Covid Delta Variant: Virus Is Changing And We Need To Change Too!

Delta Variant: Virus is changing and we need to change too!

The entire world is changing its overall strategy on the coronavirus pandemic this week. Masks are back, vaccine mandates are looming, and officials have sounded more worried than they have in months. Employees must wear a mask throughout the day at work while also keeping distance from others and submitting to a virus test once per week for safety reasons driving these changes as two factors: The large number who remain unvaccinated due to fears about vaccines' health effects combined with Delta variant's rapid spread across Europe over recent weeks which forces authorities around the world into immediate action against disease threat."

The Delta variant, originally known as B.1-617.2 has been around since last year but in recent months it's become the fastest spreading virus of all time according to many experts and scientists who are researching this issue more now than ever before. The US Centers for Disease Control (CDC) have also said that COVID-19 cases have increased over 300% nationally from June 19th to July 23rd along with parallel increases in hospitalizations and deaths are driven by the highly transmissible B: 1 617 2 delta variant which is one of a few reasons why they're so concerned about this new strain because there doesn't seem like any way we can stop or cure it yet if at all.

The Delta variant, originally known as B.1.617.2, has been around since last year but in recent months it's become speedily dominant with an 80% share of newly diagnosed cases across the US according to Centers for Disease Control and Prevention (CDC). The CDC says there have also been "parallel increases" in hospitalizations and deaths which are being driven by this new highly transmissible strain - COVID-19 or what is now better described as the Delta infection

Let's understand what the Delta variant is: a virus that has been around since late last year but in recent months it has become speedily dominant in many countries. It accounts for more than 80% of newly diagnosed cases.

The Delta variant is more transmissible in some studies, but not all. One CDC document indicates the Delta variant to be as contagious as chickenpox with each infected person infecting a few others. This difficult number to check because it requires much testing which has yet been done

The Delta variant is more transmissible than traditional coronavirus, but we don't know by how much. The CDC estimates that the new virus might be about 60-200% as contagious as chickenpox with each infected person infecting eight or nine others on average while a typical case of common cold only has an infection rate of two other people per affected individual. One paragraph from one CDC document indicates that this number could even be higher and since it's difficult to determine exact statistics without comprehensive testing, there are multiple possible outcomes for these estimations.

In a recent presentation, the CDC has noted that vaccines prevent more than 90% of severe diseases but may be less effective at preventing infection or transmission. However, if you're vaccinated with one of two currently approved COVID-19 mRNA vaccine brands (Pfizer and Moderna), then evidence suggests they are highly effective against hospitalization and death for various strains such as Alpha (B.1.1.7) Beta (B 1/351), Gamma( P 1 ), Delta( B/617).

The presentation notes that vaccines are less effective at preventing infection or transmission and sometimes can lead to breakthrough outbreaks in communities despite vaccination. To help combat these effects, the site also noted Moderna's mRNA COVID-19 vaccine is highly effective for many strains of measles including Alpha (B.1.1), Beta (B2) Gamma (P), Delta B(2).

A recent study has shown that the effectiveness of vaccines against certain variants may be lower than previously anticipated. The CDC is urging for ongoing monitoring to ensure appropriate vaccination strategies are developed and implemented with these new findings in mind.

Data suggest that the vaccine is less effective against confirmed infection and symptomatic disease caused by variants of influenza. Ongoing monitoring should be done to ensure that vaccines are still as effective in fighting off Delta variant though lab tests indicate immune response generated should cover it.

Delta has a unique set of mutations that may allow it to evade the human immune system and be more efficient in infecting cells. Delta's changes are limited to its receptor-binding domain, which allows for tight connections with the host cell while also helping this virus escape detection by hiding from our body's natural defenses like antibodies. One change is believed to help make these bonds tighter--making us sicker faster!

The delta virus has at least three mutations on a structure that is called the receptor-binding domain--the part of the disease-causing agent responsible for docking into human cells it infects. It may help evade detection by our immune system, and one mutation, in particular, could make it bind more tightly to infected cells.

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.

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
