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.

The Department of Health (DOH) reported 411 measles infections in Philippines' Northern Mindanao in 2025, which was a 11% increase from 371 cases in 2024. Health officials are now warning people that the situation may get worse in 2026, as rate of unvaccinated children in the region also rise.

In 2025, 75% of the patients were unvaccinated.

In order to prevent outbreaks, DOH-Northern Mindanao and local health offices said that they will be deploying teams to administer Measles-Rubella (MR) vaccines to children and people aged six to 59.

“There are (measles) outbreaks in various parts of the country because of low (immunization) coverage and that includes our region,” said Germaine Labadan, head of the DOH-X Family Health Cluster.

In 2025, only 56.7% of Northern Mindanao's eligible population received MR shots, which led to a herd immunity well below the target of 95%.

Cagayan de Oro, a highly urbanized city, recorded the region’s highest measles-rubella (MR) coverage at 87.21%, while Bukidnon lagged at 49.71%. Coverage in other areas remained low, with Misamis Oriental at 51.87%, Misamis Occidental at 52.05%, Iligan at 52.55%, and Camiguin at 53.73%.

As part of this year’s Measles-Rubella Supplemental Immunization Activity (MR-SIA), children will be given booster MR vaccines along with Vitamin A supplements. The 21-day campaign will run from January 19 to February 13.

“This is open to all eligible, regardless of the immunization status of the child because the vaccine serves as a booster,” Labadan said. This also includes children who completed the first and second doses. “Parents may present the immunization booklet, but it is not necessary because all will be given a new one,” she said.

What Is Measles?

Measles, also known as rubeola, is a highly contagious viral illness that typically causes fever, cough, a runny nose, red and watery eyes, and a distinctive red, blotchy rash that usually begins on the face and spreads downward. The virus spreads through the air when an infected person coughs or sneezes and can lead to serious complications such as pneumonia or brain inflammation. Despite its severity, measles is preventable through a safe and effective vaccine, as per the Mayo Clinic.

How Contagious Is Measles?

Measles is among the most contagious diseases in the world. The virus spreads through airborne droplets that can linger in the air or on surfaces for hours. Up to 90% of unvaccinated people who are exposed to measles will become infected. A single infected person can pass the virus to an estimated 12 to 18 others through close contact or shared spaces. People can transmit the virus days before symptoms become obvious and continue spreading it after the rash appears, according to the World Health Organization.

How Long Is Someone Contagious With Measles?

Someone infected with measles can spread the virus from four days before the rash develops to four days after it appears. The virus spreads so efficiently that about 90% of people who are unvaccinated or have never had measles will become infected after being exposed.

In November, Canada lost its measles elimination status following a significant outbreak, according to the Pan American Health Organization, which works closely with the World Health Organization.

“It’s important to say that all the other 34 countries in the region, they keep their certification as measles-free,” said PAHO/WHO Director Dr. Jarbas Barbosa at the time, as per NPR News.

U.S. health officials have also warned that genetic links between outbreaks in different states suggest continued spread.

“The trajectory that we’re looking at now is that we do anticipate more cases well into January,” Bell said. “What that means for us nationally in terms of how they are defining our designation in this country as having eliminated measles is unclear.”

Nipah virus case detected in India's West Bengal, where two nurses are suspected of being infected by the virus. The case has come 24 kilometers away from West Bengal's capital, Kolkata, in North 24 Parganas' Barasat, where the patients are on a life support at a private hospital.

The blood samples collected from the nurses, one male and one female, were sent to the Virus Research and Diagnostic Laboratory, ICMR, at the All India Institute of Medical Sciences (AIIMS) in Kalyani, which is around 50 kilometers north of Kolkata in Nadia. Another report has been sent to Swasthya Bhawan, the state health department headquarters. The two nurses one from Nadia's Kalyani and another from East Burdwan's Katwa, work at the same hospital where the have been admitted.

Reports say that the nurses went home to Katwa around 10 days back, from where they may have caught the illness. The female nurse was initially admitted to a hospital in Katwa, later moved to Burdwan Medical College. Her condition kept worsening, this is when she was admitted in Barasat's private hospital, she is currently in the ICU. The male nurse is also on the ventilator support. Both patients are kept in isolation.

Update On The Nipah Virus Spread By West Bengal's Health Authorities

The sources from Swasthya Bhawan said that officials were handling the situation with extreme alarm as Nipah virus has a high rate of mortality and could spread rapidly. The Telegraph reported that top health officials form Union health ministry, including Union health secretary are in touch with Bengal chief secretary Nandini Chakravarty and state health secretary Narayan Swarup Nigam.

The health department has now begun contract tracing in Nadia, East Burdwan, and North 24 Parganas.

Chakravarty also asked people to not panic and remain alert, while avoiding to spread misinformation and follow hygiene practices. The State government has also launched three helpline numbers — 03323330180, 9874708858, 9836046212 — for public queries.

Union Health Minister JP Nadda also wrote to West Bengal's Chief Minister Mamata Banerjee, assuring full support from Centre. Banerjee too visited the hospital late on Sunday night.

What Is Nipah Virus?

