Global campaign on prevention of encephalitis launched
Mumbai: UK-based
Encephalitis International
on Tuesday launched a global campaign titled 'Preventing Future Encephalitis:
Climate Change
and Infectious Disease' to promote the importance of vaccination against the rising threat of encephalitis and other
vaccine-preventable diseases
.
Encephalitis is inflammation of the active tissues of the brain caused by an infection or an autoimmune response. In a release issued on Tuesday, Encephalitis International said the campaign aims to raise awareness about how climate change was exacerbating the risk of encephalitis in India and globally.
The UK-based health charity organisation said the warming planet was creating conditions favourable to the spread of infections that can lead to encephalitis. Encephalitis affects over 1.5 million people globally each year - about three people every minute. Yet, nearly 77 per cent of the population remains unaware of the condition, leading to delays in diagnosis and treatment, the release said.
"As the earth warms, new and emerging infections, including those that cause Encephalitis, will continue to rise. The vectors that can spread
infectious diseases
like mosquitoes and ticks are moving to new communities and environments," said Dr Ava Easton, Chief Executive of Encephalitis International.
Easton added that changing human and animal interactions and the movement of disease-carrying vectors like mosquitoes into new areas are compounding the risk. Outbreaks of vaccine-preventable diseases, including measles, meningitis and encephalitis, are increasing globally, whereas diseases like diphtheria, once well-controlled, are also at risk of re-emerging.
"Vaccines have saved more than 150 million lives over the past five decades," the release quoted World Health Organization (WHO)'s Director-General Dr Tedros Adhanom Ghebreyesus. "Outbreaks of vaccine-preventable diseases are increasing around the world, putting lives at risk and exposing countries to increased treatment costs," he said.
India's Universal Immunisation Programme (UIP), one of the world's largest, targets 27 million infants and 30 million pregnant women annually. It provides free vaccination against 12 diseases, including Japanese Encephalitis in endemic areas, the release said. India reported 1,548 cases of Japanese encephalitis from 24 states and union territories in 2024, underscoring the scale of the challenge.
Encephalitis International is hosting a global webinar on April 29 to explore the link between climate change and the rising burden of encephalitis, as well as strategies to boost vaccine coverage, especially in rural areas. "A vaccinated world is a safer world - each shot is a step towards freedom from preventable diseases," Dr Netravathi M, a professor at National Institute of Mental Health and Neuro Sciences (NIMHANS) Bengaluru, said, highlighting the long-term benefits of vaccination.

Is there a link between Vitamin D deficiency and heart attacks?
Recent studies explore the connection between vitamin D deficiency and heart attacks, revealing inconsistent findings. An Australian trial indicated that vitamin D supplementation might lower the risk of major cardiovascular events, particularly heart attacks and coronary revascularization. However, other research, including a Michigan State University study, found no significant reduction in cardiovascular disease risk with vitamin D supplements. Cardiovascular diseases (CVDs) are on the rise across the globe. According to the World Health Organization, CVDs are the leading cause of death globally, taking an estimated 17.9 million lives each year. Researchers are looking at the factors that contribute to CVDs, especially heart attacks, and its link with Vitamin D deficiency has been gaining popularity of late. Is there a link between vitamin D deficiency and heart attacks? Let's take a look. What is vitamin D Vitamin D, also known as the 'sunshine vitamin', is a fat-soluble nutrient essential for maintaining healthy bones, supporting immune function, and promoting overall well-being. The body produces it when exposed to sunlight, and it's also found in certain foods and supplements. People in developed nations may have insufficient levels, particularly those with limited sun exposure or darker skin tones. Link between vitamin D deficiency and heart attacks Multiple studies have identified an association between low vitamin D levels and cardiovascular issues, including sudden heart attacks. Though observational studies have consistently shown a link between vitamin D levels and CVD risk, randomised controlled trials have found no evidence that vitamin D supplements prevent cardiovascular events. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Buy Brass Idols - Handmade Brass Statues for Home & Gifting Luxeartisanship Buy Now Undo To see if there is a link, the Australian researchers conducted a Trial (2014–2020) in older adults. The 2023 study involved 21,315 participants aged 60–84, who were randomly assigned to receive either 60,000 IU of vitamin D or a placebo monthly for up to five years. The researchers also collected data on hospital admissions and deaths to identify major cardiovascular events, including heart attacks, strokes, and coronary revascularisation (treatment to restore normal blood flow to the heart). During the trial, most participants (80%) took their tablets regularly over five years. The researchers found that those who received vitamin D had a 9% lower rate of major heart-related events compared to the placebo group. The rate of heart attack was 19% lower and the rate of coronary revascularization was 11% lower in the vitamin D group, but there was no difference in the rate of stroke between the two groups. The findings suggested that vitamin D supplementation may reduce the risk of major cardiovascular events. 