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.

The ongoing Ebola outbreak in the Democratic Republic of Congo (DRC) continues to expand, with the virus spreading to three new health zones in North Kivu and Ituri provinces, according to government officials.
The country, which is battling its 17th Ebola virus disease outbreak, has now recorded 676 confirmed cases and 136 deaths, Health Minister Dr. Samuel-Roger Kamba said in a post on social media platform X.
Kamba informed that the virus has spread to three new health zones in the country. They are:
Masereka (North Kivu)
Vuhovi (North Kivu)
Kambala (Ituri)
“#EbolaBundibugyo: As of June 10, 676 cumulative confirmed cases — 629 in Ituri, 44 in North Kivu, 3 in South Kivu. Forty-one new cases reported today,” Kamba wrote.
“Three new health zones affected: Masereka and Vuhovi in North Kivu, Kambala in Ituri. Our teams are adapting, surveillance is intensifying. The response follows every signal, in every zone,” he added.

The outbreak, caused by the rare Bundibugyo strain of the Ebola virus, was officially declared on May 15.
There is currently no approved vaccine or specific treatment for this strain.
The minister also reported total 10 recoveries from the deadly disease.
“#EbolaBundibugyo: Two newly recovered today in the Bunia Health Zone. They are returning home. Every recovery is a victory, a message of hope for our communities. Come get treated quickly — early care saves lives,” Kamba said.

Meanwhile, the Ebola outbreak has also disrupted the preparations of the Democratic Republic of Congo national football team ahead of the FIFA World Cup.
The squad arrived in the United States after spending three weeks in isolation in Europe due to the outbreak in their home country. US authorities required the team to complete the quarantine period in Belgium before being allowed to enter the country, AFP news agency reported.
DRC cancelled a planned pre-tournament training camp at home and instead based preparations in Belgium.
In addition, a scheduled warm-up match against Chile in Spain was also cancelled over concerns about the spread of the virus.
“We adapted to the situation,” said head coach Sebastien Desabre. “We had to focus, as we have had to adapt often.
“That is what we did. We worked well, we played two tough friendlies, and here we are. Now, it is another step for us.”
The team will be based in Houston during the tournament and is scheduled to play its opening Group K match against Portugal on June 17.
Ebola is a severe and deadly disease caused by a virus mostly found in Africa. The spread of the disease happens through contact with infected body fluids.
Symptoms includes fever, headache, weakness, vomiting, diarrhea, muscle pain, sore throat, and unexplained bleeding. This eventually leads to severe complications like bleeding, organ failure, and death.
Ebola is a highly lethal viral hemorrhagic fever first identified in 1976. Over the past five decades, it has caused over 30 outbreaks, primarily in Central and West Africa. The virus takes its name from the Ebola River in the Democratic Republic of the Congo (DRC).
Three strains of the virus — Ebola virus, Sudan virus, and Bundibugyo virus — have caused the largest outbreaks in Africa. Among them, the Ebola virus is considered the deadliest, with fatality rates reaching up to 90% without treatment.

