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.

What Is The Role Of Preventative HIV Medicines?

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.

HIV In Japan

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.

What Are The Challenges In Implementation?

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.

Better Healthcare Support

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.

What Is The Way Ahead?

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.

Crusted Scabies Outbreak: UK Reports Rare Highly Contagious Skin Disease

Updated Jul 10, 2026 | 03:22 PM IST

SummaryUnlike classic scabies, patients with crusted scabies may not experience severe itching or develop the typical rash, making the condition more difficult to recognize. However, they can carry up to two million mites and eggs, making them extremely contagious

The UK has reported an outbreak of crusted scabies, a rare and highly contagious form of scabies, prompting the temporary closure of a hospital ward in Wales.

According to the Hywel Dda University Health Board, Steffan Ward at Glangwili Hospital in Carmarthen has been temporarily closed while the outbreak is managed under established infection prevention and control measures, according to the BBC.

Health officials said all patients and staff identified as close contacts have been informed and offered treatment, even if they are not showing symptoms. Enhanced infection control measures, including monitoring, treatment of identified contacts, and specialist support, have also been put in place.

Officials added that a recent rise in scabies cases across Carmarthenshire, Pembrokeshire, and Ceredigion has contributed to outbreaks in healthcare settings. The ward will reopen once it is deemed safe under infection control guidance.

What Is Crusted Scabies?

Scabies is a highly contagious skin infestation caused by the microscopic mite Sarcoptes scabiei. The mites burrow into the upper layer of the skin, where they lay eggs, triggering an allergic reaction that causes intense itching and a rash.

However, the crusted scabies—previously known as Norwegian scabies—is a severe form of the infestation in which the skin develops thick, crusted plaques that may crack and become inflamed, according to the US Centers for Disease Control and Prevention (CDC.

Unlike classic scabies, patients with crusted scabies may not experience severe itching or develop the typical rash, making the condition more difficult to recognize. However, they can carry up to two million mites and eggs, making them extremely contagious.

Because of the heavy mite burden, crusted scabies can rapidly spread in healthcare facilities and long-term care homes if not identified and treated promptly. It may also lead to serious complications, including secondary bacterial infections and sepsis.

Who Is Most at Risk?

People at increased risk of developing crusted scabies include:

  • Older adults
  • People with weakened immune systems, including those living with HIV/AIDS
  • Individuals with conditions that reduce the ability to itch or scratch, such as spinal cord injuries, paralysis, loss of sensation, or severe neurological or behavioural disorders

How Can Crusted Scabies Be Prevented?

Preventing outbreaks requires rapid diagnosis, prompt treatment, and strict infection control measures.

Health authorities recommend:

  • Identifying and treating all close contacts, including household members, caregivers, and sexual partners
  • Isolating affected individuals when necessary
  • Washing or decontaminating bedding, clothing, and towels used by infected patients
  • Maintaining strict hygiene and environmental cleaning in healthcare settings

Why Early Diagnosis Matters

Early diagnosis is critical to preventing further transmission. Since crusted scabies may not present with the classic symptoms of itching and rash, healthcare professionals play an important role in recognising the condition.

Only a qualified healthcare provider can confirm the diagnosis and prescribe appropriate treatment. Prompt medical care helps reduce the risk of complications and prevents outbreaks in hospitals, nursing homes, and other communal settings.

Chandipura Virus Claims 3 Children In Gujarat, Rajasthan: Why Kids Are At Risk Of This Rare Brain Infection

Updated Jul 10, 2026 | 02:37 PM IST

SummaryThe Chandipura virus can rapidly invade the brain, causing acute encephalitis (brain inflammation), seizures, coma and even death, especially in children. There is currently no specific antiviral treatment or vaccine for Chandipura virus. Prevention focuses on avoiding insect bites and reducing exposure to sandflies.

The Chandipura virus (CHPV), a rare but potentially fatal brain infection, has claimed the lives of three young children in Gujarat and Rajasthan, raising concerns during the ongoing monsoon season when insect-borne diseases become more common.

A six-year-old boy from Rajasthan with a confirmed Chandipura virus infection died at the Civil Hospital in Himmatnagar, Gujarat's Sabarkantha district, officials said on July 9.

According to Resident Medical Officer Dr. Vipul Jani, seven children aged between 2 and 11 years with suspected CHPV infection were admitted to the hospital between June 26 and July 9.

The child with confirmed infection was identified as Rajkumar Damor (6), a resident of Udaipur, Rajasthan.

Two girls—a two-year-old from Rajasthan and a three-year-old from Sabarkantha, Gujarat—are currently undergoing treatment, while laboratory reports are awaited. Another three-year-old boy tested negative and has been discharged.

What Is Chandipura Virus?

Chandipura virus (CHPV) is an insect-borne virus belonging to the Rhabdoviridae family and the Vesiculovirus genus. It was first identified in 1965 in Chandipura village in Maharashtra.

The virus is transmitted primarily through phlebotomine sandflies, although mosquitoes and ticks may also play a role in transmission.

Most cases have been reported from central and western India, particularly during the monsoon and post-monsoon months when sandfly populations increase.

While some infections remain mild, the virus can rapidly invade the brain, causing acute encephalitis (brain inflammation), seizures, coma and even death, especially in children.

