Heart attacks and strokes are among the leading causes of death globally, with millions suffering from cardiovascular diseases (CVD) every year. There are more than seven million people in the UK alone, with about 100,000 patients experiencing heart attacks annually. However, a group of researchers at University College London (UCL) estimate that one 'polypill' taken daily day could eliminate a majority of these cases dramatically lowering death tolls.

The proposed polypill, a combination of a statin and three blood pressure-lowering drugs, has been under study for over two decades. Experts argue that introducing this pill universally for individuals aged 50 and above could be more effective than the current NHS Health Check, which assesses risk factors every five years for those aged between 40 and 74.

Studies have repeatedly proven the effectiveness of the polypill in preventing CVD. A groundbreaking 2019 study in The Lancet found that five years' use of the polypill cut the risk of heart attack and stroke by a third. In addition, previous modelling analyses have estimated that if given universally to people over 55, the polypill might be able to prevent 80% of heart attacks and strokes.

Today, the NHS Health Check follows a risk-based model in which patients are tested for CVD risk factors and treated with drugs accordingly. Yet, as per UCL's study, this system has serious flaws:

Low Uptake: Just 40% of those eligible for the NHS Health Check choose to have it, leaving a considerable number of at-risk patients undiagnosed and untreated.

Ineffective Prediction of Risk: The majority of heart attacks and strokes happen to people at average risk levels, thus making it challenging to identify the need for intervention effectively.

Limited Effectiveness: Even at maximum take-up, the NHS Health Check programme is predicted to have fewer health impacts compared to a polypill initiative applied to the whole population.

Simplicity and Affordability of the Polypill Strategy

One of the big benefits of the polypill is that it is so easy. In contrast to the existing screening-based model, the polypill scheme would not involve complicated medical tests or lengthy risk assessments. Instead, people reaching 50 would just have to fill out a few questions to determine possible side effects before they were prescribed.

Professor Aroon Hingorani of the UCL Institute of Cardiovascular Science, one of the strongest proponents of this scheme, says:

"Finally, the time is now to do much better on prevention. A population approach would prevent a lot more heart attacks and strokes than is done today with a strategy of trying to target a smaller group only."

Aside from the possible health implications, the polypill is also an economic solution. The drugs used are off-patent, thus cheap to produce and distribute. With the vast economic cost of managing CVD-related illnesses, a preventive model could result in substantial cost-saving for the NHS in the future.

The polypill has been proven to be effective by numerous international trials. In 2019, a randomised trial in rural Iran discovered that participants who took the polypill for five years had a 34% reduced risk of having a heart attack or stroke compared to non-participants.

Likewise, modelling research has indicated that even if only 8% of people aged over 50 took up the polypill regimen, it would still be more beneficial to their health than the NHS Health Check programme.

Is This a Case of Over-Medicalisation?

One of the main objections to the polypill strategy is the suggestion that it might result in the unnecessary medicalisation of a significant proportion of the population. But, it is argued, it should be considered as a preventative measure, not as mass medication.

Professor Sir Nicholas Wald of UCL's Institute of Health Informatics explains:

"Instead of being a 'medicalisation' of a significant proportion of the population, a polypill programme is a prevention measure to prevent an individual from becoming a patient."

He compares it with public health measures like water fluoridation or compulsory seatbelts—interventions that have been shown to have a significant impact in reducing public health danger at low individual cost.

With the evidence in favour of the polypill's effectiveness and viability overwhelming, experts are calling on the NHS to act now. It is their belief that substituting the NHS Health Check with a polypill-based prevention program could be the UK government's flagship policy under its pledge to put disease prevention ahead of cure.

As Professor Hingorani points out, "The status quo is not a justifiable option." With CVD still a major cause of death globally, taking a population-wide polypill approach could be a turning point for preventative medicine, potentially saving thousands of lives annually. The question now is whether the NHS will take up this call and establish a policy with the potential to transform the prevention of cardiovascular disease on a national level.

The hantavirus outbreak, which began late in April aboard the MV Hondius cruise ship, is now stable, according to the World Health Organization (WHO).

Sharing opening remarks at the 159th session of the Executive Board today, WHO Director-General Tedros Adhanom Ghebreyesus said that no new cases and deaths of the rat-borne virus have been reported.

