Every year on May 16, India observes National Dengue Day. This day raises awareness about the growing threat of dengue fever, especially during the monsoon season. Usually, it is during the monsoon that due to stagnant water, mosquito breeding increases. The government also aims to highlight the importance of prevention, public participation for awareness, as well as timely medical care to control the spread of the disease.

National Dengue Day 2025 Theme:

Each year, a unique theme is observed in order to raise awareness. This year, the main theme is people-led prevention. The theme is : Act Early, Prevent Dengue: Clean Surroundings, Healthy Living.

Origin of National Dengue Day

The Ministry of Health designated May 16 as National Dengue Day in 2010. This was done to intervene when dengue cases increased throughout the pre-monsoon and monsoon seasons.

As per the World Health Organization (WHO), "Dengue epidemics tend to have seasonal patterns, with transmission often peaking during and after rainy seasons. There are several factors contributing to this increase, and they include high mosquito population levels, susceptibility to circulating serotypes, favourable air temperatures, precipitation and humidity, all of which affect the reproduction and feeding patterns of mosquito populations, as well as the dengue virus incubation period. Lack of proactive control interventions and staff are some of the other challenges."

Dengue And India: Significance

Due to climate change, monsoon has arrived early, thus the Union Health Ministry has directed all air, sea, and land ports across the country to step up surveillance for vector-borne diseases. Authorities have been asked to strengthen preventive and control measures to curb the spread of infections such as dengue, chikungunya, Zika, and yellow fever.

The advisory comes amid concerns over rising cases during the rainy season, a period that typically sees a surge in mosquito breeding and transmission. India continues to report a significant number of cases and deaths linked to vector-borne illnesses each year, making early intervention and preparedness critical.

Dengue and India: History

As per a 2012 study published in the Indian Journal of Medical Research, the official journal of the Indian Council of Medical Research, titled Dengue in India, notes that it was in 1780 when the first epidemic of clinical dengue-like illness was recorded in Madras (now Chennai). The first virologically proved epidemic of dengue fever occurred in Calcutta (now Kolkata) and the Eastern Coast of India in 1963-64.

However, during the last 50 years, notes the study, a large number of physicians have treated and described dengue diseases in India, but the scientific studies which address problems with regard to the disease may have been limited.

What is Dengue?

The study notes that Dengue is an acute viral infection with potential fatal complications. It was first referred to as "water poison" associated with flying insects in a Chinese medical encyclopedia in 992 from the Jin Dynasty.

The word "dengue" is derived from the Swahili phrase Ka-dinga pepo, which means "cramp-like seizure". The first clinically recognized dengue epidemics occurred simultaneously in Asia, Africa, and North America in the 1780s.

As per Global Medicine, the first clinical case report dates from 1789 of 1780 epidemic in Philadelphia is by Benjamin Rush, who coined the term “break bone fever” because of the symptoms of myalgia and arthralgia.

How Does Dengue Happen?

As per the Centers for Disease Control and Prevention (CDC), dengue viruses usually spread to people through the bites of infected Aedes species mosquitoes. This mosquito bites a person infected with the dengue virus and then becomes infected. The infected mosquito then bites people and infects them with the dengue virus.

Every year on September 8, World Physiotherapy Day, a global healthcare event is observed. The practice started in 1996, commemorating the date of the World Physiotherapy foundation in 1951. After major surgeries, patients are recommended physiotherapy to help them with movements, this is why a separate day is designated for a therapy that gets the patients back on their feet, doing things like they did before.

The aim of physiotherapy is to achieve a symptom-free movement at basic to complex physical activities.

The Significance of World Physiotherapy Day

Everyone values the ability to live as independently as possible in their daily lives. When injuries, illnesses, or health conditions affect movement, many people, from patients to fitness enthusiasts, turn to physical therapy. The goal is simple: to regain the ability to perform the activities that matter most to them.

Among the many approaches used in healthcare, therapeutic exercise stands out as a core component. It plays a central role in programs designed to restore function, enhance performance, and even prevent future problems.

