COVID-19 MYTHBUSTER

MYTHBUSTER

There are many rumours, theories and suggestions that are being spread on Facebook, WhatsApp and social media. Most of these have no truth to them, do not work as treatment, or can be dangerous to your health. They use language that makes them sound scientific, and usually claim to come from a reputable institute, medical journal or doctor. Many people will automatically trust this, without questioning whether the legitimacy of the advice given. We have covered the dangers of these social media posts in our blog: https://www.secondmedic.com/blogs/the-dangers-of-social-media-blind-forwards secondmedic blog

Here we will go over some common myths about COVID-19 and Coronavirus that you will encounter. If you have come across any new myths or theories, or you want to check something you have read or been sent, email us at info@secondmedic.com

5G mobile networks DO NOT spread COVID-19

This is a myth that has been spreading recently, claiming that the new 5G towers being erected are spreading COVID-19. This is not true and there is no scientific evidence to support this.

Coronavirus spreads on small droplets that are coughed up by infected people. It is possible to prove this by looking at these droplets under an electron microscope. 5G networks use radio waves to operate, similar to 4G networks and other mobile network technologies. Radio waves cannot carry or transmit viral particles.

Another theory is that 5G radio waves cause damage to the human body. Radio waves have very little energy and pass through the human body without causing any harm. They have less energy than sunlight, and we are exposed to sunlight daily without harm.

People are claiming that 5G and coronavirus arrived at the same time, and so must be connected. Simply linking two things together does not mean one causes another. 5G technology does not exist in many countries with COVID-19, and yet some of these countries have been hit harder than well developed countries.

Destroying masts because of this conspiracy theory is harmful, as these masts carry mobile network signals that allow people to phone in emergencies, and for emergency responders to communicate with hospitals, fire stations and the police. Destroying these masts can cause serious harm to others.

Coronavirus WAS NOT developed in a laboratory as a weapon by China/Russia/US

Multiple reputable labs and universities across the world have analysed the coronavirus responsible for COVID-19, and have determined there is no evidence it was produced by humans. It is very similar to pre-existing coronaviruses that have caused the SARS and MERS pandemics. Conspiracy theories such as these are being used to shift the blame to others and gain political points in the news, rather than focus on what is important – preventing the spread of the virus and treating those that are ill.

Holding your breath for 10 seconds or more without coughing DOES NOT prove you are free of COVID-19

One popular test that has spread on WhatsApp states you can see whether you have COVID-19 with one simple test. If you can hold your breath for more than 10 seconds without coughing or feeling any discomfort, you do not have COVID-19 and are safe. It says that COVID-19 causes fibrosis in your lungs and this can stop you from holding your breath. There is no evidence supporting this theory.

Many people who have had COVID-19 can hold their breath for 10 seconds, and many people who are virus free are unable to hold their breath. The only way to determine if you have had the virus is through a nose or throat swab to check for the virus. If you have symptoms of COVID-19 (fever, dry cough, feeling tired, shortness of breath), you should assume you have the virus and isolate yourself.

Drinking alcohol DOES NOT protect you against COVID-19

Alcohol is a disinfectant. Washing your hands with alcohol based hand gels can destroy the bacteria. However drinking alcohol is not the same. When you drink alcohol it is processed by your body to release energy, and it loses its disinfectant properties. Drinking too much alcohol can cause alcohol poisoning and damage your liver.

Hundreds of people have died as a result of drinking methanol, a dangerous form of alcohol.

Spraying alcohol over your body will kill any virus that is on your skin. But you should only use alcohol based hand gels, as they have the right amount of alcohol that does not harm your skin. Alcohol based gels will not cure COVID, as the virus causing the symptoms is in your lungs, not your skin.

Drinking bleach DOES NOT protect you against COVID-19. IT CAN KILL YOU

Just like alcohol, disinfectants and bleach can kill the virus if sprayed onto a surface that has the virus. But drinking them is highly dangerous and can be lethal. If ingested bleach will destroy your stomach just like it destroys the virus, and it will continue to destroy your body depending on how much is ingested.

