A Variant Of Concern: Omicron

A variant of Concern: Omicron

The World Health Organization has designated the strain, now named Omicron, as a variant of concern and said multiple studies are underway to monitor its development.

The Unknowns - Scientists are warning that the variant could be more contagious, but they don't really know for sure. They also worry about its effects on vaccine efficacy and severity of disease - we'll just have to wait until there's more research!
Where it has been identified - The variant has so far been identified in South Africa, Botswana, Hong Kong, and Belgium. A specimen from the first known case of the variant in South Africa was collected November 9, the WHO said Friday.
The number of variant cases - Now, the number of variant cases seems to be increasing in nearly every province of the country, the WHO said. South Africa has currently fully vaccinated less than 36% of its adult population and its rate of new vaccinations had fallen in recent days, according to the country's health department.
Cases Identified - South African officials also initially said there was one confirmed case in a traveler from South Africa to Hong Kong. Friday, Hong Kong health authorities identified a second case of the variant among returning travelers on the same floor of a designated quarantine hotel. Health authorities ordered at least 12 people in nearby rooms to undergo mandatory Covid-19 testing and two weeks of quarantine in a government center. Also on Friday, the Belgian government said an individual who had recently traveled from Egypt and was unvaccinated, tested positive for the variant, marking the first case in Europe.
High number of Mutations: South African genomic scientists said earlier this week the variant has an unusually high number of mutations, with more than 30 in the key spike protein -- the structure the virus uses to get into the cells they attack.
The concern: Scientists are concerned those mutations could make the variant more transmissible and could result in immune evasion. Scientists are working to find out whether the variant could evade immunity, saying its mutations can help hint or predict whether it will be the case.
Vaccine Efficacy: The million-dollar question is, is there a tiny hit to vaccine efficacy, or is there a large hit? we'll get some preliminary data probably in the next few days.
How it compares with other variants - While mutations -- and new variants -- of the virus are expected as it continues to spread, experts say there's more reason for concern with Omicron. As per the scientists they have seen a lot of variants pop up over the last five, six months, and most of them have not amounted to much but this looks different. It's acting differently, it looks like it's much more contagious than even the Delta variant." WHO officials also said in their statement Friday preliminary evidence suggests Omicron also poses a higher risk of reinfection, compared to other variants of concern.

What vaccine makers are saying

In a Friday news release, Moderna said it was rapidly working to test the ability of its vaccine to neutralize the variant, and data is expected in the coming weeks.

The strain includes mutations "seen in the Delta variant that are believed to increase transmissibility and mutations seen in the Beta and Delta variants that are believed to promote immune escape," Moderna said. "The combination of mutations represents a significant potential risk to accelerate the waning of natural and vaccine-induced immunity."

The Solution: If its current vaccine and booster are insufficient against the variant, one possible solution is boosting people with a larger dose, which Moderna said it is testing. The company is also evaluating two multivalent booster candidates to see if they provide better protection against Omicron -- both of which include some of the viral mutations present in the variant. Moderna said it is also testing an Omicron-specific booster. AstraZeneca also said it was looking to understand the impact Omicron has on its vaccine, which is not currently authorized for use in the US. A Johnson & Johnson spokesperson told CNN in a statement the company was also testing the effectiveness of its vaccine against Omicron.

Why Travel Restrictions?

Travel restrictions will buy governments some time to investigate the variant, but it's inevitable the strain will eventually appear and spread.

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.
