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.

New York City just rolled out new measures in a response to prevent Legionnaires’ disease after a major outbreak on the Upper East Side left 11 people dead and 94 infected.

The new measures, announced by Mayor Zohran Mamdani and the NYC Health Department on September 1, aim to improve monitoring of cooling towers, speed up testing and enforcement, and make information about possible risky systems easier for the public to access.

The Upper East Side cluster, which affected the Carnegie Hill and Yorkville neighborhoods, has now ended in terms of exposure.

However, investigation is still in progress to find out exactly how the outbreak began. Whole-genome sequencing results expected this fall could help determine whether the Legionella strain found in patients matches bacteria detected in nearby cooling towers.

One major change will connect the Health Department's cooling tower registration system with the Department of Buildings' construction permitting system.

The goal is to identify unregistered cooling towers before they begin operating, after the city found unregistered systems during both the Upper East Side investigation and a previous outbreak in Central Harlem.

New York will also create a citywide map of registered cooling towers, allowing residents to see their locations and review inspection histories, including whether buildings have complied with Legionella sampling requirements. The map and an annual public education campaign are expected by spring 2027.

Cooling tower owners cited for violations will receive the earliest hearing date permitted, which is 15 days after a summons is served.

Since May 8, the Health Department has conducted 800 field inspections, with more than 460 resulting in at least one violation. The city says $80,500 in fines have been paid.

Legionella bacteria can grow in warm water systems and become a health risk when contaminated water produces tiny droplets or mist that people breathe in.

Cooling towers are among the systems that can allow the bacteria to spread through the air. Most people exposed to Legionella do not become ill, but the risk is higher among older adults, smokers and people with chronic diseases or weaken immunities.

Speedy Testing And New Cooling Technology

As of August 31, 94 people had been diagnosed and 11 had died in the Upper East Side cluster. No patients remained hospitalized.

The Health Department plans to explore and implement faster culture-testing methods and other approaches that could reduce the time needed to confirm whether Legionella is present. This could be key in preventing future outbreaks.

The Upper East Side had nearly four times as many cooling towers in the affected area as were identified during the 2025 Central Harlem cluster, making rapid testing considerably more challenging.

The city will also establish a scientific team to examine new cooling tower technologies and alternative cooling systems.

NYC Health Commissioner Dr Alister F. Martin added, "Rigorous standards only matter if we are constantly working to make them stronger."

Parkinson’s disease has becoming increasingly common in the US, but new data show that the burden is heavier in some states than others.

An analysis of 2025 medical records of 46 million adults across 49 states found an evident geographic divide.

After adjusting for factors like age, sex, race, ethnicity and other health conditions, Nebraska recorded the highest rate at 561 Parkinson’s diagnoses per 100,000 people, followed by Kansas at 517 and Utah at 493. On the other hand, Montana recorded 308 diagnoses per 100,000.

Even though the findings do not prove that living in a particular state causes Parkinson’s, researchers say the pattern raises important questions about environmental factors, population differences and access to healthcare.

Why are Nebraska and Kansas seeing more cases?

More than 90% of Nebraska is farmed or ranched, while Kansas also has extensive agricultural activity. That signals that pesticides could be a possible contributor to Parkinson’s risk.

Dr Ayesha Bryant, a functional medicine physician, said that exposure to chemicals through farming could help explain the high rates in Nebraska, Kansas and possibly Arkansas. “The literature repeatedly shows associations between pesticide exposure and Parkinson's disease in epidemiological studies,” she told The Daily Mail.

Parkinson’s develops when dopamine-producing neurons progressively become damaged and die. Since dopamine plays a key role in movement, its loss can lead to tremors, stiffness, and slow movement.

Other pesticides, including paraquat and glyphosate, have also been investigated for possible links to Parkinson’s, although the evidence is not conclusive for all of them.

Air Pollution May Be Another Factor

Only around 20% of Utah is farmed or ranched, and pesticide use is also low. Yet it recorded the third-highest diagnosis rate.

Dr Rebecca Gilbert, neurologist and chief mission officer at the American Parkinson Disease Association, said air pollution is another environmental factor scientists are increasingly investigating. “Scientists are increasingly looking at air pollution as a possible risk factor for Parkinson's and other brain diseases, including dementia,” she said.

