India has recorded 290 cases of the COVID-19 variant KP.2 and 34 cases of KP.1, according to the Indian SARS-CoV-2 Genomics Consortium (INSACOG). These sub-lineages, part of the JN1 variant, have been associated with a surge in cases in Singapore. INSACOG data shows that KP.1 cases have been detected across seven states and Union Territories (UTs), with West Bengal reporting the highest number at 23.
A source in the Union health ministry assured that these sub-variants have not led to an increase in hospitalizations or severe cases. The source emphasized that there is no reason for concern or panic, as mutations are a natural behavior of viruses like SARS-CoV-2. INSACOG’s surveillance is designed to detect new variants and monitor any changes in the severity of the disease.
The majority of KP.1 cases have been found in West Bengal (23), followed by Maharashtra (4), Rajasthan (2), Gujarat (2), and one each in Goa, Haryana, and Uttarakhand. In contrast, KP.2 cases are more widespread, with Maharashtra reporting the highest number at 148. Other states and UTs with KP.2 cases include West Bengal (36), Gujarat (23), Rajasthan (21), Uttarakhand (16), Odisha (17), Goa (12), Uttar Pradesh (8), Karnataka (4), Haryana (3), and one each in Delhi and Madhya Pradesh.
They are all sub variants of JN1 and there is no associated increase in hospitalization and severe cases. So there is no reason for concern or panic. The mutations will keep happening at a rapid pace and this is the natural behaviour of viruses like SARS-CoV2. The INSACOG surveillance is sensitive and is able to pick up the emergence of any new variant and samples are also picked from hospitals in a structured manner to detect any change in the severity of disease due to virusSource in the Union health ministry
Singapore is currently experiencing a new wave of COVID-19 , with over 25,900 cases recorded from May 5 to 11. KP.1 and KP.2 variants account for more than two-thirds of these cases. Singapore's Ministry of Health reported a sharp weekly spike in infections, which led the ministry to release a health advice suggesting mask use.
Globally, the predominant COVID-19 variants remain JN.1 and its sub-lineages, including KP.1 and KP.2. The World Health Organization has classified KP.2 as a Variant Under Monitoring. These strains originate from the Omicron variation and are collectively referred as "FLiRT" by scientists.
INSACOG's sensitive surveillance system is capable of identifying new variants and tracking changes in disease severity. This involves structured sample collection from hospitals. Despite the rapid pace of mutations, no increase in severe cases or hospitalizations has been linked to the KP.1 and KP.2 variants in India.
