Smokers who make the decision to quit will experience immediate health benefits, including a rapid reduction in their risk of atrial fibrillation (A-Fib), according to new research published in JACC: Clinical Electrophysiology. The study, conducted by Dr. Gregory Marcus, a cardiologist at the University of California, San Francisco, offers compelling evidence for smokers to quit, showing that it’s never too late to avoid the damaging effects of smoking on heart health.

Dr. Marcus, the senior author of the study, emphasized that A-Fib can be prevented even in individuals who have smoked for years. "The findings provide a compelling new reason to show current smokers that it’s not too late to quit, and that having smoked in the past doesn’t mean you’re ‘destined’ to develop A-Fib," Marcus explained. "Even for the current and longtime smoker, A-Fib can still be avoided."

What is Atrial Fibrillation (A-Fib)?

"There’s strong evidence that smoking increases the risk of A-Fib," Marcus said. "But the benefits of quitting smoking have been less certain." With this in mind, his team sought to determine whether quitting could significantly lower a person’s risk of developing A-Fib, or if the risk would remain the same.

The research team analyzed data from over 146,700 current and former smokers, tracking their smoking habits and health over a 12-year period using data from the UK Biobank database. The results were promising: former smokers had a 13% lower risk of developing A-Fib compared to current smokers, while those who quit during the study saw an 18% reduction in their risk.

"This is likely a testament to the potency of reducing atrial fibrillation risk pretty shortly after quitting," Marcus said in a statement from the American College of Cardiology.

The findings highlight the importance of quitting smoking, not only for general health but specifically for reducing the risk of serious heart conditions like A-Fib.

Tips for Quitting Smoking

Quitting smoking is one of the most effective ways to lower the risk of A-Fib and improve overall heart health. While it can be challenging, the benefits of quitting are clear and immediate. Here are some tips to help you quit smoking successfully:

1. Choose a specific date to quit smoking and stick to it. Prepare yourself mentally and physically for this change.

2. Reach out to family, friends, or a support group to help keep you accountable. Sharing your goals with others can provide encouragement.

3. Options like nicotine patches, gum, or lozenges can help ease withdrawal symptoms and reduce cravings.

4. Identify situations that make you want to smoke, such as stress or social gatherings, and find healthy ways to cope with them.

5. Regular exercise can help distract you from cravings and improve your mood during the quitting process.

6. Drinking water can help flush nicotine out of your system faster, reducing cravings.

7. Activities like yoga, meditation, or deep breathing exercises can help manage stress, a common trigger for smoking.

Quitting smoking offers immediate and significant benefits, particularly in reducing the risk of atrial fibrillation. The latest research provides smokers with more motivation to quit, showing that it's never too late to take control of their heart health.

The United States has issued a travel advisory against global polio. International travel often comes with vaccine reminder and health checks to stay safe. The Centers for Disease Control and Prevention (CDC) issued a Level 2 travel advisory for certain international destinations with circulating poliovirus. The CDC has asked travellers to ensure they are up to date on their polio vaccines.

The Destination list for global polio travel notice includes:

• Afghanistan
• Algeria
• Angola
• Benin
• Burkina Faso
• Cameroon
• Central African Republic
• Chad
• Côte d'Ivoire (Ivory Coast)
• Democratic Republic of the Congo
• Djibouti
• Ethiopia

• Tanzania, including Zanzibar
• United Kingdom, including England, Scotland, Wales, and Northern Ireland
• Yemen
• Zimbabwe

The CDC issued a 'Level 2' advisory, which means to 'practice enhanced precautions'.

The advisory suggests that children and adults should be up to date on their routine polio vaccines. Travelers are also asked to get an inactivated polio vaccine booster if they are going to the destination that has circulating poliovirus, or have completed their routine polio vaccine series; and have not already received one adult booster dose.

Types Of Notices Issued By CDC

The CDC issues four different types of notices based on the gravity of the disease spread.

Level 1 : Practice Usual Precautions

Practice usual precautions for this destination, as described in the Travel Health Notice and/or on the destination page.

Level 2: Practice Enhanced Precautions

Practice enhanced precautions for this destination. The Travel Health Notice describes additional precautions or defines a specific population at risk.

Level 3: Reconsider Nonessential Travel

Reconsider nonessential travel to this destination. The outbreak or event poses risk to travelers because limited precautions are available.

Level 4: Avoid All Travel

Avoid travel to this destination unless traveling for humanitarian aid or emergency response; there is an extreme health risk for travelers and no available precautions.

What Is Polio?

The World Health Organization (WHO) notes that it is a highly infectious disease caused by a virus that invades the nervous system and can cause total paralysis in matter of hours. The virus is transmitted by person to person spread mainly through the fecal-oral route, or less frequently, by a common vehicle, which could be either from contaminated food or water. The virus also multiplies in the intestine.

The National Institute of Health (NIH), US, notes that the virus responsible for causing Polio belongs to the Picornaviridae family.

As per the WHO, the common Polio symptoms are:

• Fever
• Fatigue
• Headache
• Vomiting
• Stiffness of the neck a
• Pain in the limbs

How Does Polio Spread?

Polio is mainly transmitted through the faecal-oral route, meaning it spreads when a person consumes food or water contaminated with the virus. It can also spread through close contact with an infected individual. The poliovirus lives in the throat and intestines of those infected, and poor sanitation, unsafe water, and inadequate hygiene greatly increase the risk of transmission, especially in communities with limited access to clean facilities.

