Symptoms, signs of new COVID-19 variant spreading 7 times faster than seasonal flu

As of May 2025, a new COVID-19 variant known as JN.1 has been spreading rapidly in several countries, including Singapore, India, Hong Kong, and Thailand. This variant is part of the Omicron lineage and is considered a "variant of interest" by health authorities due to its increased transmissibility compared to previous strains.
Symptoms of the JN.1 Variant
The symptoms associated with the JN.1 variant are similar to those of earlier Omicron subvariants and typically include:
-
Cough
-
Sore throat
-
Runny or congested nose
-
Fatigue
-
Muscle aches
-
Headache
-
Fever
-
Nausea or vomiting
-
Diarrhea
-
Loss of taste or smell (less common)
These symptoms usually appear within 2 to 14 days after exposure to the virus.
Severity and Spread
Despite its rapid spread, the severity of illness caused by the JN.1 variant remains relatively mild for most individuals, especially those who are vaccinated. However, there has been a slight increase in hospital admissions in some regions, indicating that the variant may pose a higher risk to certain populations.
The JN.1 variant is spreading more quickly than seasonal flu, with cases rising significantly in countries like Singapore and Thailand.
Preventive Measures
To reduce the risk of infection and transmission of the JN.1 variant, health authorities recommend the following precautions:
-
Vaccination: Stay up to date with COVID-19 vaccinations, including booster doses, to enhance immunity.
-
Mask-Wearing: Wear masks in crowded or enclosed spaces to reduce the spread of respiratory droplets.
-
Hand Hygiene: Regularly wash hands with soap and water or use hand sanitizers containing at least 60% alcohol.
-
Avoid Crowded Areas: Limit exposure to crowded places, especially in regions experiencing high transmission rates.
-
Stay Home When Sick: If you exhibit symptoms of COVID-19, stay home and avoid contact with others to prevent further spread.
Testing and Diagnosis
If you experience symptoms consistent with COVID-19, it's important to get tested promptly. Home antigen tests are widely available and can provide quick results. However, for more accurate diagnosis, especially if symptoms persist or worsen, consider visiting a healthcare facility for a PCR test.
Key Takeaways

The JN.1 variant is spreading faster than seasonal flu in several countries.

Symptoms are similar to previous Omicron variants and are generally mild.

Vaccination and preventive measures remain crucial in controlling the spread.