As per the World Health Organization (WHO), Nipah virus infection is a zoonotic illness that is transmitted to people from animals, and can also be transmitted through contaminated food or directly from person to person.

In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.

Although Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people.

During the first recognized outbreak in Malaysia, which also affected Singapore, most human infections resulted from direct contact with sick pigs or their contaminated tissues. Transmission is thought to have occurred via unprotected exposure to secretions from the pigs, or unprotected contact with the tissue of a sick animal.

In subsequent outbreaks in Bangladesh and India, consumption of fruits or fruit products (such as raw date palm juice) contaminated with urine or saliva from infected fruit bats was the most likely source of infection.

Human-to-human transmission of Nipah virus has also been reported among family and care givers of infected patients.

Nipah Virus Symptoms

• Fever
• Headache
• Breathing difficulties
• Cough and sore throat
• Diarrhea
• Vomiting
• Muscle pain and severe weakness

Wondering when you are most at risk of having a heart attack?

Dr Srihari Naidu, a triple board-certified in internal medicine, cardiology and interventional cardiology and cardiology professor at New York Medical College says that the winter season is when we're most susceptible to attacks.

He told HealthandMe: "Major cardiovascular studies have shown a link between cold exposure, including the drop in temperature during the winter months, and risk of heart attack. While it’s hard to pin point the exact reason, it is clear that cold exposure does make the heart work harder."

Heart attacks are one of the leading causes of death in the country. Four Indians experience a heart attack every minute, with one in four dying of the cause.

Experts have also noticed a rising trend of nearly 50 percent of heart attack patients being under the age of 40, with half of all heart attacks in Indian men occurring under 50.

Why Are Your More Likely To Have Attack In Winters?

According to Dr Naidu, falling temperatures can cause arteries to narrow, reduce oxygen flow and force the heart to work harder. This can lead to the thickening of blood and with time, cause a heart attack.

"For one thing, cold causes all the arteries in the body to constrict, so that more blood flow is in the central parts of the body like the gut and less on the surface where heat can be lost through the air. While this prevents hypothermia, it makes the heart work harder and need more oxygen itself. In addition, cold causes blood to be thicker, a phenomenon that could increase the risk of blood clots.

"This combination of the heart working harder, needing more oxygen and the blood being more prone to clotting results in a higher rate of heart attacks. In addition to this, people who already have blockages will experience more chest pain (angina) in the cold due to the heart working harder, and if this is tied to extra exertion, that risk could skyrocket."

Additionally, Dr Tamil Selvan Muthusamy, Consultant Cardiologist at Cardiac Vascular Sentral Kuala Lumpur (CVSKL) told HealthandMe: "Extreme pollution, winter illnesses like the flu can cause inflammation that can trigger heart problems and holidays activities can put extra strain on the heart when it's already working overtime from the cold."

Apart from this, Dr Y. Vijayachandra Reddy, Senior Consultant Cardiologist, Apollo Hospitals, Greams Road Chennai, also noted that hypertension, chest infections and excessive holiday drinking as well as smoking can worsen the risk of heart attack during this season.

He shared with the publication: "Chest infections and throat infections are quite common in the winter season. Intercurrent flu or other chest infections can cause an inflammatory milieu, which can lead to more ruptures of the cholesterol or atherosclerotic plaques in the blood vessels of the heart, leading to sudden precipitation of heart attacks.

"The holiday syndrome, wherein in the winter season, many holidays, weekends and people can take recourse to excessive recreational use of alcohol or smoking, which can lead to trouble."

Who Is Most At Risk?

Dr Naidu warns people who have a history of heart disease and other chronic conditions may be most at risk of having a heart attack and should attempt to maintain their body temperature to keep their heart safe and functioning.

"Taken together, people should understand that their baseline risk of a heart attack goes up significantly in the cold weather, especially if they have risk factors for heart disease such as smoking, high cholesterol, diabetes or hypertension, and should take precautions or simply avoid exercise or exertion in the cold weather.

"If any exertion is needed, dressing warmly to make sure the heart doesn’t have to work so hard to maintain body temperature should reduce risk. Most importantly, though, listen to your body, especially in the cold weather, as just being in the cold is a significant stress especially as we get older," he explained to the publication.

To prevent infection-caused heart attacks, Dr Reddy advises: "One of the protective mechanisms is for the vulnerable population to take annual flu vaccine and a lifetime pneumococcal vaccine."

Coronary Artery Disease: The Silent Killer

Coronary artery disease (CAD) is one of the most common illnesses that can cause a heart attack in people. It develops over years and has no clear signs and symptoms apart from a heart attack.

The illness begins due to a buildup of fats, cholesterol and other substances known as plaque in and on the artery walls.

Over time, this can cause narrowing or blockage of the coronary arteries and block the supply of oxygen-rich blood to heart which can lead chest pain (angina), shortness of breath and ultimately, heart attacks.

Typically, those above the age of 45, having a biological family member with heart disease, lack of sleep, smoking, consuming saturated fats along with other autoimmune diseases such as lupus and rheumatoid arthritis can increase the risk of developing CAD.

Nearly one in 10 Indian adults suffer from CAD and about two million people die from the disease annually. Apart from this, about 18 to 20 million American adults aged 20 and older are also affected about the disease.
