New Delhi: With Southeast Asia witnessing a spike in COVID-19 infections, India too has reported a noticeable increase in cases, particularly in states like Kerala, Maharashtra, Gujarat, and Tamil Nadu. Fortunately, most infections remain mild, showing no signs of increased severity or death rates. Experts attribute the current surge to the emergence of the JN.1 sub-variant, which is part of the Omicron lineage. According to Dr. Jatin Ahuja, infectious disease expert at Indraprastha Apollo Hospitals in Delhi, JN.1 stems from the BA.2.86 or “Pirola” strain. Although the infection is highly transmissible and can bypass existing immunity, the symptoms continue to be similar to Omicron infections.
What is the JN.1 variant?
The JN.1 sub-variant belongs to the Omicron family and it carries 30 genetic alterations in the spike protein, the same it relies upon to enter human cells. These can help evade immune responses, allowing quick transmission. However, there is still no evidence of increased severity.
Is Covid vaccine immunity evading?
Doctors say that immunity from previous vaccines is likely wearing off, which is why exposure to Omicron activated immune responses. Memory B and T cells developed after vaccinations or previous infections continue to offer immunity, though. These minimise disease impact even with newer variants.
What are the symptoms of JN.1?
The symptoms of JN.1 are:
- Cough
- Fever
- Sore throat
- Nausea
- Conjunctivitis
Doctors say that isolation, rest, and hydration can be helpful for patients. Antiviral medication may also be prescribed in some cases. Experts also say that kidney disease, diabetes, and HIV AIDS can increase the odds of contracting the infection. Young children and pregnant women are also more prone to the infection.
Do you need another vaccination dose?
Doctors say that current vaccines can target previous strains, but they are less effective against JN.1. However, mRNA vaccines can give protection and adaptability. But due to limited access and exposure in India, it is still not quite acceptable. As a precautionary measure, one must wear masks, use a sanitiser, and maintain social distancing to stay safe.
