Pakistan continues to be dealing with a polio outbreak as four fresh cases have emerged, pushing the national tally to 37 this year, according to health officials on October 19, 2024. Health officials said that the regional reference laboratory for polio eradication at the National Institute of Health in Islamabad confirmed wild poliovirus type-1 (WPV1) in two children-one from each Balochistan and Khyber-Pakhtunkhwa.

In recent cases, a girl has been affected from Pishin, and two boys from Chaman and Noshki of Balochistan, and a girl from Lakki Marwat in KP. These are the first detections of the virus within Noshki and Lakki Marwat this year; isolated cases of poliovirus were previously reported within Chaman and Pishin. The province of Balochistan was the worst hit with 20 cases, Sindh had 10, Khyber Pakhtunkhwa had five, and Punjab and Islamabad had one case each.

A gigantic fight against polio has been on going in Pakistan- especially in Balochistan and southern KP-over the last two years. Immunisation campaigns have often been suspended or delayed because of local protests, insecurity, and community boycotts. Consequently, quite a number of children did not get the necessary vaccinations, making existing patches of vulnerability for the virus to flow within those pockets.

Noshki, located near Afghanistan's border, and Lakki Marwat have also recently reported some positive environmental samples that confirm the virus is present here, said a local reference laboratory official. Samples of latest cases are currently under genetic sequencing for checking spread of virus and origin.

As the threat of polio continues to grow, Pakistan has vowed to mount a nationwide campaign against it beginning from October 28. With the zeal to tackle the menace in the most effective manner, over 45 million children under the age of five will be vaccinated across the country.

Today, Afghanistan and Pakistan remain one of the few countries where polio has not yet been eradicated. The WHO said the virus remains a potential serious public health threat in areas with low vaccination coverage and weak surveillance.

India On Alert Against Polio

The country declared itself polio-free since 2014 and has kept the disease on bay almost a decade with very robust vaccination programs; however, two cases of vaccine-derived poliovirus cases reported in recent days from Meghalaya create some amount of doubts over a possible resurgence. Experts observe that in India, despite these detections taking place, strong coverage of vaccination at 90-95% and mandatory surveillance measures keep the risk of this widespread outbreak at bay.

The experts point out, however, that such stable situation in India requires continued surveillance. "Countries like Pakistan and parts of Africa remain at a high risk because vaccination rates in those areas are much lower," Dr. Siddharth, public health expert, said. Vaccination is an indispensable act in order to avoid the spread of this incapacitating disease that manifests most importantly as a nervous system affliction leading to the paralysis of a long period.

With concerted efforts from health authorities, there is hope someday that the scourge of polio will be completely eradicated from the face of the earth and future generations will never suffer from its effects.

The US Food and Drug Administration (FDA) has granted tentative approval to Dr. Reddy's Laboratories for the first generic version of lenacapavir, a long-acting injectable for HIV prevention. The development raises hopes of making HIV prevention more affordable in 120 low- and middle-income countries, including India.

The approval is considered “tentative”, the FDA’s standard designation for generics while the originator remains under patent.

The development comes just 16 months after Gilead Sciences received approval for its original product, marking one of the fastest timelines for a major HIV innovation.

Lenacapavir is the first twice-yearly injectable pre-exposure prophylaxis (PrEP) option for HIV prevention. Dr. Reddy's generic injection is expected to cost US$40 per person annually across the 120 eligible countries, with initial supplies expected by the end of 2026.

Calling it “a moment of immense pride”, Deepak Sapra, Chief Executive Officer, API and Services, at Dr. Reddy's, said the FDA approval validates the company's efforts to expand access to twice-yearly HIV prevention across low- and middle-income countries.

Dr Reddy's First Of 6 Generic Drugmakers To Get FDA Nod

In October 2024, Gilead Sciences signed voluntary licensing agreements with six generic manufacturers to produce and supply low-cost versions of lenacapavir in 120 low- and middle-income countries.

The six manufacturers are:

• Dr. Reddy's Laboratories (India)
• Emcure Pharmaceuticals (India)
• Hetero Labs (India)
• Eva Pharma (Egypt)
• Ferozsons Laboratories (Pakistan)
• Mylan (a subsidiary of Viatris)

Dr. Reddy's is the first among the six licensees to receive tentative US FDA approval. The other five companies are at various stages of product development, bioequivalence testing and regulatory filing.

