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.
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.

Reducing sugar intake during pregnancy and the first two years of a child’s life could have life-changing benefits for brain health, particularly in lowering the risk of Alzheimer’s disease.
According to a new study, limiting sugar intake could reduce the risk Alzheimer’s by more than 45% in the future.
The research, published in npj Aging, found that people exposed to lower sugar intake during the first 1,000 days of life, from conception until age two, had a 46% lower risk of Alzheimer’s disease, a 27% lower risk of dementia, an 11% lower risk of depression, and a 20% lower risk of anxiety in later life.
Researchers analysed health and brain imaging data from more than 60,000 participants in the UK Biobank.
They used Britain’s World War II sugar rationing period as a natural experiment, comparing people born when sugar availability was restricted with those born after rationing ended.
Scientists say that early life is a critical phase for the brain, metabolism, and immune system. Nutrition during this period can shape long-term health, influencing disease risk of neurodegenerative disease decades later.
“Our findings suggest that limiting sugar intake during the first 1,000 days of life may have long-lasting benefits for brain health,” the researchers noted, adding that the effects appear to persist well into older adulthood.
Dr. Bing Zhang, a geriatric medicine researcher involved in the study, said the results support the idea that nutrition in early life can shape lifelong brain health through metabolic programming during critical stages of development.
The study also found key structural differences in the brain. MRI scans showed that participants who had lower sugar exposure early in life had brains that appeared approximately 0.4 years younger biologically.
Their brains showed greater grey matter volume and fewer signs of white matter damage that is often linked to healthier cognitive ageing.
The researchers found an association, not proof that sugar directly causes Alzheimer’s or dementia. Since the study is observational, other factors like overall diet, access to healthcare facilities and services, and lifestyle may also have contributed to the findings.
Dr. Sara Rodrigues of Alzheimer’s Research UK, who was not involved in the research, cautioned that while the results are compelling, they do not establish cause and effect. However, they add to the growing evidence that healthy eating throughout life plays an important role in maintaining brain health.
This comes after a recent study suggested that children who who consume higher amounts of ultra-processed foods may already be showing subtle changes in the way their bodies regulate insulin, potentially increasing the risk for type 2 diabetes in the future.
According to a new study published in the journal Nutrients, children who have higher amounts of in ultra-processed foods (UPFs) had reduced insulin sensitivity and higher insulin secretion, even though they did not have diabetes.
Researchers from Texas A&M University–San Antonio, University of Texas Health San Antonio, University of Texas Rio Grande Valley, and Wake Forest University School of Medicine discovered that the metabolic changes linked to diabetes may begin much earlier in life than previously thought.

The Democratic Republic of the Congo’s (DRC) Ebola outbreak has become the second-largest Ebola epidemic ever recorded, overtaking the country’s devastating 2018-2020 outbreak.
The current epidemic has also underscored the growing global concern over the rapid spread of the deadly disease.
According to the latest official figures released by the DRC health authorities and the European Centre for Disease Prevention and Control (ECDC), the country has reported 3,442 confirmed Ebola cases and 1,521 deaths as of July 29, 2026.
However, more recent updates indicate the outbreak has continued to worsen rapidly, with 3,532 confirmed cases and 1,556 deaths reported by July 31, 2026.
The only Ebola outbreak larger than the current epidemic remains the 2014-2016 West Africa outbreak, which infected more than 28,000 people and resulted in the deaths of over 11,300 lives.
Unlike many previous Ebola outbreaks caused by the Zaire ebolavirus, the ongoing epidemic is caused by the Bundibugyo virus, a rarer species of Ebola virus for which there is currently no approved vaccine or licensed treatment.
The World Health Organization (WHO) said the outbreak remains active with heightened community transmission, particularly in eastern DRC, where insecurity, mistrust, population displacement and limited healthcare access continue to hamper outbreak containment efforts.
In its latest Disease Outbreak News update, WHO said, “The outbreak remains active, with sustained transmission.”
The UN health agency noted that inside conflict, population displacement, community mistrust and restricted access to affected areas continue to affect contact tracing, surveillance, and containment and treatment activities.
WHO has also stressed that although the global risk remains low, the regional risk is high because of frequent cross-border movement between the DRC and neighbouring countries.
A major challenge in controlling the epidemic is the absence of a licensed vaccine or targeted therapy against the Bundibugyo virus.
According to WHO, while the Ebola vaccine used against the Zaire strain has shown limited experimental cross-protection in animal studies, there is currently inadequate evidence to recommend its use against Bundibugyo virus disease.