Physical function is multidimensional, involving several interconnected areas. A well-designed therapeutic exercise plan may focus on:

• Improving balance
• Building cardiopulmonary endurance
• Developing coordination
• Increasing flexibility
• Enhancing mobility
• Strengthening muscle performance
• Boosting neuromuscular control
• Supporting postural control and stability
• Maintaining overall equilibrium

Together, these elements work to help individuals move better, feel stronger, and live more confidently.

Here Is The History Of World Physiotherapy Day

World Physiotherapy Day is observed every year on September 8, a date chosen in 1996 by the global organization World Physiotherapy. The organization itself was founded on September 8, 1951, in the United Kingdom and today represents over 600,000 physiotherapists worldwide, bringing together 127 member organizations.

World Physiotherapy works to promote safe working conditions for physiotherapists and advocates for evidence-based practices that make quality physiotherapy care accessible and affordable for all.

India has been part of this global community since 1967, with various Indian physiotherapy associations and professionals actively represented in World Physiotherapy.

The American Heart Association (AHA) and the American College of Cardiology (ACC) have just released their first major update to blood pressure management guidelines since 2017. These new recommendations go beyond simply telling you what numbers to aim for, they focus on prevention, early intervention, and more personalized care across your entire lifespan.

High blood pressure (hypertension) is one of the biggest risk factors for heart disease, the world’s leading cause of death, as well as kidney disease, stroke, type 2 diabetes, and even dementia. With nearly half of all U.S. adults having higher-than-normal blood pressure, these new guidelines are significant for millions of people.

Blood Pressure Targets Remain the Same

One thing that hasn’t changed in 8 years, is how high blood pressure is defined. The cutoff points are still the same as they were in 2017:

• Normal: Less than 120/80 mm Hg
• Elevated: 120–129 mm Hg systolic and under 80 mm Hg diastolic
• Stage 1 Hypertension: 130–139 mm Hg systolic or 80–89 mm Hg diastolic
• Stage 2 Hypertension: 140 mm Hg or higher systolic, or 90 mm Hg or higher diastolic

Your blood pressure reading has two numbers:

The top number (systolic) measures the pressure when your heart pumps, while the bottom number (diastolic) measures it when your heart is at rest.

More Aggressive Early Intervention

While the numbers haven’t changed, how doctors treat them has. The new guidelines recommend starting with healthy lifestyle changes, like eating better, exercising, and reducing salt, for anyone with readings in the 130–139 range. If those changes don’t work after three to six months, medication may be prescribed earlier than before.

This shift is meant to prevent complications before they start. “We’re aiming to help more people get their blood pressure under control earlier to prevent heart disease, strokes, kidney problems, and even dementia,” said Dr. Daniel W. Jones, chair of the writing committee for the new guidelines.

A Bigger Focus on Weight Loss and GLP-1 Medications

One of the most notable updates involves the use of GLP-1 receptor agonists, such as Ozempic and Mounjaro, which have become popular for weight loss. The guidelines now say that patients who have high blood pressure and are overweight should discuss these medications with their healthcare provider, as losing weight can dramatically improve blood pressure control.

For people with severe obesity, surgery may even be recommended if lifestyle changes and medications are not enough.

New Pregnancy and Postpartum Recommendations

High blood pressure during pregnancy can be dangerous, leading to complications such as preeclampsia, which can threaten both the parent and baby. The new guidelines recommend that pregnant and postpartum individuals with stage 2 hypertension start on certain medications to lower the risk of complications. This is an important shift, as research shows pregnancy-related hypertension can have lasting effects on cardiovascular health.

The Brain Connection: Dementia Risk

Another significant addition to the 2025 guidelines is the acknowledgment of the link between high blood pressure and cognitive decline. New research shows that hypertension can reduce blood flow to the brain, leading to memory issues and an increased risk of dementia. By controlling blood pressure early, the hope is to preserve cognitive function later in life.

The PREVENT Risk Calculator

Doctors are now encouraged to use a new tool, called PREVENT, to estimate a patient’s risk of developing heart disease over the next 10 and 30 years. This calculator considers multiple factors: age, sex, cholesterol levels, blood pressure, and more, to create a personalized risk profile and guide treatment decisions.