"In some children, Chandipura virus can cause severe brain inflammation and become life-threatening within a short period," said Dr. Kanchankumar Bhagyawant, Consultant Paediatrician and Neonatologist at Ruby Hall Clinic, Pune.

Symptoms Of Chandipura Virus Infection

Symptoms usually begin suddenly and may initially resemble other viral illnesses. The expert urged to watch out for:

  • Sudden high fever
  • Severe headache
  • Vomiting
  • Excessive sleepiness or reduced activity
  • Irritability or behavioural changes
  • Convulsions or seizures
  • Loss of consciousness in severe cases

"Parents should never ignore a fever lasting more than three days if it is accompanied by repeated vomiting, seizures, confusion or excessive sleepiness. Seeking immediate medical care can be lifesaving," Dr. Bhagyawant said.

Why Are Children More At Risk?

According to Dr. Bhagyawant, children below 15 years, especially those living in rural and semi-rural areas, are the most vulnerable to Chandipura virus infection. Although adults can be infected, severe disease is far less common.

"The Chandipura virus infects young children, leading to inflammation of the brain called encephalitis," Dr. Rajeev Jayadevan, former President of the Indian Medical Association (IMA) Cochin and Convener of the Research Cell, Kerala told HealthandMe.

Children are at greater risk because of several factors:

  • Immature immune system: Young children have fewer antibodies and are less able to fight new viral infections.
  • Higher exposure: Outdoor play increases contact with sandflies, particularly during the monsoon.
  • Limited prior immunity: Most children have not been previously exposed to the virus.
  • Rapid disease progression: The virus can multiply quickly, overwhelming a child's immune system.
  • Developing brain: Children's brains are more vulnerable to encephalitis and neurological damage.
  • Delayed diagnosis: Early symptoms resemble common viral infections, delaying treatment.
  • Limited healthcare access: Rural areas may have fewer diagnostic and treatment facilities.
  • Poor vector control: Inadequate measures to control sandflies increase the risk of transmission.

How Can Chandipura Virus Infection Be Prevented?

"There are no known anti-virals or vaccines, which means that our treatment is dependent on the patient receiving early medical attention and supportive care. Children are the victims. Vector control, avoiding bites, especially in monsoon seasons is important," Jayadevan said.

Dr. Bhagyawant recommended:

  • Use mosquito or sandfly nets, especially for children at night.
  • Apply age-appropriate insect repellents.
  • Dress children in full-sleeved clothing and long pants.
  • Keep homes and surroundings clean.
  • Eliminate stagnant water and improve sanitation around homes and animal shelters.
  • Install window screens where possible.
  • Seek immediate medical attention if a child develops a high fever along with vomiting, seizures or altered consciousness.

Veteran radio and television broadcaster Paul Gambaccini has revealed that he has been diagnosed with Alzheimer's disease.

The 77-year-old presenter, who has been a regular on the BBC since the 1970s, shared a statement revealing that he received the diagnosis in 2025.

"As Freddie Mercury once sang, you can't turn back the clock, you can't turn back the tide. Ain't that a shame. There's no denying it's a serious condition with an uncertain future, but for now life goes on as normal,” he said.

Gambaccini added that he would "be as open as I can as things progress", and that he was grateful for the kindness and support he had already received.

"For now, I wish to be given the space to keep on broadcasting the music I love to the listeners I love even more. These are the days of our lives," he said.

The broadcaster said he would continue presenting The Paul Gambaccini Collection on BBC Radio 2 every Sunday, as well as his shows on Greatest Hits Radio.

The Alzheimer's Society said Gambaccini's experience "shows that there can be life after a dementia diagnosis", the BBC reported.

What Is Alzheimer's Disease?

Alzheimer's disease is the most common form of dementia and primarily affects adults aged 65 years and older. Around 1 million people are living with dementia in the UK.

Alzheimer's disease is characterized by the buildup of abnormal proteins in the brain—amyloid plaques and tau tangles—which damage nerve cells responsible for memory and thinking.

Amyloid proteins accumulate into sticky plaques between brain cells, while tau proteins twist into thread-like tangles inside neurons. Together, these changes disrupt communication between brain cells and eventually lead to their death.

Over time, this progressive damage affects memory, thinking, behavior, and the ability to carry out everyday activities. In advanced stages, people may lose the ability to communicate, care for themselves or respond to their surroundings.

Although the exact cause of Alzheimer's disease remains unclear, experts believe it results from a combination of genetic, biological and lifestyle factors. Physical inactivity, an unhealthy diet and social isolation may increase the risk of developing the condition.

Early symptoms often include forgetting recent conversations or events. As the disease progresses, memory loss becomes more severe and daily functioning becomes increasingly impaired.

There is currently no cure for Alzheimer's disease. In its advanced stages, complications such as dehydration, poor nutrition and infections can become life-threatening.

Common Symptoms Of Alzheimer's Disease

People with Alzheimer's disease may experience one or more of the following:

  • Memory loss that disrupts daily life, such as getting lost in familiar places or repeatedly asking the same questions.
  • Difficulty managing finances or paying bills.
  • Trouble completing familiar tasks at home, at work or during leisure activities.
  • Poor or declining judgment.
  • Frequently misplacing items and being unable to retrace steps to find them.
  • Changes in mood, personality or behavior.