Researchers at the Indian Institute of Technology Madras (IIT Madras) have released the world’s most detailed 3D atlas of the human brainstem.
Called ANCHOR (Atlas of Neurochemical Characterization of the Human Brainstem with 3D Reconstruction), the atlas was developed using a high-throughput brain imaging and computing platform that transforms whole human brains into 3D cell-resolution atlases.
It provides comprehensive multi-modal 3D maps of the human brainstem across the lifespan, covering the prenatal period, childhood, and adulthood.
The atlas includes more than 200 brainstem nuclei and fiber tracts reconstructed from hundreds of serial sections. To identify distinct neurochemical cell types, researchers overlaid eight complementary immunostains across more than 500 sections, enabling detailed mapping.
Developed by the Sudha Gopalakrishnan Brain Centre (SGBC) at IIT Madras, ANCHOR has been made publicly available to researchers, clinicians, and patients worldwide.
“This is a significant accomplishment in the field of neurobiology. This is a multimodal framework integrating MRI, histology, and detailed chemo-architecture. It will be the most detailed and comprehensive maps of the human brainstem, and made available publicly in digital form. These maps will help in identifying specific cell populations affected in brain stem lesions, which could be critical for clinical applications,” said Prof. Ajay Kumar Sood, Principal Scientific Adviser to the Government of India, during the 3rd BRICS Neuroscience Symposium 2026.
Prof. Mohanasankar Sivaprakasam, Head of SGBC, IIT Madras, said the atlas uses a multimodal image visualization framework that integrates volumetric MRI data with cellular-level images.
“By establishing precise spatial correspondence across these modalities, the atlas enables a seamless transition from gross brain structures in the MRI to cellular-level features. We envision that these maps and atlases will have significant implications for neuroscience and neuromedicine,” he said.
The human brainstem contains more than 200 nuclei and fiber tracts and plays a vital role in regulating essential body functions.
ANCHOR is an online platform featuring more than 800 serial histological sections stained for Nissl and seven immunochemical (IHC) markers from three human brainstems representing different stages of life:
The atlas also describes catecholaminergic groups across all three age groups, identifies the protoplasmic commissural dendrites of the hypoglossal nucleus, and describes the pretectal nuclei in the fetal brainstem.

The National Institute of Virology (NIV) in Pune has confirmed Nipah virus infection in a 43-year-old man from Ramanattukara in Kerala's Kozhikode district.
The patient, who was earlier shifted from a private hospital to a dedicated Nipah isolation facility at Kozhikode Government Medical College Hospital, remains in critical condition and is currently on ventilator support under the close supervision of a team of specialists, as per officials.
The patient was initially transferred to the Medical College Hospital after testing positive in a preliminary examination conducted at the Virus Research and Diagnostic Laboratory (VRDL). Following preliminary test results that suggested Nipah infection, the Kerala Health Department swung into action and intensified surveillance and containment measures in Kozhikode district.
After confirmation from NIV Pune, health authorities launched extensive contact-tracing efforts. District officials have identified 77 people who may have been exposed to the patient through contact tracing:
Notably, the patient's immediate family members—including his wife, two children, father, and mother—have been placed under quarantine.
In addition, two staff members of a private hospital in Kozhikode who interacted with the patient during earlier treatment have also been advised to remain in quarantine. Samples from five primary contacts have been sent to the VRDL laboratory for testing, as per media reports.

As per District Collector M.S. Madhavikutty, none of the identified contacts are currently showing symptoms and there is no immediate need to declare a containment zone.
Health Minister K. Muraleedharan also stated that the current situation does not warrant the declaration of a containment zone in Ramanattukara.
"The 15 priority contacts have been advised to remain in quarantine. A rapid response team meeting was held to ensure the availability of PPE kits and gloves. There is no shortage of medicines, and additional supplies will arrive from Chennai," the minister said.
The patient's initial symptoms included a high fever about a week ago and was later hospitalized with symptoms suggestive of encephalitis. But as his condition worsened, doctors tested for Nipah infection, which turned positive.
He is likely to have been exposed to the virus while cleaning an old godown in Puthukad, Malappuram district, reportedly connected to his soap manufacturing business.
Another likely source of infection is a chikoo tree located on the patient's property, where officials have reportedly observed the presence of bats and bird droppings.
"Anyone developing fever should voluntarily isolate themselves, wear a mask, and avoid close contact with others. However, making masks mandatory for the public is not being considered at present, as the situation does not require such a measure," Madhavikutty told reporters.
This is the 11th Nipah outbreak reported in Kerala since the virus was first detected in the state in 2018.
According to the World Health Organization, Nipah virus is a zoonotic disease, meaning it can spread from animals to humans. It can also be transmitted through contaminated food and, in some cases, directly from person to person.
In humans, infection can range from asymptomatic illness to severe respiratory disease and fatal encephalitis (brain inflammation). The virus can also infect animals such as pigs, causing significant economic losses for farmers.
Although outbreaks have been limited mainly to parts of Asia, the virus is known for its high fatality rate and potential to cause severe disease.
Common symptoms include:
Nipah virus is considered a major public health threat because of:
