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.

A Phase 1 randomised clinical trial of a new Nipah virus vaccine, led by researchers in the US, is offering fresh hope for preventing this deadly infection. The study found that all three doses and vaccination schedules of the candidate vaccine, called HeV-sG-V, were safe and successfully triggered an immune response. These findings were published in the medical journal The Lancet.

The World Health Organization has identified Nipah virus as a high-priority pathogen because it can be fatal in up to 82 percent of cases and currently has no approved treatment or preventive vaccine. The virus is mostly seen in parts of Southeast Asia.

What Is Nipah Virus?

Nipah virus, or NiV, is mainly spread by fruit bats but can also pass through pigs and other animals. It can lead to serious illness and death, and there is currently no medicine or vaccine available to treat or prevent it. According to the Cleveland Clinic, the virus is most commonly reported in Asia, especially in Bangladesh and India.

The virus can spread when:

• People or animals come into contact with bodily fluids such as blood, urine, stool, or saliva from an infected animal.
• People consume food that has been contaminated by an infected animal.
• People are in close contact with someone who has Nipah virus, often while caring for them.

The most effective way to reduce the risk of Nipah virus infection is to avoid contact with sick animals, particularly bats and pigs, in regions where the virus is known to circulate. This also means avoiding foods that could be contaminated, such as raw date palm sap or partially eaten fruit. Since Nipah can spread from person to person through bodily fluids, extra caution is advised when interacting with infected individuals.

Lancet Study Reveals New Nipah Vaccine Is Safe

A Phase 1 randomised clinical trial of a new Nipah virus vaccine has raised hopes that prevention may soon be possible. The trial showed that the vaccine was safe and produced an immune response, according to findings published on December 13 in The Lancet.

“The induction of antibodies within one month of vaccination, along with the sustained response seen with two doses, suggests this vaccine candidate could be useful both during outbreaks and for preventive purposes,” said researchers from Cincinnati Children’s Hospital Medical Center, which led the study, as per NDTV,

Scientists from the Indian Council of Medical Research–National Institute of Virology in Uttar Pradesh described the results as a “milestone” in Nipah vaccine development in an accompanying editorial published in The Lancet. The Phase 1 trial involved 192 healthy volunteers between the ages of 18 and 49.

The study found that a single dose did not produce a strong enough immune response. However, two doses were effective, with the strongest antibody responses seen in participants who received two 100-microgram doses of HeV-sG-V given 28 days apart.

The most common side effect reported was mild to moderate pain at the injection site. No serious side effects, hospital admissions, or deaths were reported during the trial. In their editorial, ICMR-NIV experts noted that the vaccine should next be tested in a larger Phase 2 trial to better understand its safety profile and determine how much protection it can actually provide.

Flu A, or the new version of the flu virus called H3N2 is spreading quickly, the worst part is that fewer people are getting the flu shots. Doctors and scientists say that this year's influenza season could be tougher than the usual. Dr. Amanda Kravitz, a pediatrician at Weill Cornell Medicine in New York in an interview to CBS Mornings, said, "This flu season is no joke. We are seeing more cases than we would expect for this time of year. We are seeing influenza A, and within influenza A we are seeing a subtype or variant called H3N2."

Scientist Jesse Bloom, at the Fred Hutchinson Cancer Center who studies viral evolution said that "it is pretty likely to be an H3N2-dominated flu season. I don't see any reason to think that this is an unprecedentedly bad one, but current indicators are that it may be substantially more severe than the typical winter flu season," as reported by CBS News.

Not just the UK, but as per the journal of the British Medical Association, even the United Kingdom is suffering from an early and severe fly season, all thanks to the influenza A H3N2 called subclade K. Neil Maniar, director of the master of public health program at Northeastern University said, "The United Kingdom got hit pretty hard by this," as well as Europe and Australia. "I think that's a pretty good harbinger of what we are likely to see here. This is going to be a very difficult flu season."

