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.

Indoor Cycles

Add Indoor Cycles or Scooters at Large Offices – Promote Movement During the Day

Corporate offices today are larger, more digitally connected and more sedentary than ever before. Employees spend extended hours seated at desks, in meetings or on screens. According to the World Health Organization, physical inactivity is among the top risk factors for global mortality. In India, rapid urbanisation and desk-based jobs have significantly increased sedentary behaviour.

One innovative workplace wellness strategy is to Add Indoor Cycles or Scooters at Large Offices – Promote movement during the day. This simple yet impactful initiative encourages daily physical activity within the office environment, helping reduce long-term health risks.

The Sedentary Workplace Problem

Large office campuses often require:

  • long walks between departments

  • elevator use for multiple floors

  • extended desk time

However, most employees still remain seated for more than 6–8 hours daily.

ICMR and NFHS-5 data show increasing prevalence of:

  • obesity

  • hypertension

  • diabetes

Sedentary habits contribute significantly to these conditions.

 

Why Movement During the Day Matters

Prolonged sitting affects:

  • metabolism

  • circulation

  • posture

  • heart health

Short bursts of activity improve:

  • blood flow

  • oxygen delivery

  • mental alertness

Encouraging movement throughout the day prevents metabolic slowdown.

 

How Indoor Cycles and Scooters Help

1. Break the Sitting Cycle

Indoor cycles placed in designated zones allow employees to:

  • pedal for 5–10 minutes

  • refresh during breaks

  • reduce continuous sitting

Scooters in large campuses encourage movement between departments.

 

2. Boost Energy Levels

Light physical activity stimulates:

  • endorphin release

  • improved circulation

  • mental clarity

Employees return to tasks with renewed focus.

 

3. Improve Cardiovascular Health

Regular low-intensity cycling helps:

  • regulate blood pressure

  • improve heart function

  • manage weight

Consistent activity reduces risk of heart disease.

 

4. Encourage Active Office Culture

Visible wellness initiatives create:

  • positive peer influence

  • cultural shift toward health

  • higher engagement

When movement becomes normalised, participation increases.

 

Impact on Productivity

Contrary to concerns, movement breaks:

  • improve concentration

  • reduce fatigue

  • enhance creativity

Research cited by global workplace health reports shows that active employees demonstrate better cognitive performance.

 

Suitable for Large Office Campuses

Large offices with:

  • multiple floors

  • wide corridors

  • campus layouts

can safely integrate scooters for short-distance mobility.

Indoor cycling stations can be placed in:

  • wellness corners

  • break rooms

  • near cafeterias

Accessibility encourages usage.

 

Addressing Safety and Practicality

To ensure safety:

  • provide clear guidelines

  • designate riding zones

  • encourage voluntary participation

  • maintain equipment regularly

Structured implementation ensures smooth integration.

 

Mental Health Benefits

Movement during the workday:

  • reduces stress

  • lowers cortisol levels

  • improves mood

Stress reduction contributes to better overall wellbeing.

 

Supporting Preventive Healthcare

Regular physical activity helps prevent:

  • metabolic syndrome

  • obesity

  • type 2 diabetes

  • hypertension

Preventive workplace initiatives reduce long-term health costs.

 

Encouraging Participation

Organisations can:

  • track voluntary participation

  • organise friendly cycling challenges

  • reward consistent engagement

Gamification increases motivation.

 

Complementing Other Wellness Initiatives

Indoor cycles and scooters can integrate with:

  • standing desks

  • walking meetings

  • stretch breaks

  • health screening programs

A multi-layered approach maximises impact.

 

Measuring Success

Metrics may include:

  • employee feedback

  • reduced absenteeism

  • improved wellness survey results

  • increased engagement scores

Data supports long-term continuation.

 

Economic Benefits for Employers

Preventive activity reduces:

  • sick leave

  • burnout

  • productivity loss

Healthy employees contribute more consistently.

 

Creating a Culture of Movement

Leadership participation encourages adoption.

When managers model active behaviour, employees follow.

Wellness becomes embedded in organisational identity.

 

Long-Term Impact

Encouraging daily movement leads to:

  • better cardiovascular health

  • improved metabolic function

  • reduced stress

  • enhanced workplace morale

Small, consistent actions create sustainable change.

 

Conclusion

Add Indoor Cycles or Scooters at Large Offices – Promote movement during the day is a forward-thinking corporate wellness strategy. By addressing sedentary habits directly within the workplace environment, organisations can reduce lifestyle disease risk, enhance productivity and foster a culture of health. Movement is not just exercise—it is preventive healthcare in action. When offices actively design for motion, they invest in the long-term wellbeing of their workforce.
