A new variant of the COVID-19 virus, named KP.2, has been detected in West Bengal, with thirty-six samples testing positive. This variant, an offshoot of Omicron, is driving an increase in Covid cases and is gradually replacing the JN.1 variant.
Health officials and experts have been monitoring this development closely, given its potential impact on public health.
Details of the KP.2 Variant
KOLKATA: The KP.2 variant, belonging to the FLiRT group of SARS-CoV2, has been identified through genomic sequencing in the last few weeks.
This variant has been found in about 50% of the samples, mainly from Kolkata, indicating a significant presence in the region.
The KP.2 variant is noted for its convergent evolution, which has resulted in it picking up a similar set of mutations to other variants within the FLiRT group, including KP.2, JN.1.7, and others.
Mild Symptoms and High Transmission Rate
Despite its high transmission rate, the KP.2 variant is causing only mild symptoms.
According to microbiologist Bhaskar Narayan Chaudhuri of Peerless Hospital, this variant has shown an ability to evade immunity conferred by previous infections or vaccinations but does not lead to severe illness.
“Covid has now turned into just another viral respiratory infection – milder than influenza and adenovirus infections, not to speak bacterial infections, which are much more severe, compared to Covid now,” Chaudhuri stated.
Health Officials’ Perspective
Health officials have noted that KP.2 is gradually replacing the JN.1 variant, which had been in circulation in Bengal for over four months.
A state health official commented, “While this offshoot is gradually replacing its parent JN.1, there is no reason to worry, as it causes only mild disease.”
National Context
The thirty-six KP.2-positive cases in West Bengal are part of 286 such cases across India, with Maharashtra recording the highest number.
Almost all samples sequenced at the National Institute of Biomedical Genomics in Kalyani originated from Kolkata. This indicates a localized surge that health authorities are closely monitoring.
Expert Opinions on the Surge
Infectious diseases specialist Yogiraj Ray from IPGMER emphasized that the emergence of new RNA virus strains is normal.
“There is no point pressing the panic button unless there is an increase in the number of severe infections and hypoxic patients (patients with low oxygen). I am not seeing such an increase,” Ray said.
Potential for Future Surges
Experts have suggested that the KP.2 variant could lead to another surge in cases, similar to those observed in December 2023 and January 2024.
However, state officials have assured that the current numbers do not constitute a significant surge, with only about 30 active cases across the state. Most hospitals in Kolkata do not have any positive in-patients, indicating that the healthcare system is not currently under significant strain.
Impact of Election Season
Health experts also pointed out that the election season could lead to a higher number of KP.2 infections, though many might go untested due to the mildness of the symptoms.
Immunologist Dipyaman Ganguly of CSIR-Indian Institute of Chemical Biology Kolkata remarked, “Till now, KP.2 has neither shown a widespread nor severe disease in detected cases. In my opinion, there is no imminent alarm.”
Wrap Up
While the detection of the KP.2 variant in West Bengal and other parts of India is noteworthy, health officials and experts emphasize that there is no cause for immediate alarm.
The variant, although highly transmissible, causes only mild symptoms and has not led to an increase in severe cases. Continuous monitoring and genomic sequencing will be essential in managing and understanding the spread and impact of this new Covid variant.