DO NOT DRINK BLEACH.

Similarly do not spray disinfectant or bleach on your skin. It is highly irritating and can cause a lot of damage, especially if it gets in your eyes, nose or mouth.

Importance of Regular Health Checkups: Early Detection Saves Lives

In today’s fast-paced lifestyle, many individuals prioritise work and family responsibilities while neglecting their own health. However, understanding the importance of regular health checkups is critical for preventing serious medical conditions. Many diseases develop silently without noticeable symptoms, making routine screening essential for early diagnosis and effective treatment.

According to the Indian Council of Medical Research (ICMR), non-communicable diseases such as diabetes, hypertension and cardiovascular conditions are rising across India. Early detection through preventive checkups significantly reduces complications and mortality.

What Are Regular Health Checkups?

Regular health checkups involve:

routine blood tests
blood pressure monitoring
cholesterol screening
organ function tests
lifestyle risk assessments

These assessments help identify abnormalities before they progress into severe conditions.

Why Preventive Healthcare Matters

Preventive healthcare focuses on:

identifying risk factors
detecting disease early
preventing complications

The World Health Organization states that preventive care reduces long-term healthcare burden and improves life expectancy.

Early Detection of Chronic Diseases

Diabetes

India has over 100 million people living with diabetes, according to ICMR data. Many individuals are unaware until complications arise.

Early screening detects:

elevated blood sugar
insulin resistance

Hypertension

NFHS-5 reports that nearly one in four adults in India has hypertension.

Regular monitoring prevents:

stroke
heart attack
kidney damage

Heart Disease

Cholesterol screening identifies risk before symptoms appear.

Timely lifestyle modifications reduce cardiovascular events.

Cancer Screening and Survival Rates

Screenings such as:

mammograms
Pap smears
colon cancer screening

significantly improve survival when disease is detected early.

Monitoring Organ Function

Regular checkups assess:

liver health
kidney function
thyroid levels

Silent organ dysfunction can be detected early.

Benefits of Regular Health Checkups

Reduced Healthcare Costs

Treating advanced disease is more expensive than preventive care.

Improved Quality of Life

Early treatment reduces long-term complications.

Peace of Mind

Knowing health parameters are normal reduces anxiety.

Better Lifestyle Decisions

Screening results motivate healthier habits.

Who Should Get Regular Health Checkups?

adults above 30 years
individuals with family history of chronic disease
smokers
overweight individuals
sedentary professionals

High-risk groups may require more frequent testing.

Frequency of Health Screenings

General recommendation:

Annual checkup for adults
Biannual or quarterly monitoring for high-risk individuals

Doctors personalise schedules based on medical history.

Corporate Health Checkups

Many organisations conduct:

workplace screening camps
employee wellness programs

These initiatives improve workforce productivity and reduce absenteeism.

Preventive Health in India

NITI Aayog highlights preventive healthcare as essential for reducing national disease burden.

Increasing awareness about routine checkups is critical.

Common Tests in Annual Health Packages

Complete blood count
Lipid profile
Fasting blood sugar
HbA1c
Liver function test
Kidney function test
Thyroid profile
Vitamin levels

These tests provide comprehensive health insight.

Addressing Common Misconceptions

Many people avoid checkups because:

they feel healthy
they fear results
they lack time

However, absence of symptoms does not mean absence of disease.

Lifestyle Diseases and Urbanisation

Urban lifestyles contribute to:

sedentary behaviour
poor diet
stress

Regular monitoring counters these risks.

Digital Health and Screening Accessibility

Online booking platforms and home sample collection make preventive care more accessible and convenient.

Technology supports proactive health management.

Building a Culture of Preventive Health

Encouraging:

annual screenings
family health awareness
workplace initiatives

creates healthier communities.

Conclusion

Understanding the importance of regular health checkups is essential for preventing chronic disease and improving life expectancy. Early detection of diabetes, hypertension, heart disease and other conditions allows timely treatment and reduces complications. Preventive healthcare is not an expense but an investment in long-term wellbeing. Scheduling routine screenings today can protect health and save lives tomorrow.