In severe cases, polio can lead to acute flaccid paralysis, which may affect the diaphragm and throat muscles, making it difficult to breathe or swallow. Since there is no cure for polio, prevention remains the only line of defence. Raising awareness about polio vaccination is therefore essential to protect individuals, especially children, from this potentially life-threatening disease.

500 girls have received the Human papillomavirus (HPV) vaccines in the first five days of launching the cervical cancer prevention drive. A senior officer, as also reported by TOI noted that misinformation and lack of awareness could lead to a lower number of girls showing up. This is why, while the initial response is encouraging, logistics are still need to be figured out, including identification of session sites and to widen coverage and counter doubts that surround the vaccine. "The HPV vaccine helps prevent cervical caner, one of the most common cancers among women in the country. Addressing public concerns is crucial for the program's success," said the official.

Health officials along with public health experts will be conducting interactive sessions on social media across districts on Thursday. In Sikar, a dedicated platform will also allow experts to respond to the questions directly on HPV infections, vaccine safety, eligibility and benefits.

As of now, the program allows a single vaccine dose for girls who have completed 14 years and are yet to turn 15. As per the Health Department, around 8.32 lakh girls in Rajasthan are eligible for the vaccine annually.

Nationwide Free HPV Vaccine Drive

Prime Minister Narendra Modi on February 28 launched the nationwide Human Papillomavirus (HPV) vaccination campaign for girls aged 14 years from Rajasthan's Ajmer.

The initiative marks a decisive step towards eliminating cervical cancer through timely HPV vaccination. Cervical cancer remains the second most common cancer among women in India. Nearly 80,000 new cases and over 42,000 deaths are reported annually in the country.

"Today, I have had the opportunity to launch the HPV vaccine campaign from Ajmer. This campaign is an important step towards empowering women and daughters of this country,” PM Modi said.

“For us, this was a sensitive issue tied to the insult of our sisters and daughters, one that made them ill. That is why we resolved it at a crucial turning point in their mission,” he added.

The World Health Organization has also lauded India's mission to launch the HPV vaccine and prevent the risk of cervical cancer.

“We are leaving no stone unturned to ensure that the daughters of the country are healthy and prosperous. The objective of this initiative is the prevention of cervical cancer," the Prime Minister, earlier wrote in a post on social media platform X.

Who Can Avail The Nationwide Free HPV Vaccination Drive?

The vaccine is most effective when it is administered before exposure to HPV and before becoming sexually active. Young women aged 9 to 14 years show vaccine effectiveness of 74 to 93 per cent and this decreases with age.

Adults aged 27 to 45 must get it after consultation with their healthcare provider

Chile became the first country in the Americas to be verified by the World Health Organization (WHO) for the elimination of leprosy. WHO with Pan American Health Organization (PAHO), congratulated Chile for becoming the first country in the Americas and second globally to eliminate leprosy.

Leprosy (Hansen disease) was historically recorded in Chile at the end of the 19th century on Rapa Nui (Easter Island). The disease was limited in mainland Chile, with sporadic introductions, contained through isolation and treatment measures in the Island, where the last secondary cases were managed by the late 1990s.

Since then, Chile did not report locally acquired case of leprosy in more than 30 years. The last locally acquired case was detected in 1993. However, the disease was never removed from public health agenda and remained a notifiable condition and monitored through mandatory reporting, surveillance and continuous clinical readiness.

Chile Makes History In Health Care

Dr Tedros Adhanom Ghebreyesus, WHO Director-General said, “This landmark public health achievement is a powerful testament to what leadership, science, and solidarity can accomplish. Chile’s elimination of leprosy sends a clear message to the world: with sustained commitment, inclusive health services, integrated public health strategies, early detection and universal access to care, we can consign ancient diseases to history.”

PAHO Director Dr Jarbas Barbosa said, "Chile’s achievement demonstrates that eliminating leprosy is achievable and requires building strong systems that can detect, respond to, and provide comprehensive care for people affected by the disease, including those living with chronic disabilities. Being the first country in the Americas to be confirmed as eliminating leprosy sends a powerful message to the Region – that diseases strongly linked to groups living in vulnerable conditions can be eliminated, contributing to interrupt the vicious circle between disease and poverty.”

How Did Chile Achieve Elimination of Leprosy?

As per WHO between 2012 and 2023, Chile reported 47 cases nationwide, none of which were locally acquired.

WHO notes that Chile's integrated model ensures early detection and comprehensive care: primary care centers serve as the entry point for suspected cases, with timely referrals to specialized dermatology services for diagnosis, treatment, and follow-up. Clinicians receive training aligned with WHO's Towards zero leprosy strategy. The system prioritizes early intervention, disability prevention, and holistic care, including physiotherapy and rehabilitation services, ensuring that anyone affected by leprosy receives continuous support for both acute and long-term health needs to promote full recovery and social inclusion.

What Is Leprosy?

Leprosy is also known as Hansen disease. It is a chronic infectious disease that is caused by bacterium Mycobacterium leprae. It affects the skin, peripheral nerves, upper respiratory tract mucosa and eyes.

If it is not treated timely, it could lead to permanent nerve damage, disabilities and social stigma. However, the condition is fully curable with multidrug therapy and early detection could prevent further complications.
