The Hidden Curve: Why COVID-19 Still Demands Vigilance and Resilience

1. INTRODUCTION

The global focus has shifted. COVID-19 is no longer the front-page pandemic it once was but the virus remains very much alive in our daily lives. With new subvariants emerging, periodic surges in cases, and lingering uncertainties about immunity and long COVID, we are entering a phase that demands both vigilance and recalibration.

This blog offers a fresh snapshot of where COVID-19 stands today, and more importantly, how we should position ourselves, individually and institutionally, for resilience. Think of this as not just a health update, but a playbook for sustained precaution in a world where new viral waves are always possible.

2. WHAT IS THE CURRENT SITUATION?

Global & Regional Trends

According to the World Health Organization (WHO), after a relatively quiet start to 2025, COVID-19 circulation has accelerated. In multiple WHO regions, test positivity rates are rising again.  

Vaccination efforts continue to be essential. WHO currently emphasizes that variant-targeted vaccines can be deployed, and that delaying vaccination is not recommended for people at higher risk.  

India’s Scenario

• India is witnessing a resurgence: active case counts have been rising in several states. For example, by early June 2025, active COVID cases in India hit around 4,866 (Fortis Healthcare).

• Some states such as Kerala, Gujarat, West Bengal, and Delhi are among the more affected areas (Times of India).

• The uptick is being linked to multiple Omicron subvariants under monitoring, including NB.1.8.1, LF.7, and JN.1. These are not (yet) classified as Variants of Concern, but their transmissibility is being watched (Al Jazeera).

• Importantly, though more transmissible, current data does not strongly suggest increased severity compared to existing subvariants (Gavi). 

  
  

Key Observations

• COVID has begun settling into a cyclical pattern, somewhat analogous to seasonal respiratory viruses.

• Immunity (from infection or vaccination) is wanning over time, making reinfections and breakthrough infections more plausible.

• Many health systems and public health agencies are treating COVID as a respiratory disease within integrated surveillance systems, rather than a separate emergency.

3. UNDERLYING CHALLENGES & RISKS

Understanding the risks helps frame why precautions still matter:

1. Evolving Variants & Immune Escape

New variants (e.g. NB.1.8.1, XFG) are emerging via recombination and mutation. Some may partially evade existing immunity, even if not causing more severe disease (Gavi).  

2. Waning Immunity & Vaccine Gaps

Over time, antibody levels decline, and boosts or variant-updated vaccine formulations may be needed to maintain protection.

3. Heterogeneous Health Infrastructure

Regions with weaker public health systems may struggle if cases surge. Some local hospitals could get stretched.

4. Comorbidities & Vulnerable Populations

Elderly, immunocompromised, and those with chronic diseases remain at higher risk of complications even if average severity is lower.

5. Behavioural Fatigue & Complacency

After years of restrictions, many people are less vigilant about masking, distancing, or avoiding crowded indoor spaces. This reduces our buffer against surges.

6. Surveillance Gaps & Underreporting

Many mild or asymptomatic cases go undetected. The “true” incidence might be higher than official numbers suggest.

4. IMPACTS & NECESSARY RESPONSES / CORRECTIVE ACTIONS

Impacts (or potential impacts)

• Healthcare load: Increased hospitalizations or oxygen/bed demand, especially in hotspots.

• Workforce disruptions: Illness or quarantine can lead to staffing shortages.

• Supply chain stress: If infections cluster in factories, distribution, or logistic hubs.

• Public confidence and risk perception: Renewed fear can ripple through society and economies.

  
  

Corrective / Preparedness Measures

Revitalize vaccination campaigns

• Encourage boosters, especially for high-risk groups.

• Use updated vaccines tailored for currently circulating subvariants (when available).

• Close gaps in populations that are under-vaccinated.

  
  

Strengthen surveillance & genomic sequencing

• Monitor variants in real time.

• Increase sentinel site testing and wastewater surveillance.

  
  

Targeted non-pharmaceutical interventions (NPIs)

• Use masks in crowded or poorly ventilated indoor spaces.

• Promote hand hygiene, respiratory etiquette.

• Improve ventilation (open windows, air purifiers, exhaust systems).

  
  

Symptom-based isolation & testing protocols

• Isolate when symptomatic, especially in early days.

• Use rapid antigen tests or RT-PCR when indicated.

• No need for blanket lockdowns, instead focus on early detection and containment.

  
  

Resilience in institutions & workplaces

• Flexible work policies (remote or hybrid).

• Staggered shifts to reduce density.

• Awareness programs and health checks.

  
  

Protect high-risk settings & populations

• Senior homes, hospitals, immunocompromised centres need extra layers of protection.

• Prioritize prophylaxis, early treatment, masking in such settings.

  
  

Public communication & transparency

• Clear messaging about risk levels, variant updates, and recommended precautions.

• Combat misinformation actively.

  
  

Integrated health planning

• Keep COVID response integrated with other respiratory disease programs (influenza, RSV, etc.).

• Ensure supply chains for oxygen, antivirals, ventilators, PPE remain robust.

5. KEY TAKEAWAYS FOR SAFETY, RISK & CONTINUITY PROFESSIONALS

If you manage operations, risk, or safety in an organization, here’s what to internalize:

• Risk is dynamic: COVID is no longer static. Your continuity plans must allow flexibility to ramp up precautions when needed.

• Layered defences work best: No single measure is enough. Combine vaccination, masking, ventilation, testing, and behaviour adjustments.

• Scalable response triggers: Define thresholds or triggers (e.g. positivity rate, hospital admissions) that prompt escalation in precautions.

• Employee well-being is paramount: Beyond infection, consider mental health, burnout, and recovery protocols in your continuity strategy.

• Cross-dependency mapping matters: COVID impacts supply chains, third-party vendors, logistics, and utility services. Chart those interdependencies.

• Simulate mild-to-moderate surges: Run drills / tabletop exercises not just for extreme pandemics, but for realistic waves that stress systems for weeks.

• Communicate before it becomes a crisis: Transparency, clarity, and consistency in communication maintain trust during uncertain times.

  
  

6. CONCLUSION

COVID-19 in 2025 is not the catastrophic emergency we witnessed in 2020–21, but neither is it done with us. It has evolved into an endemic pathogen with surging cycles, variant evolution, and lingering risk, especially for vulnerable groups.

We are no longer in full-scale crisis mode but that does not mean zero risk. The present scenario demands steady vigilance, smart safeguards, and adaptive resilience. For organizations, the objective is not perfection but prepared agility: the ability to shift gears, scale up interventions, and protect operations, people, and reputation.

Take these lessons not just as health advisories, but as blueprints for continuity in a world where microbes, mobility, and human behaviour will always intersect.

Because the next wave or variant is only a matter of when, not if.
