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.

A new study in the US has found that millions of military veterans continue to experience suicidal thoughts, yet many of them are not receiving the mental health treatment they need.
Researchers say the findings highlight the urgent need to improve access to mental health services and strengthen suicide prevention efforts, particularly for younger and female veterans.
The study, published in JAMA Network Open, analyzed data from 2,636 US military veterans who participated in the 2025-2026 National Health and Resilience in Veterans Study (NHRVS), a survey conducted between December 2025 and January 2026.

Researchers found that 13.4% of veterans reported having suicidal thoughts within the previous two weeks, while 14% experienced suicidal thoughts during the past year.
Compared with data collected in 2019-2020, the prevalence of recent suicidal thoughts increased from 9% to 13.4%, representing a 49% rise over five years. However, the prevalence of lifetime suicide planning (8%) and suicide attempts (4.9%) remained largely unchanged.
Based on national population estimates, the researchers said:
One of the study's most concerning findings was that a substantial number of veterans reporting suicidal thoughts were not receiving mental health care.
Among veterans who experienced suicidal thoughts in the previous two weeks:
Researchers also observed similar gaps in the use of psychotherapy and psychiatric medications.
The researchers also found that younger veterans and women veterans carried a disproportionately higher risk of suicidal thoughts, suicide planning and suicide attempts.
The authors concluded, "These findings suggest that suicidal ideation has increased among US veterans over the past 5 years, whereas suicidal planning and attempts have not, underscoring the need to strengthen early intervention, treatment engagement, and targeted prevention efforts."
They further added, "A substantial proportion of veterans reporting recent suicidal ideation are not currently engaged in mental health treatment."
The study showed that veterans who used the VA healthcare system as their primary source of care were more than twice as likely to receive mental health treatment compared with veterans receiving care outside the VA.
According to the researchers, this may reflect better access to mental health services within the VA system. However, the findings also indicate that significant treatment gaps remain even among VA users due to barriers like stigma, delayed help, limited availability of services, or other factors.
The study comes as suicide continues to be a major public health issue among US veterans. According to the US Department of Veterans Affairs, more than 6,000 veterans die by suicide each year, and veterans continue to have higher suicide rates than the general US population.

A humanitarian worker has been admitted to a specialist infectious disease unit in London after being potentially exposed to the Ebola virus while working in the Democratic Republic of the Congo (DRC).
UK health officials have stressed that there are no confirmed Ebola cases in the United Kingdom and that the risk to the public remains very low.
The individual, a UK resident involved in treating Ebola patients in eastern DRC, was medically evacuated to London as a precaution and is being monitored in a high-level isolation unit. According to the UK Health Security Agency (UKHSA), the worker is not showing symptoms of Ebola but is under observation because the virus has an incubation period of 2 to 21 days.
The evacuation follows established international protocols for healthcare and humanitarian workers who may have been exposed to highly infectious diseases. Health authorities emphasized that:
Officials are also conducting routine contact assessments where necessary, although no wider public health concerns have been identified.

The admission comes as the Democratic Republic of the Congo is battling one of its most severe Ebola outbreaks in recent history.
The outbreak, declared on May 15, 2026, is caused by the Bundibugyo strain of the Ebola virus, a less common species for which there are currently no licensed vaccines or proven antiviral treatments.
This has made containment significantly more challenging than previous Ebola outbreaks caused by the Zaire strain. According to the latest reports from Congolese health authorities and international agencies:
WHO believes the true number of infections could be two to four times higher because many cases remain undetected in conflict-affected areas.

Recognizing the growing threat, the World Health Organization (WHO) declared the outbreak a Public Health Emergency of International Concern (PHEIC) on May 16, 2026, just one day after the outbreak was officially announced.
WHO warned that the outbreak poses a significant regional and international public health risk due to rapid transmission, cross-border spread, limited access to affected communities, lack of approved vaccines for the Bundibugyo virus and ongoing armed conflict disrupting healthcare operations.
Experts say the current situation should not cause public alarm. The UK's specialist infectious disease units are designed to safely manage suspected cases of high-consequence infectious diseases, and precautionary evacuations of healthcare workers have occurred during previous Ebola outbreaks.
Public health officials stress that:
A U.S. humanitarian worker in the Democratic Republic of the Congo (DRC) had tested positive for Ebola a few days ago.
The U.S. Centers for Disease Control and Prevention (CDC) confirmed, saying it is working closely with the individual's employer, U.S. government health agencies, and Congolese health authorities to prevent further transmission by tracing contacts to identify people who may have been exposed.
According to reports, the infected individual was working for a humanitarian organization in eastern Congo, where the outbreak has continued to spread despite ongoing response efforts.
The CDC has not released details about the patient's identity or condition but emphasized that contact tracing and public health measures are underway.

Research suggests that disruptions in rapid eye movement (REM) sleep, during which we dream, consolidate memory, and process emotions, could be among the earliest biological signs of Alzheimer's disease.
Scientists now believe that changes in sleep are not just a consequence of Alzheimer's, but may actually appear years before primary cognitive symptoms emerge.

The study, published in Alzheimer's & Dementia, studied 128 older adults, including people with Alzheimer's disease, mild cognitive impairment (MCI), and cognitively healthy individuals.
Participants underwent overnight polysomnography, the gold standard sleep test that records brain activity, breathing, heart rate, eye movements, and muscle activity during sleep.
Researchers discovered that participants who took significantly longer to enter REM sleep, known as REM sleep latency, were more likely to have Alzheimer's disease.
These individuals also showed:

Scientists believe REM sleep also supports the brain's "cleaning system," helping remove waste products that accumulate during the day.
When REM sleep is delayed or disrupted, this process may become less efficient, allowing toxic proteins like amyloid-beta to build up over time.
According to Dr. Yue Leng, associate professor in the Department of Psychiatry and Behavioral Sciences at the University of California, San Francisco and one of the study's authors: "Delayed REM sleep may disrupt the brain's ability to consolidate memories by interfering with the process that converts recent experiences into long-term memories. If this is insufficient because REM sleep is delayed or shortened, it could increase the stress hormone cortisol. This may impair the brain's hippocampus, a critical structure for memory consolidation."
Commenting on the findings, Dr. Jocelyn Cheng, neurologist and Senior Director of Neuroscience Clinical Research at Eisai U.S., said:
"The relationship may be bidirectional. Delayed REM may contribute to Alzheimer's-type changes, and/or Alzheimer's itself may result in prolonged REM latency."
The new findings offer a possible biological explanation. Researchers suggest that the accumulation of amyloid may interfere with the brain's internal clock and its ability to regulate normal sleep cycles, creating a vicious cycle where poor sleep accelerates brain changes linked to Alzheimer's.
Researchers say future studies should examine whether improving REM sleep through better sleep hygiene or treatment of conditions such as sleep apnea could help slow or delay Alzheimer's-related brain changes.
Experts recommend maintaining a regular sleep schedule, limiting alcohol before bedtime, reducing evening screen exposure, and seeking medical evaluation for persistent sleep disorders.
