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.

Nigeria is witnessing an outbreak of cholera, and to curb the spread of the disease, the police there have ordered sanitation measures in the northeastern state of Borno. According to the local media and authorities, about 39 people have died due to the waterborne disease. Local authorities have also reported at least 4,204 cases of infection.

According to the local health authorities, the outbreak is spreading in the Borno capital, Maiduguri, and the surrounding Jere district. The state police commissioner "has directed the full enforcement of the monthly environmental sanitation exercise." The statement added, "Residents are therefore urged to actively participate in the exercise by cleaning their homes, business premises, drainage channels, and surrounding environments."

He added, "To ensure compliance, police personnel and other relevant stakeholders will be deployed to strategic locations across the state during the sanitation period."

The nation is very cautious about the outbreak and has taken several steps to contain the disease as much as possible. The state government has set dedicated treatment centers for public convenience. Notably, cholera is spread by bacteria-tainted water and food, which can easily cause dehydration and diarrhoea.

The advent of modern sewerage systems has eradicated diseases throughout the modern world. Though war, conflict, and social unrest in nations like Nigeria and Sudan result in these unfortunate outbreaks, which take thousands of lives and affect many families.

As Ebola is spreading in African nations of the Democratic Republic of the Congo (DRC) and Uganda, another breakout of Cholera in Nigeria is showing the vulnerabilities of how rampant it is in Africa.

What Is Cholera?

According to the Centers for Disease Control and Prevention (CDC), it is caused by the bacterium Vibrio cholerae. This can be transmitted through drinking water or eating food that contains the bacteria. While most people who get cholera don't get sick, it can cause life-threatening diarrhea and vomiting.

CDC notes that each year, 1.3 to 4 million people around the world get cholera. Among them, 21,000 to 143,000 people die.

What Are The Common Symptoms?

The common symptoms include:

• watery diarrhea
• vomiting
• leg cramps
• losing body fluids
• dehydration and shock

Usually, people develop symptoms within 1 to 10 days of consuming the bacteria.

Who Is At More Risk?

People who live in areas with unsafe drinking water, poor sanitation, and inadequate hygiene are at the highest risk of getting cholera. The disease can spread quickly in areas where sewage and drinking water are not adequately treated. It can also live in brackish water, which is slightly salty, or in coastal water. Thus, eating raw shellfish can also cause cholera.

COVID-19, a name that can trigger a plethora of bad memories and constant fear, a time of solitude and captivity. Though now a breakthrough in medical science connected with coronavirus is giving hope to the possible prevention of Ebola. The universal vaccine was designed entirely by artificial intelligence (AI), and more importantly, it was successful.

It was the first time an AI-designed vaccine has completed a human clinical trial. The results of the trials were published in the Journal of Infection, and according to that report, phase one of the trial was observed by 39 healthy adult volunteers aged 18 to 50 and demonstrated a 100 pc safety profile.

The study stated that this vaccine was developed by the research team at the University of Cambridge and the company DIOSynVax, and they claimed that their vaccine has strong immune responses against various coronavirus strains.

And with this very crucial discovery in medical science, there is also a hope for designing a very effective vaccine for Ebola. Essentially, offering a proactive shield against a disease that continues to pose a significant global public health risk.

How Will This Breakthrough Contribute To The Development Of An Ebola Vaccine?

The vaccines that are traditional often tend to be reactive in nature, which means they can only work on a particular strain of a virus, and as a result, when the virus mutates and evolves, it becomes obsolete.

Artificial intelligence or machine learning can make a big difference in this aspect as it scans the genetic sequences of an entire family of viruses. The development of a universal COVID vaccine followed the same process. The AI pointed out the core features common to all of them, including strains that haven't even crossed over to humans yet, and after that, it has designed the new vaccine.

Though this very vaccine will not directly work on Ebola, the same process and technology can be used to create a similar vaccine in record time for Ebola as well. As the situation of the disease worsens by the day, it has crossed 500 cases.

As of Saturday, the Democratic Republic of the Congo (DRC) reported that its total number of Ebola cases had increased to 488 from 452 cases and caused 86 deaths. Its neighbor, Uganda, also has reported 19 cases.

This time, the Ebola outbreak has caused most harm to the Democratic Republic of the Congo (DRC), and during this mayhem, its neighboring nation, Uganda, which is also fighting to contain the disease as it is also seeing a surge in cases, has completely closed off its western border with DRC.

The World Health Organization (WHO) has declared the outbreak an international public health emergency, and the Centers for Disease Control and Prevention (CDC) warned that the Ebola outbreak of this time could swell to become the largest Ebola epidemic in history.

The situation regarding the outbreak of Ebola is nowhere near slowing down, and the World Health Organization (WHO) said that this outbreak of Ebola is far from under control. The outbreak of the disease in eastern Democratic Republic of the Congo (DRC) and neighboring Uganda has already reached the 500 mark.

On Saturday, the Democratic Republic of the Congo (DRC) reported that its total number of Ebola cases had increased to 488 from 452 cases and caused 86 deaths. Its neighbor, Uganda, also has reported 19 cases.

This time the Ebola outbreak has caused most harm to the Democratic Republic of the Congo (DRC) and during this mayhem its neighboring nation Uganda which is also fighting to contain the disease as it is also seeing surge in cases thus it has completely closed off its western border with DRC.

The worsening condition of the situation is clear, as the global health monitoring organization, the World Health Organization (WHO), has already declared the outbreak an international public health emergency.

And it's not only the case with WHO, another big name in public health, but the United States' Centers for Disease Control and Prevention (CDC) warned that the Ebola outbreak of this time could swell to become the largest Ebola epidemic to date, and is likely to rival the 2014-2016 epidemic in West Africa.

The patient number is still growing as the disease is spreading, and this spread is very hard to contain without an approved vaccine. Though work on the vaccine is in full swing, research on three different vaccines for the Bundibugyo strain of Ebola still needs time, even after being set to be fast-tracked for trials.

What Is Ebola?

Ebola is a severe and deadly disease caused by a virus mostly found in Africa. The spread of the disease happens through contact with infected body fluids.

Some symptoms can indicate a possible infection. This includes fever, headache, weakness, vomiting, diarrhea, muscle pain, sore throat, and unexplained bleeding. This eventually leads to severe complications like bleeding, organ failure, and death.

Ebola is a highly lethal viral hemorrhagic fever first identified in 1976. Over the past five decades, it has caused over 30 outbreaks, primarily in Central and West Africa. The virus takes its name from the Ebola River in the Democratic Republic of the Congo (DRC).

Three strains of the virus — Ebola virus, Sudan virus, and Bundibugyo virus — have caused the largest outbreaks in Africa. Among them, the Ebola virus is considered the deadliest, with fatality rates reaching up to 90% without treatment.

These viruses have repeatedly emerged from animal reservoirs and infected humans in African countries. In the Democratic Republic of the Congo alone, this marks the 17th Ebola outbreak and the third linked to the Bundibugyo strain.