'This protective effect could be more marked in those taking statins or other cardiovascular drugs at baseline,' the researchers said. Representative image. Another 2021 study found that vitamin D supplementation lowered the risk of heart disease in people with dark skin. Though most of the darkly pigmented people are at greater risk of vitamin D deficiency, especially in areas with less sun exposure, supplementation drastically reduces the risk of blood vessel dysfunction, hypertension, and cardiovascular diseases. "Vitamin D supplementation is a simple and safe strategy to ensure vitamin D sufficiency. Our findings suggest that promoting adequate vitamin D status in young, otherwise healthy adults may improve nitric oxide availability and blood vessel function, and thereby serve as a prophylactic to reduce the risk of future development of hypertension or cardiovascular disease," the researcher said. Easy ways to increase your Vitamin D intake A 2019 Michigan State University study found that taking vitamin D supplements did not really reduce the risk of cardiovascular disease. The large-scale study noted that vitamin D supplements did not decrease the incidence of heart attacks, strokes, or other major adverse cardiovascular events. "We thought it would show some benefit. It didn't show even a small benefit. This was surprising," the researchers said. They also suggested thinking twice before taking vitamin D to reduce the risk of a heart attack or other cardiovascular issues. "We don't recommend taking vitamin D to reduce this risk," they said. What you should do The NIH recommends a daily intake of 600 IU of vitamin D (mostly from foods) for people ages 1-70 and 800 IU for adults ages 71 and older. While vitamin D deficiency is linked to cardiovascular diseases, going overboard with supplements is not recommended. Getting too much can lead to adverse effects, including high calcium levels in the blood or kidney stones. To get adequate vitamin D, get incidental sun exposure. Also, eat vitamin D-rich foods, including fatty fish, fortified dairy products and cereals, and certain mushrooms. Also, consult a doctor before taking any supplements.

MORE Every year on June 7th, the global community observes World Food Safety Day, a United Nations initiative aimed at raising awareness about the importance of food safety and inspiring action to prevent, detect, and manage foodborne risks. With the theme for 2025 being 'Food Safety: Prepare for the Unexpected,' this year's commemoration focuses on enhancing the resilience of food safety systems in the face of emergencies, whether caused by natural disasters, economic crises, or global pandemics. World Food Safety Day, established in 2018 by the United Nations General Assembly and led jointly by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO), underscores that food safety is everyone's business—from farm to fork. With 600 million cases of foodborne illnesses annually, the stakes are high. This article delves into the significance of World Food Safety Day, the current global challenges, and the shared responsibility in ensuring that the food we eat is safe. The Global Burden of Unsafe Food Unsafe food is a silent epidemic. According to WHO, 1 in 10 people worldwide fall ill after consuming contaminated food, and an estimated 420,000 die every year. The most vulnerable are children under five, who account for 40% of the foodborne disease burden, resulting in 125,000 deaths annually. Foodborne illnesses can be caused by bacteria, viruses, parasites, or chemical substances entering the food chain. Common culprits include Salmonella, E. coli, Listeria, and noroviruses. In low- and middle-income countries, poor infrastructure, lack of awareness, and weak regulatory systems often exacerbate the problem, turning preventable health risks into deadly threats. But food safety is not only a health issue—it is an economic and social one. Unsafe food restricts global trade, reduces productivity, and places a burden on healthcare systems. The World Bank estimates that foodborne illnesses cost low- and middle-income economies around $95 billion a year in lost productivity. Why Food Safety Matters More Than Ever In an increasingly globalized food system, ingredients and final products cross multiple borders before reaching consumers. A fruit snack made in one country might contain nuts from another, sweeteners from a third, and be packaged in a fourth. This global complexity, while economically efficient, introduces many opportunities for contamination or error. Furthermore, climate change has intensified the challenge. Rising temperatures and shifting weather patterns can promote the spread of foodborne pathogens and mycotoxins. Insects, pests, and fungal diseases are also on the rise, threatening the integrity of crops and food supply chains. The COVID-19 pandemic was another stark reminder of the vulnerability of food systems. Though not a foodborne virus, the pandemic disrupted food processing, transport, and retail systems. It highlighted the importance of emergency preparedness, supply chain traceability, and public communication during health crises—all crucial themes for this year's observance. 