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.

Millie Bobby Brown has built an impressive career, all while quietly managing a few health concerns along the way. From becoming a household name through Netflix’s hugely popular Stranger Things to leading films like Enola Holmes, the Gen Z actor (now a married mother of one) has made a strong mark in Hollywood. What many people may not realise is that her work has, at times, been shaped by a hearing-related condition. Brown has lived with hearing loss for most of her life, a fact that often goes unnoticed.
Brown first spoke publicly about her hearing condition in a 2017 interview with Variety, where she shared that she has had hearing loss in one ear since birth. Even early in her career, she was clear that she would not allow it to stand in the way of her passion for performing. “I just started to sing, and if I sound bad I don’t care, because I’m just doing what I love,” she said at the time. “You don’t have to be good at singing. You don’t have to be good at dancing or acting. If you enjoy it and it makes you happy, you should do it.”
While Brown rarely focuses on her hearing loss, she has spoken about how it affects her daily life. In a conversation with Call Her Daddy host Alex Cooper, she explained that certain sounds, like loud chewing, do not bother her because she can mostly hear herself when she eats. She also shared that her husband, Jake Bongiovi, whom she married in 2022, sometimes jokes that she has “selective hearing.” In reality, she says sounds often feel “muffled, like being underwater.” Brown admitted that she does miss important moments, including hearing directors call out “action” or “cut” on set.
Unilateral hearing loss happens when hearing is affected in one ear while the other ear functions normally. Even with hearing in one ear, this condition can make it difficult to understand speech clearly and to identify where sounds are coming from.
The level of hearing loss in one ear can range from mild to severe. When there is little to no hearing at all in one ear, it is described as severe or profound hearing loss, also known as single-sided deafness. Unilateral hearing loss may be present at birth, develop gradually, or appear suddenly. Depending on the cause, options such as hearing aids or cochlear implants may help improve hearing, according to the Cleveland Clinic.
Many symptoms of unilateral hearing loss are similar to those seen with hearing loss in both ears. You may:
Doctors do not yet fully understand all the reasons why hearing loss occurs in just one ear. Causes can differ between adults and children. In children, hearing loss may be linked to genetics or infections. Possible causes include:
According to the American Academy of Audiology, treatment depends on the underlying cause and the severity of the hearing loss. Available options may include:

In what researchers are calling an important scientific advance, a team in the US has shown through animal experiments that Alzheimer’s disease may be reversible, overturning a belief that has shaped medical thinking for more than 100 years. For generations, the neurodegenerative condition was considered permanent and progressive. The findings, published in Cell Reports Medicine, are based on multiple preclinical mouse models as well as examinations of human Alzheimer’s brain tissue.
The study found that preserving a healthy balance of NAD, a molecule central to cellular energy production, could both prevent and reverse Alzheimer’s-related damage. NAD plays a key role in brain function and is now seen as a major contributor to the disease process. Researchers also observed that NAD levels drop much more sharply in the brains of people with Alzheimer’s, a pattern that was mirrored in mouse models of the condition.

“We were extremely encouraged by what we observed,” said Andrew A. Pieper, the study’s senior author and Director of the Brain Health Medicines Center at the Harrington Discovery Institute, University Hospitals, as per Sciencedirect. “By restoring the brain’s energy balance, we saw both structural and functional recovery in mice with advanced Alzheimer’s.”
Pieper noted that the effect appeared consistently across two very different mouse models, each driven by separate genetic mechanisms linked to Alzheimer’s in humans. “Seeing recovery in models caused by distinct genetic pathways strengthens the case that restoring NAD balance in the brain could have real therapeutic potential for patients,” he said.
For the study, researchers examined mice engineered to carry genetic mutations known to cause Alzheimer’s disease in people. One group of mice carried multiple human mutations affecting amyloid processing, while the second group carried a human mutation in the tau protein.
After confirming that brain NAD levels dropped sharply in both human Alzheimer’s tissue and mouse models, the team tested whether stopping this decline before symptoms appeared could prevent disease, and whether restoring NAD levels after the disease had progressed could reverse it. To do this, they used a well-studied drug called P7C3-A20 to restore NAD balance in the brain.
The results were striking. Not only did maintaining NAD levels prevent Alzheimer’s from developing in mice, but starting treatment later, after the disease was already advanced, allowed the brain to repair the main pathological damage caused by the genetic mutations. In both mouse models, cognitive abilities were fully restored.
In Alzheimer’s disease, NAD, short for nicotinamide adenine dinucleotide, is an essential coenzyme whose levels naturally decline with age. This decline disrupts energy production, mitochondrial health, DNA repair, and the ability of neurons to withstand stress. Research suggests that increasing NAD levels, often through precursors such as nicotinamide riboside, may reverse Alzheimer’s-related damage, improve memory, and correct abnormal RNA processing in animal models. Because of this, NAD has become a major area of focus for developing new Alzheimer’s therapies, according to the National Institutes of Health.
The findings also pave the way for further research and eventual testing in people. The technology behind the treatment is currently being developed for commercial use by Glengary Brain Health, a Cleveland-based company co-founded by Dr. Pieper.
“This recovery-based treatment approach now needs to be tested in carefully designed clinical trials to see if the benefits seen in animals can be replicated in humans,” Pieper said.
He added that future laboratory work will focus on identifying which components of brain energy balance matter most for recovery, exploring additional strategies that could complement this approach, and determining whether similar methods could work for other long-term, age-related neurodegenerative diseases as well.

Adenovirus, or what some people are calling the mystery disease is going to be the next worry in the UK, after superflu had already grappled the healthcare system. Along with H3N2 and its variant superclade K, people are now worrying about this mystery disease.
Adenovirus is highly contagious and causes mild cold or flu-like symptoms, though severe cases could lead to stomach flu and vomiting. Many describe this virus as 'heartier' than others. The reason is that the virus can survive longer on surfaces and even resist the common disinfectants used. This is what makes it highly transmissible.
As of now, there is no treatment for adenovirus, it could however be managed and monitored. What helps is regular handwashing and thorough cleaning of surfaces.
The good news is that cases of adenovirus are actually dropping in the UK, as confirmed lab reports. The cases last week were 1.2 per cent, whereas the week prior, it was at 1.7 per cent, as also reported by the Independent.
While a lot of the symptoms mimics of those in flu or COVID, including shortness of breath, a sore throat and or a runny nose. However, there are certain unique symptoms of adenovirus that include:
Other rare symptoms could also include impact on your bladder or nervous system. As viruses in your bladder can also cause urinary tract infections, and the same virus in your nervous system can cause condition that can affect your brain. These conditions also include encephalitis and meningitis.
The symptoms usually start to subside within two days, however, if the symptoms stay even after three days without any relief, it might be a red flag. The best thing to do during such a situation is to go consult your GP.

Experts have noted that due to its ability to stay longer in the environment and being highly transmissible, it is in fact, spreading faster than flu and COVID. Eric Sachinwalla, Jefferson Health's medical director said that this virus is still unfamiliar and thus not much can actually be done to treat adenovirus. Speaking to PhillyMad, he said, "It is pretty contagious because it is heartier than other viruses - soap and water, or everyday disinfectant, won't kill it, so it tends to live in the environment longer."
Since adenovirus spreads through close contact and is resistant to many everyday disinfectants, hygiene remains the key. The best way to stay safe is by avoiding close contact, especially with those who are unwell. You may also keep an eye on your symptoms, including your body temperature and take steps to prevent the virus from spreading by taking precautions, as well as getting the flu jab.
