Health authorities across Europe are on high alert following the emergence of a new coronavirus variant, unofficially dubbed ‘Frankenstein,’ which has raised concerns due to its heightened transmissibility. This variant, scientifically known as KP.3, has seen infection rates quadruple in less than a month, signaling a potential surge in cases.
According to data from the U.S. Centers for Disease Control and Prevention (CDC), KP.3 now accounts for approximately 25% of new infections, up from just 7.1% a month ago. Experts warn that this strain can evade immunity provided by both vaccination and prior infection, making it particularly concerning.
The name ‘Frankenstein’ comes from the way the variant was formed — through a recombination of different strains, effectively adopting the most resilient traits from each. This genetic adaptability makes it more flexible and resistant, according to Dr. Eric Topol, director of the Scripps Research Translational Institute, who noted that KP.3 appears to be the most transmissible variant detected so far.
Symptoms associated with KP.3 are largely consistent with previous variants and include sore throat, runny or stuffy nose, dry or productive cough, fatigue, headache, muscle pain, fever or low-grade fever, sneezing, and occasional shortness of breath. Loss of smell or taste has become much rarer compared to earlier strains.
While early indicators suggest KP.3 does not cause more severe illness, its rapid spread could still overwhelm healthcare systems if case numbers rise significantly over the summer months.
The CDC is closely monitoring the spread of KP.3 and advises the public to remain cautious, especially in crowded or enclosed spaces. Although no new restrictive measures are currently planned, officials encourage vulnerable groups to stay informed and consider booster shots when eligible. Additionally, updated vaccines targeting the latest variants, including KP.3, are expected this fall.