What Will Cheaper Lenacapavir Mean For India?

At its August 11, 2026, meeting, the Indian drug regulator's Subject Expert Committee recommended waiving local Phase III clinical trials and bioequivalence studies for generic injectable lenacapavir applications submitted by Dr. Reddy's and Emcure Pharmaceuticals for PrEP.

The proposed price of approximately US$40 per person annually could make twice-yearly HIV prevention more accessible.

However, this is an indicative price for generic supplies, not a confirmed retail price in India. The eventual Indian price will depend on regulatory approval, manufacturing costs, supply capacity, competition and distribution.

What Does The Approval Mean For HIV Prevention?

Generic lenacapavir could offer people at risk of HIV an alternative to daily oral PrEP pills. Its twice-yearly dosing may help those who struggle with daily medication adherence or face stigma and barriers to healthcare access.

“For someone at risk of HIV, taking a pill every day to prevent a disease they do not have is a hard thing to ask. Two injections a year of a product that is almost 100% effective at preventing HIV changes that entirely.”

“Generic lenacapavir has the potential to transform HIV prevention, and this is a significant milestone, but an affordable drug alone is not enough,” said Professor Saiqa Mullick, Director of Implementation Science at Wits RHI, University of the Witwatersrand, which partnered with Dr. Reddy's.

Lenacapavir: How Does It Work?

Lenacapavir is a long-acting antiretroviral drug developed by Gilead. For HIV prevention, it is administered as two injections in the abdomen, providing protection for six months.

People must test negative for HIV before receiving it. The drug does not treat existing HIV infections or prevent other sexually transmitted infections.

Two major clinical trials demonstrated its high efficacy. In one study involving adolescent girls and young women in South Africa and Uganda, there were zero new HIV infections among participants who received lenacapavir. A second trial involving gay men and gender-diverse individuals also demonstrated high efficacy with twice-yearly injections.

Increasing consumption of caffeinated energy drinks and stimulant-containing supplements has been linked to a higher frequency of reported serious cardiovascular events, including cardiac arrest, heart attacks and abnormal heart rhythms, particularly among young adults, according to preliminary research.

The findings, based on an analysis of US Food and Drug Administration (FDA) safety reports, will be presented at the American Heart Association's (AHA) Scientific Sessions 2026, scheduled for November 6-9 in Chicago.

Researchers found that cardiac arrest was reported about 11 times more frequently in connection with caffeine- and

stimulant-containing products than products without these ingredients.

Energy Drinks And Heart Problems: What Did The Study Find?

Researchers analyzed 28,345 reports of possible adverse events submitted to an FDA safety database between 2017 and 2025. Of these, 854 involved energy drinks and supplements containing caffeine or other stimulants.

Key findings included:

• Cardiac arrest was reported about 11 times more frequently with caffeine- and stimulant-containing products.
• Heart attacks were 4.5 times more likely to appear in these reports.
• Ventricular arrhythmias and heart palpitations were reported about four times more frequently.
• Elevated heart rate was reported nearly three times more frequently.
• Chest pain was reported 2.71 times more frequently, while fainting was reported about twice as frequently.

About 45% of reports involving cardiovascular events and these products concerned adults aged 18 to 34. Similar patterns were observed among men and women.

Why Are Energy Drinks Raising Concerns?

Sales of caffeinated energy drinks have more than doubled over the past decade, reaching over $20 billion in 2024.

According to the AHA's 2026 scientific statement on caffeine and cardiovascular disease, consuming up to 400 mg of caffeine daily is generally safe for most adults.

However, some energy drinks contain up to three times more caffeine per fluid ounce than brewed coffee. Certain pre-workout supplements contain more than 12 times as much.

High caffeine intake has been associated with cardiovascular harm. Healthcare professionals have also reported cases of arrhythmias and sudden cardiac death following consumption of these products, including among young adults without known heart disease.

Why Are Young Adults Particularly Affected?