Amid the worsening outbreak, researchers have reached an important milestone in Ebola vaccine development.
The first volunteer has received an experimental vaccine targeting the Bundibugyo strain of Ebola, marking the world's first Phase I clinical trial for this virus, according to the University of Oxford.
The vaccine, ChAdOx1 BDBV, developed in collaboration with Serum Institute of India (SII), is designed specifically to protect against the Bundibugyo strain of Ebola.
It uses the same viral vector platform that powered the Oxford-AstraZeneca COVID-19 vaccine.
The vaccine uses a genetically modified chimpanzee adenovirus (ChAdOx1)—a harmless virus that normally causes the common cold in chimpanzees—as a delivery vehicle.
"We welcome the start of the phase 1 clinical trial of an investigational vaccine against Ebola Bundibugyo virus disease—an important step to assess the safety and immune responses generated by the vaccine," said WHO Director-General Tedros Adhanom Ghebreyesus on X.
Health authorities, supported by WHO, Africa CDC and international partners, continue to strengthen surveillance, laboratory testing, infection prevention, community engagement and patient care.

The growing popularity of GLP-1 weight loss drugs like Ozempic, Wegovy and Mounjaro has brought another side effect into focus.
After the widely discussed 'Ozempic Face,' dermatologists are now warning about 'Ozempic Hair,' a term used to describe excessive hair shedding that can occur after rapid and weight loss.
Experts say the condition is not caused by the medication directly damaging hair follicles. Instead, it is largely linked to rapid weight loss, nutritional deficiencies, and the body's metabolic response to sudden calorie restriction.
According to Dr. Gaurav Garg, Senior Dermatologist, Hair Transplant Surgeon, Dermato-Surgeon and Medical Director at Dermalife Skin and Hair Clinic, New Delhi, cases have become increasingly common in dermatology clinics.
"We are seeing a significant rise in patients complaining of excessive hair shedding after taking GLP-1 weight loss medications. Around 40% of the weight loss drug users visiting our clinics are experiencing mild to significant hair loss, with many noticing hair falling out in large clumps while washing or combing. In most cases, the medication itself is not directly damaging the hair. The problem is rapid weight loss, nutritional deficiencies and the metabolic shock experienced by the body," Dr. Garg said.
He added that the increasing use of these medications without proper medical supervision is further contributing to the problem.
"Ozempic isn't the enemy of your hair; malnutrition and metabolic shock are. By ensuring gradual weight loss and proper nutritional support under expert guidance, many of these problems can be prevented," he said.

'Ozempic Hair' is not a medical diagnosis but a popular term for telogen effluvium, a temporary phase of hair loss due to stress. Rapid weight loss acts as a physical stressor, causing a larger number of hair follicles to enter the resting phase prematurely.
Hair shedding usually becomes noticeable three to four months after a user starts taking GLP-1 drugs. Reduced appetite during treatment may also result in deficiencies of all the nutrients that are important for hair growth. For example, protein, iron, zinc and biotin.
Dr. Garg cautioned that weight loss injections are increasingly being used for cosmetic purposes rather than for legitimate medical conditions.
"One of the biggest concerns today is that these weight loss injections are increasingly being viewed as quick-fix cosmetic solutions rather than prescription medicines meant for specific medical conditions. Many people begin taking them after watching social media content or on the advice of friends, without understanding the nutritional consequences. Hair shedding in most cases is temporary, but prevention is always better than treatment. These medications should never be used casually or without expert supervision," he said.
He stressed that people undergoing medical weight loss should receive appropriate dietary counselling, consume adequate protein, and undergo regular monitoring to reduce nutritional complications.
Echoing these concerns, Dr. Ramanjeet Singh, Director, Department of Dermatology, Medanta Hospital, said the trend reflects the risks of unsupervised use of GLP-1 medications.
"The emerging trend of 'Ozempic Hair' highlights the risks associated not only with rapid weight loss but also with the indiscriminate use of these medications without proper medical evaluation. We are increasingly seeing individuals obtaining weight loss drugs without specialist consultation or using them beyond recommended doses in pursuit of faster results. Hair shedding in such cases usually represents telogen effluvium triggered by rapid metabolic changes and nutritional deficiencies rather than permanent damage to the hair follicles," Dr. Singh said.
He added that the condition is generally reversible with timely intervention, balanced nutrition and medically supervised weight management.
Dermatologists advise people considering prescription weight loss medications to undergo a medical evaluation before starting treatment.
Maintaining adequate protein intake, avoiding crash diets, correcting iron and vitamin deficiencies where necessary, and seeking early dermatological care if excessive hair shedding develops may help reduce the severity and duration of hair loss.
