Covid cases increase in Asia: What is causing the spike and what should we do? Doctors explain new symptoms
Testing is very crucial to identify which particular strain is the prominent one causing the outbreak. And so that data then needs to be shared between the countries and within the country between different states.
India and parts of Asia are witnessing a noticeable surge in COVID-19 cases. Health experts link this increase primarily to the emergence of new subvariants of the Omicron strain, particularly the JN.1 lineage.
What’s Causing the Spike?
Dr. Manisha Mendiratta, Associate Director & Head – Pulmonology, Sarvodaya Hospital, Faridabad, outlines several contributing factors:
1. Highly Transmissible Omicron Subvariant – JN.1
-
The JN.1 variant is highly infectious and exhibits greater ability to evade immunity.
-
Though not more lethal, it spreads rapidly, especially in populations with declining immunity.
-
Symptoms tend to remain mild in vaccinated individuals.
2. Waning Immunity
-
Many people in Asia received vaccines over a year ago.
-
With low booster dose uptake, immunity has decreased over time.
-
Vulnerable groups like the elderly and those with underlying health conditions are at increased risk.
3. Relaxation of COVID Protocols
-
Mask-wearing, social distancing, and hygiene practices have significantly declined.
-
Resumption of large public gatherings and international travel has increased opportunities for viral spread.
4. Seasonal and Environmental Factors
-
Cooler weather is driving people indoors, where poor ventilation increases transmission risk.
-
Underreporting due to reduced testing may mean the actual case count is much higher than reported.
Symptoms Associated with the JN.1 Variant
-
Headache
-
Sore throat
-
Fever
-
Dry cough
-
Diarrhoea (more frequently observed with JN.1)
-
Runny or blocked nose
-
Fatigue or exhaustion
-
Loss of taste or smell
What Should India Do?
Dr. Sandeep Budhiraja, Senior Director, Institute of Internal Medicine & Group Medical Director, Max Healthcare, advises the following:
-
Remain vigilant and monitor incoming international travelers.
-
Track the rise in flu-like illnesses to catch any unusual surges.
-
Genomic surveillance testing is crucial, especially for symptomatic or at-risk individuals.
-
Isolation is necessary when symptoms or positive tests arise.
“If the cases increase, we must reconsider our vaccination strategy, especially for high-risk groups such as the elderly, immunocompromised individuals, and those with chronic health conditions,” Dr. Budhiraja emphasized.
Preventive Measures Remain Crucial
Both experts reinforce the importance of continuing preventive practices:
-
Regular hand washing
-
Wearing masks in crowded places
-
Social distancing
-
Staying home if infected
“There is absolutely no need to panic. But we must stay alert in the coming weeks to assess how this outbreak progresses, especially across parts of Asia,” Dr. Budhiraja added.

Could Poor Digestion Be Causing Your Body Pain? Ayurveda Expert Explains
Chronic pain rarely appears suddenly—it develops over time, often signaling deeper imbalances within the body. While many people rely on temporary relief like painkillers, recurring discomfort may point to underlying issues that go beyond muscles and joints.
According to Dr. Partap Chauhan, a renowned Ayurveda expert with over four decades of experience, two of the most overlooked causes of chronic pain are poor digestion and unhealthy lifestyle patterns.
The Ayurvedic Perspective: Body as One System
In Ayurveda, the body is viewed as an interconnected system where physical, mental, and lifestyle factors are deeply linked.
“The body does not function in isolation. What you eat, how you live, and how your system processes everything are all connected,” explains Dr. Chauhan.
When this internal balance is disrupted, the body’s ability to heal and recover slows down—often leading to persistent discomfort.
How Digestion Influences Pain
A key concept in Ayurveda is Agni (digestive fire), which governs how efficiently the body processes food and absorbs nutrients.
When digestion is strong:
- Nutrients are properly absorbed
- Waste is efficiently eliminated
- The body maintains balance
However, when digestion weakens, it leads to the formation of Ama (toxins).
“These toxins don’t remain confined to the digestive system. They circulate through the body and accumulate in vulnerable areas like joints or muscles,” says Dr. Chauhan.
