COVID-19 Variant: What We Know About This New Mutation

COVID-19 Variant: What we know about this new mutation

In early December a new variant of COVID -19 was detected in the UK, raising concerns across the world. SARS-CoV-2 has already significantly impacted the world, with 84 million cases worldwide and nearly 2 million deaths. Could the new variant cause further havoc? Is it something we should be worried about? Today we will have a look at what we know so far about the virus.

MUTAGENESIS

To start with we should go over viral mutations. Unlike complex organisms, viruses are highly prone to genetic mutations, even more than bacteria. All organisms including humans, birds, even worms, are prone to mutations as well. However due to their complexity, there is much higher risk of mutations causing significant problems with their cellular and genetic processes, problems that are often incompatible with life, or lead to cancer. For this reason, there are significant genetic roadblocks present to prevent such mutations from occurring.

Viruses on the other hand have genetic replication machinery of poor “quality”, prone to introducing mutations. Since they replicate quickly, with little care on which viral particles survive, it matters little if hundreds of viruses do not survive, as further thousands will and continue to spread in their host. It is for this reason we have such difficulty treating viruses or making viruses against them .

COVID VARIANT

The variant was first picked up by the COVID-19 Genomics UK consortium, which undertakes random genetic sequencing of positive COVID-19 samples across the UK. Since April they have sequenced 140,000 virus genomes, to identify and track outbreaks across the UK. The strain was first identified in September and sequenced in early October. However, the significance of this strain was not realized until the end of the year. By 13th December 1108 cases had been identified across 60 different locations, though the true number is likely much higher. In Norfolk, it accounts for nearly 20% of all samples.

17 Variations have been identified, most significantly in the spike protein the virus uses to bind to the ACE2 receptor found in the lungs. Changes in this protein may have resulted in it being more infectious and spreading more quickly between people. A review of current evidence has shown the rate of transmission was 71% higher than the other variants and may also have a much higher viral load. This has given it an advantage over the other COVID-19 strains- it has already been detected in South Africa, Europe, and America, and it is likely to become the dominant global strain in the near future.

It appears children are more susceptible to catching this virus. The virus propagated at a time when schools were open and running, whilst the rest of the country remained in lockdown. This may have provided a larger pool of children for the virus to spread in, resulting in this change. However, this does not mean that the virus “attacks” children, rather it is able to attach to ACE2 receptors in children’s lungs with greater ease and spread quickly.

VACCINE

The most important question on everyone’s mind – will the vaccine be effective against this new strain? If not, lockdown rules may be extended until new vaccines are discovered, and by then newer strains may leapfrog ahead and make the new vaccines irrelevant again.

So far experts believe that the new variant is unlikely to make vaccines ineffective. The vaccines all produce antibodies against the viral spike protein, but so far it appears the mutation has not changed the shape or function of the spike protein enough for antibodies to fail against it. The antibodies should be able to recognize enough sites on the spike protein to successfully attach, neuter the protein, and present the virus for destruction by the body’s immune system. Unfortunately, it will take some time to fully understand the effects of the mutation, though we can remain hopeful for now

Walking Meetings via Voice Chat: A Smarter Way to Boost Health and Productivity in Remote Teams

Remote work has transformed how teams collaborate, but it has also increased sedentary behaviour. Long hours of sitting in front of screens contribute to fatigue, musculoskeletal pain and reduced mental focus. In this context, walking meetings conducted via voice chat have emerged as a simple yet effective corporate wellness practice that aligns productivity with health.

Walking meetings do not require additional time, special equipment or complex planning. They simply reimagine how meetings are conducted.

The Sedentary Challenge in Remote Work

According to WHO and ICMR data:

prolonged sitting increases the risk of heart disease, diabetes and musculoskeletal problems
remote employees often sit longer than office-based workers
screen fatigue negatively affects mental health and productivity

Traditional video meetings unintentionally reinforce inactivity.

What Are Walking Meetings?

Walking meetings are conversations held while participants walk instead of sitting.

In remote settings, these meetings:

are conducted via voice calls
eliminate the need for video screens
allow participants to move freely

They are ideal for one-on-one discussions, team check-ins and brainstorming sessions.

Why Voice Chat Works Best for Walking Meetings

Voice-only meetings:

reduce screen dependency
allow safer movement
encourage active listening

Without visual distractions, participants often engage more deeply in conversation.

Health Benefits of Walking Meetings

Reduced Sedentary Time

Even short walks help:

improve blood circulation
reduce stiffness
activate muscles

WHO recommends breaking prolonged sitting every 30–60 minutes.

Cardiovascular Support

Regular walking:

improves heart health
lowers blood pressure
supports metabolic health

Incorporating movement into meetings contributes to daily activity goals.

Musculoskeletal Relief

Walking reduces:

neck and back strain
shoulder tension
joint stiffness

This is particularly valuable for desk-bound employees.

Mental Health and Cognitive Benefits

Improved Focus and Creativity

Movement increases blood flow to the brain.

Studies cited by Lancet show that walking enhances:

problem-solving
creativity
memory recall

Many people report clearer thinking during walking discussions.

Stress Reduction

Walking helps:

lower cortisol levels
improve mood
reduce mental fatigue

This supports emotional wellbeing in high-pressure work environments.

Productivity Benefits for Organisations

Walking meetings:

reduce meeting fatigue
improve engagement
shorten meeting duration due to focused discussion

Employees often return to tasks feeling refreshed rather than drained.

Cultural Shift Toward Wellness-Oriented Work

Encouraging walking meetings signals:

trust in employees
commitment to wellbeing
flexibility in work culture

This improves morale and retention.

How to Implement Walking Meetings in Remote Teams

Simple steps include:

designating certain meetings as “audio-only”
encouraging participants to walk indoors or outdoors
keeping meetings concise
sharing agendas in advance

Clear guidelines ensure safety and effectiveness.

Safety and Practical Considerations

Best practices include:

avoiding walking in unsafe or crowded areas
using earphones for clarity
walking at a comfortable pace
pausing movement when taking notes

Inclusivity is important—walking should be optional, not mandatory.

Who Benefits Most from Walking Meetings?

Walking meetings are especially helpful for:

remote workers
hybrid teams
roles with frequent discussions
employees experiencing screen fatigue

They are less suitable for data-heavy presentations.

Walking Meetings as Part of Corporate Wellness Programs

Walking meetings complement:

ergonomics initiatives
mental health programs
physical activity challenges

They integrate wellness into daily workflows rather than adding extra tasks.

Long-Term Impact on Workplace Health

Over time, organisations adopting movement-friendly practices observe:

reduced burnout
improved energy levels
healthier work routines

Preventive health strategies are most effective when embedded into daily habits.

Role of Preventive Healthcare Awareness

NITI Aayog and WHO emphasise lifestyle modification as a core preventive health strategy.

Walking meetings align perfectly with this approach by:

reducing inactivity
promoting movement
supporting mental wellbeing

Small changes deliver cumulative benefits.

Conclusion

Walking meetings conducted via voice chat are a practical, low-cost and highly effective way to improve employee health and productivity in remote teams. By replacing sedentary meetings with movement-based conversations, organisations can reduce screen fatigue, enhance focus and support long-term wellbeing. In a remote-first world, walking meetings represent a smarter way to work—where productivity and health move forward together.