Researchers do not yet know why young adults account for such a large proportion of the cardiovascular event reports.

Possible explanations include frequent consumption, using these products before intense exercise, combining them with alcohol or other drugs, and undiagnosed heart conditions.

"These products are marketed as everyday pick-me-ups and sold next to soda and bottled water, so most people assume they carry no real risk," said study author Sai Samayamanthula, a fourth-year medical student at the University of Virginia School of Medicine.

He cautioned that regular consumers could quickly exceed recommended daily caffeine limits.

The researchers recommended better safety monitoring and urged healthcare professionals to ask younger patients experiencing palpitations, chest pain or fainting about their energy drink and stimulant supplement consumption.

The findings indicate an association, not proof that energy drinks cause cardiac arrest or other cardiovascular conditions.

Gregory M. Marcus, chair of the AHA's 2026 scientific statement on caffeine and cardiovascular disease, said the research raises concerns about products containing very high amounts of caffeine.

"Although there are biological reasons why that connection could be possible, the study does not prove that caffeine products cause these events, because other factors may have influenced the results," said Marcus, who was not involved in the study, and a professor of medicine at the University of California, San Francisco School of Medicine.

What Are The Study's Limitations?

The study relied on voluntary reports submitted to the FDA by consumers, healthcare professionals and manufacturers. Researchers could not determine how many people consumed these products without experiencing adverse events or how many cardiovascular events went unreported.

Billionaire investor Warren Buffett has reportedly said that he has not drunk plain water in 48 years, preferring his favourite soft drink instead.

Billionaire Bill Ackman recalled a dinner conversation with Buffett during an appearance on a recent podcast, where the legendary investor's drinking habits left him surprised, Business Insider reported.

During the dinner, Ackman offered Buffett a choice between still and sparkling water. However, the investor declined both. Curious about his preference, Ackman asked whether he drank water at all.

Buffett's reported response left him surprised.

"Bill, I haven't had water in 48 years," Buffett reportedly told Ackman.

Ackman, knowing about Buffett's fondness for Cherry Coke, had stocked up on the beverage ahead of the meeting.

Buffett's fondness for Coca-Cola is no secret and goes back decades. He has spoken about his preference for the beverage for years, and his association with the brand goes back to the 1980s. He also declared Cherry Coke the official beverage of Berkshire Hathaway's annual shareholder meeting.

What Happens If You Replace Plain Water With Coke?

Coca-Cola can contribute to your daily fluid intake, but that does not make it a healthy substitute for plain water. Regular Coke contains added sugar and calories, which can have consequences for health when consumed frequently.

According to the US Centers for Disease Control and Prevention (CDC), frequent consumption of sugar-sweetened beverages is associated with several health problems, including:

• Weight gain and obesity.
• Type 2 diabetes.
• Heart disease.
• Non-alcoholic fatty liver disease.
• Tooth decay and cavities.
• Gout, a type of arthritis.

Unlike plain water, which contains no calories, regular soft drinks add sugar and calories to the diet without providing comparable nutritional benefits.

Replacing water with sugary drinks regularly can therefore increase a person's overall sugar and calorie intake, potentially affecting metabolic and dental health over time.

Sugar-sweetened beverages include regular sodas, fruit drinks, sports drinks, energy drinks, sweetened water, and coffee and tea beverages with added sugars.

The CDC notes that replacing added sugars with low- or no-calorie sweeteners may reduce calorie intake in the short term and help with weight management. However, questions remain about their effectiveness as a long-term weight management strategy.

Why Is Drinking Enough Water Important?

According to the CDC, getting enough water every day is essential for health. Water helps prevent dehydration and allows the body to function normally.

Dehydration can cause unclear thinking, mood changes, overheating, constipation and kidney stones.

Water plays several important roles in the body. It helps:

• Maintain a normal body temperature.
• Lubricate and cushion joints.
• Protect the spinal cord and other sensitive tissues.
• Remove waste through urination, perspiration and bowel movements.

The body's water requirements may also increase in hot climates, during physical activity, or when a person has a fever, diarrhoea or vomiting.

Water contains no calories. Replacing sugary drinks with plain water can therefore help reduce overall calorie intake.