Utah's industrial and mining activity could contribute to exposure to fine particulate matter, or PM2.5. Research has increasingly explored whether long-term exposure to air pollution could affect brain health.

Talking about population as a factor, Dr Johnson Moon, neurologist and medical director for neurophysiology at Providence St Jude Medical Center, said that Utah's predominantly white population.

“Census data shows around 87 percent of residents are white – and Parkinson's is diagnosed more often in white populations than in black or Asian groups,” he said.

He added, “Genetic differences may partly explain this, although disparities in access to care and delayed or missed diagnoses among minority groups could also affect the figures.”

The US sees nearly 90,000 new Parkinson’s diagnoses each year, and more than 1.1 million Americans are estimated to be living with the disease. That number is projected to reach 1.2 million by 2030.

Age remains the biggest known risk factor, but genetics, environmental exposures and other factors may interact over decades. But as of now, scientists cannot point towards one definite cause of Parkinson's with certainty.

India is witnessing a shift in its disease landscape. While greater awareness, improved hygiene and national health policies have helped curb communicable and preventable diseases, the country is now facing a growing burden of metabolic conditions such as fatty liver and colorectal cancer, alongside persistent infections including Helicobacter pylori and intestinal worm infestations, health experts said.

The concerns come ahead of the World Congress of Gastroenterology (WCOG) 2026, to be held in India for the first time from September 30 to October 3 at Yashobhoomi, Dwarka, under the theme “Transforming Gastrointestinal Health, Preserving Nature.”

Fatty Liver a Major Concern

Fatty liver disease has emerged as a key metabolic health challenge in India. An AIIMS-led systematic review and meta-analysis found the condition in 38.6 per cent of Indian adults and 35.4 per cent of children. It is closely associated with diabetes, obesity and hypertension and can remain silent until liver damage progresses.

A recent study found that one in four patients with type 2 diabetes has clinically significant fibrosis.

“India is facing an epidemiological shift at this time. We have made significant strides in controlling preventable disease through awareness, vaccinations and improving quality of life, however alongside these we are now seeing metabolic disease on a scale we have never handled before,” said Dr. Pramod Garg, Professor and Head, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi.

“Fatty liver is the clearest example. The disease is easy to find if we look for it, and we become aware only after the patient falls ill. This is a greater challenge than before—we must move away from only treating diseases—we must now actively promote good health,” he added.

To address the rising burden, India included fatty liver disease in its National Programme for Prevention and Control of Non-Communicable Diseases in 2021, followed by guidelines for its detection at the primary-care level.

Colorectal Cancer Cases Growing Among Young

The experts also flagged colorectal cancer as a growing concern, with cases increasingly being seen among younger adults. India recorded 40,430 new cases among men and 24,433 among women in 2022.

“India has never been short of gastroenterologists or technology. What we have lacked is the habit of taking early symptoms seriously. We often misattribute our symptoms to stress or simply overlook them,” said Dr. Govind Makharia, Professor, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi.

“Every time we fail to identify a disease early, we lose the opportunity to potentially modify its natural history. Any symptom that persists beyond two to three weeks should be evaluated,” he added.

Persistent Infections and Chronic Gut Diseases

H. pylori remains widespread and is associated with peptic ulcer disease and gastric cancer. Intestinal worm infections continue to affect children and can contribute to anaemia and undernutrition.

Chronic gastrointestinal conditions such as celiac disease and inflammatory bowel disease (IBD) are also increasingly being recognized in India. Community-based research led by AIIMS found celiac disease in approximately one in 96 people in northern India.

Dr. Vineet Ahuja, Professor, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi, said conditions such as IBD and celiac disease, once considered rare in India, are now regularly encountered in clinical practice.

“Advances in endoscopy, artificial intelligence and microbiome research are improving diagnosis and treatment. The challenge now is to make these advances more widely accessible,” he said.

“With the advent of AI, we potentially stand at a new era of medicine—we must not dismiss it, but learn to adapt to it and improve the quality of care we provide to our patients,” he added.

The experts stressed the importance of early detection and urged people not to ignore persistent gastrointestinal symptoms, blood in the stool, unexplained weight loss or sustained changes in bowel habits. Earlier testing and preventive interventions can help identify and manage several GI conditions before they progress