Over time, this can result in:
- Inflammation
- Stiffness
- Recurring or chronic pain
“What the body cannot process, it begins to carry—and that burden often manifests as pain,” he adds.
Lifestyle Habits That Worsen the Problem
Beyond digestion, daily habits play a crucial role in maintaining health.
Irregular routines such as:
- Skipping meals or eating at inconsistent times
- Lack of physical activity
- Poor posture
- Inadequate or irregular sleep
can disrupt the body’s natural rhythm.
“When routines are inconsistent, digestion and circulation are affected, which in turn impacts the body’s ability to recover,” Dr. Chauhan explains.
The Role of Routine (Dinacharya)
Ayurveda emphasises dinacharya—a structured daily routine—to restore balance and improve overall well-being.
Simple, sustainable habits can make a big difference:
- Eating meals at fixed times
- Staying physically active
- Maintaining proper sleep cycles
- Practicing mindful living
“It’s not about intensity but consistency,” says Dr. Chauhan. “Small changes, when practiced daily, can have a lasting impact.”
Beyond Quick Fixes: A Long-Term Approach
Unlike conventional approaches that often focus on symptom relief, Ayurveda aims to address the root cause.
“When digestion improves and lifestyle aligns with natural rhythms, the body gradually regains its ability to heal,” Dr. Chauhan notes.
This process may take time, but it offers more sustainable results.
Additional Insights: Early Warning Signs
According to Ayurvedic principles, some early signs of poor digestion that may eventually lead to pain include:
- Bloating or heaviness after meals
- Frequent fatigue
- Irregular bowel movements
- Brain fog or low energy
Recognising these signals early can help prevent long-term complications.
Key Takeaway
Chronic pain is not always just a physical issue—it can be a reflection of deeper imbalances in digestion and lifestyle. By focusing on internal health and consistency in daily habits, long-term relief becomes possible.

From Smallpox to Polio: Diseases Gen Z Has Rarely Seen, Thanks to Vaccines
During World Immunization Week (April 24–30), the spotlight turns to one of the most powerful tools in modern medicine—vaccination.
Not long ago, infectious diseases shaped entire generations. They caused widespread deaths, lifelong disabilities, and global fear. Today, however, many people from Gen Z have never encountered these illnesses firsthand—not because they vanished naturally, but because vaccines have dramatically reduced or eliminated them.
Over the past century, immunisation programmes have transformed global public health, saving millions of lives and redefining what “normal” health looks like.
🌍 How Vaccines Changed the World
Vaccines work by training the immune system to recognise and fight infections before they become dangerous. Thanks to widespread immunisation:
- Some diseases have been eradicated completely
- Others are close to elimination
- Many are now rare or controlled in most countries
This progress highlights why continued vaccination efforts remain critical.
🦠 8 Diseases Gen Z Has Largely Been Shielded From
1. Smallpox
Smallpox was once among the deadliest diseases in human history, killing millions over centuries.
- First vaccine developed in 1796
- Officially eradicated in 1980
It remains the only human disease ever completely eradicated through vaccination.
2. Polio
Polio once paralysed thousands of children every year.
- First effective vaccine introduced in 1955
- Now nearly eradicated globally
Today, cases are limited to a few regions, thanks to sustained vaccination campaigns.
3. Measles
Measles used to cause frequent outbreaks, especially among children.
- Vaccine introduced in 1963
- Cases have dropped dramatically worldwide
However, outbreaks can still occur where vaccination rates decline.
4. Mumps
Mumps caused fever, swelling, and potential complications.
- Vaccine introduced in 1967
- Later included in the MMR vaccine (1971)
Now largely controlled in vaccinated populations.
5. Rubella (German Measles)
Rubella posed serious risks during pregnancy.
- Vaccine introduced in 1969
- Prevents miscarriages and birth defects
Widespread vaccination has significantly reduced congenital rubella syndrome.
6. Hepatitis B
Hepatitis B can lead to chronic liver disease and cancer.
- Vaccine introduced in 1981
- Now part of routine immunisation in many countries
It has greatly reduced transmission, especially from mother to child.
7. Haemophilus influenzae type b (Hib)
Haemophilus influenzae type b once caused severe illnesses like meningitis in children.
