With new variants of Covid emerging, this time we might be facing a group of mutants which have been collectively named as 'FLiRT'.
According to a report by Times of India, the variants which are the cause of the one-fourth Covid cases in the United States are - KP.2 and KP.1.1 under the FLiRT.
These variants have been named so due to the letters which were derived from their mutations, and they also happen to be the direct descendants of JN.1.
KP.2 is a descendent of the Omicron JN.1 strain and is surpassing JN.1 in countries such as the United States of America and the United Kingdom. Covid cases of FLiRT have been spreading quickly in the US and have also been detected in India.
Ninety-one cases of the new Covid subvariant KP.2 were detected in Maharashtra recently, following which experts allayed concerns about the variant causing issues in Karnataka.
According to TOI, the variant was found as a dominant strain in April, after the first cases were identified in January. More such cases have also been detected in Thane, Solapur, Pune, Amravati, Nashik, Ahmednagar, Aurangabad, Latur and Sanglione.
According to TOI, Chief of Research and Development at the Veterans Affairs St. Louis Healthcare System Dr Ziyad Al-Aly told NYT, "I don’t want to say that we already know everything about KP.2. But at this time, I’m not seeing any major indications of anything ominous."
Citing US CDC records, the publication reported that until March, the variants constituted only one per cent of the Covid cases, but after that the cover of the variant reached up to over one quarter of the total cases. Having three substitutions in the S protein, the KP.2 variant seems to be a descendant of the JN.1.
According to a Japanese study cited by TOI, KP.2 has a reproductive number which is 1.22-, 1.32- and 1.26- times, which is higher than JN.1, but in the infectivity rate, JN.1 beats KP.2.
According to TOI, the other variant under the FLiRT, KP.1.1 has not been widespread, as the US CDC data shows that 28 per cent of the Covid cases are due to KP.2 and only 7.1 per cent due to KP.1.1, of the total cases.
Allegedly KP.2 exceeds JN.1 in eluding immunity and is also slightly more infectious than the latter.
According to TOI, Dr David Ho who is a virologist at Columbia University, believes that KP.2 might infect those who have received the most updated vaccine as well.
According to the publication, symptoms caused by the FliRT variants includes - sore throat, coughing, fever, runny nose, head and body aches, chest congestion, fatigue and shortness of breath in severe cases.
To not get affected and to stay safe from Covid, preventive measures like wearing masks in public or crowded places, washing hands frequently to maintain hand hygiene, avoiding physical contact, disinfecting frequently touched surfaces, etc. can be adopted.
By following these simple tips, one can avoid the contraction and spread of the virus.
Due to the technical names that these mutations have, the variant has been named 'FLiRT'.
One of the variants under it as a mutation include letters 'F' and 'L' and the other's mutation includes letters 'R' and 'T'.
