Polio Outbreak in Pakistan

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.

WHO's New Dementia Guidelines Prioritize Healthy Habits, Warn Against Supplements

Updated Jul 15, 2026 | 08:00 PM IST

SummaryWhile there is currently no cure, the WHO says up to 45 per cent of dementia risk can be prevented or delayed by addressing modifiable risk factors such as tobacco and alcohol use, physical inactivity, social isolation, air pollution, and high blood pressure and diabetes.

The World Health Organization (WHO) today released updated guidelines aimed at reducing the risk of cognitive decline and dementia, a condition that affects more than 57 million people worldwide.

Nearly 10 million people are diagnosed with dementia every year. While there is currently no cure, the WHO says up to 45 per cent of dementia risk can be prevented or delayed by addressing modifiable risk factors such as tobacco and alcohol use, physical inactivity, social isolation, air pollution, and noncommunicable diseases (NCDs), including high blood pressure and diabetes.

Beyond its impact on memory, thinking and daily functioning, dementia also affects a person's independence, dignity and safety.

"We know more today than ever before about what drives dementia risk, and these guidelines translate that knowledge into action," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General.

"Countries now have clear, evidence-based recommendations they can put into practice immediately to protect people's cognitive health," he added.

What Do the Updated WHO Guidelines Say?

The WHO last issued recommendations on dementia risk reduction in 2019. The global healthy body said that the updated guidelines incorporate the latest scientific evidence and innovations in dementia prevention. The revised recommendations also provide proven interventions that can lower dementia risk through early awareness and timely action.

Further, they present an opportunity to reduce the global burden of dementia by strengthening the integration of brain health with noncommunicable disease and mental health services.

Importantly, the updated guidelines recommend several healthy behaviors and lifestyle interventions to reduce the risk of cognitive decline and dementia, including:

  • Cognitive training and cognitive stimulation
  • Participation in social activities for adults with normal cognition or mild cognitive impairment
  • Regular physical activity
  • Quitting tobacco
  • Reducing alcohol consumption
  • Following a healthy diet
  • Reducing exposure to air pollution

The WHO also recommends effective management of cardiometabolic conditions such as hypertension, diabetes and high cholesterol as part of dementia risk-reduction strategies. Hearing aids may also be offered where appropriate, it said.

WHO Warns Against Routine Supplements

The WHO does not recommend the routine use of vitamin B and E supplements, omega-3 polyunsaturated fatty acids (PUFA), or multivitamins and minerals to prevent cognitive decline or dementia in people without a diagnosed deficiency.

According to the organization, current evidence does not demonstrate sufficient benefit to outweigh potential harmful effects.

What Is Dementia?

Dementia is an umbrella term describing a significant decline in mental function that interferes with everyday life. It commonly affects memory, thinking and reasoning abilities and is caused by underlying conditions such as Alzheimer's disease or vascular dementia.

Common Signs of Dementia

  • Memory problems
  • Confusion
  • Difficulty finding words
  • Changes in mood or behavior
  • Trouble completing familiar tasks

The Growing Global Burden

Dementia significantly affects an individual's ability to live independently, work and perform daily activities while placing a substantial burden on families and caregivers.

According to the WHO, dementia costs the global economy an estimated US$1.3 trillion every year, with about half of that amount attributed to unpaid care provided by family members and friends.

The WHO said understanding dementia risk factors and taking preventive action can improve health and quality of life, helping people live longer, healthier and more independent lives.

Simple Androgen Blood Test Could Identify Endometriosis With 95% Accuracy

Updated Jul 15, 2026 | 06:00 PM IST

SummaryThe researchers discovered that women with endometriosis consistently had higher levels of 11-ketotestosterone, one of the 11-oxygenated androgens, which enabled them to differentiate women with and without endometriosis.

A simple blood test that measures androgen hormone levels could help diagnose endometriosis with more than 95 per cent accuracy, according to new research.

The University of Edinburgh-led findings offer hope for a faster, less invasive way to detect the condition, which affects an estimated 10 per cent of women of reproductive age worldwide—around 190 million people—and often takes years to diagnose.

The researchers found that women with endometriosis have a distinct androgen hormone profile in their blood, suggesting the condition could one day be identified through a simple blood test rather than invasive procedures.

Study Identifies a Unique Hormone Signature

The research team analyzed blood samples from 159 women with confirmed endometriosis and 57 women without the condition. Their investigation focused on androgen hormones, including a lesser-studied group known as 11-oxygenated androgens, which are produced by the adrenal glands.

The researchers discovered that women with endometriosis consistently had higher levels of 11-ketotestosterone, one of the 11-oxygenated androgens.

Using this distinct hormone profile, the team was able to differentiate women with and without endometriosis, correctly identifying more than 95 per cent of those with the condition.

If validated in larger clinical studies, the test could reduce reliance on invasive diagnostic procedures such as laparoscopy and help women receive treatment much earlier.