2025 Theme: 'Food Safety: Prepare for the Unexpected' The 2025 theme highlights the need for resilient food safety systems that can withstand unexpected challenges, including natural disasters, pandemics, cyberattacks, and supply chain disruptions. Emergencies can disrupt food production and inspection processes, compromise cold chains, and overwhelm regulatory agencies, potentially leading to significant food safety issues. Whether it's a power outage that spoils stored meat or a flood contaminating water sources used in irrigation, being prepared is key. Governments and businesses are encouraged to invest in: Risk-based inspection systems Data-sharing platforms for real-time alerts Public education campaigns Robust traceability systems Contingency planning and crisis simulations As the FAO aptly puts it: 'Safe food allows for the uptake of nutrients and promotes long-term human development.' Preparedness ensures that this fundamental right is not interrupted, even in times of crisis. The Five Keys to Safer Food The WHO promotes a set of practical principles known as the 'Five Keys to Safer Food', which are crucial for food handlers at every level—from household kitchens to commercial processors: Keep Clean: Wash hands, surfaces, and equipment frequently. Separate Raw and Cooked Foods: Prevent cross-contamination by using separate utensils and storage. Cook Thoroughly: Ensure the food reaches a safe internal temperature. Keep Food at Safe Temperatures: Avoid the 'danger zone' (4°C–60°C) where bacteria multiply rapidly. Use Safe Water and Raw Materials: Select fresh, wholesome ingredients and ensure the quality of the water used. These five principles are deceptively simple, yet their consistent application can prevent many foodborne illnesses worldwide. Food Safety Across the Supply Chain Farmers and Producers: Food safety starts at the source. Good Agricultural Practices (GAPs), pesticide management, clean water for irrigation, and animal health monitoring all contribute to the production of safe food and livestock. Processors and Manufacturers: The food industry must implement Hazard Analysis and Critical Control Point (HACCP) systems to identify potential risks and take preventative measures. Distributors and Retailers: Maintaining a cold chain, proper labeling, and ensuring hygiene in storage areas are essential for preserving food safety. Consumers: From washing produce to storing leftovers properly, individuals have a role to play. World Food Safety Day serves as a call to action for all to be informed and vigilant. Food Safety and the Sustainable Development Goals Food safety intersects directly with several Sustainable Development Goals (SDGs): SDG 2: Zero Hunger – Access to safe food is a key component of food security. SDG 3: Good Health and Well-being – Reducing foodborne illnesses contributes to better public health. SDG 12: Responsible Consumption and Production – Promotes sustainable food practices across the supply chain. SDG 17: Partnerships for the Goals – Achieving food safety requires cooperation among nations, sectors, and communities. Without safe food, no country can achieve food security or improved nutrition, essential pillars of sustainable development. Innovations in Food Safety As the world grapples with new challenges, technology is playing an increasingly pivotal role in enhancing food safety: Blockchain allows transparent tracking of food items from origin to shelf, enabling faster recalls when issues arise. Artificial Intelligence (AI) and machine learning help predict contamination patterns and optimize inspection processes. Biosensors and innovative packaging provide real-time monitoring of spoilage or bacterial presence. Drones and satellite imaging help monitor agricultural practices and ensure water safety. These innovations, while not a substitute for regulation or training, offer exciting tools to augment our food safety systems. Shared Responsibility: A Call to Action World Food Safety Day is not merely symbolic—it is a call to action for all stakeholders. Governments must enact and enforce science-based regulations. Industries must prioritize safety, transparency, and training. Academic institutions should lead research and develop safer production methods. Media must communicate risks and best practices effectively. Consumers must stay informed and take individual responsibility. As Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, once noted: 'There is no food security without food safety.' Conclusion In a world of over 8 billion people, food safety might seem like an invisible issue—until it fails. A single lapse can lead to widespread illness, economic damage, and even loss of life. But when it works, food safety quietly supports health, trade, development, and peace. World Food Safety Day serves as a reminder that vigilance, preparedness, and cooperation are essential. Whether you're a policymaker in a capital city, a farmer in a rural village, or a parent preparing dinner, your actions matter. Safe food saves lives, and it starts with each of us. Let us mark this year's World Food Safety Day by renewing our commitment to protecting the world's food supply—for today, and for generations to come.

