Covid cases increase in Asia: What is causing the spike and what should we do? Doctors explain new symptoms

India and parts of Asia are witnessing a noticeable surge in COVID-19 cases. Health experts link this increase primarily to the emergence of new subvariants of the Omicron strain, particularly the JN.1 lineage.

What’s Causing the Spike?

Dr. Manisha Mendiratta, Associate Director & Head – Pulmonology, Sarvodaya Hospital, Faridabad, outlines several contributing factors:

1. Highly Transmissible Omicron Subvariant – JN.1

• The JN.1 variant is highly infectious and exhibits greater ability to evade immunity.

• Though not more lethal, it spreads rapidly, especially in populations with declining immunity.

• Symptoms tend to remain mild in vaccinated individuals.

2. Waning Immunity

• Many people in Asia received vaccines over a year ago.

• With low booster dose uptake, immunity has decreased over time.

• Vulnerable groups like the elderly and those with underlying health conditions are at increased risk.

3. Relaxation of COVID Protocols

• Mask-wearing, social distancing, and hygiene practices have significantly declined.

• Resumption of large public gatherings and international travel has increased opportunities for viral spread.

4. Seasonal and Environmental Factors

• Cooler weather is driving people indoors, where poor ventilation increases transmission risk.

• Underreporting due to reduced testing may mean the actual case count is much higher than reported.

Symptoms Associated with the JN.1 Variant

• Headache

• Sore throat

• Fever

• Dry cough

• Diarrhoea (more frequently observed with JN.1)

• Runny or blocked nose

• Fatigue or exhaustion

• Loss of taste or smell

What Should India Do?

Dr. Sandeep Budhiraja, Senior Director, Institute of Internal Medicine & Group Medical Director, Max Healthcare, advises the following:

• Remain vigilant and monitor incoming international travelers.

• Track the rise in flu-like illnesses to catch any unusual surges.

• Genomic surveillance testing is crucial, especially for symptomatic or at-risk individuals.

• Isolation is necessary when symptoms or positive tests arise.

“If the cases increase, we must reconsider our vaccination strategy, especially for high-risk groups such as the elderly, immunocompromised individuals, and those with chronic health conditions,” Dr. Budhiraja emphasized.

Preventive Measures Remain Crucial

Both experts reinforce the importance of continuing preventive practices:

• Regular hand washing

• Wearing masks in crowded places

• Social distancing

• Staying home if infected

“There is absolutely no need to panic. But we must stay alert in the coming weeks to assess how this outbreak progresses, especially across parts of Asia,” Dr. Budhiraja added.