- Vaccine introduced in the late 1980s
- Cases dropped sharply after immunisation
It is now rare in countries with strong vaccination programmes.
8. Tetanus
Tetanus is caused by bacteria found in soil and wounds.
- Preventable through routine vaccination
- Now rare in many parts of the world
Unlike others, it hasn’t been eradicated, but is effectively controlled.
⚠️ Why Vaccination Still Matters
Even though these diseases are rare today, they haven’t disappeared entirely. Lower vaccination rates can lead to:
- Disease outbreaks
- Increased health risks for children
- Re-emergence of controlled infections
That’s why initiatives like World Immunization Week continue to raise awareness about the importance of vaccines.
🧠 Final Take
The fact that Gen Z has grown up largely without witnessing diseases like Smallpox or Polio is not accidental—it’s the result of decades of scientific progress and global cooperation.
Vaccines haven’t just saved lives—they’ve reshaped entire generations. The challenge now is to maintain that progress by ensuring immunisation reaches everyone, everywhere.

😴 Why You Feel Tired Around 2 PM Every Day: Expert Explains the Science Behind the Afternoon Crash
That sudden drop in energy around 2 PM is something most people experience. One moment you’re productive, and the next you’re struggling to stay focused, fighting drowsiness, and reaching for caffeine.
But according to experts, this “afternoon crash” is not random—and it’s not just about workload.
🧠 It’s Not Laziness, It’s Biology
Jaipur-based endocrinologist Dr Hetashvi Gondaliya explains that afternoon fatigue is usually driven by body processes rather than mental effort.
At the core of this issue is how the body regulates energy after meals.
🍽️ Blood Sugar Fluctuations: The Biggest Trigger
One of the main reasons for the 2 PM crash is blood sugar imbalance.
When you eat meals high in:
- Refined carbs
- Sugary foods
- Processed ingredients
Your blood sugar rises quickly and then drops sharply afterward.
This “spike and crash” cycle leads to:
- Sleepiness
- Low concentration
- Mental fog
- Reduced motivation
Many people mistake this for laziness, but it is actually a metabolic response.
🕰️ Your Body Has a Natural Energy Dip
Even without food-related factors, your body follows a natural internal clock known as the circadian rhythm.
In the early afternoon:
- Alertness naturally decreases
- Body temperature slightly dips
- Reaction time slows
If combined with poor sleep or heavy meals, this dip becomes much more noticeable.
😴 Sleep Debt Makes It Worse
Even mild sleep deprivation can significantly intensify afternoon fatigue.
If you:
- Sleep late
- Wake up frequently at night
- Don’t get enough deep sleep
Your body cannot recover fully, making the 2 PM slump more severe.
🪑 Sitting After Lunch Slows You Down
Post-meal habits also play a big role.
Long periods of sitting after eating can:
- Slow digestion
- Reduce blood circulation
- Increase feelings of sluggishness
Even mild dehydration can add to fatigue, making the crash feel worse than it actually is.
💡 How to Beat the 2 PM Energy Crash
Experts recommend simple, sustainable lifestyle adjustments:
🍲 Eat smarter lunches
- Include protein (dal, eggs, paneer, chicken)
- Add fibre (vegetables, whole grains)
- Include healthy fats (nuts, seeds, olive oil)
- Avoid heavy refined-carb meals
🚶 Move after eating
- Take a 10–15 minute walk post-lunch
- Helps digestion and improves alertness
💧 Stay hydrated
- Drink water consistently throughout the day
- Avoid long gaps without fluids
😴 Fix sleep routine
- Maintain consistent sleep timing
- Aim for quality sleep, not just quantity
🧬 The Real Truth About the 2 PM Crash
The afternoon energy dip is not a flaw in your productivity—it’s a predictable biological rhythm influenced by food, sleep, hydration, and movement.
Once these factors are balanced, energy levels become significantly more stable throughout the day.
🔍 Final Take
The 2 PM crash is common, but not unavoidable. It’s your body’s way of signaling imbalance—not failure.
With small daily changes in diet, sleep, and movement, you can reduce fatigue and maintain steady focus throughout the afternoon.