“The hantavirus outbreak is now stable, with one new case in the past two weeks, and no new deaths since May 2,” he said.

The outbreak resulted in 12 total cases (10 confirmed, 2 probable) and 3 deaths.

“All passengers and crew remain in quarantine and under close monitoring to ensure they receive care if needed,” the WHO Chief added.

All the passengers have been repatriated and will be monitored until the quarantine period ends on June 21. The crew will also be quarantined until June 29.

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

“There is no sign that we are seeing the start of a larger outbreak. But of course, that could change, and we urge all affected countries to continue monitoring the passengers and crew carefully. I thank the many countries involved in the response,” Tedros said.

The current outbreaks of Ebola and hantavirus remind us that the next pandemic will not wait for us, he noted, urging countries to work on making the Pandemic Agreement operational.

The WHO has confirmed that the Andes strain of hantavirus — the only strain known to spread from person to person — is behind the outbreak. The strain has no vaccine.

Meanwhile, the Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. said he signed a targeted Public Readiness and Emergency Preparedness Act declaration “to support the development and deployment of medical countermeasures related to the Andes virus” strain of hantavirus.

“This action helps remove barriers to research and response efforts while we continue monitoring the recent outbreak linked to the South Atlantic cruise ship,” Kennedy said in a statement posted to social media. “HHS is taking this situation seriously and will continue working to protect public health and support the safe development of potential treatments and countermeasures.”

What Is Hantavirus?

As per the WHO, hantaviruses are zoonotic viruses that naturally infect rodents and are occasionally transmitted to humans.

Globally, an estimated 100,000 to 200,000 hantavirus infections occur each year. The majority of these cases are in Asia, particularly China. Most are sporadic or occur in small clusters, linked to contact with infected rodents.

Infection in people can result in severe illness and often death, although the diseases vary by type of virus and geographical location.

Notably, the WHO has not specified the type of hantavirus or syndrome in the cruise incident, but did mention respiratory risks.

The hantavirus is primarily spread by rodents through

• exposure to their urine,
• droppings,
• saliva,
• less commonly through a scratch or bite.

The ongoing Ebola outbreak "is spreading rapidly" and "outpacing us", said Tedros Adhanom Ghebreyesus, Director General of the World Health Organization, today.

At the Virtual Ministerial Briefing on the Bundibugyo Ebola Outbreak today, he stated that "more than 900 suspected cases have been identified so far, including 101 confirmed cases".

Echoing concern, he noted that the epidemic is outpacing us.

"We are urgently scaling up operations, but at the moment the epidemic is outpacing us," Tedros said, adding that countries bordering the Democratic Republic of Congo, the epicenter of the outbreak, should take immediate action.

Officials informed that Uganda reported two more Ebola cases, taking its total number of confirmed cases to seven. The deadly virus has reportedly killed at least 220 people so far.

Tedros added that the "delay in detecting the outbreak means that we are now playing catch-up with a very fast-moving epidemic".

Ebola disease is a severe viral hemorrhagic fever with a high mortality rate.

The mounting cases of Ebola virus in the Democratic Republic of Congo and Uganda has kept India on alert mode.

The Union Minister of Health and Family Welfare, Jagat Prakash Nadda, today held another review meeting to check the country's preparedness and surveillance measures for Ebola disease.

“India has not reported any case of Bundibugyo Ebola disease to date," the Union Health Minister said.

The country has also issued a travel advisory for citizens to avoid non-essential travel to the Democratic Republic of the Congo, Uganda, and South Sudan.

The Union Health Ministry earlier issued Standard Operating Procedures (SOPs) on public health preparedness and response to Ebola disease, encompassing protocols for screening, quarantine, clinical management, laboratory testing, and infection prevention practices.

In addition, guidelines have been issued for hospital infection control, isolation facility preparedness, and for safe and dignified handling of human remains of Ebola patients.

Integrated Disease Surveillance Program (IDSP) units and Airport Health Organizations have been instructed to maintain heightened vigilance for unexplained febrile illness among international travelers and ensure prompt reporting and management of any suspected case.

Screening Intensified At Airports in India

Meanwhile, states like Maharashtra, Kerala, Andhra Pradesh, and Gujarat have intensified screening of passengers arriving from Ebola-affected countries like Uganda, Congo, and South Sudan.

