MicroRNA That Makes Them Fight COVID Better ?

Recently you may have read a New Delhi based International Center for Genetic Engineering and Biotechnology (ICGEB) sequenced the genome (genetic data) of SARS-COV-2 (coronavirus) from India, Italy, US, Nepal and Wuhan, China. They found that the Indian variant of SARS-CoV2 has the potential to be targeted by antiviral RNA within host cells, a feature that is unique to the Indian strain.

This amazing finding has been published on blogs, newspapers and other media as proof that Indians may not suffer as much as the rest of the world when the COVID-19 pandemic hits the country. One headline touted “MicroRNA in Indians may reduce severity of corona attack”, stating “Indians have comparatively better immunity compared to other countries”. Of course this article is being forwarded on WhatsApp, and enough people may take it as gospel. Is it true?

No.

If you want to know why, just look on the Journal’s website:

“these are preliminary reports that have not been peer-reviewed. They should NOT be regarded as conclusive, guide clinical practice/health-related behaviour, or be reported in news media as established information.”

Research is not easy. I could write a very long explanation for why, but I have summarised it below.

SUMMARY:

- To prove x causes y up to a high scientific standard is incredibly difficult

- Even if you think x causes y, someone might find a flaw in your study

- Numbers can be manipulated by statistics to show what you want to believe

- Reporters might not understand the study and mis-report it

- We all want to believe there is a magic cure that will protect us, that makes us special, immune to this disaster so we can get on with our lives. Unfortunately there simply isn’t one. And believing in them without fact checking can cause more harm than good.

IMMUNITY AGAINST COVID

So what about this study? Firstly it is looking at one tiny mechanism in a cell, when a cell can have millions of proteins responsible for a billion different functions in just the cell itself. Secondly it is not peer reviewed. This means no one has fact checked the study to check whether the design is valid, whether the statistics hold up, whether they have missed something or are making incorrect conclusions based off their data. Peer-reviewing a recent paper showing SARS-CoV-2 and HIV were extremely similar disproved this paper as false.

In the authors defence he acknowledges this:

“In our study, which is a purely computational one, we predicted that this microRNA binds to the SARS-Cov2 genome submitted from India. However, it is too early to comment on it because there is only one high coverage sequence from India, so far,”

Thirdly, the news article says that Indians have better immunity because of this “microRNA”. This is wrong. The study sequenced the genome of the virus, not of the Indian population. Antiviral microRNA is found in all people. The study simply suggests that this might be more effective at targeting the Indian strain of COVID, but it does not make any concrete claims that Indians are protected from COVID.

Again, the journal even states this:

“These are preliminary reports that have not been peer-reviewed. They should not be regarded as conclusive, guide clinical practice/health-related behavior, or be reported in news media as established information.”

But most importantly, even if the paper suggests that the Indian strain may be less potent, it does not give us an excuse to be reckless. We have to adhere to social distancing, hygiene, lockdown principles in order to prevent infection. Because what happens if you take the article stating “Indians have comparatively better immunity compared to other countries” as fact, use this as an excuse to go about your regular daily lives, and it actually turns out that the microRNA has little to no effect on COVID. This endangers yourself and those around you.

Be sensible. Listen to public health officials.

Symptoms of Chronic Inflammation in the Body: Early Warning Signs Explained

Inflammation is a natural defense mechanism that helps the body fight infections and heal injuries. However, when inflammation persists for months or even years without a clear cause, it becomes chronic. Chronic inflammation can silently damage tissues and increase the risk of serious diseases.

In India, rising cases of lifestyle diseases such as diabetes, heart disease and autoimmune disorders are often linked to long-term inflammatory processes. Recognizing the symptoms of chronic inflammation in the body is essential for early prevention and treatment.

 

What Is Chronic Inflammation?

Acute inflammation is short-term and occurs in response to injury or infection. Chronic inflammation, on the other hand, is:

  • Persistent
     

  • Low-grade
     

  • Often symptomatically subtle
     

  • Linked to long-term health conditions
     

It may occur due to unhealthy lifestyle habits, stress, obesity or underlying disease.

