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“these are preliminary reports that have not been peer-reviewed.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 Secondly it is not peer reviewed.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.

How to Prevent Food Poisoning in Monsoon

Monsoon brings relief from the heat—but along with cool breezes and rains come increased chances of infections, especially food poisoning. The high moisture in the air creates a perfect breeding ground for bacteria, making food more likely to spoil and cause illness.

In this article, we’ll help you understand how to stay safe with easy, practical tips on how to prevent food poisoning in monsoon.

Why Is Food Poisoning So Common in Monsoon?

The damp and humid conditions during the rainy season promote bacterial and fungal growth. This contamination can easily affect the food we eat and the water we drink.

Common causes of food poisoning in monsoon include:

Eating contaminated street food
Drinking unfiltered or untreated water
Improper storage or refrigeration
Eating undercooked or reheated leftovers

Symptoms can range from mild stomach pain to vomiting, diarrhea, and fever—and can become serious if not treated on time.

How to Prevent Food Poisoning in Monsoon: Easy Tips

Let’s go step by step into what you should do (and not do) during this season to avoid foodborne illness:

1. Avoid Street Food and Raw Salads

Street vendors often use unclean water and keep food exposed to dust, flies, and pollution. In monsoon, this risk becomes even higher.

What to avoid:

Chaat, golgappas, sandwiches from carts
Cut fruits or raw vegetables sold outside
Juices from roadside stalls

Instead, eat home-cooked meals where you can control the hygiene.

2. Drink Only Boiled or Purified Water

Unfiltered water is a major cause of stomach infections during monsoon. Make sure your drinking water is:

Boiled for 10 minutes, or
Filtered using a RO/UV purifier, or
Packaged from a trusted brand

Avoid consuming water-based drinks like sherbets or ice made with unclean water.

3. Eat Fresh and Hot Food

In monsoon, bacteria multiply quickly. Avoid eating food that has been left out for hours.

Tips:

Eat freshly cooked meals while still warm
Avoid reheating food multiple times
Don't leave cooked food at room temperature for more than 2 hours

4. Refrigerate Perishables Quickly

Your fridge is your best friend in this season—but only if you use it right.

Refrigeration tips:

Store cooked food in airtight containers
Don't keep raw meat and vegetables together
Use leftovers within 24 hours
Check for expired or spoiled food regularly

5. Clean Fruits and Vegetables Properly

Rainwater often brings mud and germs to fresh produce. Even greens from the market can carry bacteria and insect eggs.

Cleaning tips:

Wash produce thoroughly with clean water
Use salt water or vinegar soak for 10–15 minutes to disinfect
Peel fruits like mangoes and bananas before eating
Avoid leafy vegetables that are difficult to clean, like spinach and lettuce

6. Practice Good Kitchen Hygiene

Contamination often starts in your kitchen.

Hygiene habits to follow:

Wash hands before and after handling food
Keep utensils and chopping boards dry and clean
Don't let water collect on kitchen surfaces
Wash dish cloths and sponges regularly

Related Health Checkups to Consider

If you're experiencing stomach problems or want to monitor your digestive health during monsoon, these lab tests (available via SecondMedic powered by Thyrocare) may help:

???? Complete Blood Count (CBC)

Checks for infections or inflammation.

???? Stool Routine & Culture Test

Detects bacterial infections, parasites, or digestive disorders.

???? CRP Test (C-Reactive Protein)

Shows whether your body is fighting an infection.

???? Food Intolerance Test

For people with recurring food-related digestive issues.

All tests come with home sample collection and online report access at www.secondmedic.com.

Foods You Can Eat During Monsoon

Here are some healthy, safe food choices during the rainy season:

Warm soups and khichdi – light and easy to digest
Steamed vegetables – safer than raw
Ginger tea – helps digestion
Turmeric milk – natural immunity booster
Boiled eggs or well-cooked lean meat

Avoid oily, uncooked, or refrigerated food that’s more than a day old.

Conclusion

Monsoon brings beauty, but also bacteria. Staying safe is all about being smart with your food and water. By following simple hygiene rules and eating fresh, clean food, you can enjoy the season without worrying about stomach issues.

Be alert, eat smart, and protect your family by following these tips on how to prevent food poisoning in monsoon.