The findings also provide new insights into the role of androgens in the development of endometriosis and may help guide future treatment strategies.

Why Androgens Matter

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the womb. These cells respond to hormones, leading to inflammation, chronic pelvic pain and the formation of scar tissue.

While the disease is known to be influenced by the female hormones estrogen and progesterone, the role of androgens—often referred to as male hormones, though they are naturally present in women as well—has received comparatively little attention.

The researchers believe the newly identified androgen signature could improve understanding of how the disease develops and progresses.

Why Earlier Diagnosis Is Important

Diagnosing endometriosis remains a major challenge. Current methods include ultrasound, MRI scans and laparoscopy—a surgical procedure in which a camera is inserted through a small incision in the abdomen to confirm the presence of endometrial-like tissue.

Because symptoms often overlap with those of other conditions, many women wait years before receiving a diagnosis. Earlier diagnosis could help reduce prolonged pain, limit disease progression and allow patients to begin treatment sooner, said the researchers, while stressing the need for larger studies.

What Is Endometriosis?

According to the World Health Organization (WHO), endometriosis is a chronic condition in which tissue similar to the lining of the uterus grows outside the uterus. It most commonly affects the ovaries, fallopian tubes and the tissue lining the pelvis.

The condition can begin with a person's first menstrual period and continue until menopause. Common symptoms include severe pelvic pain, painful periods, pain during intercourse, bowel or urinary symptoms during menstruation, and difficulty conceiving.

COVID Spikes In India: Experts Allay Fears, Stress Vaccination And Masks

Updated Jul 15, 2026 | 05:00 PM IST

SummaryThe experts said that the current wave is being driven by Omicron subvariants — the JN.1 variant and the BA.3.2 variant — that remain highly transmissible but are not causing severe illness in most people.

The recent rise in COVID-19 cases and deaths in Andhra Pradesh has renewed concerns over the virus, prompting neighbouring states such as Tamil Nadu and Odisha to step up surveillance. Andhra Pradesh has reported three COVID-related deaths along with several active cases.

However, health experts say the current situation does not indicate a major public health threat and have urged people to focus on prevention rather than panic.

Tamil Nadu's Health Department has also clarified that there is no evidence of a highly virulent COVID-19 variant circulating in the state. Officials noted that current COVID-19 infections remain lower than in previous years.

Virus Continues To Evolve

"The SARS-CoV-2 virus never truly disappears; it continues to resurface through new mutations. Viral strains naturally mutate as part of their evolution, making viral illnesses highly dynamic," Dr Abha Mashur, Pulmonologist at Lilavati Hospital and Research Centre, Mumbai, told HealthandMe.

She said the key concern is not the emergence of new variants, but the severity of disease they cause.

"At present, we are predominantly seeing upper respiratory involvement and milder cases of viral illness," said Dr Mashur, adding that Lilavati Hospital has admitted only one or two COVID-19 patients recently, all of whom required monitoring but experienced only mild illness.

Who Is At Higher Risk?

While most infections are mild, experts caution that certain groups remain vulnerable to severe disease. These include:

  • Elderly individuals
  • Pregnant women
  • People with chronic heart disease
  • Patients with COPD or interstitial lung disease (ILD)
  • Those with chronic kidney or liver disease
  • Immunocompromised individuals.

Omicron Subvariants Circulating In India

According to Dr Mashur, the current wave is being driven by Omicron subvariants — the JN.1 variant and the BA.3.2 variant — that remain highly transmissible but are not causing severe illness in most people.

JN.1: The expert explained that the JN.1 variant is highly transmissible and possesses enhanced immune-evasion capabilities, allowing it to partially bypass immunity from previous infection or vaccination. However, she said it continues to cause predominantly mild illness compared to earlier variants.

BA.3.2: The BA.3.2 variant has accumulated a large number of mutations, raising concerns about immune escape. Despite this, available evidence suggests it has not led to more severe disease and is not currently considered a cause for alarm.

No Need for Panic

The experts stressed that the current rise in cases should encourage vigilance rather than fear. Vaccination, masking in high-risk settings, and early medical consultation remain the most effective tools to reduce transmission and protect vulnerable populations.

"The current situation should not create panic, but should prompt people to seek medical attention early. Those who develop symptoms of a viral infection should avoid public spaces and consult a doctor promptly so that transmission can be curtailed at the earliest," Dr Mashur said.

Dr Neha Rastogi, Senior Consultant, Infectious Diseases, Fortis Memorial Research Institute, Gurugram, urged people to continue following basic preventive measures.

"To reduce the risk of infection, people should stay up to date with COVID-19 vaccinations, wear masks in crowded indoor settings, maintain hand hygiene, ensure good ventilation, and avoid close contact when unwell. Anyone experiencing symptoms such as fever, cough, or breathlessness should get tested and seek timely medical advice."
