CORONA UPDATE 2025 


While the world is still in the process of recovering from the early stages of the COVID-19 pandemic, the virus remains a persistent health issue, including the emergence of new strains. India, as of June 2025, is experiencing a small but significant increase in COVID-19 cases that are largely due to a new Omicron subvariant known as NB.1.8.1. Although the strain does not seem to result in more severe disease, its highly infectious nature has led to increased surveillance and public health notifications .


 IN INDIA 

After months of low COVID-19 cases, India has now witnessed a new surge in infections. As of June 1, 2025, there are 3,395 active cases in the country, a huge spike from April and early May.

Regional Breakdown

  • Kerala has emerged as the state with the highest number of active cases, reporting 1,336.

  • Maharashtra follows with 467 active cases.

  • Delhi has reported 375 cases, with two COVID-related deaths in the past 24 hours.

Health authorities have emphasized that although the absolute numbers remain manageable, the sudden spike is concerning because of the possibility of further spread if preventive measures are not reinforced.

What is the NB.1.8.1 Variant?

The recent surge in infections has been attributed to a new Omicron subvariant named NB.1.8.1. Initial estimates indicate that NB.1.8.1 is transmissible and appears to transmit more efficiently than previous Omicron subvariants.

Key Characteristics of NB.1.8.1

  • Increased transmissibility: The virus spreads rapidly in densely populated and enclosed environments.

  • Milder symptoms: Most patients report mild symptoms such as sore throat, cough, fever, fatigue, and nasal congestion.

  • Low hospitalization rates: Despite the rising case numbers, there has been no significant increase in hospital admissions or oxygen requirements.

  • Immune evasion: The subvariant shows some ability to evade immunity, especially in individuals who have not received booster doses or were last infected more than six months ago.

So far, NB.1.8.1 has not been classified by the World Health Organization (WHO) as a “variant of concern,” but it remains under monitoring due to its growing presence in parts of India and Southeast Asia.

Public Health Response

In light of the rising cases, both central and state governments in India have begun reinforcing basic health protocols.

Testing and Surveillance

  • States have been directed to increase RT-PCR testing in urban centers and among vulnerable populations.

  • Genomic sequencing efforts have been intensified to better track the spread of NB.1.8.1 and detect any further mutations.

  • Surveillance in public spaces, schools, and transportation hubs has been tightened.

Vaccination Campaigns

India’s vaccination program is now focused on booster doses, particularly for:

  • Elderly individuals (above 60 years)

  • People with chronic illnesses or immunodeficiencies

  • Healthcare and frontline workers

Updated vaccines that target newer Omicron variants have been made available in major cities, and rural vaccination drives are being revitalized.

Global Status and WHO Monitoring

Globally, COVID-19 case numbers remain relatively stable, but countries are keeping a close watch on new variants like NB.1.8.1. The WHO has issued fresh guidance encouraging all nations to:

  • Maintain variant monitoring through genomic testing.

  • Report significant outbreaks quickly and transparently.

  • Promote equitable access to updated vaccines and treatments.

Key Global Developments

  • United States: Some uptick in COVID-related emergency room visits, but no major outbreak yet linked to NB.1.8.1.

  • Europe: Steady low-level transmission with updated Omicron boosters available.

  • China: Authorities have introduced localized testing zones and monitoring programs in cities where minor case clusters have emerged.

Most countries have moved past large-scale lockdowns but retain contingency plans in case of significant surges.

Symptoms and When to Seek Help

With the current variant, symptoms are often mild but can vary. The most common symptoms include:


  • Fever or chills

  • Sore throat

  • Dry cough

  • Muscle aches

  • Headache

  • Fatigue

If symptoms worsen or if a person belongs to a high-risk group, medical advice should be sought promptly. Hospitals across India are prepared with isolation wards and oxygen supplies, but most patients are recovering at home.

Health Guidelines and Safety Measures

Health officials are advising the public to adopt the following preventive practices:

  • Mask up in crowded indoor areas and public transport.

  • Maintain hand hygiene through frequent washing and sanitizing.

  • Stay home when sick, and avoid contact with elderly or high-risk individuals if experiencing symptoms.

  • Get vaccinated, including booster doses if eligible.

Many offices, schools, and event organizers have reintroduced voluntary mask policies and are encouraging flexible attendance options.

Conclusion 

The NB.1.8.1 subvariant has produced a small surge of COVID-19 cases in India, but severity remains low overall. This is because healthcare is improved, there is a larger supply of vaccines, and there is greater awareness among the public. The rise is a reminder, though, that COVID-19 continues to evolve.


Staying alert, acting in the public good, and being accountable as a community will be critical in the coming months. The public is urged to remain well-informed and follow the most recent health authorities' guidance to prevent further complications.
