Asymptomatic COVID infections – are you safe?

Patients with COVID usually exhibit signs of coughing, fever, and fatigue. This can develop into further respiratory problems including difficulty breathing, pneumonia in both lungs, and in severe cases the need to ventilate a patient in an intensive care setting. But what if you are asymptomatic? Do you need to worry? Surely you get the benefits of immunity without the dangers of life-threatening symptoms.

In our previous blog, we discussed how a study showed 41% of people with COVID were asymptomatic. However, they had the same viral load as their symptomatic counterparts. This paper published in Nature Medicine suggests that even the asymptomatic patients developed signs of lung inflammation without showing any outward symptoms. Could asymptomatic patients still be damaged by COVID? It's not easy to study this subset of patients, as they do not get tested routinely or present to hospital for examination or investigation.

This study looked at 37 individuals in the Wanzhou District who were diagnosed with COVID via swab test but did not show any symptoms before the test or during hospitalization. These patients were found through the extensive contact tracing program set up in Central China. Whilst in hospital 57% showed abnormalities in the lung fields on a CT scan, including the “ground glass” appearance classic for COVID pneumonia. These changes could be due to fluid or blood in the area or due to inflammation caused directly by the infection.

What does this mean for the individual in the long term? This is difficult to say, especially since COVID has only been around for a few months so long term follow up is simply impossible to state accurately. Depending on the size and severity of the inflammation it may resolve spontaneously with no lasting damage, or the inflammation could cause scarring of the lung tissue that only becomes evident several years or decades down the line. It's difficult to tell.

The study also looked at two other factors in these patients. Compared to their symptomatic counterparts, asymptomatic patients were found to shed viral particles for several more days. It is unclear the significance of this, or whether this makes them more infective or prone to transmitting the infection for a longer period of time. It does add support to the theory asymptomatic people should not believe themselves exempt from spreading the infection.

Secondly, the study looked at the prevalence of antibodies present in the patient's blood. These antibodies can be used as a surrogate for immunity. In theory, after infection occurs our body has the ability to rapidly produce these antibodies against the virus in the event of a second infection. This would neutralize the infection before it could develop into a serious disease.

Looking at these antibodies the researchers found antibody levels against the SARS and MERS virus to last over 2 years. However, against SARS-CoV-2, the antibody levels fall within 2-3 months, providing only a short duration of immunity. This is worrisome for individuals and countries hoping to achieve herd immunity or at least immunity to the virus after a mild or asymptomatic infection.

So what should we take away from this? Perhaps an asymptomatic infection is not the perfect scenario. Damage does occur to your lungs, albeit temporary damage. You are still able to spread it to vulnerable people. And your immunity may not last as long as other infections.

Therefore be safe. Maintain social distancing, follow government advice on wearing a mask. And if you can, avoid excessive socializing or close contact with lots of other people. The virus hasn’t gone away, and it is still dangerous.

Virtual Cooking Class with a Dietitian: Why It’s a Powerful Corporate Wellness Benefit

Virtual Cooking Class with a Dietitian: Why It’s a Powerful Corporate Wellness Benefit

Corporate wellness programs in India are undergoing a meaningful transformation. What once revolved primarily around annual health checkups and gym memberships is now shifting toward sustainable lifestyle-based interventions. Among these, the virtual cooking class with a dietitian has emerged as one of the most practical and high-impact wellness initiatives for modern workplaces.

Poor dietary habits are a leading contributor to lifestyle-related conditions such as diabetes, obesity, hypertension, and heart disease. According to the Indian Council of Medical Research (ICMR) and the National Family Health Survey (NFHS-5), a significant proportion of India’s working population consumes excess refined carbohydrates, sugar, and unhealthy fats, while falling short on protein, fibre, and essential micronutrients.

For corporate wellness initiatives to create lasting impact, they must move beyond awareness and actively support behaviour change. Dietitian-led virtual cooking classes address this gap by turning nutritional knowledge into daily practice.

 

Why Nutrition Is a Critical Corporate Wellness Priority

1. Rising lifestyle disease burden among employees

ICMR data highlights the growing health challenge within India’s workforce:

  • Over 100 million Indians live with diabetes

  • Nearly one in four adults has hypertension

  • Obesity rates are rising even among younger professionals
     

These conditions directly affect productivity, absenteeism, insurance claims, and long-term healthcare costs.

2. Desk-bound and remote work culture

Sedentary routines, irregular meal timings, and reliance on processed or convenience foods have become common in corporate environments, especially with hybrid and remote work models.

3. Knowledge does not translate into action

Many employees are aware of what constitutes healthy eating but struggle to apply this knowledge in everyday cooking. Virtual cooking classes bridge this gap by offering hands-on, real-world guidance.

 

What Is a Virtual Cooking Class with a Dietitian?