Experts are pointing out that while the vaccine may not be a good match for the updated flu virus circulating, it is still the best line of defense. Flu vaccines have an efficacy rate of 40% to 60%, however, as per as early report by Eurosurveillance, the efficacy of the current vaccine rate was between 32% to 39% in adults, and 72% to 75% in children. However, it is still important to get the vaccine to avoid any severe illness from the flu virus, point out experts.

"If you haven’t done so, get (the vaccine)," Maniar pointed out. “Definitely get it as we go into the holidays, as we go into new year’s and the new school year." It takes about two weeks to build up a solid immune response, however, within several days of getting the vaccine, people start to develop some immunity.

The Virus Is Changing

Dr Helen Chu, a flu expert at the University of Washington told the CBS News that based on the UK and Japan data, there will be more cases of hospitalization by this flu. The flu activity is "starting everywhere right now" and would be overlapping with RSV, before the winter COVID-19 wave.

Trevor Bedford, who also studies viral evolution at the Fred Hutchinson Cancer Center, said H3N2 tends to evolve faster than other influenza strains. "I expect more H3 incidence than the typical year and poorer vaccine effectiveness," he said.

"Total season effectiveness is probably going to actually be much, much lower," Chu warned, because immunity fades over time.

However, despite the mismatch in the vaccine, experts stress the fact that the flu vaccine is still helping preventing severe illness, especially in children. They also help in preventing severe diseases, hospitalization and deaths.

Barry Manilow, singer, has been diagnosed with lung cancer and will be undergoing a surgery for the same. He announced this update on his social media post on Monday. Currently 82, he said he had been fighting bronchitis for more than two months, and it was when his doctor ordered an MRI that the test "discovered a cancerous spot on my left lung that needs to be removed. It is pure luck (and a great doctor) that it was found so early."

He said that doctors do not think that the cancer had spread and that he will have additional tests to confirm the diagnosis.

“No chemo, No radiation. Just chicken soup and I Love Lucy reruns,” he wrote.

However, Manilow did not mention when he would be having the surgery, however, he is expected to rest for a month to fully recover from it. This means the nine concert dates that are scheduled for January could be postponed. “Just like you, we were all looking forward to the January shows and hate having to move everything around,” he wrote. However, no other information on the rescheduled concert dates were provided.

What Is Lung Cancer?

As per the Centers for Disease Control and Prevention (CDC), lung cancer begins in the lungs and may spread to lymph nodes or other organs in the body, including brain too, if not caught early. Cancer cells from other organs too could spread to the lungs, this process is called metastases.

In lung cancer, uncontrolled growth of abnormal cells in the lung tissues, usually in the lining of air passages, forms tumors that disrupt normal breathing and can spread to other parts of the body. This is also the leading cause of cancer death.

There are several types of cancer, and in lung cancer, there are two main types called:

• Small cell Cancer
• Non-small Cell cancers: including adenocarcinoma, squamous cell carcinoma, and large cell carcinoma

These types of cancer grow differently and are treated differently. Non-small cell lung cancer is more common than small cell lung cancer. Manilow, however, did not specify the type of lung cancer he has been diagnosed with, neither did he mention the stage of lung cancer he has been diagnosed with. However, he did note that the cancerous spots were found early on.

What Are The Common Symptoms Of Lung Cancer?

No cancer journey is the same, so people too ca have different symptoms for lung cancers. Some people may have symptoms related to lung cancer, whereas others won't feel a thing until it has spread to other parts of the body. Some people just have general symptoms of not feeling well. However, there are certain common symptoms that some people may experience, they include:

• Coughing that gets worse or doesn't go away.
• Chest pain.
• Shortness of breath.
• Wheezing.
• Coughing up blood.
• Feeling very tired all the time.
• Weight loss with no known cause.

Other changes that can sometimes occur with lung cancer may include repeated bouts of pneumonia and swollen or enlarged lymph nodes (glands) inside the chest in the area between the lungs.

If you experience any of these signs, it is best that you speak to your doctor and get your tests done.