The Union government has asked states to identify designated isolation facilities, arrange dedicated ambulances, and ensure availability of trained healthcare personnel, personal protective equipment (PPE), laboratory support, and critical care capacity.

An advisory is displayed at the Delhi airport by the Airport Health Organization (APHO) , advising passengers to watch out for symptoms such as:

• fever,
• weakness,
• headache,
• muscle pain,
• vomiting,
• diarrhea,
• sore throat,
• unexplained bleeding.

According to the APHO, any traveler developing symptoms within 21 days of arrival should seek immediate medical care and inform authorities about their travel history.

Ebola: An Antiviral On The Anvil

Even though the new Bundibugyo strain has no vaccine or antiviral, the WHO has recommended prioritizing two monoclonal antibodies for clinical trials.

"We are also recommending the evaluation of the antiviral obeldesivir in a clinical trial as post-exposure prophylaxis for people who are high-risk contacts," the WHO chief said.

This clinical trial is now being developed jointly with Africa CDC and the Collaborative Open Research Consortium on filoviruses, he noted.

As Delhi and most of North India continue to face rising temperatures, doctors have raised concerns over worsening air pollution, warning that the combination is placing severe stress on the human body, even among otherwise healthy individuals.

HealthandMe spoke to experts to understand how the overlap of heatwaves and polluted air can affect health.

According to experts, extreme heat and pollution together are no longer just an environmental issue, but are emerging as a serious urban health emergency.

Dr. Amit Kumar Mandal, Senior Director - Pulmonology at Paras Health, explained that extreme heat combined with pollution forces multiple organs to work harder simultaneously.

“People often think heatwaves only affect the skin or cause dehydration, but when extreme heat combines with high pollution levels, the body starts functioning as if it is constantly under attack,” he said.

The expert explained that "the lungs are forced to work harder to filter hot, polluted air, while the heart simultaneously struggles to regulate body temperature. This invisible overload can quietly trigger inflammation, breathing distress, sudden BP fluctuations, and cardiac strain, even in people who otherwise consider themselves healthy".

Symptoms Often Missed

Dr. Amit further noted that the subtle symptoms in the beginning often go unnoticed, making the combination even more dangerous.

The symptoms increasingly being seen during such weather conditions include

• persistent tiredness,
• irritability,
• disturbed sleep,
• headaches,
• chest heaviness,
• unusual breathlessness.

“Heat and pollution together are no longer just an environmental issue; they are emerging as a serious urban health emergency. Preventive care during summers now has to go beyond avoiding the sun; people need to actively protect their respiratory and cardiovascular health as well,” Dr. Amit told HealthandMe .

How Prolonged Exposure Can Affect Health

Dr. Rahul Punj, Senior Consultant - Internal Medicine at Yatharth Super Speciality Hospital, told HealthandMe that prolonged exposure to high temperatures and poor air quality can affect multiple systems in the body.

“Rising heat and increasing pollution levels are becoming major health concerns, especially in urban areas. Prolonged exposure to extreme temperatures and poor air quality can lead to dehydration, heat exhaustion, breathing difficulties, allergies, skin issues, and can even worsen heart and lung diseases. Children, elderly people, pregnant women, outdoor workers, and patients with asthma, COPD, or other chronic illnesses need to be extra cautious during this period,” he said.

Dr. Rahul advised people to take preventive measures seriously during heatwave conditions. Preventive measures that can help reduce health risks include:

• staying hydrated,
• avoiding direct sunlight during peak afternoon hours,
• wearing light cotton clothes,
• using masks in polluted areas,
• maintaining proper indoor ventilation.

Weather Today

Residents in Delhi continue to struggle against soaring temperatures and blazing sunshine. The India Meteorological Department (IMD) has issued a yellow alert for the next three days, warning of continued heatwave conditions along with strong surface winds during the afternoons and evenings.

The maximum temperatures are expected to increase by a further 1°C-2°C within the next 24 hours and are forecast to stay high until May 27.

The national capital recorded a maximum temperature of 43.6 degrees Celsius on Sunday, around 3.4 degrees above the seasonal average. The minimum temperature settled at 28.4 degrees Celsius in the morning, nearly two degrees above normal.

Last week, the Commission for Air Quality Management (CAQM) invoked Stage 1 of the Graded Response Action Plan (GRAP) across Delhi-NCR after the city’s air quality slipped into the ‘poor’ category.