 

Common Symptoms of Chronic Inflammation

1. Persistent Fatigue

Ongoing tiredness that does not improve with rest may indicate systemic inflammation.

Inflammatory chemicals in the body can interfere with energy production.

 

2. Joint and Muscle Pain

Unexplained pain, stiffness or swelling in joints may suggest inflammatory conditions such as arthritis.

Pain may:

  • Last for weeks
     

  • Worsen in the morning
     

  • Occur without injury
     

 

3. Digestive Issues

Chronic inflammation may affect the gut, leading to:

  • Bloating
     

  • Diarrhea or constipation
     

  • Abdominal discomfort
     

  • Food sensitivities
     

Gut health and immune function are closely connected.

 

4. Frequent Infections

A weakened immune response due to chronic inflammation may result in:

  • Recurrent colds
     

  • Slow wound healing
     

  • Persistent sore throat
     

 

5. Skin Problems

Inflammatory skin conditions include:

  • Acne
     

  • Eczema
     

  • Psoriasis
     

  • Rashes
     

Persistent skin issues may reflect internal inflammation.

 

6. Brain Fog and Mood Changes

Inflammation can affect brain function, causing:

  • Difficulty concentrating
     

  • Memory issues
     

  • Irritability
     

  • Low mood
     

Mental and physical health are interconnected.

 

7. Unexplained Weight Changes

Inflammation may disrupt metabolism, leading to:

  • Abdominal weight gain
     

  • Difficulty losing weight
     

Obesity itself can further promote inflammation.

 

Causes of Chronic Inflammation

Common contributing factors include:

  • Poor diet high in processed foods
     

  • Excess sugar intake
     

  • Smoking
     

  • Alcohol abuse
     

  • Chronic stress
     

  • Lack of exercise
     

  • Sleep deprivation
     

  • Environmental pollution
     

Addressing these factors is essential for prevention.

 

Diseases Linked to Chronic Inflammation

Long-term inflammation is associated with:

  • Type 2 diabetes
     

  • Cardiovascular disease
     

  • Cancer
     

  • Autoimmune disorders
     

  • Fatty liver disease
     

  • Alzheimer’s disease
     

Early intervention reduces risk significantly.

 

How to Reduce Chronic Inflammation Naturally

1. Adopt an Anti-Inflammatory Diet

Include:

  • Fresh fruits and vegetables
     

  • Whole grains
     

  • Nuts and seeds
     

  • Fatty fish
     

  • Olive oil
     

Avoid processed foods and excessive sugar.

 

2. Exercise Regularly

Moderate physical activity lowers inflammatory markers.

Aim for at least 30 minutes daily.

 

3. Manage Stress

Chronic stress increases inflammatory hormones.

Practice:

  • Meditation
     

  • Yoga
     

  • Deep breathing exercises
     

 

4. Improve Sleep

7–8 hours of quality sleep supports immune regulation.

 

5. Maintain Healthy Weight

Reducing excess body fat lowers inflammation levels.

6. Avoid Smoking and Limit Alcohol

Both habits promote inflammatory responses in the body.

 

When to Seek Medical Advice

Consult a healthcare professional if you experience:

  • Persistent fatigue
     

  • Joint swelling
     

  • Recurrent infections
     

  • Unexplained pain
     

  • Long-lasting digestive problems
     

Blood tests such as C-reactive protein (CRP) may help assess inflammation levels.

 

Chronic Inflammation in the Indian Context

Rapid urbanization, sedentary lifestyle and dietary shifts in India have contributed to increasing inflammatory-related diseases. Public awareness about preventive measures can significantly reduce healthcare burden.

Early lifestyle changes play a crucial role in improving long-term outcomes.

 

Conclusion

Chronic inflammation may present subtle symptoms such as fatigue, joint pain, digestive issues and brain fog. Although often overlooked, long-term inflammation can increase the risk of serious diseases.

Adopting healthy eating habits, regular exercise, stress management and adequate sleep can help reduce inflammation naturally. Recognizing early warning signs and seeking medical advice when needed ensures better long-term health.

Taking proactive steps today can prevent major complications tomorrow.
