COVID KP.3 Variant: What To Know About The Newest Strain

A new coronavirus variant is rising to dominance across the U.S. as experts warn of a potential ‘summer wave’ of COVID-19 cases. The new FLiRT variant, named KP.3, began spreading in June. Here’s all you need to know about it. 

The KP.3 variant is a sub-lineage of the JN.1, the major viral lineage circulating since December 2023, which arises from the Omicron variant. 

The common symptoms associated with KP.3 include fever or chills, cough, sore throat, congestion or runny nose, headache, muscle aches, difficulty breathing, fatigue, loss of taste or smell, brain fog and gastrointestinal symptoms such as upset stomach, mild diarrhoea and vomiting. These may appear two to 14 days after exposure.

Currently, it is estimated that KP.3 viruses make up between 16% and 37% of all SARS-CoV-2 virus cases in the United States. 

Most key COVID-19 indicators in the U.S. show low levels of activity of KP.3; therefore, experts believe that the total number of infections this variant may cause is likely low. However, it is very similar in terms of disease severity and can evade the immune system.

Experts suggest that everyone who is 6 months and older should get vaccinated for COVID-19 and maintain hygiene. The vaccine will help to protect against any serious illnesses from the virus.  Disclaimer: The content provided on the website is for informational purposes only and is not intended as a substitute for professional medical advice, diagnosis or treatment.
