Why is COVID-19 Rising in Asia?

It's mid-2025, and COVID-19 is still making a concerning comeback across Asia. A new wave of COVID-19 is spreading through parts of Southeast Asia, with countries like Hong Kong, Singapore, China, and Thailand all experiencing a noticeable increase in infections. Singapore, in particular, has reported a 28 percent rise in cases over the past year, reaching 14,200 cases as of May 3.

In this blog, let’s understand the reasons behind the rising COVID cases, what it means for you, and how you can stay safe.

The New COVID-19 Variants

JN.1 and Its Descendants

The primary cause of the current COVID-19 surge in Asia is the JN.1 variant, a descendant of the Omicron BA.2.86 lineage. It was first identified in Luxembourg in August 2023, and JN.1 has since spread globally. In Asia, it has evolved into subvariants like LF.7 and NB.1.8, which are now rapidly circulating in countries such as Singapore, Thailand, and China. 

These new strains are more transmissible, allowing them to spread more easily. However, current data suggests they do not cause more severe symptoms than earlier Omicron variants.

Why is COVID-19 increasing in Asia?

Here are some reasons for the Coronavirus spike in Asia- 

1. Low Immunity - Over time, protection from past infections or vaccines can weaken. This means that people can catch the virus again, even if they were previously protected.
2. More Travel and Gatherings - Since travel rules have become less strict and large events are resuming, more people are moving around and meeting each other, which facilitates the virus's spread more easily.
3. Relaxing Safety Rules- Many places have stopped requiring masks and social distancing. Without these safety measures, the virus has a better chance of spreading, leading to an increase in cases.
4. Seasonal Factors - The rise in cases occurs during warm weather, which is quite different from earlier periods. Earlier, people thought COVID-19 would spread more in cold months, like the flu, but the virus doesn't always follow that pattern.

Where Are the Cases Rising?

• Hong Kong- The number of COVID-19 cases has reached its highest level in over a year. The city has also reported a rise in severe cases and hospitalizations and urged its residents to follow preventive measures. 
• Singapore- Singapore has reported an increase in COVID-19 cases, rising from 11,100 to 14,200 in the week ending May 3, 2025. This 28% increase has also led to an increase in hospitalizations. However, ICU admissions have remained relatively stable. 
• Thailand- Thailand has reported a rise in COVID-19 cases, with over 71,000 infections and 19 deaths between January 1 and May 14, 2025. The XEC variant, a recombinant strain of Omicron, has been identified as a major factor in this surge. 
• China is experiencing a resurgence of COVID-19 cases, and the B. 1.8.1 variant, a descendant of the JN.1 variant, is responsible for this surge. This variant transmits rapidly, but current data suggest it does not cause severe illness. 

What is the situation in India?

India has witnessed a surge in COVID-19 cases, particularly in states such as Maharashtra, Kerala, Tamil Nadu, and Gujarat. As of May 19, 2025, the country reported 257 active cases, most of which are mild and not requiring hospitalization. Health authorities are monitoring the situation closely and have advised the public to remain vigilant.

Symptoms to Watch For

The symptoms of the JN.1 variant and its subvariants are similar to those of earlier Omicron strains- 

• Sore throat
• Fever
• Runny nose
• Dry cough
• Fatigue
• Headache
• Reduced taste or smell

These symptoms are typically mild and resolve within 4 to 5 days. If you experience these symptoms, it is advisable to get tested and follow local health guidelines.

How to Protect Yourself? 

Here are simple tips to reduce your risk of COVID-19 and protect yourself-

• Practice Good Hygiene

• Wash your hands regularly with soap and water.
• Use hand sanitizers.
• Avoid touching your face, your eyes, nose, and mouth.

• Wear Masks When Necessary

To reduce the spread of the virus, always wear a mask while going outside, especially in crowded or enclosed spaces.

• Get Vaccinated and Boosted

Ensure you're up to date with your COVID-19 vaccinations and boosters. Vaccination is one of the safest and most effective ways to prevent severe illness.

• Avoid Crowded Places

Limit your time in crowded or poorly ventilated areas, especially if you're at higher risk or in regions with high transmission rates.

• Stay Informed

Stay up-to-date with the latest news and updates. Rely on credible sources only, and do not panic. 

Is It Safe to Travel?

Traveling during this time is risky. However, if you're planning to travel to countries that have COVID-19 cases, here is what you need to know-

• Check the latest travel advisories and requirements of the country you are traveling to.
• Consider the COVID-19 situation in your destination.
• Follow all health protocols, including wearing masks and practicing hand hygiene.
• Avoid non-essential travel to high-risk areas.

Final Thoughts

Should you be worried? Well, you should not. The current COVID-19 wave is comparable to a seasonal flu outbreak for healthy and vaccinated individuals. Most cases are mild, and people typically recover without any serious complications.

However, older adults with weakened immune systems or other health issues should take extra care. If it has been over a year since your last vaccine, getting a booster dose is recommended. Always wearing a mask when going out in crowded places and avoiding travel when feeling sick are smart ways to lower your risk.

COVID-19 hasn't disappeared; it has become an endemic virus, similar to the flu, causing occasional waves. The current rise in Asia is a reminder to remain cautious, but there is no need to panic. This wave is being managed well with updated vaccines, common-sense safety measures, and strong healthcare support.
