Upper East Side cluster and are urging anyone who visited the affected area and develops flu-like symptoms or pneumonia to seek medical attention promptly.

Martha Lillard, the last person in the United States to rely on an iron lung for breathing, passed away, making the end of a chapter in American medical history that goes back to the devastating polio epidemics of the 20th century.
According to her kin, Martha Lillard, 78, died on June 26, 2026, at her home in Shawnee, Oklahoma.
She had spent close to 73 years living with the effects of paralytic polio, a disease that permanently damaged the muscles needed for breathing, leaving her dependent on an iron lung, a medical device that has now become obsolete.
According to reports, chronic pulmonary failure and post-polio syndrome were listed among the causes of her death. Her family also said she experienced long COVID, which further worsened her lung function, increasing the amount of time she needed to spend inside the iron lung.
Lillard contracted polio in 1953 when she was just five years old, during one of the worst outbreaks in U.S. history.
Before effective vaccines became available, the virus infected tens of thousands of Americans each year. While many people recovered, some developed paralytic polio, in which the virus attacks the nervous system, leading to paralysis and, in extreme cases, respiratory failure.
Doctors placed Lillard inside an iron lung, a large cylindrical machine that uses negative air pressure to help patients breathe by expanding and contracting the chest.
Although hospitals gradually replaced iron lungs with ventilators in the 1960s, Lillard continued using the ancient device because it proved to be the most effective method of respiratory support for her.
Her family said maintaining the iron lung became increasingly challenging as replacement parts and technicians familiar with the obsolete technology became hard to find. Still, Lillard continued using the machine well into her seventies.
Despite spending most of her life inside the machine, Lillard refused to let it define her. According to her family members and previous interviews, she attended school from home through an intercom system connected to her classroom.
She also became fond of painting, writing poetry, composing music, and caring for rescued animals. She also volunteered with community organizations, including the Humane Society.
Lillard's passing comes more than 70 years after Jonas Salk's polio vaccine was introduced in 1955, followed by Albert Sabin's oral vaccine in the early 1960s. Widespread immunisation campaigns in the US significantly polio cases. The epidemic was eliminated from the country in 1979.
As one of the last survivors to depend on an iron lung, Martha Lillard's life serves as a reminder of both the devastating impact of vaccine-preventable diseases and the extraordinary developments made in public health.
