Corona Virus (COVID-19) Being Responsible

The world is in a state of panic with fear of Corona and perhaps rightly so. Official, semi-official and unofficial guidances are pouring in from all possible sources. Social media has been promoting the use of masks only for sufferers of Corona infection and those who are having symptoms of cough and fever. Some experts have gone to the extent of suggesting that the use of mask for members of the general public may even be harmful. It may promote a sense of complacency among people, a false sense of safety leading to negligence of other precautions. Masks may be so ill-fitting that the user has to touch it frequently to adjust it, which may lead to transmission of infection. The virus is supposed to be transmitted by droplets coughed out by the sufferers. The purpose of the mask used by these people is to stop passing on the droplets to others. While this notion seems to make sense, it may not be entirely true and the use of masks by people at large may still have some protective value. There may be people who are infected and not aware of it. Avoiding relatively close contact with such people at public places may not be easy in populous countries which are not locked down completely yet. Use of mask in that situation may provide some protection at least. After all the infected droplets need to be inhaled to cause further infection and a mask over the mouth and nostrils will prevent the inhalation to some extent. It seems, therefore, that discouraging people from using masks may be an irresponsible act. What should be emphasized instead is that using a mask is not the end of your responsibility towards protecting yourself and others. Other precautions are equally important. Following are a few examples:
1. If you have cough and/or fever, confine yourself indoors and avoid coming in contact with people, specially children, elderly and those with chronic illnesses.
2. Wash your hands well with soap and water frequently and certainly after touching anyone or anything.
3. Avoid touching your face and eyes unnecessarily.
4. Do not cough in the open or on your hands. Use a tissue or your sleeve instead. Bin the tissue immediately.
5. Avoid unnecessary travels.
6. Avoid public gatherings.
7. If you suspect you may be infected with Corona, do not use antibiotics, they will not be effective.
8. When interacting with strangers or those with cough/fever, stand at least three steps away.

Genetic Predisposition Testing India: Understanding Your DNA to Prevent Future Disease

Genetics plays a significant role in determining an individual’s risk for various diseases. In India, where chronic illnesses like diabetes, heart disease, cancer, and neurological disorders are increasing rapidly, genetic predisposition testing has emerged as a powerful preventive tool. It helps individuals understand inherited risk factors long before symptoms appear, allowing timely intervention.

SecondMedic offers guided genetic screening to help patients uncover DNA-based risks and take proactive control of their long-term health.

What Is Genetic Predisposition Testing?

Genetic predisposition testing analyzes a person’s DNA to identify mutations, variations, or inherited markers associated with increased disease risk. It does not diagnose a disease but reveals how likely an individual is to develop certain conditions.

What the test identifies:

Gene mutations
Family-linked disease patterns
Hereditary cancer markers
Metabolic and cardiovascular risks
Neurological conditions
Autoimmune predispositions

These insights help individuals and doctors make informed preventive health decisions.

Why Genetic Testing Is Growing in India

1. High prevalence of lifestyle and hereditary diseases

India is the diabetes capital of the world, and many metabolic disorders have genetic roots.

2. Increasing cancer burden

BRCA and other hereditary cancer syndromes are being detected more often.

3. Awareness about preventive healthcare

People want to act early rather than wait for disease onset.

4. Growth of digital healthcare

Easy access through telemedicine platforms like SecondMedic.

5. Rising chronic cases at younger ages

Genetic predispositions often accelerate early onset of disease.

What Diseases Can Genetic Testing Predict?

1. Cancer Risk

Includes hereditary cancers such as:

Breast
Ovarian
Colorectal
Prostate
Pancreatic

BRCA1, BRCA2, and Lynch syndrome genes are key markers.

2. Heart Disease & Hypertension

Genes that influence:

Cholesterol levels
Plaque formation
Blood pressure regulation

3. Diabetes

Genes that affect insulin sensitivity and metabolic function.

4. Obesity

Markers linked to appetite regulation and fat storage.

5. Neurological Disorders

Including Alzheimer’s, Parkinson’s, and epilepsy predispositions.

6. Autoimmune Diseases

Genes related to lupus, rheumatoid arthritis, and thyroid disorders.

7. Drug Response (Pharmacogenomics)

DNA determines how the body reacts to certain medications.

How Genetic Predisposition Testing Works

Step 1: Sample Collection

Usually saliva, blood, or buccal swab.

Step 2: DNA Sequencing

Advanced technology identifies variations in your genome.

Step 3: Risk Analysis

Gene mutations are mapped to known disease risks.

Step 4: Expert Interpretation

SecondMedic’s genetic counsellors and doctors review results.

Step 5: Preventive Plan

Includes recommended lifestyle changes, screenings, and monitoring.

Benefits of Genetic Predisposition Testing

1. Detect Risk Before Symptoms

Allows decades of preventive action.

2. Personalized Health Planning

Diet, exercise, and medical screening tailored to DNA.

3. Early Cancer Detection

Essential for women with hereditary breast/ovarian cancer risk.

4. Family Health Insights

Identifies conditions that may affect children and siblings.

5. Improved Treatment Outcomes

Knowing your risk helps doctors monitor you more closely.

6. Better Drug Selection

Pharmacogenomics ensures medications match your genetic profile.

Who Should Consider Genetic Testing?

People with family history of cancer
Individuals whose relatives had early heart attacks
Families with diabetes across generations
Women with breast or ovarian cancer history
Couples planning pregnancy
People with unexplained chronic conditions
Individuals wanting personalized preventive healthcare

Limitations of Genetic Testing

1. Not a diagnosis

It shows probability, not certainty.

2. Environmental and lifestyle factors still matter

Genes interact with habits and environment.

3. Requires professional interpretation

Raw results without counselling can be confusing.

SecondMedic ensures accurate guidance through experienced specialists.

How SecondMedic Supports Genetic Testing

1. End-to-End Genetic Screening

From sample collection to detailed analysis.

2. Expert Review

Genetic counselors and doctors explain every risk factor.

3. Personalized Preventive Plan

Nutrition, exercise, and screening based on DNA.

4. Confidential Reporting

All data is securely stored.

5. Integrated Preventive Tracking

Follow-up tests and monitoring for high-risk individuals.

Future of Genetic Testing in India

AI-based genome interpretation
Affordable whole-genome sequencing
Predictive analytics for early cancer
Family-wide health risk mapping
Integration with digital health IDs under ABDM

SecondMedic aims to make genetic screening widely accessible and scientifically guided.

Conclusion

Genetic predisposition testing India empowers individuals by revealing inherited disease risks long before symptoms develop. It supports preventive healthcare, early cancer detection, and personalized wellness planning. With platforms like SecondMedic offering expert-guided genetic testing, Indians can now take proactive control of their long-term health.