A virtual cooking class with a dietitian is an interactive online session led by a qualified nutrition professional who:

  • Demonstrates healthy, practical recipes

  • Explains ingredient choices and substitutions

  • Teaches portion control and meal balance

  • Addresses common dietary myths

  • Answers real-time participant questions
     

Unlike generic cooking shows or wellness webinars, these sessions are evidence-based and aligned with preventive health goals. They are designed specifically for corporate audiences, ensuring simplicity, cultural relevance, and scalability.

 

Why Virtual Cooking Classes Work Better Than Traditional Nutrition Talks

1. Practical skill-building

Employees learn how to:

  • Plan balanced meals

  • Cook quick, healthy dishes

  • Reduce excess sugar, salt, and oil

  • Read food labels with confidence
     

Skill-based learning leads to stronger habit formation than passive education.

2. Higher engagement and participation

Interactive cooking sessions are:

  • More engaging than lecture-style talks

  • Suitable for virtual and hybrid teams

  • Inclusive across age groups and roles
     

Participants actively cook, ask questions, and engage rather than passively listening.

3. Cultural relevance

Dietitians tailor recipes to Indian food habits, regional preferences, and household realities, making healthy eating feel practical and sustainable rather than restrictive.

 

Key Benefits for Employees

Improved daily nutrition

Employees gain confidence in preparing balanced, nourishing meals at home.

Better energy and focus

Stable blood sugar levels and improved nutrient intake support sustained energy and mental clarity during work hours.

Reduced lifestyle disease risk

WHO and Lancet research confirms that dietary improvements significantly reduce the risk of chronic diseases.

Stress reduction

Cooking itself can be therapeutic, contributing positively to mental wellbeing.

Family-wide impact

Healthy habits learned by employees often influence household food choices, extending benefits beyond the workplace.

 

Why Employers Benefit from Virtual Cooking Classes

1. Reduced absenteeism

Healthier employees tend to experience fewer illness-related absences.

2. Improved productivity

Better nutrition supports cognitive performance, stamina, and focus.

3. Lower long-term healthcare costs

Preventive nutrition initiatives reduce the burden of chronic disease-related claims.

4. Stronger wellness culture

Interactive and practical programs demonstrate genuine employer commitment to employee wellbeing.

5. High return on investment

Compared to large-scale medical interventions, virtual cooking classes are cost-effective, scalable, and easy to implement.

EY–FICCI corporate wellness reports consistently show that nutrition-focused preventive programs deliver higher engagement and long-term impact.

 

Topics Commonly Covered in Corporate Cooking Classes

  • Balanced Indian meals
    Focus on protein, fibre, and micronutrient adequacy

  • Quick workday recipes
    Healthy meals prepared in under 30 minutes

  • Disease-preventive diets
    Heart-healthy, diabetes-friendly, and weight-conscious cooking

  • Smart ingredient swaps
    Replacing refined grains, excess oil, and added sugar

  • Portion control techniques
    Understanding serving sizes without calorie obsession

  • Reading food labels
    Identifying hidden sugar, sodium, and trans fats

     

 

How Virtual Cooking Classes Support Preventive Healthcare

Preventive healthcare focuses on addressing risk factors before disease develops, and nutrition plays a central role in this approach.

According to WHO and NITI Aayog:

  • Dietary modification is among the most cost-effective preventive strategies

  • Workplace interventions significantly influence adult eating habits
     

Virtual cooking classes help:

  • Reinforce preventive screening insights

  • Support chronic disease management

  • Improve adherence to dietitian recommendations
     

 

Role of AI-Guided Insights in Corporate Nutrition Programs

Modern wellness programs increasingly use data-driven tools to strengthen impact. AI-enabled health insights can:

  • Identify common nutritional gaps across employee populations

  • Personalise dietary recommendations

  • Support dietitians with evidence-based insights

  • Track long-term wellness outcomes
     

This ensures cooking sessions are aligned with real employee health needs rather than generic advice.

 

Why Virtual Delivery Works Best for Corporates

  • Easy scalability across multiple locations

  • No physical infrastructure required

  • Ideal for remote and hybrid teams

  • Flexible scheduling

  • Consistent quality delivery
     

Virtual formats ensure uniform wellness experiences regardless of employee location.

 

Long-Term Impact on Corporate Wellness

Organisations that consistently implement nutrition-focused wellness initiatives observe:

  • Higher employee engagement

  • Improved biometric health indicators

  • Reduced burnout

  • Stronger employer branding
     

Lancet workplace health studies indicate that nutrition-based interventions show measurable benefits within 6–12 months.

 

Conclusion

A virtual cooking class with a dietitian is more than a wellness activity—it is a powerful preventive health intervention. By equipping employees with practical nutrition skills, these sessions drive meaningful behaviour change, reduce lifestyle disease risk, and support long-term wellbeing. For organisations seeking impactful, scalable, and evidence-based corporate wellness solutions, dietitian-led virtual cooking classes represent a forward-thinking investment in workforce health.