Alcohol Guidance Tightened

In a change that may surprise many, the updated guidelines now recommend avoiding alcohol entirely if possible. Previous advice allowed for one drink per day for women and two for men, but growing evidence shows even moderate alcohol intake can raise blood pressure. For those who still choose to drink, the AHA now advises staying under those older limits.

Lifestyle Changes Are Still the Foundation

Despite all the new tools and treatments, the cornerstone of blood pressure management remains the same: a healthy lifestyle. The updated recommendations reinforce:

• Following a heart-healthy diet like the DASH plan, rich in fruits, vegetables, whole grains, lean proteins, beans, and nuts
• Reducing sodium intake to less than 2,300 mg per day, ideally aiming for 1,500 mg
• Exercising regularly, with at least 150 minutes of moderate activity weekly plus resistance training
• Managing stress through mindfulness, yoga, or relaxation techniques
• Maintaining a healthy weight, losing at least 5% of body weight if overweight

Why This Matters

High blood pressure is often called the “silent killer” because it has no symptoms but can do significant damage over time. By encouraging earlier treatment, recognizing new links to conditions like dementia, and providing tools like the PREVENT calculator, the 2025 guidelines aim to help people live longer, healthier lives.

“The reality is that the first line of treatment, lifestyle changes, really does work if you commit to it,” Dr. Jones said. “It can be hard in today’s food environment, but the payoff is worth it.”

Russian scientists have unveiled a breakthrough that could transform colon cancer prevention and treatment worldwide. The Federal Medical and Biological Agency (FMBA) announced that its researchers have developed a vaccine targeting colorectal cancer, one of the most common and deadly cancers globally. The vaccine, named Enteromix, is based on mRNA technology, the same method used successfully in COVID-19 vaccines, and is now ready for clinical use.

FMBA head Veronika Skvortsova revealed the development at the 10th Eastern Economic Forum in Vladivostok, which brought together more than 8,400 participants from over 75 countries. According to Skvortsova, the vaccine has undergone years of research, including three years of preclinical trials, and is showing promising results.

How The Colon Cancer Vaccine Works

Enteromix uses genetic instructions to teach the body’s immune system to recognize and destroy cancer cells before they form dangerous tumors. Scientists compare it to handing the immune system a “wanted poster” of colorectal cancer cells. If such cells ever appear, the immune system attacks them immediately, preventing the tumor from growing.

This approach was tested in lab mice bred to develop colon cancer, where the vaccine achieved a remarkable 100% success rate in preventing tumor formation. Early human trials have also been completed, with volunteers tolerating the vaccine well and no serious side effects reported.

Promising Results from Preclinical Trials

The preclinical trials revealed more than just prevention. In some test subjects, existing tumors shrank or slowed their growth by 60% to 80%, depending on the cancer type. Researchers also noted improved survival rates, sparking hope that Enteromix could be used both preventively and therapeutically in the future.

Work is already underway to develop similar vaccines for other forms of cancer, including glioblastoma (a highly aggressive brain cancer) and certain types of melanoma, including ocular melanoma, which affects the eye.

Why This Matters Globally

Colorectal cancer is the third most common cancer worldwide, with rising incidence rates in many developing nations. In countries like Rwanda, cases have risen by more than 70% in the past decade, often affecting young patients who are diagnosed at late stages due to the lack of national screening programs. Late diagnosis makes treatment more difficult and survival rates much lower.

For regions with limited access to screening and treatment facilities, a preventive vaccine could be a public health game-changer. It could help bridge health equity gaps and save countless lives by offering a way to protect vulnerable populations before cancer takes hold.

What Lies Ahead?

Despite the excitement, scientists are cautious. History has shown that promising animal results do not always translate perfectly to humans. Large-scale Phase III clinical trials will be crucial to confirm Enteromix’s effectiveness and safety in diverse populations.

Still, Russia has announced plans to roll out the vaccine in the coming weeks, free of charge, marking an important milestone in global cancer research. If successful, Enteromix could offer hope to millions and usher in a new era where certain cancers can be prevented much like infectious diseases.