World Brain Tumour Day 2025: Early Diagnosis And Awareness Key To Brain Health For All Ages
Every year, June 8th is observed as World Brain Tumour Day, a global initiative to raise awareness about brain tumours, their symptoms, treatment, and the importance of early detection. The theme for 2025, "Brain Health for All Ages," underscores the need for vigilant brain care across all demographics—children, adults, and the elderly alike. Dr. V. Bramha Prasad, Consultant Neuro Surgeon, Apollo Hospitals, Secunderabad shares early diagnosis and awareness key to brain health for all ages on this World Brain Tumor Day 2025. What is a Brain Tumour? A brain tumour is an abnormal mass of tissue where cells grow uncontrollably, disrupting normal brain function. Unlike healthy cells that follow the body's biological rules, tumour cells grow unchecked, compressing or invading brain structures. This growth within the rigid confines of the skull can elevate intracranial pressure, shift brain structures, or damage nerves and tissues. Tumours may remain within the central nervous system (CNS)—comprising the brain and spinal cord—and rarely spread elsewhere. Brain tumours are classified as primary (originating in the brain) or metastatic (spread from another part of the body). Primary tumours may be glial (gliomas) or nonglial (arising from brain structures like nerves and blood vessels). Metastatic tumours, which are more common, often result from cancers of the lungs, breast, or other organs. Recognizing the Symptoms Early symptoms can mimic other medical conditions, making diagnosis difficult. In adults, common signs include: Persistent headaches, worse in the morning Seizures or convulsions Nausea or vomiting Speech or cognitive difficulties Personality changes Weakness or paralysis on one side Vision disturbances and memory loss In children, symptoms may present differently and subtly, such as: Morning vomiting without nausea Balance or coordination issues Increasing head size in infants Vision problems, unexplained irritability, or drowsiness If any of these symptoms persist or worsen over time, consulting a doctor is crucial for accurate diagnosis. Malignant vs. Benign Tumours While not all brain tumours are cancerous, they can be life-threatening due to their location. Malignant tumours (e.g., glioblastomas) grow aggressively and infiltrate surrounding tissue. Benign tumours, though slower-growing, may still pose serious risks if located near critical brain structures. Brain tumours are graded using the World Health Organization (WHO) classification system, which helps predict tumour behavior and guides treatment decisions. It's worth noting that even benign tumours may evolve into malignant forms, and both types can recur after treatment. Diagnosis and Treatment Diagnosis typically involves: Neurological examinations Imaging (MRI or CT scans) Biopsy for tumour typing Treatment is often multidisciplinary, involving neurosurgeons, oncologists, and radiologists. Approaches may include: Surgery – to remove or reduce tumour size – to remove or reduce tumour size Radiation therapy – to destroy remaining tumour cells to destroy remaining tumour cells Chemotherapy – for aggressive or inoperable tumours Treatment plans vary depending on the tumour's type, location, and the patient's age and overall health. Some tumours enter remission, where they stop growing. However, recurrent tumours may develop, requiring continuous follow-up and imaging.
