India has recently reported 324 cases of the COVID-19 sub-variants KP.1 and KP.2, part of the JN.1 branch of the Omicron variant. This development, while noteworthy, has not led to a significant increase in hospitalisations or severe cases, according to the Indian SARS-CoV-2 Genomics Consortium (INSACOG) and news agency PTI. Here's a detailed look at what this means for India and what we need to know about these sub-variants.
Breakdown of Cases
According to INSACOG, the 324 reported cases are divided into 290 cases of the KP.2 sub-variant and 34 cases of the KP.1 sub-variant. KP.2 is notably more prevalent, with Maharashtra being the hardest-hit state, reporting 148 cases. The distribution of KP.2 cases across other states is as follows:
- West Bengal: 36 cases
- Gujarat: 23 cases
- Rajasthan: 21 cases
- Odisha: 17 cases
- Uttarakhand: 16 cases
- Goa: 12 cases
- Uttar Pradesh: 8 cases
- Karnataka: 4 cases
- Haryana: 3 cases
- Madhya Pradesh: 1 case
- Delhi: 1 case
For the KP.1 sub-variant, the majority of cases are concentrated in West Bengal, which has reported 23 out of the 34 cases. The distribution for other states is:
- Maharashtra: 4 cases
- Gujarat: 2 cases
- Rajasthan: 2 cases
- Goa: 1 case
- Haryana: 1 case
- Uttarakhand: 1 case
No Cause for Alarm
The report emphasises that there is no need for alarm despite the detection of these sub-variants. There has been no increase in severe cases or hospitalisations, indicating that the public health impact remains manageable. This situation reflects the nature of viruses like SARS-CoV-2, which mutate frequently.

Global Context
Globally, the sub-variants JN.1 and its lineages, including KP.1 and KP.2, are among the most prevalent COVID-19 strains. The World Health Organization (WHO) has classified KP.2 as a Variant Under Monitoring due to its spread and mutation characteristics.
Singapore's Experience
Singapore is currently experiencing a surge in COVID-19 cases driven by these sub-variants. The Ministry of Health (MOH) reported a significant increase in infections from May 5 to May 11, with cases rising to 25,900, almost doubling from the previous week’s count of 13,700. This surge has prompted Singaporean authorities to recommend the wearing of masks once more as a precautionary measure.
Monitoring and Response
INSACOG is actively monitoring the situation in India. Samples from hospitals are systematically selected to track any changes in the severity of COVID-19 cases. This proactive approach allows for the early detection of new variants and helps in formulating timely responses to mitigate the spread.

Importance of Vigilance
While there is no immediate cause for panic, maintaining vigilance is crucial. The nature of viruses to mutate means that new sub-variants can emerge, potentially with different characteristics in terms of transmissibility and severity. Public health authorities continue to stress the importance of following COVID-19 guidelines, including vaccination, mask-wearing in crowded places, and practising good hygiene.
Bottomline
India’s reporting of 324 cases of the KP.1 and KP.2 sub-variants of the Omicron strain is a reminder of the ongoing battle against COVID-19. Although these cases have not led to a surge in severe illness or hospitalisations, the situation underscores the importance of continued monitoring and adherence to public health measures. As global trends show, such as the spike in cases in Singapore, staying informed and prepared is essential in managing the pandemic effectively.
